Cardiology

Many student athletes who test positive for COVID-19 likely can have an uneventful return to their sports after they have rested for 2 weeks in quarantine, doctors suggest.

There are reasons for caution, however, especially when a patient has symptoms that indicate possible cardiac involvement. In these cases, patients should undergo cardiac testing before a physician clears them to return to play, according to guidance from professional associations. Reports of myocarditis in college athletes who tested positive for SARS-CoV-2 but were asymptomatic are among the reasons for concern. Myocarditis may increase the risk of sudden death during exercise.

“The thing that you need to keep in mind is that this is not just a respiratory illness,” David T. Bernhardt, MD, professor of pediatrics, orthopedics, and rehabilitation at the University of Wisconsin in Madison, said in a presentation at the annual meeting of the American Academy of Pediatrics, held virtually this year. High school and college athletes have had cardiac, neurologic, hematologic, and renal problems that “can complicate their recovery and their return to sport.”

Still, children who test positive for COVID-19 tend to have mild illness and often are asymptomatic. “It is more than likely going to be safe for the majority of the student athletes who are in the elementary and middle school age to return to sport,” said Dr. Bernhardt. Given that 18-year-old college freshmen have had cardiac complications, there may be reason for more caution with high school students.
 

Limited data

The AAP has released interim guidance on returning to sports and recommends that primary care physicians clear all patients with COVID-19 before they resume training. Physicians should screen for cardiac symptoms such as chest pain, shortness of breath, fatigue, palpitations, or syncope.

Those with severe illness should be restricted from exercise and participation for 3-6 months. Primary care physicians, preferably in consultation with pediatric cardiologists, should clear athletes who experience severe illness.

“Most of the recommendations come from the fact that we simply do not know what we do not know with COVID-19,” Susannah Briskin, MD, a coauthor of the interim guidance, said in an interview. “We have to be cautious in returning individuals to play and closely monitor them as we learn more about the disease process and its effect on kids.”

Patients with severe illness could include those who were hospitalized and experienced hypotension or arrhythmias, required intubation or extracorporeal membrane oxygenation (ECMO) support, had kidney or cardiac failure, or developed multisystem inflammatory syndrome in children (MIS-C), said Dr. Briskin, a specialist in pediatric sports medicine at Case Western Reserve University, Cleveland.

“The majority of COVID-19 cases will not present like this in kids. We have no idea how common myocarditis is in kids post infection. We do know that, if anyone has chest pain, shortness of breath, excessive fatigue, syncope [passing out], or arrhythmia [feeling of their heart skipping beats], they should undergo further evaluation for myocarditis,” Dr. Briskin said.

Patients who are asymptomatic or have mild symptoms should rest for 14 days after their positive test. After their infectious period has passed, a doctor should assess for any concerning cardiac symptoms. “Anyone with prolonged fever or moderate symptoms should see their pediatrician and have an EKG performed, at a minimum, prior to return to sports,” Dr. Briskin said. “Anyone with an abnormal EKG or concerning signs or symptoms should be referred on to pediatric cardiology for a further assessment.”

Most patients who Dr. Briskin has seen have been asymptomatic or mildly symptomatic. “They have done well with a gradual return to physical activity,” she said. “We recommend a gradual return so individuals can be monitored for any signs or symptoms concerning for myocarditis. The far majority of individuals likely have an uneventful return to play.”

Mitigating risk

COVID-19 adds elements of uncertainty and complexity to the usual process of mitigating risk in sports, Dr. Bernhardt noted in his lecture. “You are dealing with an infection that we do not know a lot about,” he said. “And we are trying to mitigate risk not only for the individual who may or may not have underlying health problems, but you are also trying to mitigate risk for anybody else involved with the sport, including athletic trainers and team physicians, coaches, spectators, custodial staff, people working at a snack shack, and all the other people that can be involved in a typical sporting type of atmosphere.”

When patients do return to play after an illness, they should gradually increase the training load to avoid injury. In addition, clinicians should screen for depression and anxiety using tools such as the Four-Item Patient Health Questionnaire (PHQ-4) when they see patients. “The pandemic has been quite stressful for everybody, including our high school student athletes,” Dr. Bernhardt said. “Giving everybody a PHQ-4 when they come into clinic right now probably makes sense in terms of the stress levels that all of us are experiencing.”

If a patient screens positive, take additional history and refer for more in-depth mental health evaluation and treatment if warranted. Sharing breathing and relaxation exercises, promoting healthy behaviors, and paying attention to unhealthy strategies also may help, Dr. Bernhardt suggested.

Ultimately, determining when an athlete with COVID-19 can be medically cleared to return to play may be a challenge. There are limited data on epidemiology and clinical presentations that could help identify cardiac injury related to the disease, Dr. Bernhardt said. Guidance from the American College of Cardiology provides a framework for evaluating athletes for return to play, and pediatric cardiologists have discussed how the guidance relates to a pediatric population. Cardiac assessments may include measures of biomarkers such as troponin, B-type natriuretic peptide, and sedimentation rate, along with electrocardiograms, echocardiograms, and cardiac MRI.

Beyond return-to-play decisions, encourage the use of cloth face coverings on the sidelines and away from the playing field, and stress proper quarantining, Dr. Briskin added. Too often, she hears about children not quarantining properly. “Individuals with a known exposure should be quarantined in their house – ideally in a separate room from everyone else. ... When they come out of their room, they should wash their hands well and wear a cloth face covering. They should not be eating with other people.”

Dr. Bernhardt had no relevant disclosures.

Background: A previous study reported that a median of 5.6 years of intensive versus standard glucose lowering in veterans with type 2 diabetes resulted in significantly reduced risk of major cardiovascular events after 10 years of combined intervention and observational follow-up. 

Over a period of 15 years of combined intervention and posttrial follow-up, the risks of major cardiovascular events or death were not lower in the intensive-therapy group (hazard ratio for composite outcome, 0.91; 95% confidence interval, 0.78-1.06; P = .23; HR for death, 1.02; 95% CI, 0.88-1.18). The risk of major cardiovascular disease outcomes was reduced during the approximately 10-year interval of separation of the Hb A_1c curves (HR, 0.83; 95% CI, 0.70-0.99), but it did not persist after equalization of Hb A_1c levels (HR, 1.26; 95% CI, 0.90-1.75). Limitations include the observational study design, the study population of mostly older men, and reliance on administrative data for outcomes.  

Bottom line: More than 5 years of intensive glucose lowering, compared with standard therapy, did not show significantly lower risks of cardiovascular events or mortality once the glycated hemoglobin curves equalized during follow-up in years 11-15.

Fifteen days. That’s how much time the American College of Cardiology (ACC) had to convert its annual conference, scheduled for the end of March this year in Chicago, into a virtual meeting for the estimated 17,000 people who had planned to attend.

Because of the coronavirus pandemic, Illinois announced restrictions on the size of gatherings on March 13, causing the ACC to pivot to an online-only model.

“One big advantage was that we already had all of our content planned,” Janice Sibley, the ACC’s executive vice president of education, told Medscape Medical News. “We knew who the faculty would be for different sessions, and many of them had already planned their slides.”

But determining how to present those hundreds of presentations at an online conference, not to mention addressing the logistics related to registrations, tech platforms, exhibit hall sponsors, and other aspects of an annual meeting, would be no small task.

As medical societies have pivoted from in-person annual conferences to online meetings during the COVID-19 pandemic, they have found that they are mostly up to the challenge of disseminating research results and clinical education on par with in-person presentations. But according to a Medscape poll, many physicians think that, while the virtual experience is worthwhile and getting better, it’s never going to be the same as spending several days on site, immersed in the experience of an annual meeting.

As one respondent commented, “I miss the intellectual excitement, the electricity in the room, when there is a live presentation that announces a major breakthrough.”
 

Large medical societies have an advantage

As ACC rapidly prepared for its virtual conference, the society first refunded all registration and expo fees and worked with the vendor partners to resolve the cancellation of rental space, food and beverage services, and decorating. Then they organized a team of 15 people split into three groups. One group focused on the intellectual, scientific, and educational elements of the virtual conference. They chose 24 sessions to livestream and decided to prerecord the rest for on-demand access, limiting the number of presenters they needed to train for online presentation.

A second team focused on business and worked with industry partners on how to translate a large expo into digital offerings. They developed virtual pages, advertisements, promotions, and industry-sponsored education.

The third team’s focus, Ms. Sibley said, was most critical, and the hardest: addressing socio-emotional needs.

“That group was responsible for trying to create the buzz and excitement we would have had at the event,” she said, “pivoting that experience we would have had in a live event to a virtual environment. What we were worried about was, would anyone even come?”

But ACC built it, and they did indeed come. Within a half hour of the opening session, nearly 13,000 people logged on from around the world. “It worked beautifully,” Ms. Sibley said.

By the end of the 3-day event, approximately 34,000 unique visitors had logged in for live or prerecorded sessions. Although ACC worried at first about technical glitches and bandwidth needs, everything ran smoothly. By 90 days after the meeting, 63,000 unique users had logged in to access the conference content.

ACC was among the first organizations forced to switch from an in-person to all-online meeting, but dozens of other organizations have now done the same, discovering the benefits and drawbacks of a virtual environment while experimenting with different formats and offerings. Talks with a few large medical societies about the experience revealed several common themes, including the following:

• Finding new ways to attract and measure attendance.
• Ensuring the actual scientific content was as robust online as in person.
• Realizing the value of social media in enhancing the socio-emotional experience.
• Believing that virtual meetings will become a permanent fixture in a future of “hybrid” conferences.

New ways of attracting and measuring attendance

Previous ways to measure meeting attendance were straightforward: number of registrations and number of people physically walking into sessions. An online conference, however, offers dozens of ways to measure attendance. While the number of registrations remained one tool – and all the organizations interviewed reported record numbers of registrations – organizations also used other metrics to measure success, such as “participation,” “engagement,” and “viewing time.”

ACC defined “participation” as a unique user logging in, and it defined “engagement” as sticking around for a while, possibly using chat functions or discussing the content on social media. The American Society of Clinical Oncology (ASCO) annual conference in May, which attracted more than 44,000 registered attendees, also measured total content views – more than 2.5 million during the meeting – and monitored social media. More than 8,800 Twitter users posted more than 45,000 tweets with the #ASCO20 hashtag during the meeting, generating 750 million likes, shares, and comments. The European League Against Rheumatism (EULAR) annual congress registered a record 18,700 delegates – up from 14,500 in 2019 – but it also measured attendance by average viewing time and visits by congress day and by category.

Organizations shifted fee structures as well. While ACC refunded fees for its first online meeting, it has since developed tiers to match fees to anticipated value, such as charging more for livestreamed sessions that allow interactivity than for viewing recordings. ASCO offered a one-time fee waiver for members plus free registration to cancer survivors and caregivers, discounted registration for patient advocates, and reduced fees for other categories. But adjusting how to measure attendance and charge for events were the easy parts of transitioning to online.
 

Priority for having robust content

The biggest difficulty for most organizations was the short time they had to move online, with a host of challenges accompanying the switch, said the executive director of EULAR, Julia Rautenstrauch, DrMed. These included technical requirements, communication, training, finances, legal issues, compliance rules, and other logistics.

“The year 2020 will be remembered for being the year of unexpected transformation,” said a spokesperson from European Society for Medical Oncology (ESMO), who declined to be named. “The number of fundamental questions we had to ask ourselves is pages long. The solutions we have implemented so far have been successful, but we won’t rest on our laurels.”

ASCO had an advantage in the pivot, despite only 6 weeks to make the switch, because they already had a robust online platform to build on. “We weren’t starting from scratch, but we were sure changing the way we prepared,” ASCO CEO Clifford Hudis, MD, said.

All of the organizations made the breadth and quality of scientific and educational content a top priority, and those who have already hosted meetings this year report positive feedback.

“The rating of the scientific content was excellent, and the event did indeed fulfill the educational goals and expected learning outcomes for the vast majority of delegates,” EULAR’s Dr. Rautenstrauch said.

“Our goal, when we went into this, was that, in the future when somebody looks back at ASCO20, they should not be able to tell that it was a different year from any other in terms of the science,” Dr. Hudis said.
 

Missing out on networking and social interaction

Even when logistics run smoothly, virtual conferences must overcome two other challenges: the loss of in-person interactions and the potential for “Zoom burnout.”

“You do miss that human contact, the unsaid reactions in the room when you’re speaking or providing a controversial statement, even the facial expression or seeing people lean in or being distracted,” Ms. Sibley said.

Taher Modarressi, MD, an endocrinologist with Diabetes and Endocrine Associates of Hunterdon in Flemington, N.J., said all the digital conferences he has attended were missing those key social elements: “seeing old friends, sideline discussions that generate new ideas, and meeting new colleagues. However, this has been partly alleviated with the robust rise of social media and ‘MedTwitter,’ in particular, where these discussions and interactions continue.”

To attempt to meet that need for social interaction, societies came up with a variety of options. EULAR offered chatrooms, “Meet the Expert” sessions, and other virtual opportunities for live interaction. ASCO hosted discussion groups with subsets of participants, such as virtual meetings with oncology fellows, and it plans to offer networking sessions and “poster walks” during future meetings.

“The value of an in-person meeting is connecting with people, exchanging ideas over coffee, and making new contacts,” ASCO’s Dr. Hudis said. While virtual meetings lose many of those personal interactions, knowledge can also be shared with more people, he said.

The key to combating digital fatigue is focusing on opportunities for interactivity, ACC’s Ms. Sibley said. “When you are creating a virtual environment, it’s important that you offer choices.” Online learners tend to have shorter attention spans than in-person learners, so people need opportunities to flip between sessions, like flipping between TV channels. Different engagement options are also essential, such as chat functions on the video platforms, asking questions of presenters orally or in writing, and using the familiar hashtags for social media discussion.

“We set up all those different ways to interact, and you allow the user to choose,” Ms. Sibley said.

Some conferences, however, had less time or fewer resources to adjust to a virtual format and couldn’t make up for the lost social interaction. Andy Bowman, MD, a neonatologist in Lubbock, Tex., was supposed to attend the Neonatal & Pediatric Airborne Transport Conference sponsored by International Biomed in the spring, but it was canceled at the last minute. Several weeks later, the organizers released videos of scheduled speakers giving their talks, but it was less engaging and too easy to get distracted, Dr. Bowman said.

“There is a noticeable decrease in energy – you can’t look around to feed off other’s reactions when a speaker says something off the wall, or new, or contrary to expectations,” he said. He also especially missed the social interactions, such as “missing out on the chance encounters in the hallway or seeing the same face in back-to-back sessions and figuring out you have shared interest.” He was also sorry to miss the expo because neonatal transport requires a lot of specialty equipment, and he appreciates the chance to actually touch and see it in person.
 

Advantages of an online meeting

Despite the challenges, online meetings can overcome obstacles of in-person meetings, particularly for those in low- and middle-income countries, such as travel and registration costs, the hardships of being away from practice, and visa restrictions.

“You really have the potential to broaden your reach,” Ms. Sibley said, noting that people in 157 countries participated in ACC.20.

Another advantage is keeping the experience available to people after the livestreamed event.

“Virtual events have demonstrated the potential for a more democratic conference world, expanding the dissemination of information to a much wider community of stakeholders,” ESMO’s spokesperson said.

Not traveling can actually mean getting more out of the conference, said Atisha Patel Manhas, MD, a hematologist/oncologist in Dallas, who attended ASCO. “I have really enjoyed the access aspect – on the virtual platform there is so much more content available to you, and travel time doesn’t cut into conference time,” she said, though she also missed the interaction with colleagues.

Others found that virtual conferences provided more engagement than in-person conferences. Marwah Abdalla, MD, MPH, an assistant professor of medicine and director of education for the Cardiac Intensive Care Unit at Columbia University Medical Center, New York, felt that moderated Q&A sessions offered more interaction among participants. She attended and spoke on a panel during virtual SLEEP 2020, a joint meeting of the American Academy of Sleep Medicine (AASM) and the Sleep Research Society (SRS).

“Usually during in-person sessions, only a few questions are possible, and participants rarely have an opportunity to discuss the presentations within the session due to time limits,” Dr. Abdalla said. “Because the conference presentations can also be viewed asynchronously, participants have been able to comment on lectures and continue the discussion offline, either via social media or via email.” She acknowledged drawbacks of the virtual experience, such as an inability to socialize in person and participate in activities but appreciated the new opportunities to network and learn from international colleagues who would not have been able to attend in person.

Ritu Thamman, MD, assistant professor of medicine at the University of Pittsburgh School of Medicine, pointed out that many institutions have cut their travel budgets, and physicians would be unable to attend in-person conferences for financial or other reasons. She especially appreciated that the European Society of Cardiology had no registration fee for ESC 2020 and made their content free for all of September, which led to more than 100,000 participants.

“That meant anyone anywhere could learn,” she said. “It makes it much more diverse and more egalitarian. That feels like a good step in the right direction for all of us.”

Dr. Modarressi, who found ESC “exhilarating,” similarly noted the benefit of such an equitably accessible conference. “Decreasing barriers and improving access to top-line results and up-to-date information has always been a challenge to the global health community,” he said, noting that the map of attendance for the virtual meeting was “astonishing.”

Given these benefits, organizers said they expect a future of hybrid conferences: physical meetings for those able to attend in person and virtual ones for those who cannot.

“We also expect that the hybrid congress will cater to the needs of people on-site by allowing them additional access to more scientific content than by physical attendance alone,” Dr. Rautenstrauch said.

Everyone has been in reactive mode this year, Ms. Sibley said, but the future looks bright as they seek ways to overcome challenges such as socio-emotional needs and virtual expo spaces.

Fifteen days. That’s how much time the American College of Cardiology (ACC) had to convert its annual conference, scheduled for the end of March this year in Chicago, into a virtual meeting for the estimated 17,000 people who had planned to attend.

Because of the coronavirus pandemic, Illinois announced restrictions on the size of gatherings on March 13, causing the ACC to pivot to an online-only model.

“One big advantage was that we already had all of our content planned,” Janice Sibley, the ACC’s executive vice president of education, told Medscape Medical News. “We knew who the faculty would be for different sessions, and many of them had already planned their slides.”

But determining how to present those hundreds of presentations at an online conference, not to mention addressing the logistics related to registrations, tech platforms, exhibit hall sponsors, and other aspects of an annual meeting, would be no small task.

As medical societies have pivoted from in-person annual conferences to online meetings during the COVID-19 pandemic, they have found that they are mostly up to the challenge of disseminating research results and clinical education on par with in-person presentations. But according to a Medscape poll, many physicians think that, while the virtual experience is worthwhile and getting better, it’s never going to be the same as spending several days on site, immersed in the experience of an annual meeting.

As one respondent commented, “I miss the intellectual excitement, the electricity in the room, when there is a live presentation that announces a major breakthrough.”
 

Large medical societies have an advantage

As ACC rapidly prepared for its virtual conference, the society first refunded all registration and expo fees and worked with the vendor partners to resolve the cancellation of rental space, food and beverage services, and decorating. Then they organized a team of 15 people split into three groups. One group focused on the intellectual, scientific, and educational elements of the virtual conference. They chose 24 sessions to livestream and decided to prerecord the rest for on-demand access, limiting the number of presenters they needed to train for online presentation.

A second team focused on business and worked with industry partners on how to translate a large expo into digital offerings. They developed virtual pages, advertisements, promotions, and industry-sponsored education.

The third team’s focus, Ms. Sibley said, was most critical, and the hardest: addressing socio-emotional needs.

“That group was responsible for trying to create the buzz and excitement we would have had at the event,” she said, “pivoting that experience we would have had in a live event to a virtual environment. What we were worried about was, would anyone even come?”

But ACC built it, and they did indeed come. Within a half hour of the opening session, nearly 13,000 people logged on from around the world. “It worked beautifully,” Ms. Sibley said.

By the end of the 3-day event, approximately 34,000 unique visitors had logged in for live or prerecorded sessions. Although ACC worried at first about technical glitches and bandwidth needs, everything ran smoothly. By 90 days after the meeting, 63,000 unique users had logged in to access the conference content.

ACC was among the first organizations forced to switch from an in-person to all-online meeting, but dozens of other organizations have now done the same, discovering the benefits and drawbacks of a virtual environment while experimenting with different formats and offerings. Talks with a few large medical societies about the experience revealed several common themes, including the following:

• Finding new ways to attract and measure attendance.
• Ensuring the actual scientific content was as robust online as in person.
• Realizing the value of social media in enhancing the socio-emotional experience.
• Believing that virtual meetings will become a permanent fixture in a future of “hybrid” conferences.

New ways of attracting and measuring attendance

Previous ways to measure meeting attendance were straightforward: number of registrations and number of people physically walking into sessions. An online conference, however, offers dozens of ways to measure attendance. While the number of registrations remained one tool – and all the organizations interviewed reported record numbers of registrations – organizations also used other metrics to measure success, such as “participation,” “engagement,” and “viewing time.”

ACC defined “participation” as a unique user logging in, and it defined “engagement” as sticking around for a while, possibly using chat functions or discussing the content on social media. The American Society of Clinical Oncology (ASCO) annual conference in May, which attracted more than 44,000 registered attendees, also measured total content views – more than 2.5 million during the meeting – and monitored social media. More than 8,800 Twitter users posted more than 45,000 tweets with the #ASCO20 hashtag during the meeting, generating 750 million likes, shares, and comments. The European League Against Rheumatism (EULAR) annual congress registered a record 18,700 delegates – up from 14,500 in 2019 – but it also measured attendance by average viewing time and visits by congress day and by category.

Organizations shifted fee structures as well. While ACC refunded fees for its first online meeting, it has since developed tiers to match fees to anticipated value, such as charging more for livestreamed sessions that allow interactivity than for viewing recordings. ASCO offered a one-time fee waiver for members plus free registration to cancer survivors and caregivers, discounted registration for patient advocates, and reduced fees for other categories. But adjusting how to measure attendance and charge for events were the easy parts of transitioning to online.
 

Priority for having robust content

The biggest difficulty for most organizations was the short time they had to move online, with a host of challenges accompanying the switch, said the executive director of EULAR, Julia Rautenstrauch, DrMed. These included technical requirements, communication, training, finances, legal issues, compliance rules, and other logistics.

“The year 2020 will be remembered for being the year of unexpected transformation,” said a spokesperson from European Society for Medical Oncology (ESMO), who declined to be named. “The number of fundamental questions we had to ask ourselves is pages long. The solutions we have implemented so far have been successful, but we won’t rest on our laurels.”

ASCO had an advantage in the pivot, despite only 6 weeks to make the switch, because they already had a robust online platform to build on. “We weren’t starting from scratch, but we were sure changing the way we prepared,” ASCO CEO Clifford Hudis, MD, said.

All of the organizations made the breadth and quality of scientific and educational content a top priority, and those who have already hosted meetings this year report positive feedback.

“The rating of the scientific content was excellent, and the event did indeed fulfill the educational goals and expected learning outcomes for the vast majority of delegates,” EULAR’s Dr. Rautenstrauch said.

“Our goal, when we went into this, was that, in the future when somebody looks back at ASCO20, they should not be able to tell that it was a different year from any other in terms of the science,” Dr. Hudis said.
 

Missing out on networking and social interaction

Even when logistics run smoothly, virtual conferences must overcome two other challenges: the loss of in-person interactions and the potential for “Zoom burnout.”

“You do miss that human contact, the unsaid reactions in the room when you’re speaking or providing a controversial statement, even the facial expression or seeing people lean in or being distracted,” Ms. Sibley said.

Taher Modarressi, MD, an endocrinologist with Diabetes and Endocrine Associates of Hunterdon in Flemington, N.J., said all the digital conferences he has attended were missing those key social elements: “seeing old friends, sideline discussions that generate new ideas, and meeting new colleagues. However, this has been partly alleviated with the robust rise of social media and ‘MedTwitter,’ in particular, where these discussions and interactions continue.”

To attempt to meet that need for social interaction, societies came up with a variety of options. EULAR offered chatrooms, “Meet the Expert” sessions, and other virtual opportunities for live interaction. ASCO hosted discussion groups with subsets of participants, such as virtual meetings with oncology fellows, and it plans to offer networking sessions and “poster walks” during future meetings.

“The value of an in-person meeting is connecting with people, exchanging ideas over coffee, and making new contacts,” ASCO’s Dr. Hudis said. While virtual meetings lose many of those personal interactions, knowledge can also be shared with more people, he said.

The key to combating digital fatigue is focusing on opportunities for interactivity, ACC’s Ms. Sibley said. “When you are creating a virtual environment, it’s important that you offer choices.” Online learners tend to have shorter attention spans than in-person learners, so people need opportunities to flip between sessions, like flipping between TV channels. Different engagement options are also essential, such as chat functions on the video platforms, asking questions of presenters orally or in writing, and using the familiar hashtags for social media discussion.

“We set up all those different ways to interact, and you allow the user to choose,” Ms. Sibley said.

Some conferences, however, had less time or fewer resources to adjust to a virtual format and couldn’t make up for the lost social interaction. Andy Bowman, MD, a neonatologist in Lubbock, Tex., was supposed to attend the Neonatal & Pediatric Airborne Transport Conference sponsored by International Biomed in the spring, but it was canceled at the last minute. Several weeks later, the organizers released videos of scheduled speakers giving their talks, but it was less engaging and too easy to get distracted, Dr. Bowman said.

“There is a noticeable decrease in energy – you can’t look around to feed off other’s reactions when a speaker says something off the wall, or new, or contrary to expectations,” he said. He also especially missed the social interactions, such as “missing out on the chance encounters in the hallway or seeing the same face in back-to-back sessions and figuring out you have shared interest.” He was also sorry to miss the expo because neonatal transport requires a lot of specialty equipment, and he appreciates the chance to actually touch and see it in person.
 

Advantages of an online meeting

Despite the challenges, online meetings can overcome obstacles of in-person meetings, particularly for those in low- and middle-income countries, such as travel and registration costs, the hardships of being away from practice, and visa restrictions.

“You really have the potential to broaden your reach,” Ms. Sibley said, noting that people in 157 countries participated in ACC.20.

Another advantage is keeping the experience available to people after the livestreamed event.

“Virtual events have demonstrated the potential for a more democratic conference world, expanding the dissemination of information to a much wider community of stakeholders,” ESMO’s spokesperson said.

Not traveling can actually mean getting more out of the conference, said Atisha Patel Manhas, MD, a hematologist/oncologist in Dallas, who attended ASCO. “I have really enjoyed the access aspect – on the virtual platform there is so much more content available to you, and travel time doesn’t cut into conference time,” she said, though she also missed the interaction with colleagues.

Others found that virtual conferences provided more engagement than in-person conferences. Marwah Abdalla, MD, MPH, an assistant professor of medicine and director of education for the Cardiac Intensive Care Unit at Columbia University Medical Center, New York, felt that moderated Q&A sessions offered more interaction among participants. She attended and spoke on a panel during virtual SLEEP 2020, a joint meeting of the American Academy of Sleep Medicine (AASM) and the Sleep Research Society (SRS).

“Usually during in-person sessions, only a few questions are possible, and participants rarely have an opportunity to discuss the presentations within the session due to time limits,” Dr. Abdalla said. “Because the conference presentations can also be viewed asynchronously, participants have been able to comment on lectures and continue the discussion offline, either via social media or via email.” She acknowledged drawbacks of the virtual experience, such as an inability to socialize in person and participate in activities but appreciated the new opportunities to network and learn from international colleagues who would not have been able to attend in person.

Ritu Thamman, MD, assistant professor of medicine at the University of Pittsburgh School of Medicine, pointed out that many institutions have cut their travel budgets, and physicians would be unable to attend in-person conferences for financial or other reasons. She especially appreciated that the European Society of Cardiology had no registration fee for ESC 2020 and made their content free for all of September, which led to more than 100,000 participants.

“That meant anyone anywhere could learn,” she said. “It makes it much more diverse and more egalitarian. That feels like a good step in the right direction for all of us.”

Dr. Modarressi, who found ESC “exhilarating,” similarly noted the benefit of such an equitably accessible conference. “Decreasing barriers and improving access to top-line results and up-to-date information has always been a challenge to the global health community,” he said, noting that the map of attendance for the virtual meeting was “astonishing.”

Given these benefits, organizers said they expect a future of hybrid conferences: physical meetings for those able to attend in person and virtual ones for those who cannot.

COVID-19–positive patients undergoing an invasive strategy for acute coronary syndrome presented hours later than uninfected historical controls, had a far higher incidence of cardiogenic shock, and their in-hospital mortality rate was four- to fivefold greater, according to data from the Global Multicenter Prospective COVID–ACS Registry. These phenomena are probably interrelated, according to Anthony Gershlick, MBBS, who presented the registry results at the Transcatheter Cardiovascular Therapeutics virtual annual meeting.

“We know that increasing ischemic time leads to bigger infarcts. And we know that bigger infarcts lead to cardiogenic shock, with its known higher mortality,” said Dr. Gershlick, professor of interventional cardiology at the University of Leicester (England).

“These data suggest that patients may have presented late, likely due to COVID concerns, and they had worse outcomes. If these data are borne out, future public information strategies need to be reassuring, proactive, simple, and more effective because we think patients stayed away,” the cardiologist added. “There are important public information messages to be taken from these data about getting patients to come to hospital during such pandemics.”

He presented prospectively collected registry data on 144 patients with confirmed ST-elevation MI (STEMI) and 122 with non-ST–elevation MI (NSTEMI), all COVID-19 positive on presentation at 85 hospitals in the United Kingdom, Europe, and North America during March through August of 2020. Since the initial message to the public early in the pandemic in many places was to try to avoid the hospital, the investigators selected for their no-COVID comparison group the data on more than 22,000 STEMI and NSTEMI patients included in two British national databases covering 2018-2019.

The COVID-positive STEMI patients were significantly younger, had more comorbidities, and had a higher mean heart rate and lower systolic blood pressure at admission than the non-COVID STEMI control group. Their median time from symptom onset to admission was 339 minutes, compared with 178 minutes in controls. Their door-to-balloon time averaged 83 minutes, versus 37 minutes in the era before the pandemic.

“I suspect that’s got something to do with the donning and doffing of personal protective equipment,” he said at the meeting sponsored by the Cardiovascular Research Foundation.

The in-hospital mortality rates were strikingly different: 27.1% in COVID-positive STEMI patients versus 5.7% in controls. Bleeding Academic Research Consortium type 3-5 bleeding was increased as well, by a margin of 2.8% to 0.3%. So was stroke, with a 2.1% in-hospital incidence in COVID-positive STEMI patients and a 0.1% rate in the comparator arm.

“But the biggest headline here for me was that the cardiogenic shock rate was 20.1% in the COVID-positive patients versus 8.7% in the non-COVID STEMI patients,” the cardiologist continued.

The same pattern held true among the COVID-positive NSTEMI patients: They were younger, sicker, and slower to present to the hospital than the non-COVID group. The in-hospital mortality rate was 6.6% in the COVID-positive NSTEMI patients, compared with 1.2% in the reference group. The COVID-positive patients had a 2.5% bleeding rate versus 0.1% in the controls. And the incidence of cardiogenic shock was 5%, compared with 1.4% in the controls from before the pandemic.

“Even though NSTEMI is traditionally regarded as lower risk, this is really quite dramatic. These are sick patients,” Dr. Gershlick observed.

Nearly two-thirds of in-hospital deaths in COVID-positive ACS patients were cardiovascular, and three-quarters of those cardiovascular deaths occurred in patients with cardiogenic shock. Thirty-two percent of deaths in COVID-positive ACS patients were of respiratory causes, and 4.9% were neurologic.

Notably, the ischemic time of patients with cardiogenic shock who died – that is, the time from symptom onset to balloon deployment – averaged 1,271 minutes, compared with 441 minutes in those who died without being in cardiogenic shock.

Session comoderator Sahil A. Parikh, MD, director of endovascular services at Columbia University Medical Center in New York, commented, “One of the striking things that is resonating with me is the high incidence of cardiogenic shock and the mortality. It’s akin to what we’ve seen in New York.”

If these data are borne out, future public information strategies need to be reassuring, proactive, simple, and more effective because we think patients stayed away,” the cardiologist added. “There are important public information messages to be taken from these data about getting patients to come to hospital during such pandemics.”

He presented prospectively collected registry data on 144 patients with confirmed ST-elevation MI (STEMI) and 122 with non-ST–elevation MI (NSTEMI), all COVID-19 positive on presentation at 85 hospitals in the United Kingdom, Europe, and North America during March through August of 2020. Since the initial message to the public early in the pandemic in many places was to try to avoid the hospital, the investigators selected for their no-COVID comparison group the data on more than 22,000 STEMI and NSTEMI patients included in two British national databases covering 2018-2019.

The COVID-positive STEMI patients were significantly younger, had more comorbidities, and had a higher mean heart rate and lower systolic blood pressure at admission than the non-COVID STEMI control group. Their median time from symptom onset to admission was 339 minutes, compared with 178 minutes in controls. Their door-to-balloon time averaged 83 minutes, versus 37 minutes in the era before the pandemic.

“I suspect that’s got something to do with the donning and doffing of personal protective equipment,” he said at the meeting sponsored by the Cardiovascular Research Foundation.

The in-hospital mortality rates were strikingly different: 27.1% in COVID-positive STEMI patients versus 5.7% in controls. Bleeding Academic Research Consortium type 3-5 bleeding was increased as well, by a margin of 2.8% to 0.3%. So was stroke, with a 2.1% in-hospital incidence in COVID-positive STEMI patients and a 0.1% rate in the comparator arm.

“But the biggest headline here for me was that the cardiogenic shock rate was 20.1% in the COVID-positive patients versus 8.7% in the non-COVID STEMI patients,” the cardiologist continued.

The same pattern held true among the COVID-positive NSTEMI patients: They were younger, sicker, and slower to present to the hospital than the non-COVID group. The in-hospital mortality rate was 6.6% in the COVID-positive NSTEMI patients, compared with 1.2% in the reference group. The COVID-positive patients had a 2.5% bleeding rate versus 0.1% in the controls. And the incidence of cardiogenic shock was 5%, compared with 1.4% in the controls from before the pandemic.

“Even though NSTEMI is traditionally regarded as lower risk, this is really quite dramatic. These are sick patients,” Dr. Gershlick observed.

Nearly two-thirds of in-hospital deaths in COVID-positive ACS patients were cardiovascular, and three-quarters of those cardiovascular deaths occurred in patients with cardiogenic shock. Thirty-two percent of deaths in COVID-positive ACS patients were of respiratory causes, and 4.9% were neurologic.

Notably, the ischemic time of patients with cardiogenic shock who died – that is, the time from symptom onset to balloon deployment – averaged 1,271 minutes, compared with 441 minutes in those who died without being in cardiogenic shock.

Session comoderator Sahil A. Parikh, MD, director of endovascular services at Columbia University Medical Center in New York, commented, “One of the striking things that is resonating with me is the high incidence of cardiogenic shock and the mortality. It’s akin to what we’ve seen in New York.”

COVID-19–positive patients undergoing an invasive strategy for acute coronary syndrome presented hours later than uninfected historical controls, had a far higher incidence of cardiogenic shock, and their in-hospital mortality rate was four- to fivefold greater, according to data from the Global Multicenter Prospective COVID–ACS Registry. These phenomena are probably interrelated, according to Anthony Gershlick, MBBS, who presented the registry results at the Transcatheter Cardiovascular Therapeutics virtual annual meeting.

“We know that increasing ischemic time leads to bigger infarcts. And we know that bigger infarcts lead to cardiogenic shock, with its known higher mortality,” said Dr. Gershlick, professor of interventional cardiology at the University of Leicester (England).

Start most patients newly diagnosed with heart failure with reduced ejection fraction on the disorder’s four foundational drug regimens all at once, all on the day the diagnosis is made, Gregg C. Fonarow, MD, recommended.

Less than 2 months before Dr. Fonarow made that striking statement during the virtual annual meeting of the Heart Failure Society of America, investigators first reported results from the EMPEROR-Reduced trial at the European Society of Cardiology’s virtual annual meeting, showing that the sodium-glucose transporter 2 (SGLT2) inhibitor empagliflozin (Jardiance) successfully cut events in patients with heart failure with reduced ejection fraction (HFrEF). That report, a year after results from a similar trial (DAPA-HF) showed the same outcome using a different drug from the same class, dapagliflozin (Farxiga), cemented the SGLT2 inhibitor drug class as the fourth pillar for treating HFrEF, joining the angiotensin receptor neprilysin inhibitor (ARNI) class (sacubitril valsartan), beta-blockers (like carvedilol), and mineralocorticoid receptor antagonists (like spironolactone).

This rejiggering of the consensus expert approach for treating HFrEF left cardiologists wondering what sequence to use when starting this quadruple therapy. Within weeks, the answer from heart failure opinion leaders was clear:

“Start all four pillars simultaneously. Most patients can tolerate, and will benefit from, a simultaneous start,” declared Dr. Fonarow, professor and chief of cardiology at the University of California, Los Angeles.

His rationale? Patients get benefits from each of these drug classes “surprisingly early,” with improved outcomes in clinical trials appearing within a few weeks, compared with patients in control arms. The consequence is that any delay in starting treatment denies patients time with improved health status, function, and survival.

Study results documented that the four foundational drug classes can produce rapid improvements in health status, left ventricular size and shape, and make clinically meaningful cuts in both first and recurrent hospitalizations for heart failure and in mortality, Dr. Fonarow said. After 30 days on quadruple treatment, a patient’s relative risk for death drops by more than three-quarters, compared with patients not on these medications.

The benefits from each of the four classes involve distinct physiologic pathways and hence are not diminished by concurrent treatment. And immediate initiation avoids the risk of clinical inertia and a negligence to prescribe one or more of the four important drug classes. Introducing the four classes in a sequential manner could mean spending as long as a year to get all four on board and up-titrated to optimal therapeutic levels, he noted.

“Overcome inertia by prescribing [all four drug classes] at the time of diagnosis,” Dr. Fonarow admonished his audience.

The challenge of prescribing inertia

The risk for inertia in prescribing heart failure medications is real. Data collected in the CHAMP-HF (Change the Management of Patients with Heart Failure) registry from more than 3,500 HFrEF patients managed at any of 150 U.S. primary care and cardiology practices starting in late 2015 and continuing through 2017 showed that, among patients eligible for treatment with renin-angiotensin system (RAS) inhibition (with either ARNI or a single RAS inhibiting drug), a beta-blocker, and a mineralocorticoid receptor antagonist (MRA), 22% received all three drug classes. A scant 1% were on target dosages of all three drug classes, noted Stephen J. Greene, MD, in a separate talk at the meeting when he cited his published findings.

The sole formulation currently in the ARNI class, sacubitril/valsartan (Entresto) has in recent years been the poster child for prescribing inertia in HFrEF patients after coming onto the U.S. market for routine use in 2015. A review run by Dr. Greene of more than 9,000 HFrEF patients who were at least 65 years old and discharged from a hospital participating in the Get With the Guidelines–Heart Failure registry during October 2015–September 2017 showed that 8% of eligible patients actually received a sacubitril/valsartan prescription. Separate assessment of outpatients with HFrEF from the same era showed 13% uptake, said D. Greene, a cardiologist at Duke University, Durham, N.C.

Substantial gaps in prescribing evidence-based treatments to HFrEF patients have existed for the past couple of decades, said Dr. Greene. “Even a blockbuster drug like sacubitril/valsartan has been slow to implement.”
 

Quadruple therapy adds an average of 6 years of life

One of the most strongest arguments favoring the start-four-at-once approach was detailed in what’s quickly become a widely cited analysis published in July 2020 by a team of researchers led by Muthiah Vaduganathan, MD. Using data from three key pivotal trials they estimated that timely treatment with all four drug classes would on average produce an extra 6 years of overall survival in a 55-year old HFrEF patient, and an added 8 years free from cardiovascular death or first hospitalization for heart failure, compared with less comprehensive treatment. The analysis also showed a significant 3-year average boost in overall survival among HFrEF patients who were 80 years old when using quadruple therapy compared with the “conventional medical therapy” used on control patients in the three trials examined.

Dr. Greene called these findings “remarkable.”

“Four drugs use five mechanistic pathways to produce 6 added years of survival,” summed up Dr. Vaduganathan during a separate talk at the virtual meeting.

In addition to this substantial potential for a meaningful impact on patents’ lives, he cited other factors that add to the case for early prescription of the pharmaceutical gauntlet: avoiding missed treatment opportunities that occur with slower, step-wise drug introduction; simplifying, streamlining, and standardizing the care pathway, which helps avoid care inequities and disrupts the potential for inertia; magnifying benefit when comprehensive treatment starts sooner; and providing additive benefits without drug-drug interactions.

“Upfront treatment at the time of [HFrEF] diagnosis or hospitalization is an approach that disrupts treatment inertia,” emphasized Dr. Vaduganathan, a cardiologist at Brigham and Women’s Hospital in Boston.
 

New approaches needed to encourage quick uptake

“Efficacy alone has not been enough for efficient uptake in U.S. practice” of sacubitril/valsartan, other RAS inhibitors, beta-blockers, and MRAs, noted Dr. Greene.

He was more optimistic about prospects for relatively quick uptake of early SGLT2 inhibitor treatment as part of routine HFrEF management given all the positives that this new HFrEF treatment offers, including some “unique features” among HFrEF drugs. These include the simplicity of the regimen, which involves a single dosage for everyone that’s taken once daily; minimal blood pressure effects and no adverse renal effects while also producing substantial renal protection; and two SGLT2 inhibitors with proven HFrEF benefit (dapagliflozin and empagliflozin), which bodes well for an eventual price drop.

The SGLT2 inhibitors stack up as an “ideal” HFrEF treatment, concluded Dr. Greene, which should facilitate quick uptake. As far as getting clinicians to also add early on the other three members of the core four treatment classes in routine treatment, he conceded that “innovative and evidence-based approaches to improving real-world uptake of guideline-directed medical therapy are urgently needed.”

Following a heart attack, there appears to be a “modest” benefit of using flash glucose monitoring over fingerstick testing to monitor blood glucose levels in patients with type 2 diabetes being treated with insulin or a sulfonylurea, according to investigators of the LIBERATES trial.

The results showed a nonsignificant increase in the time that subjects’ blood glucose was spent in the target range of 3.9-10.00 mmol/L (70-180 mg/dL) 3 months after experiencing an acute coronary syndrome (ACS).

At best, flash monitoring using Abbott’s Freestyle Libre system was associated with an increase in time spent in range (TIR) of 17-28 or 48 minutes per day over self-monitoring of blood glucose (SMBG), depending on the type of statistical analysis used. There was no difference in glycated hemoglobin A1c levels between the two groups, but there was a trend for less time spent in hypoglycemia in the flash monitoring arm.

Viewers underwhelmed

“My overall impression is that the effects were less pronounced than anticipated,” Kare Birkeland, MD, PhD, a specialist in internal medicine and endocrinology at Oslo University Hospital, Rikshospitalet, Norway, observed after the findings were presented at the virtual annual meeting of the European Association for the Study of Diabetes.

Others who had watched the live session seemed similarly underwhelmed by the findings, with one viewer questioning the value of devoting an hour-and-a-half session to the phase 2 trial.

However, the session chair Simon Heller, BA, MB, BChir, DM, professor of clinical diabetes at the University of Sheffield, and trial coinvestigator, defended the detailed look at the trial’s findings, noting that it was worthwhile to present the data from the trial as it “really helps explain why we do phase 2 and phase 3 trials.”

Strong rationale for monitoring post-MI

There is a strong rationale for ensuring that blood glucose is well controlled in type 2 diabetes patients who have experienced a myocardial infarction, observed Robert Storey, BSc, BM, DM, professor of cardiology at the University of Sheffield. One way to do that potentially is through improved glucose monitoring.

“There’s clearly a close link between diabetes and the risk of MI: Both high and low HbA1c are associated with adverse outcome, and high and low glucose levels following MI are also associated with adverse outcome,” he observed, noting also that hypoglycemia was not given enough attention in post-ACS patients.

LIBERATES was a prospective, multicenter, parallel group, randomized controlled trial, explained the study’s statistician Deborah Stocken, PhD, professor of clinical trials research at the University of Leeds. There was “limited ability to blind the interventions,” so it was an open-label design.

“The patient population in LIBERATES was kept as inclusive and as pragmatic as possible to ensure that the results at the end of the trial are generalizable,” said Dr. Stocken. Patients with type 2 diabetes were recruited within 5 days of hospital admission for ACS, which could include both ST- and non-ST elevation MI. In all, 141 of a calculated 150 patients that would be needed were recruited and randomized to the flash monitoring (69) or SMBG (72) arm.

Dr. Stocken noted that early in the recruitment phase, the trials oversight committee recommended that Bayesian methodology should be used as the most robust analytical approach.

“Essentially, a Bayesian approach would avoid a hypothesis test, and instead would provide a probability of there being a treatment benefit for continuous monitoring. And if this probability was high enough, this would warrant further research in the phase 3 setting,” Dr. Stocken said.
 

What else was shown?

“We had a number of prespecified secondary endpoints, which to me are equally important,” said Ramzi Ajjan, MD, MMed.Sci, PhD, associate professor and consultant in diabetes and endocrinology at Leeds University and Leeds Teaching Hospitals Trust.

Among these was the TIR at days 16-30, which showed a 90-minute increase per day in favor of flash monitoring over SMBG. This “seems to be driven by those who are an insulin,” Dr. Ajjan said, adding that “you get almost a 3-hour increase in time in range in people who are on insulin at baseline, and you don’t see that in people who are on sulfonylurea.”

Conversely, sulfonylurea treatment seemed to drive the reduction in the time spent in hypoglycemia defined as 3.9 mmol/L (70 g/dL) at 3 months. For the whole group, there was a 1.3-hour reduction in hypoglycemia per day with flash monitoring versus SMBG, which increased to 2 hours for those on sulfonylureas.

There also was a “pattern of reduction” in time spent in hypoglycemia defined as less than 3.0 mmol/L (54 g/dL) both early on and becoming more pronounced with time.

“Flash glucose monitoring is associated with higher treatment satisfaction score, compared with SMBG,” Dr. Ajjan said.

Although A1c dropped in both groups to a similar extent, he noted that the reduction seen in the flash monitoring group was associated with a decrease in hypoglycemia.

There was a huge amount of data collected during the trial and there are many more analyses that could be done, Dr. Ajjan said. The outcome of those may determine whether a phase 3 trial is likely, assuming sponsorship can be secured.

The LIBERATES Trial was funded by grants from the UK National Institute for Health Research and Abbott Diabetes Care. None of the investigators were additionally compensated for their work within the trial. Dr. Stocken had no disclosures in relation to this trial. Dr. Ajjan has received research funding and other financial support from Abbott, Bayer, Eli Lilly, Johnson & Johnson, and Novo Nordisk.

Following a heart attack, there appears to be a “modest” benefit of using flash glucose monitoring over fingerstick testing to monitor blood glucose levels in patients with type 2 diabetes being treated with insulin or a sulfonylurea, according to investigators of the LIBERATES trial.

The results showed a nonsignificant increase in the time that subjects’ blood glucose was spent in the target range of 3.9-10.00 mmol/L (70-180 mg/dL) 3 months after experiencing an acute coronary syndrome (ACS).

At best, flash monitoring using Abbott’s Freestyle Libre system was associated with an increase in time spent in range (TIR) of 17-28 or 48 minutes per day over self-monitoring of blood glucose (SMBG), depending on the type of statistical analysis used. There was no difference in glycated hemoglobin A1c levels between the two groups, but there was a trend for less time spent in hypoglycemia in the flash monitoring arm.

Viewers underwhelmed

“My overall impression is that the effects were less pronounced than anticipated,” Kare Birkeland, MD, PhD, a specialist in internal medicine and endocrinology at Oslo University Hospital, Rikshospitalet, Norway, observed after the findings were presented at the virtual annual meeting of the European Association for the Study of Diabetes.

Others who had watched the live session seemed similarly underwhelmed by the findings, with one viewer questioning the value of devoting an hour-and-a-half session to the phase 2 trial.

However, the session chair Simon Heller, BA, MB, BChir, DM, professor of clinical diabetes at the University of Sheffield, and trial coinvestigator, defended the detailed look at the trial’s findings, noting that it was worthwhile to present the data from the trial as it “really helps explain why we do phase 2 and phase 3 trials.”

Strong rationale for monitoring post-MI

There is a strong rationale for ensuring that blood glucose is well controlled in type 2 diabetes patients who have experienced a myocardial infarction, observed Robert Storey, BSc, BM, DM, professor of cardiology at the University of Sheffield. One way to do that potentially is through improved glucose monitoring.

“There’s clearly a close link between diabetes and the risk of MI: Both high and low HbA1c are associated with adverse outcome, and high and low glucose levels following MI are also associated with adverse outcome,” he observed, noting also that hypoglycemia was not given enough attention in post-ACS patients.

Percutaneous mitral valve repair with the MitraClip appears to be a safe, effective, and life-saving new treatment for severe acute mitral regurgitation (MR) secondary to MI in surgical noncandidates, even when accompanied by cardiogenic shock, according to data from the international IREMMI registry.

“Cardiogenic shock, when adequately supported, does not seem to influence short- and mid-term outcomes, so the development of cardiogenic shock should not preclude percutaneous mitral valve repair in this scenario,” Rodrigo Estevez-Loureiro, MD, PhD, said in presenting the IREMMI (International Registry of MitraClip in Acute Myocardial Infarction) findings reported at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

Commentators hailed the prospective IREMMI data as potentially practice changing in light of the dire prognosis of such patients when surgery is deemed unacceptably high risk because medical management, the traditionally the only alternative, has a 30-day mortality of up to 50%.

Severe acute MR occurs in an estimated 3% of acute MIs, and in roughly 10% of patients who present with acute MI complicated by cardiogenic shock (CS). The impact of intervening with the MitraClip in an effort to correct the acute MR arising from MI with CS has previously been addressed only in sparse case reports. The new IREMMI study is easily the largest dataset to date detailing clinical and echocardiographic outcomes, Dr. Estevez-Loureiro of Alvaro Cunqueiro Hospital in Vigo, Spain, said at the meeting, sponsored by the Cardiovascular Research Foundation.

He reported on 93 consecutive patients who underwent MitraClip implantation for acute MR arising in the setting of MI, including 50 patients in CS at the time of the procedure. All 93 patients had been turned down by their surgical team because of extreme surgical risk. Three-quarters of the MIs showed ST-segment elevation. Only six patients had a papillary muscle rupture; in the rest, the mechanism of acute MR involved left ventricular global remodeling associated with mitral valve leaflet tethering. Percutaneous valve repair was performed at 18 expert valvular heart centers in the United States, Canada, Israel, and five European countries.
 

Procedural success

Time from MI to MitraClip implantation averaged 24 days in the CS patients and 33 days in the comparator arm without CS.

“These patients had been turned down for surgery, so the attending physicians generally followed a strategy of trying to cool them down with mechanical circulatory support and vasopressors. MitraClip wasn’t an option at the beginning, but after two or three failed weanings from all the possible therapies, then MitraClip becomes an option. This is one of the reasons why the time lapse between MI and the clip is so large,” the cardiologist explained.

Procedural success rates were similar in the two groups: 90% in those with CS and 93% in those without. However, average procedure time was significantly longer in the CS patients: 143 minutes versus 83 minutes in the patients without CS.

At baseline, 86% of the CS group had grade 4+ MR, similar to the 79% rate in the non-CS patients. Postprocedurally, 60% of the CS group were MR grade 0/1 and 34% were grade 2, comparable to the rates of 65% and 23% in the non-CS group.

At 3 months’ follow-up, 83.4% of the CS group had MR grade 2 or less, again not significantly different from the 90.5% rate in non-CS patients. Systolic pulmonary artery pressure was also similar: 39.6 mm Hg in the CS patients, 44 mm Hg in those without. While everyone was New York Heart Association functional class IV preprocedurally, 79.5% of the CS group were NYHA class I or II at 3 months, not significantly different from the 86.5% prevalence in the comparator arm.
 

Longer-term clinical outcomes

At a median follow-up of 7 months, the composite primary clinical outcome composed of all-cause mortality or heart failure rehospitalization did not differ between the two groups: a 28% rate in the CS group and 25.6% in non-CS patients. All-cause mortality occurred in 16% with CS and 9.3% without, again not a significant difference.

In a Cox regression analysis, neither surgical risk score, patient age, left ventricular geometry, nor CS was independently associated with the primary composite endpoint. Indeed, the only independent predictor of freedom from mortality or heart failure readmission at follow-up was procedural success, which is very much a function of the experience of the heart team, Dr. Estevez-Loureiro continued.

Michael A. Borger, MD, PhD, who comoderated the late-breaking clinical science session, was wowed by the IREMMI results.

“The mortality rates, I can tell you, compared to traditional surgical series of acute MR in the face of ACS [acute cardiogenic shock] are very, very respectable,” commented Dr. Borger, director of the cardiac surgery clinic at the Leipzig (Ger.) University Heart Center.

“Extremely impressive,” agreed discussant Vinayak N. Bapat, MD, a cardiothoracic surgeon and valve scientist at the Minneapolis Heart Institute Foundation. He posed a practical question: “Should we take from this presentation that patients should be stabilized with something like ECMO [extracorporeal membrane oxygenation] or Impella [left ventricular assist device], then transferred to an expert center for the procedure?”

“I think that the stabilization is essential in the patients with cardiogenic shock,” Dr. Estevez-Loureiro replied. “Unlike with surgery, it’s very difficult to establish a MitraClip procedure in a couple of hours in the middle of the night. You have to stabilize them and then treat for shock with ECMO, Impella, or both. I think they should be transferred to a center than can deliver the best treatment. In centers with less experience, patients can be put on mechanical support and transferred to an expert valve center, not only for MitraClip implantation, but for discussion of all the treatment possibilities, including surgery.”

At a press conference in which Dr. Estevez-Loureiro presented highlights of the IREMMI study, discussant Dee Dee Wang, MD, said the international coinvestigators “need to be applauded” for this study.

“Having these outcomes is incredible,” declared Dr. Wang, a structural heart disease specialist at the Henry Ford Health System, Detroit.

While this is an observational study, it’s a high-quality dataset with excellent methodology. And conducting a randomized trial in patients with such high surgical risk scores – the CS group had an average EuroSCORE II of 21 – would be extremely difficult, according to the cardiologist.

Dr. Estevez-Loureiro reported receiving research grants from Abbott and serving as a consultant to that company as well as Boston Scientific.

Intravascular lithotripsy proved highly effective, safe, and user friendly as an adjunct to stenting for severely calcified coronary lesions at 30 days of follow-up in the pivotal Disrupt CAD III study aimed at gaining U.S. regulatory approval.

The technology is basically the same as in extracorporeal lithotripsy, used for the treatment of kidney stones for more than 30 years: namely, transmission of pulsed acoustic pressure waves in order to fracture calcium. For interventional cardiology purposes, however, the transmitter is located within a balloon angioplasty catheter, Dean J. Kereiakes, MD, explained in presenting the study results at the Transcatheter Cardiovascular Research Therapeutics virtual annual meeting.

In Disrupt CAD III, intravascular lithotripsy far exceeded the procedural success and 30-day freedom from major adverse cardiovascular event (MACE) performance targets set in conjunction with the Food and Drug Administration. In so doing, the intravascular lithotripsy device developed by Shockwave Medical successfully addressed one of the banes of contemporary interventional cardiology: heavily calcified coronary lesions.

Currently available technologies targeting such lesions, including noncompliant high-pressure balloons, intravascular lasers, cutting balloons, and orbital and rotational atherectomy, often yield suboptimal results, noted Dr. Kereiakes, medical director of the Christ Hospital Heart and Cardiovascular Center in Cincinnati.

Severe vascular calcifications are becoming more common, due in part to an aging population and the growing prevalence of hypertension, diabetes, and renal insufficiency. Severely calcified coronary lesions complicate percutaneous coronary intervention. They’re associated with increased risks of dissection, perforation, and periprocedural MI. Moreover, heavily calcified lesions impede stent delivery and expansion – and stent underexpansion is the leading predictor of restenosis and stent thrombosis, he observed at the meeting, sponsored by the Cardiovascular Research Foundation. Disrupt CAD III was a prospective single-arm study of 384 patients at 47 sites in the United States and several European countries. All participants had de novo coronary calcifications graded as severe by core laboratory assessment, with a mean calcified length of 47.9 mm by quantitative coronary angiography and a mean calcium angle and thickness of 292.5 degrees and 0.96 mm by optical coherence tomography.

“It’s staggering, the level of calcification these patients had. It’s jaw dropping,” Dr. Kereiakes observed.

Intravascular lithotripsy was used to prepare these severely calcified lesions for stenting. The intervention entailed transmission of acoustic waves circumferentially and transmurally at 1 pulse per second through tissue at an effective pressure of about 50 atm. Patients received an average of 69 pulses.

This was not a randomized trial; there was no sham-treated control arm. Instead, the comparator group selected under regulatory guidance was comprised of patients who had received orbital atherectomy for severe coronary calcifications in the earlier, similarly designed ORBIT II trial, which led to FDA marketing approval of that technology.

Key outcomes

The procedural success rate, defined as successful stent delivery with less than a 50% residual stenosis and no in-hospital MACE, was 92.4% in Disrupt CAD III, compared to 83.4% for orbital atherectomy in ORBIT II. The primary safety endpoint of freedom from cardiac death, MI, or target vessel revascularization at 30 days was achieved in 92.2% of patients in the intravascular lithotripsy trial, versus 84.4% in ORBIT II.

The 30-day MACE rate of 7.8% in Disrupt CAD III was primarily driven by periprocedural MIs, which occurred in 6.8% of participants. Only one-third of the MIs were clinically relevant by the Society for Coronary Angiography and Intervention definition. There were two cardiac deaths and three cases of stent thrombosis, all of which were associated with known predictors of the complication. There was 1 case each of dissection, abrupt closure, and perforation, but no instances of slow flow or no reflow at the procedure’s end. Transient lithotripsy-induced left ventricular capture occurred in 41% of patients, but they were benign events with no lasting consequences.

The device was able to cross and deliver acoustic pressure wave therapy to 98.2% of lesions. The mean diameter stenosis preprocedure was 65.1%, dropping to 37.2% post lithotripsy, with a final in-stent residual stenosis diameter of 11.9%, with a 1.7-mm acute gain. The average stent expansion at the site of maximum calcification was 102%, with a minimum stent area of 6.5 mm².

Optical coherence imaging revealed that 67% of treated lesions had circumferential and transmural fractures of both deep and superficial calcium post lithotripsy. Yet outcomes were the same regardless of whether fractures were evident on imaging.

At 30-day follow-up, 72.9% of patients had no angina, up from just 12.6% of participants pre-PCI. Follow-up will continue for 2 years.

Outcomes were similar for the first case done at each participating center and all cases thereafter.

“The ease of use was remarkable,” Dr. Kereiakes recalled. “The learning curve is virtually nonexistent.”
 

The reaction

At a press conference where Dr. Kereiakes presented the Disrupt CAD III results, discussant Allen Jeremias, MD, said he found the results compelling.

“The success rate is high, I think it’s relatively easy to use, as demonstrated, and I think the results are spectacular,” said Dr. Jeremias, director of interventional cardiology research and associate director of the cardiac catheterization laboratory at St. Francis Hospital in Roslyn, N.Y.

Patients with COVID-19 who present with ST-segment elevation MI (STEMI) represent a unique, high-risk population with greater risks for in-hospital death and stroke, according to initial results from the North American COVID-19 ST-Segment Elevation Myocardial Infarction Registry (NACMI).

Although COVID-19–confirmed patients were less likely to undergo angiography than patients under investigation (PUI) for COVID-19 or historical STEMI activation controls, 71% underwent primary percutaneous coronary intervention (PCI).

“Primary PCI is preferable and feasible in COVID-19–positive patients, with door-to-balloon times similar to PUI or COVID-negative patients, and that supports the updated COVID-specific STEMI guidelines,” study cochair Timothy D. Henry, MD, said in a late-breaking clinical science session at TCT 2020, the Transcatheter Cardiovascular Therapeutics virtual annual meeting.

The multisociety COVID-specific guidelines were initially issued in April, endorsing PCI as the standard of care and allowing for consideration of fibrinolysis-based therapy at non-PCI capable hospitals.

Five previous publications on a total of 174 COVID-19 patients with ST-elevation have shown there are more frequent in-hospital STEMI presentations, more cases without a clear culprit lesion, more thrombotic lesions and microthrombi, and higher mortality, ranging from 12% to 72%. Still, there has been considerable controversy over exactly what to do when COVID-19 patients with ST elevation reach the cath lab, he said at the meeting sponsored by the Cardiovascular Research Foundation.

NACMI represents the largest experience with ST-elevation patients and is a unique collaboration between the Society for Cardiovascular Angiography and Interventions, Canadian Association of Interventional Cardiology, American College of Cardiology, and Midwest STEMI Consortium, noted Dr. Henry, who is medical director of the Lindner Center for Research and Education at the Christ Hospital, Cincinnati.

The registry enrolled any COVID-19–positive patient or person under investigation older than 18 years with ST-segment elevation or new-onset left bundle branch block on electrocardiogram with a clinical correlate of myocardial ischemia such as chest pain, dyspnea, cardiac arrest, shock, or mechanical ventilation. There were no exclusion criteria.

Data from 171 patients with confirmed COVID-19 and 423 PUI from 64 sites were then propensity-matched to a control population from the Midwest STEMI Consortium, a prospective, multicenter registry of consecutive STEMI patients.

The three groups were similar in sex and age but there was a striking difference in race, with 27% of African American and 24% of Hispanic patients COVID-confirmed, compared with 11% and 6% in the PUI group and 4% and 1% in the control group. Likewise, there was a significant increase in diabetes (44% vs. 33% vs. 20%), which has been reported previously with influenza.

COVID-19–positive patients, as compared with PUI and controls, were significantly more likely to present with cardiogenic shock before PCI (20% vs. 14% vs. 5%), but not cardiac arrest (12% vs. 17% vs. 11%), and to have lower left ventricular ejection fractions (45% vs. 45% vs. 50%).

They also presented with more atypical symptoms than PUI patients, particularly infiltrates on chest x-ray (49% vs. 17%) and dyspnea (58% vs. 38%). Data were not available for these outcomes among historic controls.

Importantly, 21% of the COVID-19 patients did not undergo angiography, compared with 5% of PUI patients and 0% of controls (P < .001), “which is much higher than we would expect or have suspected,” Dr. Henry said. Thrombolytic use was very uncommon in those undergoing angiography, likely as a result of the guidelines.

Very surprisingly, there were no differences in door-to-balloon times between the COVID-positive, PUI, and control groups despite the ongoing pandemic (80 min vs. 78 min vs. 86 min).

But there was clear worsening in in-hospital mortality in COVID-19–positive patients (32% vs. 12% and 6%; P < .001), as well as in-hospital stroke (3.4% vs. 2% vs. 0.6%) that reached statistical significance only when compared with historical controls (P = .039). Total length of stay was twice as long in COVID-confirmed patients as in both PUI and controls (6 days vs. 3 days; P < .001).

Following the formal presentation, invited discussant Philippe Gabriel Steg, MD, Imperial College London, said the researchers have provided a great service in reporting the data so quickly but noted that an ongoing French registry of events before, during, and after the first COVID-19 wave has not seen an increased death rate.

“Can you tease out whether the increased death rate is related to cardiovascular deaths or to COVID-related pneumonias, shocks, ARDSs [acute respiratory distress syndromes], and so on and so forth? Because our impression – and that’s what we’ve published in Lancet Public Health – is that the cardiovascular morality rate doesn’t seem that affected by COVID.”

Dr. Henry replied that these are early data but “I will tell you that patients who did get PCI had a mortality rate that was only around 12% or 13%, and the patients who did not undergo angiography or were treated with medical therapy had higher mortality. Now, of course, that’s selected and we need to do a much better matching and look at that, but that’s our goal and we will have that information,” he said.

During a press briefing on the study, discussant Renu Virmani, MD, president and founder of CVPath Institute, noted that, in their analysis of 40 autopsy cases from Bergamot, Italy, small intramyocardial microthrombi were seen in nine patients, whereas epicardial microthrombi were seen in only three or four.

“Some of the cases are being taken as being related to coronary disease but may be more thrombotic than anything else,” she said. “I think there’s a combination, and that’s why the outcomes are so poor. You didn’t show us TIMI flow but that’s something to think about: Was TIMI flow different in the patients who died because you have very high mortality? I think we need to get to the bottom of what is the underlying cause of that thrombosis.”

“Can you tease out whether the increased death rate is related to cardiovascular deaths or to COVID-related pneumonias, shocks, ARDSs [acute respiratory distress syndromes], and so on and so forth? Because our impression – and that’s what we’ve published in Lancet Public Health – is that the cardiovascular morality rate doesn’t seem that affected by COVID.”

Dr. Henry replied that these are early data but “I will tell you that patients who did get PCI had a mortality rate that was only around 12% or 13%, and the patients who did not undergo angiography or were treated with medical therapy had higher mortality. Now, of course, that’s selected and we need to do a much better matching and look at that, but that’s our goal and we will have that information,” he said.

During a press briefing on the study, discussant Renu Virmani, MD, president and founder of CVPath Institute, noted that, in their analysis of 40 autopsy cases from Bergamot, Italy, small intramyocardial microthrombi were seen in nine patients, whereas epicardial microthrombi were seen in only three or four.

“Some of the cases are being taken as being related to coronary disease but may be more thrombotic than anything else,” she said. “I think there’s a combination, and that’s why the outcomes are so poor. You didn’t show us TIMI flow but that’s something to think about: Was TIMI flow different in the patients who died because you have very high mortality? I think we need to get to the bottom of what is the underlying cause of that thrombosis.”

Patients with heart failure with preserved ejection fraction (HFpEF) who received sacubitril/valsartan in the PARAGON-HF trial had significant protection against progression of renal dysfunction in a prespecified secondary analysis.

The 2,419 patients with HFpEF who received sacubitril/valsartan (Entresto) had half the rate of the primary adverse renal outcome, compared with the 2,403 patients randomized to valsartan alone in the comparator group, a significant difference, according to the results published online Sept. 29 in Circulation by Finnian R. McCausland, MBBCh, and colleagues.

In absolute terms, sacubitril/valsartan treatment, an angiotensin-receptor/neprilysin inhibitor (ARNI), cut the incidence of the combined renal endpoint – renal death, end-stage renal disease, or at least a 50% drop in estimated glomerular filtration rate (eGFR) – from 2.7% in the control group to 1.4% in the sacubitril/valsartan group during a median follow-up of 35 months.

The absolute difference of 1.3% equated to a number needed to treat of 51 to prevent one of these events.

Also notable was that renal protection from sacubitril/valsartan was equally robust across the range of baseline kidney function.
 

‘An important therapeutic option’

The efficacy “across the spectrum of baseline renal function” indicates treatment with sacubitril/valsartan is “an important therapeutic option to slow renal-function decline in patients with heart failure,” wrote Dr. McCausland, a nephrologist at Brigham and Women’s Hospital in Boston, and colleagues.

The authors’ conclusion is striking because currently no drug class has produced clear evidence for efficacy in HFpEF.

On the other hand, the PARAGON-HF trial that provided the data for this new analysis was statistically neutral for its primary endpoint – a reduction in the combined rate of cardiovascular death and hospitalizations for heart failure – with a P value of .06 and 95% confidence interval of 0.75-1.01.

“Because this difference [in the primary endpoint incidence between the two study group] did not meet the predetermined level of statistical significance, subsequent analyses were considered to be exploratory,” noted the authors of the primary analysis of PARAGON-HF, as reported by Medscape Medical News.

Despite this limitation in interpreting secondary outcomes from the trial, the new report of a significant renal benefit “opens the potential to provide evidence-based treatment for patients with HFpEF,” commented Sheldon W. Tobe, MD, and Stephanie Poon, MD, in an editorial accompanying the latest analysis.

“At the very least, these results are certainly intriguing and suggest that there may be important patient subgroups with HFpEF who might benefit from using sacubitril/valsartan,” they emphasized.
 

First large trial to show renal improvement in HFpEF

The editorialists’ enthusiasm for the implications of the new findings relate in part to the fact that “PARAGON-HF is the first large trial to demonstrate improvement in renal parameters in HFpEF,” they noted.

“The finding that the composite renal outcome did not differ according to baseline eGFR is significant and suggests that the beneficial effect on renal function was indirect, possibly linked to improved cardiac function,” say Dr. Tobe, a nephrologist, and Dr. Poon, a cardiologist, both at Sunnybrook Health Sciences Centre in Toronto.

PARAGON-HF enrolled 4,822 HFpEF patients at 848 centers in 43 countries, and the efficacy analysis included 4,796 patients.

The composite renal outcome was mainly driven by the incidence of a 50% or greater drop from baseline in eGFR, which occurred in 27 patients (1.1%) in the sacubitril/valsartan group and 60 patients (2.5%) who received valsartan alone.

The annual average drop in eGFR during the study was 2.0 mL/min per 1.73m² in the sacubitril/valsartan group and 2.7 mL/min per 1.73m² in the control group.

Although the heart failure community was disappointed that sacubitril/valsartan failed to show a significant benefit for the study’s primary outcome in HFpEF, the combination has become a mainstay of treatment for patients with HFpEF based on its performance in the PARADIGM-HF trial.

And despite the unqualified support sacubitril/valsartan now receives in guidelines and its label as a foundational treatment for HFpEF, the formulation has had a hard time gaining traction in U.S. practice, often because of barriers placed by third-party payers.

PARAGON-HF was sponsored by Novartis, which markets sacubitril/valsartan (Entresto). Dr. McCausland has reported no relevant financial relationships. Dr. Tobe has reported participating on a steering committee for Bayer Fidelio/Figaro studies and being a speaker on behalf of Pfizer and Servier. Dr. Poon has reported being an adviser to Novartis, Boehringer Ingelheim, and Servier.
