Screening for hypertensive disorders of pregnancy is often incomplete



More education, improved screening tools needed

“Unfortunately, most CVD risk stratification scores such as the Framingham score do not include pregnancy complications, despite excellent evidence that pregnancy complications increase risk of CVD,” said Catherine M. Albright, MD, MS, of the University of Washington, Seattle, in an interview. “This is likely because these scores were developed primarily to screen for CVD risk in men. Given the rising incidence of hypertensive disorders of pregnancy and the clear evidence that this is a risk factor for future CVD, more studies like this one are needed in order to help guide patient and provider education,” said Dr. Albright, who was not involved in the study.

“It is generally well reported within the ob.gyn. literature about the increased lifetime CVD risk related to hypertensive disorders of pregnancy and we, as ob.gyns., always ask about pregnancy history because of our specialty, which gives us the opportunity to counsel about future risks,” she said.

“Women’s health [including during pregnancy] has been undervalued and underresearched for a long time,” with limited focus on pregnancy-related issues until recently, Dr. Albright noted. “This is clear in the attitudes and education of the primary care providers in this study,” she said.

A major barrier to screening in clinical practice has been that the standard screening guidelines for CVD (for example, those published by the United States Preventive Services Taskforce) have not included pregnancy history, said Dr. Albright. “Subsequently, these questions are not asked during routine annual visits,” she said. Ideally, “we should be able to leverage the electronic medical record to prompt providers to view a previously recorded pregnancy history or to ask about pregnancy history as a routine part of CVD risk assessment, and, of course, additional education outside of ob.gyn. and cardiology is needed,” she said.

The clinical takeaway from the current study is that “every annual visit with a person who has been pregnant is an opportunity to ask about and document pregnancy history,” Dr. Albright said. “After the completion of childbearing, many patients no longer see an ob.gyn., so other providers need to feel comfortable asking about and counseling about risks related to pregnancy complications,” she added.

“It is clear that adverse pregnancy outcomes pose lifetime health risks,” said Dr. Albright. “We will continue to look into the mechanisms of this through research. However, right now the additional research that is needed is to determine the optimal screening and follow-up for patients with a history of hypertensive disorders of pregnancy, as well as to examine how existing CVD-screening algorithms can be modified to include adverse pregnancy outcomes,” she emphasized.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Albright had no financial conflicts to disclose.
