Bleeding after reperfusion contributes to cardiac injury in MI


 

Final frontier

In an accompanying editorial, Colin Berry, MBChB, University of Glasgow, and Borja Ibáñez, MD, Jiménez Díaz Foundation University Hospital, Madrid, said they applaud the investigators for providing new, mechanistic insights into a difficult clinical problem that has an unmet therapeutic need.

But they pointed out that it is difficult to completely dissect the impact of hemorrhage versus MI size on adverse remodeling, noting that it might be the case that more severe ischemia/reperfusion events are associated with large MI sizes and higher degree of hemorrhage.

However, they concluded that: “Intramyocardial hemorrhage represents the final frontier for preventing heart failure post-MI. It is readily detected using CMR, and clinical research of novel therapeutic approaches merits prioritization.”
