4837Coronary findings in sports-related compared to non sports-related sudden cardiac arrest

Background: Coronary artery disease (CAD) has been described as a frequent cause of sudden cardiac arrest (SCA). The description of CAD in sports-related SCA has been approached only through autopsy series. At the best of our knowledge, no systematic phenotyping of CAD in sports-related SCA has been done. Purpose: To compare coronary angiography findings in sports-related SCA victims to those of non-sports related SCA. Methods: Data was taken between May 2011 and March 2016 from the Paris Sudden Cardiac Death Expertise Center prospective registry that extensively includes all patients who present SCA in Paris and suburbs. Among SCA victims who underwent coronary angiography, sports-related SCA where matched on the basis of age and gender to a group of non sports-related SCA (1:3 ratio). Angiography findings of the two groups were compared. Significant CAD was defined by the presence of an >50% stenosis on at least one coronary artery. A culprit lesion was defined by the presence of a thrombus in the artery, a flow reduction < TIMI 3, and/or an acute coronary occlusion.
