Increased risk of ventricular arrhythmias in survivors of out-of-hospital cardiac arrest with chronic total coronary occlusion.

BACKGROUND Chronic total occlusion (CTO) is common in out-of-hospital cardiac arrest (OHCA) survivors with coronary artery disease. It is unclear whether CTO contributes to ventricular arrhythmias in this population. OBJECTIVE This study sought to evaluate the impact of unrevascularized CTOs on the occurrence of appropriate implantable cardioverter… CONTINUE READING
