Life-Threatening Ventricular Arrhythmias in Patients with Silent Myocardial Ischemia Due to Coronary Artery Spasm

Abstract

Silent myocardial ischemia due to coronary-artery spasm can initiate potentially fatal arrhythmias in patients without flow-limiting structural coronary-artery lesions. The role of silent ischemia, reperfusion, or both in the initiation of fatal arrhythmias in larger groups of patients with advanced coronary-artery lesions remains to be defined.
