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

Abstract
Silent myocardial ischemia in patients with coronary atherosclerosis is associated with an increased risk of adverse cardiac events, including sudden death. The relation between silent ischemia and the initiation of potentially fatal ventricular arrhythmias has not been defined, however.
