The relationship between silent myocardial ischemia and sudden death depends on the severity and duration of the ischemia. Severe, transmural and persistent ischemia, as occurs in myocardial infarction, can trigger sudden death. When the ischemia is severe and transmural but not long-standing (e.g., Prinzmetal angina), ventricular arrhythmias appear frequently, but they are rarely malignant. In cases of subendocardial ischemia, there is no definitive proof of this relationship.
