We investigated the clinical characteristics of acute myocardial infarction (AMI) not preceded by angina in 256 patients with first AMIs. Complications, including sustained ventricular tachycardia or ventricular fibrillation, pump failure and cardiac rupture, were more frequent in patients with AMI not preceded by angina (group 1, n = 92) than those preceded by angina (group 2, n = 164). The in-hospital mortality rate was higher in group 1 than in group 2. Poor preexisting collateral channels or lack of ischemic preconditioning may be responsible for the poorer outcome in group 1 patients.

D005260 Female Females
D006333 Heart Failure A heterogeneous condition in which the heart is unable to pump out sufficient blood to meet the metabolic need of the body. Heart failure can be caused by structural defects, functional abnormalities (VENTRICULAR DYSFUNCTION), or a sudden overload beyond its capacity. Chronic heart failure is more common than acute heart failure which results from sudden insult to cardiac function, such as MYOCARDIAL INFARCTION.
