Abstract
We investigated the clinical characteristics of acute myocardial infar ction (AMI) not preceded by angina in 256 patients with first AMIs. Co mplications, including sustained ventricular tachycardia or ventricula r fibrillation. pump failure and cardiac rupture, were more frequent i n patients with AMI not preceded by angina (group 1, n = 92) than thos e preceded by angina (group 2, n = 164). The in-hospital mortality rat e was higher in group 1 than in group 2. Poor preexisting collateral c hannels or lack of ischemic preconditioning may be responsible for the poorer outcome in group 1 patients.
