title: [Clinical characteristics of postinfarction left ventricular aneurysm with extensive calcification].
abstract: The authors experienced 4 cases of calcified postinfarction aneurysm of the left ventricle. They were all male, aged 55 to 71 (mean 64). Risk factor for coronary artery disease was only smoking in 2 patients, but there was none in the others. They had had acute anteroseptal or extensive anterior infarction at age 41-57 years (mean 49.3), and associated major cardiac events 10-22 years (mean 14.5) after acute myocardial infarction. Ventricular tachycardia, congestive heart failure and systemic thromboembolism were seen in 4, 2 and 1 patients respectively. However, none developed angina pectoris. In the 2 patients in whom signal-averaged electrocardiogram was performed, late potential was detected, so it was suspected that ventricular tachycardia could be due to reentry. Left ventricular end-diastolic pressure was elevated in all patients except one and ranged from 11 to 22 mmHg. Left ventricle was dilated in all cases and the end-diastolic volume index ranged from 143 to 503 ml/m2. The left ventricular ejection fraction ranged from 11 to 24%. However, in 2 of the 4 patients, the cardiac index was within normal limits, and evidence of congestive heart failure was absent. In 2 other patients with associated congestive heart failure, cardiac indices were 2.32, 1.56 l/min/m2 respectively. Coronary arteriogram showed a total occlusion in the left anterior descending (LAD) artery in all cases, and only the LAD artery was affected in 2 patients. In the remaining 2 patients, the right coronary arteries also were significantly stenotic or totally occluded, i.e., they had 2-vessel disease.(ABSTRACT TRUNCATED AT 250 WORDS)
