The reasons for the marked variability in expansion of myocardial infarcts are unknown. To examine this question, the hearts in 204 patients with a single myocardial infarct, autopsied at The Johns Hopkins Hospital and studied after coronary arteriography and fixation in distension, were reviewed. There were 58 (28%) hearts with marked infarct expansion, 34 (17%) with moderate expansion and 112 (55%) with no or minimal expansion. The degree of expansion was greater in larger, more transmural infarcts (p < 0.001). Infarcts with greater expansion had significantly more endocardial thrombus (p < 0.001) and endocardial fibroelastosis (p < 0.01). Larger heart weight and degree of left ventricular hypertrophy had a significant negative correlation with infarct expansion (p < 0.05). A markedly greater degree of expansion was noted in the 101 infarcts (50%) caused by lesions in the distribution of the left anterior descending coronary artery as compared with the 57 infarcts (28%) secondary to right coronary lesions and the 46 infarcts (23%) in the distribution of the left circumflex coronary artery (p < 0.001). |
