抄録

Severity of the coronary sclerosis was estimated in a total of 968 aged cases of consecutive autopsy. Incidence of myocardial infarction was elevated inn the high stenotic indices (sum of the coronary stenosis of the 3 vessels). There were 594 cases (61.4%) of balanced stenosis, 238 cases (24.6%) of unbalanced stenosis, and 136 cases (14.0%) of rare type (extreme difference of degree of stenosis between 3 vessels).<br>There were 155 cases (16.0%) of 3 vessel disease, 154 cases (15.9%) of 2 vessel disease, 215 cases (22.2%) of 1 vessel disease, and 444 cases 45.9% of no significant coronary sclerosis. Incidence of myocardial infarction in these 4 groups was 47.1%, 22.1%, 9.3%, and 2.3%, respectively.<br>The left anterior descending artery was the leading artery in 1 and 2 vessel diseases, followed by the right coronary artery and then the left circumflex coronary artery.
