A clinical study was made cn one hundred and forty-three cases of atherosclerotic heart disease seen at Kyungpook University Hospital during past 10 years, and the following data were obtained.
1. Atherosclerotic heart disease was more common in the male with male to female ratio being 3.2:7.. Over two thirds of them, their age was fifth and sixth decades.
2. In 58.7 per cent of all patients there were associated diseases. The two most frequently associated diseases were hypertension and diabetes mellitus, coach comprising 31.5 per cent and 7.6 per cent; respectively. ´
3. The cardinal symptoms were .chest pain, dyspnea, indigestion, and palpitation. And the so-called painless myocardial infarction was noted in 7 cases (:11.9 per cent).
4. Physical-exercise, mental stress, and meal were three major precipiting factors of attacks in all clinical situations. In myocardial infarction single cause triggered the attacks, ~Nhereas, one or more factors played in attacks of angina Pectoris.
5. The common arrhythmias including conduction dist:rbances and their incidence were: both atrial fibrillation and premature ventricular contraction, 6.3 per cent, junctional rhythm, 4.2 per cent, first degree atrioventricular block, 8.4 per cent, second degree atrioventricular block, 3.5 per´ cent, complete right bundle branch block, 7.7 per cent, and complete left bundle branch block, 4.9 per cent. Left ventricular hypertrophy pattern anti the finding consistent with left atrial enlargement were noted in 41.3 per cent and 12.6 per cent, respectively. Electrocardiographically, anterior wall was the most frequent site of infarction followed by posterior wall, each comprising 58.3 per cent and 30.6 per cent, respectively.
6. Complications were developed in 48.6 per cent of myocardial infarction and in 23.9 per cent of angina pectoris. Congestive heart failure and. arrhythmia including heart block `vere the major complications. In acute myocardial infarction congestive ;!~eart failure and arrhythmia were noted in :51.9 per cent and 16.7 per cent, respectively, whereas, in angina pectoris they were noted in 16. 4 per cent and 6 per cent, respectively.
