Abstract

A Clinical study was done on 90 cases of acute myocardial infarction admitted to Busan Wallace Memorial Baptist Hospital from January, 1977 to Febuary, 1983. The following results have been obtained. 1) The ratio of male to female was 2.2:1. The most age group were 5th decades(35.6%) and over 5th decades(5th decades and 6th decades) were two-thirds of all age group. And annual incidency were increasing tendencies, in 1980-1982 than 1977-1979. 2) Between the preceding diseases and the risk factors, the most common cause was the smoking (60%). And other associated diseases and factors were hypertension(54.4%), hypercholesterolemia (43.8%), hyperlipidemia(51.4%) and angina pectoris (34.4%). 3) The most common inducing factor was physical exertion(33.3%). And others were emotional stress(23.3%), alcohol drinking(10%), rest and sleeping(5.6%). 4) The major symptoms of acute myocardial infarction were precordial or epigastric pain(96.7%), dyspnea(53.3%), radiating chest pain (51.7%) and painless infarction(3.3%). 5) On laboratory data, there were leukocytosis in 50.5% increased SGOT in 68.6%, increased serum LDH in 75.9% and cardiomegaly in chest x-ray film were 82 percents. 6) The ratio between the anterior and inferior infarction on EKG was 1.9:1. 7) When admission, normal sinus rhythms on EKG were 59 percents. And the common associated electrocardiographic abnormalities were ventricular premature beat (23.6%), atrial fibrillation(15.7%), first degree A-V block (15.7%), left ventricular hypertrophy(15.7%). The most common abnormality was ventricular premature beat(23.6%). 8) The mortality rate of acute myocardial infarction was 10 percents. The causes of death were heart failure(33.3%), ventricular arrhythmia(33.3%), sudden death (22.2%) and cardiogenic shock(11.1%).
