A retrospective clinical study was done on 102 cases of acute myocardial infarction admitted to Severance hospital from January, 1972 through
December, 1976.
The following results,have been obtained:
L The ratio of male to female was 4.5: 1. Most patients were in the age group between the fifth and seven decades (85%) and the average,
age was 57 years.
2. The most common preceding risk factor was hypertention (37.3%). Diabetes,, angina pectoris and previous myocardial infarction were common in the order named.
3. The number of patients admitted annually increased markedly , in 1970´s as compared with 1960,s.
4.The mortality rate of 102 cases with acute myocardial, infarction was,18.6%´(19 cases).
5. The tjme Iapsed between the onset of symptoms: and admission to the hospital seems to be an, important determinant of the outcome in acutemyocardial infarction. Twenty one patients were admitted. within 4 hours after onset of symptoms and eight of them died with a mortally of The mortality rate declines: rapidly with larger delays of. admission from the time of onset;
6. The most common cause of death was cardiogenicshock.
Sudden cardiac arrest, congestive heart failure, and ventricular tachycardia were found in the order named.
7. The anterior wall infarction, was 63.7% of air cases, inferior wall 21.6%, anterior-inferior wall 9.8% and posterior wall 2.0%.
8. Arrhythmias were found in 49% and, conduction disturbances in 26.5% of all cases of acute myocardial infarction.
9. In view of the proven usefulness of coronarycare units for early detection, prevention and treatment of arrhythmias, it would be desirable, to set up at least one coronary care unit in Seoul, Korea.
