Natural History of Heart Disease from Epidemiological Investigation

Abstract

1. ST depression with negative T was the worst sign for prognosis in this study. 2. Then atrial fibrillation, negative T, RBBB and old myocardial infarction followed in this order. 3. The cause of death of the subjects with ECG abnormalities were closely related to myocardial infarction, sudden death and congestive heart failure and high frequency of cerebral hemorrhage were encountered in ST depression with negative T. 4. In our 10 years experience the incidence of ECG abnormalities and prognosis significantly depended upon high blood pressure. © 1972, The Japanese Circulation Society. All rights reserved.
