title: Coronary heart disease in residents of Rochester, Minnesota. IV. Prognostic value of the resting electrocardiogram at the time of initial diagnosis of angina pectoris.
abstract: The data in this study were based on the 1,154 Rochester residents in whom a resting electrocardiogram had been obtained at the time of diagnosis of angina pectoris as the initial manifestation of coronary heart disease during the 26-year period 1950 through 1975. The finding of a normal electrocardiogram at the time of the initial diagnosis of angina pectoris was associated with a good prognosis. Survival at 5 years was equal to that expected, for the given age and sex distribution, under a cohort life table for the Minnesota white population. In contrast, in those patients who had an abnormal electrocardiogram at the time of diagnosis, the observed survival rate was 86% of that expected at 5 years.
