title: Survival after recovery from acute myocardial infarction. Two and five year prognostic indices.
abstract: A prognostic index for two year survival following recovery from acute myocardial infarction has been verified in an independent group of 105 patients. Five variables comprise the index: systolic blood pressure level on admission, highest blood urea nitrogen level in the cardiac care unit; atrial arrhythmias in the cardiac care unit; angina pectoris for more than three months or a previous myocardial infarction; and more than one ventricular ectopic beat per hour recorded on an 8 hour dynamic electrocardiogram during convalescence just prior to hospital discharge. One hundred twenty-six patients have also been followed for five or more years, and we now report a five year prognostic index. Discriminant analysis indicates that the same five variables, although weighted differently, continue to be significant for prognostic assessment and may be utilized in the identification of patients at high and lower risk.
