However, conclusions from these reports have been varied and at times conflicting. These results prompted us to study the hospital records of a group of patients with myocardial infarction by linear discriminant analysis utilizing high-speed computer equipment, seeking a key to the riddle of prognosis. This report presents the analysis of the study. It is a report on data accumulated from past clinical records. Only the method of analysis is the result of a carefully designed statistical experiment.Material and MethodsĀ  Records of all patients with a diagnosis of acute myocardial infarction admitted between January, 1953, and January, 1960, to the University of Oklahoma Medical Center (including University Hospital, Veterans Administration Hospital, and Wesley Hospital) were reviewed. University Hospital is a state-owned teaching hospital which serves the State of Oklahoma on
