Ninety six hospital cases with acute myocardial infarction were analyzed for factors which seemed important to prognosis. Linear discriminant analysis utilizing computer was used for evaluating the severity of illness in acute myocardial infarction. The predictive accuracy of 26 patients received a dead score was 53.8 per cent and that of 70 patients received a living score was 95.7 per cent. Of 12 patients who received a dead score and were treated with anticoagulants, 3 died and of 14 untreated patients, 11 died. Of 66 control patients predicted to live, 64 lived. Among 101 outpatients who were followed up for 5 years, the cardiac death of patients treated with anticoagulants was 3.1 per cent and that of untreated group was 28.0 per cent.
