The following data were collected at the time of the infarction: duration and severity of chest pain, type of infarction and peak SGOT (serum glutamic oxaloacetic transaminase) level. The duration of chest pain has previously been shown to correlate with infarct size. Duration of chest pain, age and peak SGOT level were found to be the most important predictors of survival. None of the other independent variables contributed further to survival when the effects of duration of pain, age and SGOT level were taken into account. However, there was a significant association between pain duration and functional status. These data suggest that the duration of chest pain during first myocardial infarctions is a predictor of long-term prognosis and probably of functional status.
