The immediate care of threatening myocardial infarction in general practice.

Twenty to sixty per cent of myocardial infarctions go unrecognized by patient and doctor, and there is no way to exactly predict these at the moment. But they have a much lower long-term mortality rate than do clinical infarctions. As a rule, a myocardial infarction will be preceded by pain and the sooner this is dealt with, the greater the salvage rate.
