Two‐year survival after myocardial infarction

We have studied 773 consecutive cases (706 individuals) with definite myocardial infarction treated in the Coronary Care Unit at Danderyd Hospital in Stockholm during the period 1984-85. Hospital mortality was 12.9% in all patients and 8.9% in patients under 70 years of age. Six hundred and six patients were discharged from the hospital and followed up for 2 years. The 2-year mortality in ischaemic heart disease was 14.4% in all patients and 9.5% in patients under 70 years of age and, including all causes of death, 20.3% and 14.6%, respectively. Our policy for medical treatment included frequent use of beta-adrenergic blocking agents, even in heart failure, and restricted use of antiarrhythmic drugs and digitalis. A short delay of admission may have been beneficial for the result of different kinds of anti-ischaemic intervention. Furthermore, a routinely performed exercise ECG before discharge and after 6 weeks, as part of a structured follow-up, has improved our ability to detect complications at an early stage and to optimize medical treatment.
