- In 1,395 patients admitted to hospital between 1976 and 1981 due to suspected acute myocardial infarction, the 5-year mortality rate was related to whether they developed infarction or not during the first 3 days. In all, patients with definite myocardial infarction had a 5-year mortality rate of 33.4% as compared with 13.3% in patients not fulfilling the criteria for this diagnosis (p less than 0.001). When separately analyzing patients with no previous myocardial infarction before admission and discharged from hospital, the corresponding mortality rate was 24.1% for myocardial infarction patients versus 8.1% in nonmyocardial infarction patients (p less than 0.001). Among all patients with nonconfirmed myocardial infarction, those who partly fulfilled the criteria (possible myocardial infarction) had a 5-year mortality rate of 16.7% as compared with 12.0% in those in whom myocardial infarction was completely ruled out (p = 0.18). Independent risk factors for death among patients not developing early infarction were high age and a clinical history of previous myocardial infarction and smoking. We conclude that in this study the long-term prognosis among patients admitted to hospital due to suspected acute myocardial infarction was clearly related to whether they developed an infarction or not during the first 3 days in hospital.

- In 809 patients with a recent myocardial infarction, morbidity during 5-year follow-up was assessed. The overall 5-year mortality rate was 33% (39% in patients with larger infarcts and 26% in patients with smaller infarcts) as judged from maximum serum enzyme activity (p less than .001). In terms of morbidity, no significant association with estimated infarct size was observed. Patients with smaller infarcts tended to have a higher reinfarction rate and were rehospitalized more often, whereas a similar proportion of patients with large and small infarcts developed stroke. Among survivors, chest pain tended to be more common in patients having smaller infarcts, whereas symptoms of dyspnea and claudicatio intermittens were similar in both groups, as were smoking habits, work capability, and varying forms of medication. We thus conclude that during a 5-year follow-up after acute myocardial infarction, mortality, but not morbidity, was related to the original infarct size.
