Long-term prognosis in men and women coming to the emergency demartment with chest pain or other symptoms suggestive of acute myocardial infarction

• The aim of this study was to describe mortality, mode of death and risk indicators for death during 5 years of follow-up among men and women coming to the emergency department with chest pain or other symptoms raising suspicion of acute myocardial infarction (AMI). During the 21 months of the study, all patients who came to the medical emergency department of one single hospital with chest pain or other symptoms suggestive of AMI were prospectively followed for 5 years. A total of 5362 patients came on 7157 occasions; men accounted for 55% of the admissions. The 5-year mortality rate was 25.6% for men compared with 25.7% for women. The women were older and had a higher prevalence of known congestive heart failure and hypertension, whereas the prevalence of previous myocardial infarction was higher in men. When correcting for dissimilarities in age and clinical history, male gender appeared as an independent predictor of death. In terms of mode of death men differed from women: more frequently dying at home, more frequently dying in association with ventricular fibrillation and less frequently dying in association with congestive heart failure. However, these differences were to some extent explained by differences in age. Independent risk indicators for death during 5 years of follow-up differed in men and women. It was concluded that in a consecutive series of patients with chest pain or other symptoms suggesting AMI in the emergency department, male gender was an independent risk indicator for death during a 5-year follow-up. This might be explained by a higher occurrence of coronary artery disease in men than in women in this patient population.
