title: [Survival in acute myocardial infarction in a group of 369 patients consecutively admitted between 1988 and 1992. Analysis of risk factors and medical procedure].
abstract: A retrospective analysis without exclusion of 369 consecutive cases of myocardial infarction admitted between January 1988 and March 1992 studied the risk factors, previous medical history and treatment in this period during which medical practice seemed to be standardised with acknowledged benefits of thrombolysis, beta-blockade and aspirin therapy. The population observed is divided in three age groups (< 65, > 65 < 75 and > 75). A Cox model multivariate analysis for age, sex, diabetes, hypertension, hypercholesterolaemia, tobacco smoking, previous infarction, coronary artery disease and cardiac failure underlined the risk related to age which was 3.2 for patients 65-75 years of age and 4 for patients over 75 years of age. The risk was high in women (1.4), diabetes (1.5) and previous infarction (1.7). The excess mortality of the elderly age groups could also have been related to medical management as the most effective treatments were less commonly used. Thrombolysis was used in 44% of patients under 65 years of age but in only 9.7% of patients over 75 years; betablockers were prescribed in 77.6% of the younger but only in 27.4% of the older patients. The same tendency was observed in the administration of aspirin, with 81.6% receiving this drug in the younger patients compared to only 61% in older patients. Differences in survival at 6 months according to age (93.6%, 74% and 54.9%) show that there is a clearly defined therapeutic objective over 65 years of age with a large field of action and a probability of significant improvement in mortality and morbidity.
