pp 351-368

Abstract

The association between coronary risk factor and acute myocardial infarction was analized using data from a case-control study conducted in Buenos Aires, Argentina. A total of 1000 patients aged 30 to 65 who had been admitted for an acute myocardial infarction were included with their respectives controls' matched by sex and age. Relative risks of myocardial infarction were computed using a logistic regression. After adjustment for main risk factors for myocardial infarction the relative risks obtained were the following: male sex 1.4 (95 %, CI 1.0-1.9), family history of sudden death 1.8 (95%, CI 1.2-2.6), diabetes 2.0 (95%, CI 1.5-2.6), hypertension 2.2 (95 %, CI 1.8-2.8), current smokers: 15-25 cigarettes per day 1.9 (95 %, CI 1.1-3.1), more than 25 cigarettes per day 5.2 (95%, CI3.0-9.2) and body mass index: between 25-30 of 1.2 (95%, CI 1.0-1.5) and more than 30 of 1.7 (95 %, CI 1.3-2.4). This results show real data and allow us to have an authentic vision of the epidemiologic reality of our country; and contribute to medical information on this matter beyond our frontiers.
