title: Attributable risks for acute myocardial infarction in four countries of Latin America.
abstract: This multicenter case control study investigated, in four countries of America, the proportions of acute myocardial infarction (AMI) attributable to cholesterol, smoking, hypertension, body mass index, diabetes and family history of coronary heart disease (attributable risks, AR). AR were estimated using information from 1060 cases of AMI and 1071 controls from Argentina, 323 cases of AMI and 314 controls from Cuba, 200 cases of AMI and 200 controls from Mexico and 266 cases of AMI and 264 controls from Venezuela. AR were obtained from the prevalence of coronary risk factors in the cases and the corresponding Odds Ratio (OR) derived through appropriate multivariate models. The AR for AMI observed for hypercholesterolaemia were the following: Venezuela 27%, Mexico 3%, Cuba 30% and Argentina 36%; for diabetes: Venezuela 10%, Mexico 15%, Cuba 5% and Argentina 7% and for body mass Index: Venezuela 12%, Mexico 3%, Cuba 19% and Argentina 17%. The same risk factor may have a different attributable risk in different populations. Together, hypercholesterolaemia, hypertension, smoking, diabetes, body mass index and family history of coronary heart disease accounted for 76% of all cases of AMI in Venezuela, 70% in Mexico, 81% in Cuba and 79% in Argentina. The knowledge of attributable risks could have important implications for public health strategies, especially in those countries with limited health care resources.
