Abstract Angiotensin converting enzime gene polimorphisms Insertion/Deletion and cardiovascular risk factors in patients with acute myocardial infarction Introduction Traditional cardiovascular risk factors are widely studied and closely linked with the development of acute myocardial infarction, stroke and peripheral vascular disease. The underlying genetic background includes the angiotensin converting enzyme gene mutations. The main objective of this study is to establish an association between the polymorphism Insertion/Deletion of angiotensin converting enzyme in a group of patients with coronary artery disease. Methods. We performed a prospective, case-control study, in a group of patients with acute myocardial infarction referred to our center for coronary angiogram. Clinical information was obtained from medical records and personal interviews. DNA collecting and analysis of angiotensin converting enzyme I / D polymorphism, were done by molecular biology techniques as previously described. Results. We included 100 individuals, 33 cases and 67 controls. The average age was 43.16 years old; 87.7% were male. Body mass index was higher in cases (35.6) than in controls (24.8). Smoking (p <0.001), hypertension (p <0.001) and highfibrinogen levels (p <0.001) were significant factors associated with cardiovascular disease (OR 16.78, OR 5.63 and OR: 16.8, respectively). No association was found in the DD genotype between cases and controls, nor with hypertensive patients. An association was found between the levels of fibrinogen and II genotype (p <0.005). Angiographically, the anterior descending coronary artery was the most frequently affected vessel in this group. Conclusion. There was no association between the DD angiotensin converting enyme genotype and the presence of the cardiovascular disease. This first report opens the possibility of analyzing other angiotensin converting enyme polymorphisms in other thrombotic and thromboembolic diseases.
