[Myocardial infarction in young mexicans associated to metabolic syndrome].

BACKGROUND: Acute coronary diseases are catastrophic, especially in young patients.

OBJECTIVE: To determine the risk of metabolic syndrome (MS) for premature acute myocardial infarction (AMI), combined with familial, behavioral, and nutritional factors in the northeast of Mexico.

MATERIAL AND METHODS: This is a case control study of patients less than 47 years of age with no personal history of angina, AMI, or cerebrovascular disease. Cases corresponded to patients with AMI (incident and primary cases; n = 55) and controls were blood donors located at the same hospital (n = 55). Behavioral, nutritional, and cardiometabolic risk factors were measured. Multivariate logistic regression was used for estimating odds ratios (OR) and 95% confidence intervals (95% CI).

RESULTS: MS increased the risk for premature AMI (95% CI: 1.73-39.5) eightfold, followed by smoking (OR: 7.76; 95% CI: 1.27-47.3), family history of AMI or sudden death (OR: 11.0; 95% CI: 2.03-60.4), and sedentary lifestyle (OR: 2.26; 95% CI: 2.52-9.80), independent of potential confounders.

CONCLUSIONS: The study highlights the magnitude of the risk of MS for AMI in Mexican young adults. The phenomenon of coronary diseases among young adults needs essential attention from the health sector.
