Abstract

Background: Population-based cohort studies demonstrate that metabolic syndrome (MeS) is associated with increased risk for cardiovascular diseases and related mortalities. The present study was designed to investigate the prognostic impact of MeS in patients with acute myocardial infarction (AMI). Methods and Results: The study group was 461 AMI patients without a history of previous myocardial infarction. On the basis of the National Cholesterol Education Program Adult Treatment Panel III criteria, MeS was defined having at least 3 of the following 5 conditions: dysglycemia (impaired fasting glucose, current use of insulin or oral hypoglycemic drugs), hypertriglyceridemia, low high-density lipoprotein-cholesterol level, hypertension and obesity. The prevalence of MeS was 37% (n=172). C-reactive protein (CRP) levels increased with the increase in the number of conditions of MeS. During follow-up at a median of 17.6 months, the incidence of major adverse cardiovascular events (MACE) was significantly different between patients with and without MeS. Furthermore, after adjustment of predictive factors (age, sex, Killip class, multivessel coronary artery disease, low ejection fraction and high CRP level), MeS was an independent risk factor for MACE. Conclusions: In patients with AMI, MeS is associated with systemic inflammation and is an important predictor for MACE, which suggests the need for early identification and medical intervention for secondary prevention of MeS.
