The importance of two metabolic syndrome diagnostic criteria and body fat distribution in predicting clinical severity and prognosis of acute myocardial infarction

Introduction: The interrelation between metabolic syndrome (MetS) (the revised National Cholesterol Education Program-Adult Treatment Panel III (NCEP- ATP III) and International Diabetes Federation (IDF)) and obesity indices in predicting clinical severity and prognosis of acute ST-elevation myocardial infarction (STEMI) is insufficiently known. Material and methods: This prospective study included 250 acute STEMI patients treated with primary percutaneous coronary intervention. The patients with/without MetS were analyzed by baseline (medical history, demography and obesity indices: overall – body mass index (BMI) vs. central – body adiposity index (BAI), conicity index (Cindex), visceral adiposity index (VAI), waist circumference (WC), waist-to-hip (WHR) and waist-to-height ratio (WHtR)), severity (clinical presentation, laboratory, echocardiography, coronary angiography and in-hospital complications) and prognostic parameters (major adverse cardiovascular events and sick leave duration during 12-month follow-up). Results: There were 136 (54.4%) and 147 (58.8%) patients with MetS (NCEP-ATP III) and MetS (IDF), respectively. MetS (NCEP-ATP III) increased the risk of > 1 significantly stenosed coronary artery (CA), very high BAI increased the risk of dyspnea, Cindex > 1.25/1.18 increased the risk of total in- hospital complications, increased VAI increased the risk of coronary segment 3 significant stenosis, WHR ≥ 0.90/0.85 increased the risk of proximal/middle coronary segments (especially of segment 1) significant stenosis, WHtR ≥ 63/58 increased the risk of heart failure, and the number of significantly stenosed CAs increased the risk of total MACE (p < 0.05). Conclusions: MetS (NCEP-ATP III) and several central obesity indices are superior to BMI in predicting acute STEMI severity (clinical presentation, in-hospital complications, severity of coronary disease), while WC and MetS (IDF) have no influence on it. They all have no influence on prognosis.
