Predictive value of metabolic syndrome definitions in patients with myocardial infarction with ST segment elevation – are they all the same?

AbstractObjectives: We sought to determine the predictive power of metabolic syndrome (MS) definitions on the prognosis in patients with myocardial infarction with ST-segment elevation (STEMI).Methods: We prospectively included 507 patients with STEMI who were admitted for primary percutaneous coronary intervention and could be identified for MS using the AHA-NHLBI, NCEP-ATP III and IDF definitions. After applying these criteria, we divided the group in patients with MS and without MS; we compared baseline characteristics, clinical findings and outcomes among these patients.Results: The prevalence of MS was lowest with the NCEP-ATP III definition (37.87%), followed by the AHA-NHLBI definition (42.80%) and highest when using the IDF definition (44.38%). During follow-up, the occurrence of new myocardial infarction and new revascularization was significantly higher in patients with MS. Only in a group of patients with MS according to the NCEP-ATP III definition, a higher number of strokes were recorded. Mul...
