Prevalence and impact of metabolic syndrome in patients with multivessel coronary artery disease and acute coronary syndrome.

Abstract Background and aims Metabolic syndrome (MetS) is associated with increased incidence of diabetes and cardiovascular diseases in patients initially free from these diseases. However, its prognostic value in patients with established coronary artery diseases remains controversial. Therefore, we aimed to illustrate the prevalence and investigate the impact of MetS in patients with multivessel coronary artery disease (MVD) and acute coronary syndrome (ACS). Methods and results This was a large registry of consecutive patients with ACS referred to primary percutaneous coronary intervention (PCI) and those with MVD were eligible for this analysis. MetS was defined based on modified Adult Treatment Panel III definition. The primary outcome was major adverse cardiovascular events (MACE), a composite of all-cause death, myocardial infarction and stroke. A total of 2532 patients were included in the current analysis and 993 (39.2%) of them had MetS. The prevalence of MetS increased from 2010 to 2016 (p for trend = 0.005). In patients over 60 years old, the prevalence of MetS decreased with aging (p for trend = 0.002). Female subjects had a higher prevalence than their male counterparts (61.5% verse 32.9% and p  Conclusion MetS was frequently observed in patients with MVD and ACS. Patients with MetS were more likely to be young and female. However, it was not an independent predictor for MACE after primary PCI in those patients.
