Abstrakt: γ-Glutamyl transferase (GGT) participates in oxidative and inflammatory reactions inside the atheroma plaque and platelets. We evaluated whether platelet membrane γ-glutamyl transferase (Plt-GGT) activity is a predictor of major adverse cardiac events (MACEs) during 3 months follow-up of patients with acute coronary syndrome (ACS; MACE-3M). We included 105 patients who were hospitalized consecutively with the diagnosis of ACS. Patients with an MACE-3M were older, more likely to have hypertension, hyperlipidemia, family history of coronary artery disease(CAD), thrombolysis in myocardial infarction (TIMI) risk score >4, higher Plt-GGT and serum GGT activities, serum C-reactive protein level, and lower left ventricular ejection fraction (LVEF) when compared to those without MACE-3M (all P values ≤.05). By receiver–operator characteristic (ROC) curve analysis, 265 mU/mg for Plt-GGT, 30 U/L for serum GGT, and 45% for LVEF were determined as cutoff values to discriminate MACEs. Platelet GGT activity >265 mU/mg, TIMI risk score >4, and family history of CAD were independent predictors of MACE-3M (all P values <.05). Platelet GGT activity was as an independent predictor for MACEs in patients with ACS during the 3 months follow-up. [ABSTRACT FROM AUTHOR]
