Usefulness of admission gamma-glutamyltransferase level for predicting new-onset heart failure in patients with acute coronary syndrome with left ventricular systolic dysfunction

Our aim was to determine whether there is a relationship between admission gamma-glutamyltransferase (GGT) and subsequent heart failure hospitalizations in patients with acute coronary syndrome. We selected 123 patients with newly diagnosed acute coronary syndrome of ejection fraction (EF) <45%....

Description
Summary:	Our aim was to determine whether there is a relationship between admission gamma-glutamyltransferase (GGT) and subsequent heart failure hospitalizations in patients with acute coronary syndrome. We selected 123 patients with newly diagnosed acute coronary syndrome of ejection fraction (EF) <45%. Patients were followed 15±10 months, and the relationship between admission GGT level and hospitalization because of heart failure during the follow-up was examined. Twenty-three (18.7%) patients were hospitalized during the follow-up of 15±10 months. Receiver operating characteristic (ROC) curve analysis showed that the cut-off point of admission GGT related to predict hospitalization was 49 IU/L, with a sensitivity of 81.7% and specificity of 65.2%. Increased GGT >49 IU/L on admission, presence of hypertension and hyperlipidemia, left ventricular ejection fraction (LVEF), right ventricular dysfunction, moderate-to-severe mitral regurgitation, alanine aminotransferase level, and antiplatelet agent usage were found to have prognostic significance in univariate Cox proportional hazards analysis. In multivariate Cox proportional-hazards model, increased GGT >49 IU/L on admission (hazard ratio [HR] 2.663, p=0.047), presence of hypertension (HR 4.107, p=0.007), and LVEF (HR 0.911, p=0.002) were found to be independent factors to predict new-onset heart failure requiring hospitalization. Hospitalization in heart failure was associated with increased admission GGT levels. Increased admission GGT level in acute coronary syndrome with heart failure should be monitored closely and treated aggressively.
