Objective: To examine the association of serum γ-glutamyltransferase (GGT) with incident heart failure. Methods and Results: We related serum GGT to the incidence of heart failure in 3544 (mean age, 44.5 years; 1833 women and 1711 men) Framingham Study participants who were free of heart failure and myocardial infarction. On follow-up (mean, 23.6 years), 188 participants (77 women) developed new-onset heart failure. In multivariable Cox proportional hazards regression models adjusting for standard risk factors and alcohol consumption as time-varying covariates (updated every 4 years), each SD increase in log-GGT was associated with a 1.39-fold risk of heart failure (95% CI, 1.20 to 1.62). The linearity of the association was confirmed by multivariable- adjusted splines, and the relations remained robust on additional adjustment for hepatic aminotransferases and C-reactive protein. Participants with a serum GGT level at the median or greater had a 1.71-fold risk of heart failure (95% CI, 1.21 to 2.41) compared with individuals with GGT concentrations less than the median. GGT marginally increased the model C-statistic from 0.85 to 0.86 but improved the risk reclassification modestly (net reclassification index, 5.7%; P=0.01). Conclusion: In this prospective study of a large community-based sample, higher serum GGT concentrations within the "normal" range were associated with greater risk of heart failure and incrementally improved prediction of heart failure risk.
