Albumin-to-Globulin Ratio as an Independent Predictor of Mortality in Chronic Heart Failure

AIM: Albumin-to-globulin ratio (AGR) is emerged as a marker of impaired prognosis. We determined the predictive value of AGR in patients with heart failure with reduced ejection fraction (HFrEF). METHODOLOGY: 999 patients with HFrEF were enrolled. Rates of 1-year all-cause mortality were compared between AGR quartiles (Q). Moreover, multivariate survival analysis in Cox's regression model and receiver operating characteristic analyses were performed. RESULTS: 90-day and 1-year mortality was the highest in AGR Q1. AGR was an independent predictor of 90-day and 1-year mortality. Receiver operating characteristic analysis revealed moderate diagnostic value in predicting 90-day (AGR cutoff <1.2) and 1-year (AGR cutoff <1.38) mortality. CONCLUSION: AGR had a good prognostic value and remained an independent predictor of mortality in HFrEF patients.
