P1825R2CHADS score - better than CHA2DS2-VASc as a predictor of mortality in the patients with heart failure

Introduction: CHA2DS2-VASc and R2CHADS scores were developed for the cardioembolic risk evaluation of the patients with atrial fibrillation (AF). Recently, CHA2DS2-VASc score was proposed as a predictor of cardiovascular events and mortality in these patients. Our objective is to compare the utility of these two scores as predictors of mortality in the heart failure patients with or without AF. Methods: We retrospectively included the patients with age >18 years with diagnosis of heart failure with reduced or preserved left ventricular ejection fraction (LVEF) consecutively hospitalized in our clinic between January 1st 2011 and December 31st 2014. We excluded the patients deceased during hospitalization, with pulmonary embolism or acute coronary syndrome and pregnant women. The mortality was evaluated in January 2017, the survival being analyzed over a period of 46±5 months. Results: Our study included 805 patients of which 54.4% were female and 38.1% had AF. The median CHA2DS2-VASc was 4 (2; 6), and R2CHADS 3 (1; 8). The mortality rate was 35.1%.
