A, The ROC curves for CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems in predicting 1-year all-cause mortality in SHF patients. Based on AUCs for predicting all-cause mortality in SHF patients, CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems had c-indices of 0.5595, 0.5898, and 0.6091, respectively (DeLong test, P < .0001). AUC = area under the curve, CHADS2 = congestive heart failure, hypertension, age, diabetes, stroke (doubled), CHA2DS2-VASc = congestive heart failure, hypertension, age ≥ 75 (doubled), diabetes, stroke (doubled), vascular disease, age 65–74, and sex category (female), R2CHADS2 = renal dysfunction (doubled), congestive heart failure, hypertension, age, diabetes, stroke (doubled), ROC = receiver operating characteristic, SHF = systolic heart failure. B, The ROC curves of CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems for predicting 1-year all-cause mortality in SHF patients with AF. Based on AUCs for predicting all-cause mortality in SHF patients with AF, the CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems had c-indices of 0.5878, 0.6055, and 0.6267, respectively (DeLong test, P = .1436). AUC = area under the curve, CHADS2 = congestive heart failure, hypertension, age, diabetes, stroke (doubled), CHA2DS2-VASc = congestive heart failure, hypertension, age ≥ 75 (doubled), diabetes, stroke (doubled), vascular disease, age 65–74, and sex category (female), R2CHADS2 = renal dysfunction (doubled), congestive heart failure, hypertension, age, diabetes, stroke (doubled), ROC = receiver operating characteristic, SHF = systolic heart failure. C, The ROC curves for CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems used to predict 1-year all-cause mortality in SHF patients without AF. Based on AUCs for predicting all-cause mortality in SHF patients without AF, the CHADS2, CHA2DS2-VASc, and R2CHADS2 scoring systems had c-indices of 0.5409, 0.5740, and 0.5987, respectively (DeLong test, P = .0003). AUC = area under the curve, CHADS2 = congestive heart failure, hypertension, age, diabetes, stroke (doubled), CHA2DS2-VASc = congestive heart failure, hypertension, age ≥ 75 (doubled), diabetes, stroke (doubled), vascular disease, age 65–74, and sex category (female), R2CHADS2 = renal dysfunction (doubled), congestive heart failure, hypertension, age, diabetes, stroke (doubled), ROC = receiver operating characteristic, SHF = systolic heart failure.
