Background:The prognostic impact of atrial fibrillation (AF) among patients at high risk for heart failure (HF) remains unclear. In addition, there is no risk estimation model for AF development in these patients.Methods and Results:The present study included 5,382 consecutive patients at high risk of HF enrolled in the CHART-2 Study (n=10,219). At enrollment, 1,217 (22.6%) had AF, and were characterized, as compared with non-AF patients, by higher age, lower estimated glomerular filtration rate, higher B-type natriuretic peptide (BNP) level and lower left ventricular ejection fraction. A total of 116 non-AF patients (2.8%) newly developed AF (new AF) during the median 3.1-year follow-up. AF at enrollment was associated with worse prognosis for both all-cause death and HF hospitalization (adjusted hazard ratio (aHR) 1.31, P=0.027 and aHR 1.74, P=0.001, for all-cause death and HF hospitalization, respectively) and new AF was associated with HF hospitalization (aHR 4.54, P<0.001). We developed a risk score with higher age, smoking, pulse pressure, lower eGFR, higher BNP, aortic valvular regurgitation, LV hypertrophy, and left atrial and ventricular dilatation on echocardiography, which effectively stratified the risk of AF development with excellent accuracy (AUC 0.76).Conclusions:These results indicated that AF is associated with worse prognosis in patients at high risk of HF, and our new risk score may be useful to identify patients at high risk for AF onset.

Background:The prognostic impact of new-onset atrial fibrillation (AF) is not fully elucidated.Methods and Results:We examined 4,818 consecutive stage C/D chronic heart failure (CHF) patients in the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 (CHART-2) Study (n=10,219). At enrollment, 1,859 (38.6%) of them had AF. Compared with the 2,953 patients without AF, AF patients were characterized by higher age (71 vs. 68 years), lower estimated glomerular filtration rate (58.9 vs. 61.9 ml/min/1.73 m2), higher brain natriuretic peptide (152 vs. 74.5 pg/ml), similar left ventricular ejection fraction (56.8 vs. 56.5%), and a similar prescription rate of β-blockers (48.1 vs. 50.6%) and renin-angiotensin system (RAS) inhibitors (72.9 vs. 71.6%). Among the patients without AF at enrollment, 106 (3.6%) developed new AF during the median 3.2-year follow-up, which was associated with increased mortality (adjusted hazard ratio, 1.72; P=0.013). In contrast, neither paroxysmal nor chronic AF at enrollment was associated with increased mortality. The mortality rate was significantly high in the first year after the onset of new AF. On inverse probability of treatment weighting analysis using propensity score, RAS inhibitors and statins were associated with reduced incidence of new AF, and diuretics were associated with increase of new AF.Conclusions:Onset of new AF, but not a history of AF, is associated with increased mortality in CHF patients, especially in the first year.
