Abstract

AIMS: Heart failure (HF) and atrial fibrillation (AF) may coexist and influence each other. However, characteristics, anticoagulant treatment, and outcomes of contemporary AF patients with concurrent HF are ill‐defined. This study analyses characteristics, treatment, and 2 year outcomes in newly diagnosed Global Anticoagulant Registry in the FIELD‐Atrial Fibrillation (GARFIELD‐AF) patients with vs. without HF. METHODS AND RESULTS: GARFIELD‐AF is the world's largest observational AF patient study. At enrolment, 11 758 of 52 072 patients (22.6%) had HF; 76.3% were New York Heart Association class II–III. Patients with HF had comparable demographics, blood pressure, and heart rate but more likely had permanent (15.6% vs. 11.9%) or persistent AF (18.9% vs. 13.8%), acute coronary syndromes (16.7% vs. 8.9%), vascular disease (40.8% vs. 20.2%), and moderate‐to‐severe chronic kidney disease (14.6% vs. 9.0%) than those without. Anticoagulant prescription was similar between the two groups. At 2 year follow‐up, patients with HF showed a greater risk of all‐cause mortality [hazard ratio (HR), 2.06; 95% confidence interval (CI), 1.91–2.21; P < 0.0001], cardiovascular mortality (HR, 2.91; 95% CI, 2.58–3.29; P < 0.0001), acute coronary syndromes (HR, 1.25; 95% CI, 1.02–1.52; P = 0.03), and stroke/systemic embolism (HR, 1.24; 95% CI, 1.07–1.43; P = 0.0044). Major bleeding rate was comparable (adjusted HR, 1.00; 95% CI, 0.84–1.18; P = 0.968). Among patients without HF at baseline, incidence of new HF was low [0.69 (95% CI, 0.63–0.75) per 100 person‐years], whereas propensity to develop worsening HF was higher in those with HF [1.62 (95% CI, 1.45–1.80) per 100 person‐years]. CONCLUSIONS: Patients with AF and HF have a high risk of all‐cause and cardiovascular mortality and stroke/systemic embolism and may develop worsening HF.
