Afib, Heart Failure, and Exercise
The HF-ACTION (Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training) study evaluated the safety and efficacy of exercise training in heart failure patients with atrial fibrillation. Clinical characteristics and outcomes (mortality/hospitalizations) were assessed by baseline AF status: past history of AF or AF on baseline electrocardiogram vs no AF).

-- n=308 (13%) of patient excluded due to “other” rhythm
-- Overall, mean age was ~59y, 30% female, 60% white, 34% black.
-- All patients >90% use of beta-blockers and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers at baseline.
-- Adjustment for dosage of beta-blocker, KCCQ symptom stability, LVEF, country, sex, ventricular conduction, Weber class, blood urea nitrogen, and mitral regurgitation.
