Loop diuretic adjustments in patients with chronic heart failure: Insights from HF-ACTION.

ABSTRACT: BACKGROUND:The relationship between diuretic use or change in diuretic use and outcomes in chronic heart failure (HF) remains poorly defined. We evaluated the association between diuretic use and changes in health status, exercise capacity, and clinical events in a large randomized trial of subjects with HF. METHODS:HF-ACTION randomized 2,331 outpatients with HF and ejection fraction ?35% to aerobic exercise training versus usual care. We grouped patients according to loop diuretic use from baseline through 6?months: continued use, never use, initiated, and discontinued. The association between diuretic use and changes in health status, exercise capacity, and clinical outcomes (all-cause mortality/hospitalization, cardiovascular mortality, and HF hospitalization) through 12?months was assessed using Cox proportional hazards models and generalized linear regression models, respectively. RESULTS:A total of 2,004 (86%) patients had complete data on diuretic use. There was no association between diuretic status and Kansas City Cardiomyopathy Questionnaire, 6-minute walk distance, or peak Vo2 in adjusted analyses (all P?>?.05). A dose increase was associated with decrease in 6-minute walk distance (-4.25 m, SE 1.12 m, P?
