Early diuretic strategies and the association with In-hospital and Post-discharge outcomes in acute heart failure.

Journal Article (Journal Article)

BACKGROUND: Decongestion is a primary goal during hospitalizations for decompensated heart failure (HF). However, data surrounding the preferred route and strategy of diuretic administration are limited with varying results in prior studies. METHODS: This is a retrospective analysis using patients from ASCEND-HF with a stable diuretic strategy in the first 24 hours following randomization. Patients were divided into three groups: intravenous (IV) continuous, IV bolus and oral strategy. Baseline characteristics, in-hospital outcomes, 30-day composite cardiovascular mortality or HF rehospitalization and 180-day all-cause mortality were compared across groups. Inverse propensity weighted modeling was used for adjustment. RESULTS: Among 5,738 patients with a stable diuretic regimen in the first 24 hours (80% of overall ASCEND trial), 3,944 (68.7%) patients received IV intermittent bolus administration of diuretics, 799 (13.9%) patients received IV continuous therapy and 995 (17.3%) patients with oral administration. Patients in the IV continuous group had a higher baseline creatinine (IV continuous 1.4 [1.1-1.7]; intermittent bolus 1.2 [1.0-1.6]; oral 1.2 [1.0-1.4] mg/dL; P <0.001) and high NTproBNP (IV continuous 5,216 [2,599-11,603]; intermittent bolus 4,944 [2,339-9,970]; oral 3,344 [1,570-7,077] pg/mL; P <0.001). There was no difference between IV continuous and intermittent bolus group in weight change, total urine output and change in renal function till 10 days/discharge (adjusted P >0.05 for all). There was no difference in 30 day mortality and HF readmission (adjusted OR 1.08 [95%CI: 0.74, 1.57]; P = 0.701) and 180 days mortality (adjusted OR 1.04 [95%CI: 0.75, 1.43]; P = 0.832). CONCLUSION: In a large cohort of patients with decompensated HF, there were no significant differences in diuretic-related in-hospital, or post-discharge outcomes between IV continuous and intermittent bolus administration. Tailoring appropriate diuretic strategy to different states of acute HF and congestion phenotypes needs to be further investigated.
