Combination of diuretics for acute heart failure: a protocol for a systematic review of randomised clinical trials with network meta-analysis and trial sequential analysis

Abstract

INTRODUCTION: Acute heart failure (AHF) is a critical, costly condition with high mortality rates, affecting millions annually. Despite advances in cardiovascular care, AHF treatment lacks robust evidence. AHF commonly manifests with sudden heart failure symptoms such as pulmonary congestion, and the pathophysiology involves fluid overload. Initial treatment is based on intravenous diuretics typically, but the optimal combination of drugs remains uncertain.

METHODS AND ANALYSIS: We will systematically review randomised controlled trials enrolling patients with AHF and volume overload undergoing in-hospital diuretic treatment. We aim to investigate any diuretic intervention. Our search strategy includes the following databases: Embase, Medline, Latin American and Caribbean Health Sciences Literature, Web of Science and the Cochrane Central Register of Controlled Trials. The primary outcome is all-cause mortality. Secondary outcomes are serious adverse events, hospital readmission and kidney failure. Study results reported at the most extended follow-up will be used for all outcomes. If appropriate, we will conduct meta-analysis, trial sequential analysis and network meta-analysis.

ETHICS AND DISSEMINATION: No ethics approval is required for this study. The results will be published in a peer-reviewed journal in this field.
