RENO-DEFEND 1的设计原理和结果：一项在急性心力衰竭住院患者中探索选择性A1腺苷拮抗剂SLV320剂量的随机研究

Background

Baseline renal impairment as well as worsening renal function during hospitalization is associated with worse short- and long-term outcomes in patients hospitalized for acute heart failure (AHF). We hypothesized that selective A1 adenosine receptor blockade would induce natriuresis while preserving renal function in AHF patients with renal dysfunction.

Methods

A phase II, randomized, double-blind, placebo-controlled, parallel group, multicenter study to evaluate the efficacy and safety of 2.5, 7.5, 15, and 30 mg/d SLV320 (1 hour intravenous infusions of 1.25, 3.75, 7.5, and 15 mg SLV320, every 12 hours for 3 days [a total of 6 doses] in addition to standard therapy) in subjects hospi
