Rate of successful decongestion higher with addition of acetazolamide to loop diuretic in patients with acute decompensated heart failure
MONDAY, Aug. 29, 2022 (HealthDay News) — For patients with acute decompensated heart failure, the addition of acetazolamide to loop diuretic therapy yields an increased incidence of successful decongestion, according to a study published online Aug. 27 in the New England Journal of Medicine to coincide with the European Society of Cardiology Congress 2022, held from Aug. 26 to 29 in Barcelona, Spain.
Wilfried Mullens, M.D., Ph.D., from Ziekenhuis Oost-Limburg in Genk, Belgium, and colleagues conducted a parallel-group, double-blind, randomized, placebo-controlled trial involving patients with acute decompensated heart failure, clinical signs of volume overload, and an N-terminal pro-B-type natriuretic peptide level of more than 1,000 pg/mL or a B-type natriuretic peptide level of more than 250 pg/mL. Five hundred nineteen participants were randomly assigned to intravenous acetazolamide or placebo added to standard loop diuretics.
The researchers found that successful decongestion occurred in 42.2 percent of 256 patients in the acetazolamide group and in 30.5 percent of 259 patients in the placebo group (risk ratio, 1.46; 95 percent confidence interval, 1.17 to 1.82; P
“These data suggest the use of acetazolamide as a reasonable adjunct to achieving more rapid decongestion,” writes the author of an accompanying editorial.
