Prospective Comparison of Metolazone Versus Chlorothiazide for Acute Decompensated Heart Failure With Diuretic Resistance

Stopped early · Phase 4

Conditions studied: Heart Failure, Heart Failure With Reduced Ejection Fraction, Heart Failure Acute, Cardiovascular Diseases

In brief

The primary objective of the study is to compare efficacy of metolazone and chlorothiazide as add-on therapy in patients refractory to loop diuretics with heart failure with a reduced ejection fraction (HFrEF). This will be a single-center randomized pilot study.
