A Narrative Review on the Efficacy and Safety of Loop Diuretics in Patients With Heart Failure With Reduced Ejection Fraction and Preserved Ejection Fraction.

In clinical practice, loop diuretics have also been utilized for patients with chronic HF with reduced and preserved ejection fractions. There is a paucity of quality evidence of the effect of loop diuretics use and dosing on clinical outcomes in HF patients beyond symptomatic relief.
