No large-scale randomized, placebo-controlled trials evaluate furosemide's effect on mortality and long-term morbidity in diastolic or systolic dysfunction. In short-term studies, furosemide reduces edema, reduces hospitalizations, and improves exercise capacity in the setting of systolic dysfunction (strength of recommendation [SOR]: B, based upon low-quality randomized controlled trials). Furosemide and other diuretics reduce symptomatic volume overload in diastolic and systolic dysfunction (SOR: C, based on expert opinion)
