Use of Low-Dose Dopamine in Heart Failure with Preserved Ejection Fraction Patients with Right Ventricular Dysfunction

IntroductionHeart failure with preserved ejection fraction (HFpEF) constitutes half of HF hospitalizations in the U.S. Right ventricular dysfunction (RVD) is associated with high morbidity and mortality in HFpEF and serves as an important therapeutic target. The use of low-dose dopamine (DA) has not shown benefit in the treatment of decompensated HF patients; however, the effect of DA on HFpEF patients with RVD (HFpEF-RVD) is unknown.MethodsWe...
