Overview
Brief Summary
Heart Failure with preserved Ejection Fraction (HFPEF) accounts for 40-50% of all heart failure patients with a frequency of hospital admissions for acute decompensation and short and long term mortality similar to patients with heart failure with reduced ejection fraction (HFREF). Patients with HFPEF are often preload dependent and despite admission to the hospital for acute decompensated heart failure (ADHF), are typically difficult to diurese due to the development of acute kidney injury. No studies have been performed evaluating treatment strategies for these patients. The investigators hypothesize that changing the method of diuresis and/or the addition of low-dose dopamine for the treatment of ADHF in patients with HFPEF will reduce renal injury, resulting in a shorter length of stay, and decrease hospital readmissions over the ensuing year. This trial will randomize patients to either bolus or continuous infusion furosemide and then to either dopamine or no dopamine. The primary endpoint will be renal function at 72 hours as measured by change in Glomerular Filtration Rate (GFR). Secondary endpoints for readmission, functional capacity, quality of life, and amount of diuresis will also be collected.

Arms & Interventions
Bolus furosemide and no dopamine
If the patient is not on a prior diuretic dose, a standard dose of furosemide 40mg IV every 12 hrs, with total dose of 80 mg IV over 24 hrs will be initiated. If the patient is already on a prescribed diuretic dose, their outpatient dose will be doubled and administered as the equivalent IV dose every 12 hrs. (i.e if the prescribed dose is furosemide 80mg by mouth twice daily, the inpatient treatment dose will be furosemide 80mg IV twice daily).
Intervention: Furosemide
Continuous infusion furosemide and no dopamine
If the patient is not on a prior diuretic dose, a standard dose of furosemide 80mg IV over 24 hrs, will be initiated. If the patient is already on a prescribed diuretic dose, their outpatient dose will be doubled and administered as the equivalent IV dose continuously over 24 hrs. . (i.e. if the prescribed dose is furosemide 80mg by mouth twice daily, the inpatient treatment dose would be furosemide 160mg IV to be administered continuously over 24 hrs).
Intervention: Furosemide
Bolus furosemide plus dopamine
Intermittent furosemide diuretic therapy as outlined with the addition of dopamine at 3 µg/kg/min
