The exact mechanism of cardiovascular benefit from SGLT2i continues to be the source of further research. The investigators hypothesize that heart failure patients with LVADs will similarly benefit from the SGLT2i-associated natriuresis and diuresis, which in turn reduces preload. This is further associated with reduced heart failure readmissions and right ventricular failure. Additionally, the animal models indicating reduced cardiac work and remodeling in this population may benefit these patients as one of the goals of LVAD implantation is to reduce cardiac energy expenditure and promote remodeling and recovery in these patients.
This is a prospective, randomized controlled study to assess cardiac benefit of SGLT2i in 40 consecutive patients with heart failure undergoing LVAD implantation. After routine LVAD implantation, patients will be randomized 1:1 to one of two routine care arms: management with an SGLT2i [empagliflozin 10 milligram (mg) daily or dapagliflozin 10 mg daily, based on formulary coverage] or no SGLT2i. The patient's treating physician will be able to override randomization assignment if they determine that the assignment is not in the patient's best interest. SGLT2i management (if applicable) and follow-up care will be dictated by routine care. Data will be collected from the subject's medical record for 6 months.
