Study Details

Study Description

Brief Summary

The purpose of the study is to evaluate how well tolerated and effective an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) is in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to usual care oral vasodilator therapy.

Detailed Description

The aim of this pilot study is to prospectively determine the short-term (at 3 months) and long-term (at 6 and 12 months) safety and efficacy of an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to standard-of-care (usual care) oral vasodilator therapy.

Arms and Interventions

Arm	Intervention/Treatment
Experimental: Sacubitril-valsartan study arm Start medication-naïve patients on low-dose sacubitril-valsartan (24/26 mg PO BID) without a washout period per guideline and label recommendations. Switch patients to equivalent dose sacubitril-valsartan if on prior ACE inhibitor (after a 36 hour washout period) or ARB therapy (after discontinuing one day prior). If therapeutic range MAP (65 to 85 mm Hg), discontinue other oral vasodilator (e.g., hydralazine, isordil) or non-rate limiting dihydropyridine calcium channel blocker (non-DHP CCB, e.g., amlodipine) therapy on the day prior to sacubitril-valsartan initiation. If MAP > 85 mm Hg, low-dose sacubitril-valsartan will be added with or without discontinuation of other oral vasodilator or non-DHP CCB per physician's discretion based on drug tolerability and maintenance of therapeutic range MAP. Sacubitril-valsartan can be up-titrated every 2-4 weeks per standard practice guidelines per physician's discretion as above.
