Study Details

Study Description

Brief Summary

This pilot, feasibility study evaluates the efficacy of sacubitril-valsartan (Entresto) versus usual anti-hypertensive medications in patients with left ventricular assist devices (LVAD). It also measures diurnal blood pressure variations in the context of continuous flow physiology.

Condition or Disease Intervention/Treatment Phase
Phase 4

Detailed Description

Left ventricular assist devices (LVAD) have become a life-saving therapy for patients with ACC/AHA stage D congestive heart failure (CHF). Despite longevity and improved quality of life, LVAD-supported patients are plagued with adverse events, the most debilitating of all is stroke. Ischemic and hemorrhagic strokes have been associated with hypertension (mean arterial pressure, or MAP > 90 mmHg) in addition to out-of-range INR and aspirin doses. Strict blood pressure control has been shown in a recent randomized trial to confer a significant decline in stroke rates of patients implanted with the Heartware LVAD. Patients with poorly controlled hypertension are also at risk for inadequate left-ventricular unloading and worsening CHF due to the exquisite sensitivity to afterload of the continuous flow LVAD.

There are no guidelines for the use of anti-hypertensives in LVAD patients. Most are started on standard CHF therapies, though this practice varies greatly across LVAD centers. The angiotensin receptor blocker-neprilysin inhibitor sacubitril-valsartan (Entresto) is a potent anti-hypertensive mediation that was recently approved by the Food and Drug Administration for the treatment of patients with heart failure and low ejection fraction. We aim to randomly assign patients to receive Entresto or usual anti-hypertensive therapy for blood pressure control, then crossover to the other arm after 30 days. Daily blood pressure measurements will be performed and correlated with LVAD pump flows and waveform analysis.
