Abstract 17683: LCZ696 vs. ACEI/ARB for Hypertension: A Meta-analysis of Randomized Controlled Trials
Introduction: LCZ696 is a first-in-class inhibitor of the angiotensin II receptor and Neprilysin. The use of LCZ696 in Heart Failure is promising compared to ACEI or ARB. The use of LCZ696 for blood pressure has been studied but controversial. We performed a meta-analysis of randomized controlled trials (RCTs) comparing LCZ696 to ACEI/ARB for lowering systolic blood pressure effect.
Objectives: To assess the efficacy of LCZ696 on systolic blood pressure in comparison to angiotensin-converting-enzyme inhibitor (ACEI)/Angiotensin II receptor antagonist (ARB).
Methods: We searched PubMed, Medline, Embase and Cochrane for prospective RCTs that compared LCZ696 versus ACEI or ARB in patients with established diagnosis of essential hypertension. Trials that included patients with essential hypertension with or without heart failure were randomized to either LCZ696 or ACEI or ARB, and that also reported at least one of the studied outcomes were included. Study quality was assessed using the Jadad score. Heterogeneity of the studies was analyzed by Cochran’s Q statistics. Mean differences were calculated using the random effect model.
Results: Three RCTs met our inclusion criteria and included 8996 patients who had mild-moderate essential hypertension and were between18-75 years. They were randomized to LCZ696 versus ACEI or ARB. The use of LCZ696 was associated with improved systolic blood pressure control when compared to the control group (MD -3.89; 95% CI -7.75, -0.04; P=0.05).
Conclusions: Our findings suggest that the use of LCZ696 in hypertensive patients provides better reduction of blood pressure when compared to an ACEI or an ARB.
