Acute pulmonary pressure change after transition to sacubitril/valsartan in patients with heart failure reduced ejection fraction
Abstract
AIMS: Sacubitril/valsartan combines renin-angiotensin-aldosterone system inhibition with amplification of natriuretic peptides. In addition to well-described effects, natriuretic peptides exert direct effects on pulmonary vasculature. The effect of sacubitril/valsartan on pulmonary artery pressure (PAP) has not been fully defined.
METHODS AND RESULTS: This was a retrospective case-series of PAP changes following transition from angiotensin-converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB) to sacubitril/valsartan in patients with heart failure reduced ejection fraction and a previously implanted CardioMEMS™ sensor. Pre-sacubitril/valsartan and post-sacubitril/valsartan PAPs were compared for each patient by examining averaged consecutive daily pressure readings from 1 to 5 days before and after sacubitril/valsartan exposure. PAP changes were also compared between patients based on elevated trans-pulmonary gradients (trans-pulmonary gradient ≥ 12 mmHg) at time of CardioMEMS™ sensor implantation. The cohort included 18 patients, 72% male, mean age 60.1 ± 13.6 years. There was a significant decrease in PAPs associated with transition from ACEI/ARB to sacubitril/valsartan. The median (interquartile range) pre-treatment and post-treatment change in mean, systolic and diastolic PAPs were -3.6 (-9.8, -0.7) mmHg (P < 0.001), -6.5 (-15.0, -2.0) mmHg (P = 0.001), and -2.5 (-5.7, -0.7) (P = 0.001), respectively. The decrease in PAPs was independent of…
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health. Reported size: 18 participants or records.
