Abstract

Background: Phosphodiesterase-5 inhibitors (PDE5i) have been used to treat pulmonary hypertension and right ventricular failure in patients with left ventricular assist devices (LVAD). The effects of PDE5i on post-LVAD outcomes including hemocompatibility-related adverse events are not well-established. This systematic review and meta-analysis aims to evaluate the effects of PDE5i on post-LVAD outcomes. Methods and Results: A comprehensive literature search was conducted using Pubmed and Embase databases from inception through November 25, 2020, to compare post-LVAD outcomes in patients with or without PDE5i use. Pooled odds ratio (OR) with 95% confidence intervals (CI) and I2 statistic were calculated. Thirteen observational studies were included in this analysis. The use of PDE5i was not significantly associated with lower postoperative right ventricular failure (OR 0.38, 95% CI 0.02–5.96, P = .41). There was no significant association between PDE5i and gastrointestinal bleeding (OR 1.23, 95% CI 0.76–1.98, P = .2), overall stroke (OR 0.60, 95% CI 0.21–1.68, P = .17), ischemic stroke (OR 0.61, 95% CI 0.09–4.07, P = .38), or pump thrombosis (OR 0.71, 95% CI 0.14–3.54, P = .46). Conclusions: Our meta-analysis showed no significant association between PDE5i and post-LVAD right ventricular failure. Despite the antiplatelet effects of PDE5i, there was no significant association between PDE5i and gastrointestinal bleeding, overall stroke, ischemic stroke, or pump thrombosis. Randomized controlled studies are warranted to evaluate the net benefits or harms of PDE5i in the LVAD population.
