Effects of ACE Inhibitors, Angiotensin Receptor Blockers and Angiotensin Receptor-Neprilysin Inhibitors on Survival Free from Gastrointestinal Bleeding in HeartMate 3 Patients - A Marginal Structural Modeling Analysis

The HeartMate 3 (HM3) is superior to HMII in survival free from disabling stroke and pump exchange, however, rates of GIB remain high. Prior studies show a protective effect of digoxin and ACEi/ARB on risk for GIB, whereas phosphodiesterase 5 inhibitors (PDE5i) have opposite effect in HMII using Cox Proportional Hazard (PH) models with inverse probability weighting (IPW). Compared to this approach, marginal structural modeling (MSM) accounts for time-dependent confounding thereby producing results closer to true causal effect.
