Clinical Application of Guideline-Directed Medical Therapy in TAVR Patients With Heart Failure and Reduced Ejection Fraction

By Kobari Y, Maznyczka A, Khokhar AA et al.

BACKGROUND: There are limited data concerning the impact of heart failure (HF) guideline-directed medical therapy (GDMT) in patients with HF with reduced ejection fraction (HFrEF) who undergo transcatheter aortic valve replacement (TAVR). OBJECTIVES: The aims of this study were to determine whether TAVR patients with HFrEF receive optimal HF-GDMT and to investigate the prognostic significance of HF-GDMT in this setting. METHODS: In a prospective registry, consecutive TAVR patients with HFrEF were stratified into 4 groups (quadruple, triple, double, or single or no therapy) according to prescription of HF-GDMT at discharge post-TAVR and after a 3-month GDMT optimization period. Major adverse cardiovascular events (MACE) were defined as a composite of cardiovascular mortality or hospitalization for heart failure. The median follow-up time was 699 days (Q1-Q3: 510-961 days). RESULTS: Among 336 TAVR patients with HFrEF, the rates of quadruple, triple, double, and single or no HF-GDMT were 15%, 19%, 28%, and 38% at discharge and 27%, 21%, 21%, and 27% at 3 months postprocedure, respectively. Among 280 patients (83.3%) eligible for quadruple HF-GDMT, only 27% (n = 76) received this combination at 3 months post-TAVR. Following a 3-month HF-GDMT optimization period, 2-year MACE rates were lower in patients taking quadruple (15.0%; 95% CI: 5.2%-24.8%) compared with triple (22.6%; 95% CI: 10.4%-34.8%), double (24.2%; 95% CI: 13.8%-34.6%), and single or no therapy (43.6%; 95% CI: 31.8%-55.4%; log-rank P < 0.001). CONCLUSIONS: HF-GDMT is underused in patients with HFrEF who undergo TAVR, and suboptimal HF-GDMT is associated with increased MACE in this setting. Strategies to improve the initiation and up-titration of HF-GDMT in TAVR patients with HFrEF are needed.
