Abstract:
A considerable proportion of candidates for transcatheter aortic valve implantation (TAVI) have underlying heart failure (HF) with preserved ejection fraction (HFpEF), which can be challenging for diagnosis because significant valvular heart disease should be excluded before diagnosing HFpEF. This study investigated the long‐term prognostic value of the pre‐procedural H 2 FPEF score in patients with preserved ejection fraction (EF) undergoing TAVI. Methods and results Patients who underwent TAVI between October 2013 and May 2017 were enrolled from the Optimized CathEter vAlvular iNtervention–Transcatheter Aortic Valve Implantation Japanese multicentre registry. After excluding 914 patients, 1674 patients with preserved EF ≥ 50% (median age: 85 years, 72% female) were selected for calculation of the H 2 FPEF score and were dichotomized into two groups: the low H 2 FPEF score [0–5 points; n = 1399 (83.6%)] group and the high H 2 FPEF score [6–9 points; n = 275 (16.4%)] group. Patients with high H 2 FPEF scores were associated with a higher prevalence of New York Heart Association Functional Class III/IV (59.3% vs. 43.7%, P 〈 0.001), diabetes (24.4% vs. 18.5%, P = 0.03), and paradoxical low‐flow, low‐gradient aortic stenosis (15.9% vs. 6.2%, P 〈 0.001). These patients showed worse prognoses than those with low H 2 FPEF scores regarding the cumulative 2 year all‐cause mortality (26.3% vs. 15.5%, log‐rank P 〈 0.001), cardiovascular mortality (10.5% vs. 5.4%, log‐rank P 〈 0.001), HF hospitalization (16.2% vs. 6.7%, log‐rank P 〈 0.001), and the composite endpoint of cardiovascular mortality and HF hospitalization (23.8% vs. 10.8%, log‐rank P 〈 0.001). After adjustment for several confounders, the high H 2 FPEF scores were independently associated with increased risk for all‐cause mortality [adjusted hazard ratio (HR), 1.48; 95% confidence interval (CI), 1.09–2.00; P = 0.011] and for the composite endpoint of cardiovascular mortality and HF hospitalization (adjusted HR, 1.95; 95% CI, 1.38–2.74; P 〈 0.001). Subgroup analysis confirmed the excess risk of high H 2 FPEF scores relative to low H 2 FPEF scores for the composite endpoint of cardiovascular mortality and HF hospitalization increased with a lower Society of Thoracic Surgeons (STS) score (STS score 〈 8%: adjusted HR, 2.40; 95% CI, 1.50–3.85; P 〈 0.001; STS score ≥8%: adjusted HR, 1.34; 95% CI, 0.79–2.28; P = 0.28; P interaction = 0.030). Conclusions The H 2 FPEF score is useful for predicting long‐term adverse outcomes after TAVI, including all‐cause mortality, cardiovascular mortality, and HF hospitalization for patients with preserved EF. More aggressive interventions targeting HFpEF in addition to the TAVI procedure might be relevant in patients with high H 2 FPEF scores, particularly in those with a lower surgical risk.
