Advanced HF was an independent predictor of 2-year all-cause death (adjusted HR 1.52, 95% CI 1.09-2.10). Optimal M-TEER, as compared to a no-optimal M-TEER, was associated with a reduced risk of death both in patients with advanced (HR 0.55, 95% CI 0.32-0.97; p = 0.039) and no-advanced HF (HR 0.59, 95% CI 0.46-0.78; p < 0.001; p = 0.778 for interaction).</p><p><strong>Conclusions: </strong>Advanced HF is associated with poor outcome in patients undergoing M-TEER. However, an optimal SMR reduction reduces the risk of 2-year mortality regardless of HF severity.</p>","PeriodicalId":10474,"journal":{"name":"Clinical Research in Cardiology","volume":" ","pages":"836-845"},"PeriodicalIF":3.8,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12202617/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141751312","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
