All-cause acute mortality was the primary outcome of interest.</p><p><strong>Results: </strong>A total of 46,141 recipients were included in our analysis. The percentage of obese patients and donors increased over the years, from 21.5 % and 17.2 % in 2000 to 34.4 % and 33.1 % in 2022, respectively. Survival analysis found a stepwise reduction in mortality risk for severely undersized grafts as BMI increased (normal: HR = 1.59, p < 0.001; overweight: HR = 1.20, p = 0.029), until ultimately reaching insignificant levels in obese groups across all PHMR categories.</p><p><strong>Conclusion: </strong>Patients with a normal to overweight BMI were susceptible to increased mortality with a severely undersized graft. Conversely, obese groups appeared to be resistant to the hazards of organ size mismatching by PHMR. The clinical implications of this study may enable recruitment from a larger donor pool and improve challenges in transplantation for obese patients.</p>","PeriodicalId":15223,"journal":{"name":"Journal of cardiology","volume":" ","pages":"172-178"},"PeriodicalIF":2.6,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143390797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
