Elements of the protocol included reduced intraoperative corticosteroids (from methylprednisolone 1000 to 250 mg), conversion of steroid taper to be administered once-daily instead of BID, optimal end-of-case intraoperative extubation, multimodal analgesia, early removal of surgical drains, implementation of dietary and physical therapy plans and education for multidisciplinary providers and patients about expected LOS. The primary outcome was post-LT LOS. Secondary outcomes included incidence of delirium, ICU LOS, rejection at 60 days and readmission within 30 days of discharge. A total of 125 LTRs were included.

However, DCD organs experience long-term damage caused by warm ischemia (WI) and microthrombosis caused by diffuse intravascular coagulation. Unfortunately, because of concerns about post-transplantation complications, most organs considered high-risk are discarded, resulting in wasted medical resources and economic losses. However, thrombolytic therapy before transplantation may dissolve microthrombosis in DCD organs, improve organ microcirculation, and increase organ use.

Overall, the role of thrombolytic therapy should not be overlooked.

KPS trajectory during the waitlist period and the first year posttransplant predicted survival, independent of baseline KPS. Decrease in KPS &gt; −30% and −30% to &lt; 0% in the first year were associated with 5.74 (3.45–9.56) and 2.09 (1.69–2.59) times higher mortality than stable KPS after adjusting for baseline KPS and other factors. Poor KPS trajectory in the waitlist period was similarly associated with higher mortality.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>Functional status improvement is an important outcome following heart transplantation, and KPS trajectory predicts survival. Most patients achieve high KPS, but clinical and social interventions may optimize KPS trajectory for high-risk patients.</p>\u0000 </section>\u0000 </div>","PeriodicalId":10467,"journal":{"name":"Clinical Transplantation","volume":"39 2","pages":""},"PeriodicalIF":1.9,"publicationDate":"2025-02-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362967","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
