This narrative review evaluates the limitations of current heart transplantation allocation models, which prioritize medical urgency and waitlist time but fail to adequately predict long-term post-transplant outcomes. It aims to identify advanced metrics that can strengthen the prioritization framework while addressing persistent racial, geographic, and socioeconomic inequities in access to transplantation.
Recent research indicates that incorporating frailty, nutritional status, immunological compatibility, and pulmonary hemodynamics into allocation frameworks can enhance the prediction of transplant outcomes. The growing use of mechanical circulatory support (MCS) as a bridge to transplantation provides stabilization for critically ill patients; however, disparities in access persist. Studies continue to emphasize the barriers faced by minority and pediatric populations, highlighting the need for expanded donor networks and improved matching criteria. This review highlights the necessity of shifting transplantation prioritization toward multidimensional candidate evaluations that consider both clinical complexity and long-term outcomes. Policy reforms aimed at addressing healthcare disparities and optimizing donor utilization are crucial for improving patient outcomes. Future research should focus on assessing the effectiveness of advanced allocation models, such as continuous distribution frameworks, to promote equitable and sustainable transplantation systems.
本叙述性综述评估了当前心脏移植分配模型的局限性,这些模型优先考虑医疗紧迫性和等待名单时间,但未能充分预测移植后的长期结果。其目的是确定先进的指标,这些指标可以加强优先排序框架,同时解决在获得移植机会方面持续存在的种族、地理和社会经济不平等问题。
最近的研究表明,将虚弱程度、营养状况、免疫相容性和肺血流动力学纳入分配框架可以提高对移植结果的预测。越来越多地使用机械循环支持(MCS)作为移植桥梁,为重症患者提供了稳定;然而,在获得治疗机会方面的差距仍然存在。研究继续强调少数族裔和儿科人群面临的障碍,突出了扩大供体网络和改进匹配标准的必要性。本综述强调了将移植优先排序转向考虑临床复杂性和长期结果的多维度候选评估的必要性。旨在解决医疗保健差距和优化供体利用的政策改革对于改善患者结果至关重要。未来的研究应侧重于评估先进分配模型(如连续分配框架)的有效性,以促进公平和可持续的移植系统。
