                gurgitation,AFMR)患者,行外科二尖瓣成形联合房颤消融术与规范化内科药物治疗的临床效果及远期预后。方法:本研究为
                回顾性队列研究。连续纳入2019年1月—2024年12月于南京医科大学第一附属医院及伊犁州友谊医院住院治疗的70岁以
                上 AFMR 合并持续性房颤患者。根据治疗策略分为外科组(二尖瓣成形+房颤消融+左心耳处理)和内科组(规范化药物治
                疗)。应用倾向性评分匹配(propensity score matching,PSM)按1∶1比例平衡两组基线特征,最终每组纳入91例患者。主要终点为
                全因死亡率,次要终点包括缺血性脑卒中、房颤复发、心力衰竭再入院率及二尖瓣反流复发。结果:91对匹配患者中位随访时间为
                41.5(26.4,47.0)个月。随访期间共观察到46例死亡。外科组与内科组的5年生存率分别为61.9%和61.4%,Log⁃Rank检验显示两
                组总体生存分布差异无统计学意义(P=0.788)。与内科组相比,外科组显著降低了缺血性脑卒中发生率(5.5% vs. 18.7%,P=
                0.012)及中重度二尖瓣反流发生率(28.6% vs. 100.0%,P < 0.001)。外科组随访期间房颤复发率显著低于内科组(78.0% vs.
                100.0%,P=0.002)。两组间脑出血及心力衰竭再住院率差异无统计学意义(均P > 0.05)。结论:对于高龄AFMR 合并房颤患
                者,外科手术虽未能显著延长总生存期,但在纠正瓣膜病变、预防致残性脑卒中方面具有显著优势。临床决策应综合评估患者
                的生理储备与卒中风险,实施个体化治疗。

               [Abstract] Objective:To evaluate the clinical efficacy and long⁃term prognosis of surgical mitral valve repair combined with atrial
                fibrillation(AF)ablation versus standardized medical therapy in elderly patients( ≥70 years)with persistent AF complicated by
                moderate ⁃ to ⁃ severe atrial functional mitral regurgitation(AFMR). Methods:This retrospective cohort study included consecutive
                patients aged ≥70 years with AFMR and persistent AF,admitted to the First Affiliated Hospital of Nanjing Medical University or Yili
                Prefecture Friendship Hospital between January 2019 and December 2024. Patients were divided into two groups according to
                treatment strategy:the surgical group(mitral valve repair+ablation+left atrial appendage closure)and the medical group(standardized
                pharmacotherapy). Propensity score matching(PSM)was performed at a 1∶1 ratio to balance baseline characteristics,resulting in 91
                pairs of patients. The primary endpoint was all⁃cause mortality;secondary endpoints included ischemic stroke,AF recurrence,and
                recurrence of mitral regurgitation. Results:The median follow⁃up for the 91 matched pairs was 41.5(26.4,47.0)months. A total of 46
                deaths occurred during follow⁃up. The 5⁃year survival rates in the surgical and medical groups were 61.9% and 61.4%,respectively,
