ACC 2014:哪些严重二尖瓣返流患者适宜早期手术治疗?

2014-04-01 小田 译 医学论坛网

2014年美国心脏病学会年会(ACC 2014)公布的一项研究表明,在年龄≥50岁的严重二尖瓣返流(MR)但无症状的患者中,与保守治疗相比,早期手术与其心血管死亡和心脏事件长期减少显著相关。研究论文3月30日在线发表于《美国心脏病学杂志》(J Am Coll Cardiol)。 研究共纳入610例严重MR但无症状的序贯患者,前瞻性评估保留的左心室功能。接受早期手术和常规治疗的病例数分别为235例

研究共纳入610例严重MR但无症状的序贯患者,前瞻性评估保留的左心室功能。接受早期手术和常规治疗的病例数分别为235例和375例。推断出207对相匹配队列的倾向性评分。在这些队列中对比两种治疗方法的总体死亡率、心血管死亡、和心脏事件(手术死亡、心脏死亡、重复手术和因心力衰竭紧急入院)。

结果显示,在207对倾向性评分相匹配的队列中,与常规治疗组相比,早期手术组患者的心脏死亡和心脏事件风险均校低,P值分别为0.03和0.002,危险比(HR)分别为0.109和0.216。Cox比例风险模型分析显示,与常规治疗组相比,行早期手术治疗、年龄≥50岁患者心脏事件风险显著较低(HR 0.221,P= 0.002),但在年龄<50岁的患者中并无显著差异(P= 0.20)。
