JACC:九旬老人的经股动脉TAVR

2019-05-22 xiangting MedSci原创

尽管基线合并症的患病率较低,但九旬老人经股动脉TAVR后的死亡率比90岁以下患者高2倍。此外,九旬老人院内卒中、严重或危及生命的出血和新发房颤的风险较高。

这项研究旨在比较接受经导管主动脉瓣置换术(TAVR)九旬老人与90岁以下患者的患者特征和临床结局差异,并检验logistic EuroSCORE(欧洲心脏手术风险评估系统)、EuroSCORE II和STS-PROM(胸外科医师学会预测死亡风险)预测九旬老人TAVR后死亡率的准确性。

由于预期寿命延长,严重主动脉瓣狭窄的患病率正在升高。然而,评估90岁以上患者结局的数据有限。此外,尚未在经股动脉TAVR的九旬老人中评估过死亡风险评分的预测准确性。

CENTER(经导管主动脉瓣植入患者的脑血管事件)合作(N=12,381)是一项国际合作研究,包括3个全国性登记、6个地方或多中心登记和1项前瞻性临床研究,通过系统性在线检索进行选择。研究的主要终点是九旬老人与90岁以下患者TAVR后30天全因死亡率和卒中的差异。次要终点包括基线特征、院内结局的差异,以及logistic  EuroSCORE、EuroSCORE II和STS-PROM预测准确性的差异。

纳入2007年至2018年接受经股动脉TAVR的882名九旬老人和11,499名90岁以下患者。九旬老人的合并症明显较少。然而,九旬老人的30天死亡率(9.9%vs.5.4%;相对风险[RR]:1.8;95%置信区间[CI]:1.4至2.3;p=0.001)、院内卒中率(3.0%vs.1.9%;RR:1.5;95%CI:1.0至2.3;p=0.04)、严重或危及生命的出血率(8.1%vs.5.5%;RR:1.6; 95%CI:1.1至2.2;p=0.004)和新发房颤更高(7.9%vs.5.2%;RR:1.6;95%CI:1.1至2.2;p=0.01)。STS-PROM准确预测了九旬老人的死亡率,观察-预期死亡率比值为1.0。

在这项大规模、全球性、患者水平分析中,尽管基线合并症的患病率较低,但九旬老人经股动脉TAVR后的死亡率比90岁以下患者高2倍。此外,九旬老人院内卒中、严重或危及生命的出血和新发房颤的风险较高。STS-PROM是唯一能够准确预测九旬老人死亡风险的手术风险评分。
