Circulation:慢性血栓栓塞性肺动脉高压(CTEPH)患者,手术治疗的长期预后会更好

2016-02-01 崔倩 译 MedSci原创

慢性血栓栓塞肺动脉高压(CTEPH),这是一种罕见的急性肺栓塞并发症,特点是肺大血管纤维血栓阻塞联合小血管病变。它可以通过肺部动脉内膜切除术治愈,不能动手术的病人可以通过药物治疗在临床上改善。一个欧洲注册表在27个中心成立,评估手术和非手术CTEPH患者2种不同的人群长期结果和结果相关性。该研究在24个月内前瞻性的招募了679例新诊断的CTEPH患者,在手术患者(n=404)中,1,2和3年的估计

慢性血栓栓塞性肺动脉高压(CTEPH),是一种罕见的急性肺栓塞并发症,特点是较大肺动脉的血栓栓塞联合小血管病变。它可以通过肺部动脉内膜切除术治愈,不能动手术的病人可以通过药物治疗在临床上改善。一个在27个中心成立的欧洲注册表,评估手术和非手术治疗的CTEPH患者人群长期结果,以及结果的相关因素。

该研究在24个月内前瞻性的招募了679例新诊断的CTEPH患者,在手术患者(n=404)中,1,2和3年的估计生存率分别为93% (95% CI, 90-95), 91% (95% CI, 87-93), 和89% (95% CI, 86-92) ;而非手术患者中(n=275),生存率仅为88% (95% CI, 83-91), 79% (95% CI, 74-83), 和70% (95% CI, 64-76)。在两组患者中,PAH靶向治疗不会显著影响生存率。手术患者和非手术患者的死亡率都与NYHA心功能分级IV(HR 4.16,CI 1.49-11.62,P=0.0065,HR 4.76,CI 1.76-12.88,P=0.0021),右心房压力增加(HR 1.34,CI 0.95-1.90,P=0.0992,HR 1.50,CI 1.20-1.88,P=0.0004),和癌症病史(HR 3.02,CI 1.36-6.69,P=0.0065,HR 2.15,CI 1.18-3.94,P=0.0129)相关。其他相关的死亡率与PAH靶向药物、术后pH值、手术并发症和手术患者的额外的心脏手术,合并症例如冠状动脉疾病、左心衰竭、以及未手术患者的COPD相关。

手术患者的长期预后到现在为止是可以接受的,并且比非手术患者的预后要更好。
