Circ Heart Failure:他汀类药物可提高心脏移植者的生存率

2016-11-13 xing.T MedSci原创

合并分析的证据表明他汀类药物可提高心脏移植者的生存率,而且还可以预防致命的排斥反应,减少晚期癌症风险,降低冠状动脉病变的发生率。需要进一步的前瞻性研究,来进一步调查和解释这种相关性。

虽然各种研究结果表明他汀类药物对心脏移植患者具有有益作用,但是这些研究都相对较小和效力较低。近日,心血管领域权威杂志Circ Heart Failure上发表了一篇来自美国俄亥俄州立大学Wexner医疗中心心内科Ajay Vallakati医生及其团队的一项荟萃分析结果,该文章中研究者评估了他汀类药物对心脏移植术后患者的影响,特别是对影响血流动力学的明显/致命排斥反应、冠状动脉血管病变、晚期癌症和总体生存率的影响。

研究者检索了PubMed、Cochran中心和Web of Science 数据库,通过检索“cardiac transplant”或“heart transplant”,以及“statin”等主题词来搜索相关文献。研究人员采用Mantel–Haenszel 法的随机效应模型进行数据合并分析,共确定了10项研究,其中4个为随机对照试验,另外6个为非随机研究,它们比较了心脏移植者接受他汀类药物治疗和未接受他汀类药物治疗的临床预后。有9个研究报告了死亡率的研究合并分析结果,结果显示,他汀类药物的使用与全因死亡率的显著降低相关(比值比为0.26;95%置信区间为0.20–0.35;P<0.0001),他汀类药物也可显著降低影响血流动力学的明显/致命排斥反应的风险(比值比为0.37;95%置信区间为0.21–0.65;P=0.0005)、冠状动脉病变发生率(比值比为0.33;95%置信区间为0.16–0.68;P=0.003)和晚期癌症发生率(比值比为0.30;95%置信区间为0.15–0.63;P=0.002)。

由此可见,合并分析的证据表明他汀类药物可提高心脏移植者的生存率,而且还可以预防致命的排斥反应,减少晚期癌症风险,降低冠状动脉病变的发生率。需要进一步的前瞻性研究,来进一步调查和解释这种相关性。

J Thromb Haemost:他汀类药物可以降低复发性静脉血栓形成风险

根据一项以人群为基础的队列研究的结果,对于既往发生过静脉血栓形成的患者,使用他汀类药物可以降低复发性静脉血栓形成的风险。 华盛顿大学流行病学系教授Nicholas L. Smith博士称:虽然抗凝治疗可有效的预防血栓复发,但长期治疗存在大出血风险。如果能寻找到既不增加出血风险,又可以降低复发风险的替代方法就是提高临床管理的关键。 因此他们进行了研究,评估他汀类药物能否降低复发性静脉血栓
