Thorax:抗血小板治疗可降COPD急性加重期患者死亡?

2014-04-24 小田 译 医学论坛网

有研究表明,慢性阻塞性肺疾病急性加重期(AECOPD)患者的血小板活性增加。系统炎症与COPD患者短期和长期转归差有关。英国学者对血小板增多症是否与AECOPD转归差具有独立相关性进行了探索,结果表明,在校正混淆因素后,血小板增多与COPD加重后1年死亡率增加具有相关性。抗血小板治疗可显著降低AECOPD患者的1年死亡率,并且可能有保护性作用。研究论文4月17日在线发表于《胸》(Thorax)杂志

有研究表明,慢性阻塞性肺疾病急性加重期(AECOPD)患者的血小板活性增加。系统炎症与COPD患者短期和长期转归差有关。英国学者对血小板增多症是否与AECOPD转归差具有独立相关性进行了探索,结果表明,在校正混淆因素后,血小板增多与COPD加重后1年死亡率增加具有相关性。抗血小板治疗可显著降低AECOPD患者的1年死亡率,并且可能有保护性作用。研究论文4月17日在线发表于《胸》(Thorax)杂志。

该观察性队列研究的研究对象为1343 例(49%为男性)AECOPD住院患者,患者均是通过呼吸量测定法确诊为COPD,且年龄>40岁,中位年龄为72岁。入院时记录患者的血小板计数。主要转归为患者1年时全因死亡率。次要转归包括院内死亡率和心血管事件。校正混淆变量后,利用逻辑回归法分析研究结果。

结果显示,157例(11.7%)患者有血小板增多症。血小板增多症与患者1年死亡和院内死亡均具有相关性(OR 分别为1.53和2.37)。在伴有血小板增多症的患者中,心血管住院并未显著增加(OR 1.13)。阿司匹林或氯吡格雷治疗与1年死亡率减少具有相关性(OR 0.63,P=0.003),但与院内死亡无相关性(OR 0.69 ,P=0.124)。

抗血小板药物个体化治疗浅谈

    抗血小板治疗是冠心病预防和治疗的基石。对于接受经皮冠状动脉介入治疗的冠心病患者,当前指南常规推荐双重抗血小板治疗,即小剂量阿司匹林与噻吩并吡啶类药物(如氯吡格雷)联用。然而,即使双重抗血小板治疗,仍有约2%的患者发生支架内血栓,导致急性心肌梗死。因此,如何科学、合理、恰当地应用抗血小板药物,仍是目前冠心病研究领域内亟待探讨和解决的学术问题。 1 血小板功能评估
