JACC:房颤患者服用利伐沙班会增加胃肠道出血风险

2015-11-24 fsy 译 MedSci原创

胃肠道(GI)出血是口服抗凝药的常见并发症。在ROCKET AF(在房颤患者中预防卒中和栓塞试验中,生素K拮抗预防与利伐沙班每日一次口服直接Xa因子抑制进行了比较)治疗组试验中,研究人员评估了接受至少1种剂量研究药物患者GI出血情况。主要结果判定第一个到最后一个药物剂量+2天时GI出血的报道。研究人员使用预先指定的预测变量进行多变量模型检测。14236名患者中,684例患者在随访期间出现胃肠道出血

胃肠道(GI)出血是口服抗凝药的常见并发症。

在ROCKET AF(在房颤患者中预防卒中和栓塞试验中,维生素K拮抗预防与利伐沙班每日一次口服直接Xa因子抑制进行了比较)治疗组试验中,研究人员评估了接受至少1种剂量研究药物患者GI出血情况。

主要结果判定第一个到最后一个药物剂量+2天时GI出血的报道。研究人员使用预先指定的预测变量进行多变量模型检测。

14236名患者中,684例患者在随访期间出现胃肠道出血。这些患者年龄较大(平均75岁 vs 73年),女性较少。GI出血事件发生在胃肠道上部(48%)、下胃肠道(23%)和直肠(29%),治疗组之间无差异。在利伐沙班 vs 华法林治疗的患者中,有一个显著较高的主要或非主要的临床消化道出血率(3.61例事件/100病人年 vs 2.60例事件/100病人年;风险比:1.42;95%置信区间:1.22-1.66)。严重的GI出血率在治疗组之间相似(分别为0.47例事件/100病人年 vs 0.41事件/100病人年;P=0.39;0.01例事件/100病人年 vs 0.04例事件/100病人年;P=0.15),致命的胃肠道出血事件比较罕见(0.01事件/100病人年 vs 0.04事件/100病人年;1例死亡事件 vs 5例死亡事件)。与GI出血最密切相关的独立临床因素是基线贫血,胃肠道出血的病史,以及长期使用阿司匹林。

在ROCKET AF试验中,与华法林相比,利伐沙班增加了胃肠道出血。消化道出血的绝对致死率很低,在两个治疗组中也是相似的。该研究结果进一步说明,需要尽量减少口服抗凝药(患者胃肠道出血的可调控危险因素)。

CHEST:奥普力农可减少术前BNP水平升高患者肺切除术后房颤的发病率

研究人员在以前报道中提到,患者术前升高的B型钠尿肽(BNP)水平增加了肺癌手术后房颤的风险。本研究评估了特异性磷酸III抑制剂奥普力农能否降低BNP水平升高的患者接受肺切除肺癌术后房颤的发生率。该前瞻性随机对照研究包括了40名术前BNP水平升高(≥30 pg/mL),并接受预定的肺癌手术的患者。所有患者在手术时均为窦性心律。低剂量的奥普力农或安慰剂,连续输注24小时,只在麻醉诱导前开始。主要终点是
