Int J Cardiol:急性心力衰竭吗啡治疗的不良剂量依赖效应

2019-06-13 xing.T MedSci原创

由此可见,吗啡给药与院内死亡率和机械通气需求有显著的剂量依赖性风险。

心力衰竭(HF)由于其高发病率和死亡率而成为美国的主要公共卫生问题。HF的诊断年龄将改善负担量化、预算、疾病监测和干预评估。研究人员旨在确定美国20岁及以上患者在诊断HF的中位年龄和诊断年龄较小的驱动因素。

一个多世纪以来,吗啡一直是急性心力衰竭(AHF)的关键疗法。AHF中吗啡治疗的证据仍存在争议。近日,心血管领域权威杂志International Journal of Cardiology上发表了一篇研究文章,该研究旨在评估吗啡对AHF患者的治疗效果。

该研究使用了一组13888例初诊为AHF的患者,使用26个临床变量生成倾向得分匹配。主要终点包括院内死亡率和有创机械通气。次要终点包括无创通气,需要使用正性肌力药和急性肾损伤(AKI)。

入院后第一天,761名(5.5%)患者接受了吗啡治疗。倾向评分匹配产生672个患者配对。吗啡治疗组患者的有创通气发生率(7.4%)高于非吗啡组(3.6%),比值比为2.13(95%CI为1.32-3.57,P=0.007)。吗啡组的住院死亡率(17.4%)也高于匹配的非吗啡组(13.4%),比值比为1.43(95%CI为1.05-1.98,P=0.024)。对于有创通气的终点(趋势P=0.005)和死亡率(趋势P=0.004),吗啡的不良反应存在显著的线性剂量-反应关系。吗啡与所有次要终点显著增加相关:无创通气(OR为2.78,95%CI为1.95-3.96);使用正性肌力药(OR为3.50,95%CI为2.10-5.82)和AKI(OR为1.81,95%CI为1.39-2.36)。一项具有里程碑意义的分析表明,队列之间的出院后存活率没有差异。

由此可见,吗啡给药与院内死亡率和机械通气需求有显著的剂量依赖性风险。

由此可见,重复测量的mir-1306-5p与AHF患者的不良临床预后相关,即使包括NT-proBNP内的多变量进行调整后。然而,基线mir-1306-5p并没有明显增加NT-proBNP的区分能力。低丰度、心脏含量不丰富MyomiRs家族经常很难检出,这就需要开发更灵敏的分析方法。
