EUR HEART J:心脏衰竭患者的药物剂量和临床结局之间的关系

2017-06-25 MedSci MedSci原创

尽管有明确的指导建议,但大多数心衰和射血分数降低的(HFrEF)患者没有达到指导原则推荐的治疗剂量。本研究探究HFrEF患者未达到指导原则推荐的治疗剂量(血管紧张素转化酶(ACE)抑制剂、血管紧张素受体阻断剂(ARB)和/或β受体阻滞剂)所引起临床结局特征和治疗指征的偏差。

背景:
尽管有明确的指导建议,但大多数心衰和射血分数降低的(HFrEF)患者没有达到指导原则推荐的治疗剂量。

目的:
探究HFrEF患者未达到指导原则推荐的治疗剂量(血管紧张素转化酶(ACE)抑制剂、血管紧张素受体阻断剂(ARB)和/或β受体阻滞剂)所引起临床结局特征和治疗指征的偏差。

方法:
此研究共招募了来自于11个欧洲国家69个中心的2516名心衰患者,他们之前未达最佳标准地治疗,并鼓励他们进行治疗。本研究中充血性心力衰竭的生物抑制剂专门用于研究血管紧张素转化酶(ACE)抑制剂、血管紧张素受体阻断剂(ARB)和/或β受体阻滞剂剂量的疗效。

结果:
151名患者在研究期间死亡,242名左心室射血分数>40%的患者被排除。平均随访时间为21个月。共研究了2100 HFrEF患者(男性:76%;平均年龄:68±12),其中22%患者达到推荐的ACE-抑制剂/ARB的治疗剂量;12%患者达到了β受体阻滞剂的治疗剂量。在欧洲国家之间有显着的差异。达到< 50%的推荐药物剂量(ACE-抑制剂/血管紧张素受体阻断剂(ARB)和β受体阻滞剂)的患者与死亡风险或心衰住院治疗增加有关。

达到≥100%的剂量的患者与达到50 - 99%的推荐剂量的患者(ACE-抑制剂/ARB和/或β受体阻滞剂)有相当的死亡风险和/或心力衰竭住院率。由于症状、副作用和非心脏器官功能障碍,未能达到推荐剂量的患者死亡率最高(ACE -抑制剂/ ARB:HR 为1.72;95% CI 为1.43 - 2.01;β-受体阻滞剂:HR为 1.70;95% CI为 1.36 - 2.05)。

结论:
与达到≥100%的推荐剂量的HFrEF患者相比,不到50%的推荐剂量(ACE-抑制剂/ ARB和β受体阻滞剂)的患者的死亡和/或心力衰竭住院的风险似乎更大。
