JACC:心绞痛对于冠心病、心衰、左室收缩功能不全患者的重要性

2015-11-03 崔倩 译 MedSci原创

左心室(LV)收缩功能不全,冠状动脉疾病(CAD),心绞痛患者往往被认为比那些没有心绞痛的患者有更坏的预后,但能从冠状动脉旁路移植术(CABG)手术有更大的预后益处。这项研究调查了:1)是否心绞痛与预后较差相关; 2)是否心绞痛确定哪些患者可以从CABG手术获得更大的生存益处;3)CABG是否改善LV收缩功能障碍和CAD的心绞痛患者临床效果。研究人员进行了STICH(外科治疗缺血性心力衰竭)试验,

左心室(LV)收缩功能不全,冠状动脉疾病(CAD)的患者发生心绞痛往往被认为比那些没有心绞痛的患者有更坏的预后,但能从冠状动脉旁路移植术(CABG)手术有更大的预后益处。

这项研究调查了:1)心绞痛是否与预后较差相关; 2)心绞痛是否可以确定哪些患者可以从CABG手术获得更大的生存益处;3)CABG是否改善LV收缩功能障碍和CAD患者的心绞痛的临床效果。

研究人员进行了STICH(外科治疗缺血性心力衰竭)试验,其中1212例射血分数≤35%和CAD患者被随机分配接受CABG或药物治疗的。多变量Cox和逻辑模型被用来评估长期的临床结果。

在基线时,770例患者(64%)报告有心绞痛。在分配到药物治疗的患者中,有和无心绞痛患者的全因死亡率相似(风险比[HR]:1.05;95%可信区间(Cl):0.79〜1.38)。患者是否有心绞痛CABG的效果是相似的:有心绞痛(HR:0.89;95%Cl:0.71〜1.13),无心绞痛(HR:0.68;95%Cl:0.50〜0.94,相互P=0.14)。分配到CABG的患者更可能比那些分配到单纯药物治疗的患者改善心绞痛(比值比:0.70;95%Cl:0.55〜0.90;P<0.01)。

心绞痛不能预测药物治疗左室收缩功能不全和冠状动脉疾病患者的各种原因的死亡率,也不能确定哪些患者可以从CABG获得更大的生存益处。然而,CABG手术确实比单独药物治疗能更大的程度的改善心绞痛。
