左心室功能下降冠心病患者的血运重建治疗

Revascularization for Patients with Coronary Artery Disease and Left Ventricular Dysfunction

冠心病是充血性心力衰竭的最常见病因。无瓣膜性病变的冠心病患者中,心力衰竭最常见由左心室收缩功能下降(左心室射血分数下降)导致,伴有左心室射血分数下降的冠心病患者预后不良。目前认为血运重建可以改善左心室射血分数下降的冠心病患者的预后,同时左心室射血分数下降患者血运重建风险高。现对左心室功能障碍的冠心病患者的血运重建治疗作一综述。

Coronary artery disease （CAD） is the most common cause of congestive Heart failure （ CHF）. In the presence of CAD, without valvular disease, CHF is most commonly caused by left ventricular systolic dysfunction （ lower LVEF）. Patients with lower LVEF have an unfavourable prognosis. At present, revascularization is thought to improve prognosis of the patients with left ventricular systolic dysfunction, but the risk is high. This paper summarizes the revascularization of CAD with lower LVEF.
