心房颤动合并心力衰竭的射频导管消融治疗

Ridiofrequency Catheter Ablation of Atrial Fibrillation in Patients with Heart Failure

心房颤动和心力衰竭是心血管领域的高发病,二者常常合并存在,有着共同复杂的病理生理学机制。恢复和维持窦性心律可明显改善心功能,但心力衰竭患者通常合并全身多脏器功能不全,本身对药物代谢性低,对抗心律失常药物的耐受性相对更差,多项研究表明射频导管消融可以降低心力衰竭合并心房颤动患者的远期死亡率,提高运动耐量,改善生存质量。

Atrial fibrillation and heart failure both have become major cardiovascular epidemics and are often detected in the same patient.Atrial fibrillation and heart failure have a common complex pathophysiological mechanism.Restoring and maintaining sinus rhythm can improve cardiac function,but the benefits of rhythm control in heart failure patients may have been offset by side effects of antiarrhythmic drugs.However,radiofrequency catheter ablation could achieve rhythm control,which is associated with reduction in hospitalization and mortality,enhancing exercise tolerance and improving patients’live quality.
