Abstract：
The article presents a clinical case of a patient with severe chronic heart failure of ischemic origin. In 2020, the patient with a long history of ischemic heart disease, as confirmed by clinical data and instrumental examination, was diagnosed with severe cardiomegaly and NYHA class III chronic heart failure. The course of heart failure was aggravated by the presence of arrhythmia in the form of atrial fibrillation. At the first stage, a drug therapy and lifestyle modifications were recommended. In 2021, a beneficial tendency in clinical and instrumental indexes was observed, which made it possible to move on to the surgical stage of treatment. A coronary artery bypass grafting was performed with ablation of the left atrial posterior wall using the \"box lesion\" technique. A follow-up examination performed a year later showed normalization of the left ventricular dimension and recovery of its contractile function. The symptoms of heart failure regressed to the level of NYHA functional class I; no relapses of atrial fibrillation were detected. The patient continues to receive recommended drug therapy.
摘要：
本文介绍了一例缺血性严重慢性心力衰竭患者的临床病例。2020年，患有缺血性心脏病的患者，经临床数据和仪器检查证实，被诊断为严重心脏肥大和NYHAIII级慢性心力衰竭。以心房颤动为形式的心律失常的存在加剧了心力衰竭的进程。在第一阶段,推荐药物治疗和生活方式改变.2021年，观察到临床和仪器指标的有益趋势，这使得进入手术治疗阶段成为可能。使用“框损伤”技术进行冠状动脉旁路移植术，并消融左心房后壁。一年后进行的随访检查显示左心室尺寸正常化，其收缩功能恢复。心力衰竭的症状恢复到NYHA功能I类水平；未检测到房颤复发。患者继续接受推荐的药物治疗。
