摘要
目的探讨心力衰竭患者室性心律失常的发生机制与预后。方法对心力衰竭患者的病理生理改变,血流动力学改变,神经内分泌变化,治疗药物及预后进行分析。结果心力衰竭患者的死亡率很高,过去认为心力衰竭患者的死亡原因主要是心力衰竭不断发展所致,而今多数研究证实,心力衰竭患者每年的死亡率中50%为猝死,而其中大多数是由快速性VA所致。结论对已明确合并器质性心脏病的患者,特别是合并缺血性心脏病和心功能不全的患者,室性心律失常的发生具有预后意义,应作为确定临床治疗方案、并进行强化治疗和预防的依据。
Objective To investigate the pathogenesis and prognosis of heart failure patients with ventricular arrhythmias.MethodsAnalyzed the change of pathophysiology, hemodynamic changes, neuroendocrine changes, drug therapy and prognosis of heart failure patients.Results The mortality rate of heart failure patients was very high, people used to think that the cause of death in patients with heart failure was mainly caused by the continuous development of heart failure, but now most studies confirmed that sudden death accounts for 50% in the yearly mortality rate of heart failure patients, most of which was induced by celerity VA. Conclusion To the deifned merge organic heart disease patients, especially patients with ischemic heart disease and heart failure, the occurrence of ventricular arrhythmias has prognostic signiifcance, thus, it should serve to determine the clinical treatment programs, and to strengthen the basis of the treatment and prevention.
