快速性心律失常性心肌病发病机制的研究进展

Research progress of the pathogenesis of tachycardia-induced cardiomyopathy

心律失常性心肌病临床较常见,却极易被误诊误治。由于该类心肌病与扩张型心肌病的临床表现极为相似,因此临床上极其难辨。心律失常性心肌病的发病机制与血流动力学改变、氧化应激、心肌代谢能量异常等有关。本文阐述了快速性心律失常性心肌病的发病机制,以提高临床医师对该病的认识水平。

Arrhythmic cardiomyopathy is common in clinical practice,but it is easy to be misdiagnosed and mistreated.Because of the extremely similar clinical manifestations,it is difficult to make differential diagnosis between this kind of cardiomyopathy and dilated cardiomyopathy.The pathogenesis of arrhythmic cardiomyopathy is related to hemodynamic change,oxidative stress,abnormality of myocardial metabolic energy and so on.This paper illustrates the pathogenesis of tachycardia-induced cardiomyopathy in order to improve clinicians’understanding of the disease.
