摘要
心肌梗死后心脏交感神经分布改变,使去神经支配和神经过度支配区域共存,成为心肌梗死后室性心律失常发生和猝死的重要因素。交感神经重构的机制已经成为研究的热点问题,可能为将来心肌梗死后心律失常的治疗提供一个新的方向。
The distribution of cardiac sympathetic nerve changes after myocardial infarction. It causes the regional co - existence of denervation and excessive innervation,which becomes an important factor of ventricular arrhythmia and sudden death after myocardial infarction. The mechanisms of sympathetic remodeling have become a hot issue, which may be offer a new direction for the therapy of arrhythmia after myocardial infarction in the future.
