摘要
应用体外反搏(ECP)治疗40例冠心病患者,按病情分为3组,急性心肌梗死5例,不稳定型心绞痛13例,稳定型心绞痛22例。观察ECP前后内皮源性血管活性物质内皮素-1(ET-1)、组织型纤溶酶原激活物(t-PA)及其抑制剂(PAI-1)的变化。结果显示:反搏后ET-1含量、PAI-1活性明显下降;t-PA活性明显回升。提示ECP治疗冠心病除血流动力学、血液流变学等因素外,还可改变内皮源性血管活性物质的活性,从而对ECP治疗冠心病的机理提出了新的观点。
40 patients with coronary heart disease treated by external counter pulsation(ECP) were divided into three groups:acute myocardial infarction(n=5),unstable angina pectoris(n=13),stable angina pectoris(n=22).Plasma endothelin 1(ET 1),tissue type plasminogen activator(t PA) and plasminogen activator inhibitor 1(PAI 1) were studied before and after ECP. The results showed that plasma ET 1 and PAI 1 decreased significantly while plasma t PA increased obviously after ECP. It is indicated that ECP treated coronary heart disease through changing levels of endothelium derived vasoactive substances besides hemodynamics and hemorrheology factors. So the new viewpoint is put forward about treating mechanisms of ECP for coronary heart disease.
