The Effect For Patients' NO And ET-1 In Blood After Enhanced External Counterpulsation

Objective: to observe the effect for patients' NO and ET-1 in blood after enhanced external counterpulsationMethods: we choosed 120 patients who were post-percutaneoustransluminal coronary angioplasty for acute myocardial infarction or selective operation for coronary artery stenosis in the affiliated hospital. The mean age was 62.4 + 14.5 years, among the total there were 89 male patients , 31 patients are female. They were divided into two groups—tentative group and control group randomly, the tentative group taked rout drug treatment from PTCA and taked EECP from the dieb tert , one course of treatment was 30 days, the control group taked rout drug treatment. We gathered the two groups' blood simples on the first day and the thirtieth day, testing the NO and ET-1 contents.Results: the NO content steped up in tentative group post-treatment; thecontradistinction was statistical significance between pretherapy and post-treatment, P<0. 05; the NO content of control group steped up too, but there wasn' t statistical significance, P>0. 05; the contradistinction of NO content between two groups also was statistical significance, P<0.05 ; the ET-1 content steped down markedly in tentative group post-treatment , P<0.05 ; the contradistinction was statistical significance between pretherapy and post-treatment , P<0.05; the ET-1 content of control group steped down too, but there wasn' t statistical significance, P>0.05; the contradistinction of ET-1 content between two groups also was statistical significance, P<0. 05.Conclusion: experiment verificated: the patients with AMI or coronary artery stenosis take percutaneous transluminal coronary angioplasty, when they also take enhanced external counterpulsation can step up the NO content step down the ET-1 content simultaneously.
