Objective To investigate the therapeutic efficacy of coronary heart disease intervention and effect on vascular endothelial growth factor(VEGF) and C-reactive protein(CRP) levels.Methods 127 cases with angina and myocardial infarct were done PCI(PTCA/PTCA percutaneous transcoronary angioplasty+stenting),the therapeutic efficacy was observed,and perioperative VEGF and CRP levels were determined.Results 146 brackets cases were placed in 127 cases,all brackets were successfully inserted into target vascular lesion sites;2 cases with two rami pathological changes given up PTCA because guide wire couldn't pass anterior descending branch narrow part;4 cases took place no re-flow phenomenon,operation achievement ratio was 95.3%.The levels of post-operative CRP increased 142.9%,but the levels of post-operative VEGF decreased 31.9%.Conclusion The therapeutic efficacy PCI on coronary heart disease is satisfactory monitoring CRP and VEGF in blood serum could be helpful to understand the therapeutic efficacy and inflammation degree.
