| Objective This study aimed to finding the better method that evaluate curative effect of percutaneous coronary intervention(PCI)early, accurately,and conveniently that improve the ventricular function.Methods Changes of left ventricular function in 43 coronary heart disease(CHD) patients were evaluated by Echocardiogram and BNP before and after PCI operation.Results BNP in 43 patients after PCI group is lowerer than that before PCI(p<0.05); There was not statistics in changes of Echocardigraphy before and after PCI(p>0.05); The decreasing degree of concentration of BNP gradually reduces after PCI operation along with extending time from MI to PCI, but the concentration of BNP still drops in patients of PCI 3 to 6 months after MI. Conclusions BNP is a sensitive index that diagnose heart failure and that evaluate PCI of improving left ventricular function; BNP is better than UCG in evaluating PCI;The earlier time of PCI after myocardial infarction(MI) is the better,but,if the time of PCI after MI is in 3 to 6 monthes,PCI may also be applied. |
