Abstract:
Objective To study the effect of PCI on left ventricular remodeling,oxidative stress and cardiac function after acute myocardial infarction (AMI).Methods One hundred and sixty-nine AMI patients were divided into PCI group (n=85) and control group (n=84).Their serum cTnⅠ,NT-proBNP,GSH,SOD levels and LVEF were measured,and their symptom and sign scores were recorded after 15 days and 6 months of PCI.Results The serum NT-proBNP level was significantly lower while the LVEF and symptom and sign scores were significantly higher in PCI group than in control group after 6 months of PCI (227.2±52.5 ng/L vs 443.3±59.2 ng/L,44.7％±6.2％ vs 38.2％±5.3％,5.7±1.4 vs 10.4±2.7,P=0.000).The serum cTnⅠ level was significantly lower in PCI group than in control group after 15 days of PCI (1.15±0.29 μg/L vs 2.41±0.36 μg/L,P=0.000).No significant difference was found in SOD and GSH between the two groups (P＞0.05).The readmission rate was 23.53％ and the total effective rate was 94.12％ in PCI group while the readmission rate was 46.43％ and the total effective rate was 71.43％ in control group after 6 months of PCI (P＜0.05).Conclusion PCI can reduce the oxidative stress,reverse the left ventricular remodeling,improve the outcome and reduce the readmission rate in early AMI patients.
