Abstract: Objective To study influence of percutaneous transluminal coronary angioplasty (PTCA) and stent implantation on left cardiac remodeling and left ventricular function and clinical effect of drug re-inter- vention in coronary heart disease. Methods 98 patients with coronary heart disease were divided into 4 groups one year after performing percutaneous coronary intervention (PCI), clinical and echocardiographic indexes of left cardiac remodeling and left ventricular function were examined by comparison of 4 groups of post-PCI versus pre-PCI, influences of different PCI strategy and different drug re-interventions on left cardiac remodeling and left cardiac function were analysed. Results NYHA cardiac function grade,6 minute's walk test,left atrial volume index( LAVI), left ventricular diastolic-end volume index (LVDEVI), eject fraction (EF), ventricular Wall movement loss fraction(WMLF) in 4 groups of post-PCI were better than those in pre-PCI(all P < 0.001). Those in 6 months group and 12 months group of post-PCI were also better than those in 1 week group of post-PCI(all P<0.01). LAVI, LVEDVI, EF and WMLF were significantly different among different groups of PCI strategy, and better by comparison of Group simvastatin and Group irbesartan versus group of routine drug, but little different by Group tirofiban versus group of routine drug in patients undergoing drug re-intervention of post-PCL Concluslan Left cardiac remodeling and left ventricular function in coronary heart disease have a significant improvement in post-PCIone year, suitable PCI strategy and drug re-intervention have further influence on bettering left cardiac remodeling and left ventricular function.
