摘要：Objectives To assess the effect of delayed coronary stent implantation on left ventricle remodeling after acute myocardial infarction(AMI).Methods Sixty patients with ST-segment elevation acute interior wall myocardial infarction (AAMI) and with the total occluded left anterior descending coronary artery conformed by angiography at 10.2±2.5(7-14) days after onset were divided into two groups according to stent implantation: stenting group and control group.Two dimensional echocardiogram was performed before operation (9.0±2.5 days after AMI)and in 2 and 6 months after onset of AAMI respectively to detect left ventricular function(LVEF), left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI) and left ventdcular wall motion abnormality (VW-MA). Results LVEF, LVEDVI, LVESVI and VWMA score were similar in two groups before operation and in 2 months after the onset of AAMI. LVEF and VWMA scores did not changed significantly at 6 months in each group compared with those before operation and in 2 months( P＞0.05 ). But LVEDVI and LVESVI were improved significantly in the successful PCI group than those before operation and in the control group(P＜0.01, P＜0.05). Conclusions Delayed coronary stent implantation in AAMI could prevent the late phase but the early phase of left ventricular remodeling after AMI.
