Abstract:
Objective:To evaluate the effect of percutaneous coronary intervention (PCI) on mitral regurgitation (MR) in patients with acute myocardial infarction (AMI). Methods: A total of 213 AMI patients were divided int o PCI group (n = 87, PCI + medication) and medication group(n= 126, medication) according to the treatments they received. Echocardiographic examination was conducted in patients during admission and 6 months follow-up. Color Doppler was used to determine the degree of MR. Echocardiogram indices included MR degree, left ventricular end-diastolic diameter (LVEDd) ,left ventricular end-systolic diameter (LVEDs) ,left ventricular end-diastolic volume (LVEDV) ,left ventricular end-systolic volume(LVESV) ,and left ventricular ejection fraction (LVEF). Results: The overall incidence of MR was 28. 6% in 213 patients during admission. The MR incidence in patients with acute inferior myocardial infarction was higher than that in patients with other parts of infarction (34. 5% vs 22. 3% PO. 05), while the incidence in medication group increased significantly than that during admission(43. 7% vs 30. 2%,P
