Title: The study on recovery extent of left ventricular damage in ACS after PCI by echocardiography
Abstract: Objective To quantitatively evaluate the recovery extent of left ventricular(structures,motion and left ventricular systolic function)damage and in acute coronary syndromes(ACS)after percutaneous coronary intervention(PCI) by echocardiography(ECHO).Methods This study Selected 40 hospitalized patients who were diagnosed as ACS with significant coronary artery stenosis or infarction undergoing coronary artery angiography(CAG) and PCI.We compared the changes of parameters and ultrasonic features of ECHO between before and after PCI.Received 20 normal subjects whose CAG were negative as control group.Results The changes of parameters of ECHO of 40 cases between before and after PCI:LVEF,FS,LVDd,LVVd were significant higher after PCI than those before PCI(P0.001,0.001,0.05,0.05);LVDs was significant lower after PCI than those before PCI(P0.05);the detective cases of lower left ventricular systolic function after PCI were significant less than those before PCI(P0.001);the detective cases of left ventricular dilation,the thickness of IVS and LVPW,incidental rate of regional wall motion abnormal(RWMA) and others were no significant differences before and after PCI.ConclusionECHO is the effective tool to quantitatively evaluate the recovery extent of left ventricular damage in ACS after PCI.
