Evaluation Of Left Ventricular Systolic And Diastolic Function After Percutaneous Coronary Interventions (PCI)

Objective To investigate the short-term ( <6 months ) effect on left ventricular systolic and diastolic function after percutaneous coronary interventions ( PCI ) . Methods All patients were examined by echocardiography about left ventricular systolic and diastolic function index : left atrial dimension (LA), end-diostolic dimension of left ventricle (LVDd), end-systolic dimension of left ventricle (LVDs) fractional shortening of left ventricular short-axis (FS), left ventricular ejection fraction (LVEF), E wave, A wave E/A ratio and the wall motion segmental dysfunction before coronary angiography ( CAG ) Seventy-five patients with coronary heart disease underwent PCI successfully and reexamined by echocardiography within 6 months after PCI . They were respectively divided to acute myocardial infarction ( AMI )group with non- myocardial infarction group and diabetic mellitus group with non-diabetic mellitus group based on their clinic situations All of their echocardiographic index post-PCI were compared with those of pre-PCI The echocardiographic index after PCI were also compared between groups Results (1) The left ventricular systolic function of 75 patients improved after PCI The left atrial diameter (LA), the left ventricular diastolic diameter (LVDd) and the left ventricular systolic diameter (LVDs) decreased ( P = 0.008, 0 000 and 0.000, respectively ) and the left ventricular ejection fraction (LVEF) increased ( P = 0 048 ) The rate of the wall motion segmental dysfunction decreased from 69% to 43% But the left ventricular diastolic function improved little , only E wave decreased ( P - 0 454 ) (2) Both of the left ventricular systolic functions...
