Abstract:
The right chest electric admittance plethsmography (RCEAP) is a simple no invasive and reliable method in detecting the blood flow volume in the pulmomary artery and vein, an indirection of the left heart function. In this clinical study, the RCEAP, left heart catheterization for measurement of LVEDP and coronary angiogram and echocardiography for investigating the LVEF were performed on 34 patients with coronary heart disease. Of these 34 patients,24 had single or no left vessel lesion (Group A), 10 had left main coronary artery or its double branches lesions (Group B) ;8 underwent percutaneous trans-lumin coronary angioplasty (PTCA)and 10 had coronary artery bypass graft (CABG).The data obtained were analysed and compared to evaluate their respective diagnostic values. Correlation analysis demonstrated the values of hc/hz ratio, ha/hz ratio were moderated with LVEDP(r = 0. 68 or 0. 73,P
