Change of left ventricular cardiac function in patients with coronary artery disease

Objective: To examine change of left ventricular cardiac function in patients with coronary artery disease. Methods.- Seventy-eight inpatients with coronary artery disease (CAD) complicated with left ventricular dysfunction were divided into stable angina pectoris (SA), unstable angina pectoris (UA), acute myocardial infarction (AMI), old myocardial infarction (OMI) groups.Cl, TPR, PEP, LVET. EF. SV, CO. A peak, E peak, PER, NPERs-1 were measured by noninvasive autonomic detector and color Doppler eehocardiography. Results: Compared with control group left ventricular function (CI, EF, SV, CO, E peak, PER and NPERs-1) significantly decreased (P 0. 01, all), TPR, PEP/LVET, A peak and A/E increased (P0. 01, all) in OMI and AMI groups; left ventricular function decreased in UA and SA groups (P0. 05-0. 01). The decrease of left ventricular function in AMI and OMI groups was more than those of UA and SA groups (P0. 05). Conclusion; Left ventricular dysfunction is association with severity of coronary artery disease.
