Objective To evaluate the effect of full-volume three-dimensional echocardiography in evaluation of left heart function of patients with coronary heart disease. Methods A total of 50 normal controls and 50 patients with coronary heart disease were enrolled, and underwent threedimensional echocardiography. The three-dimensional ultrasound images were collected and analyzed.The left ventricle and the 17-segment volume-time curve were obtained. The local ejection fraction (REF), local stroke volume (RSV), local end-systolic volume (RESV), left ventricular 17-segment local end-diastolic volume (REDV) were compared. Results The levels of RESV and REDV in the coronary heart disease group were higher, and the REF level was lower than that in the normal group (P ＜ 0. 05). The levels of RESV and REDV in the coronary heart disease group were significantly decreased, and the postoperative REF was significantly increased (P ＜ 0. 05). The preoperative REF of the coronary heart disease group was significantly lower than that of the normal group (P ＜0. 05), and the postoperative REF level was increased to different extents to normal range (P ＜0. 05). Conclusion Full-volume three-dimensional ultrasonography can be used to accurately assess the cardiac volume and cardiac function of ischemic remodeling in coronary heart disease.
