Abstract Objective: To explore the mechanical synchrony of patients with urinary cardiomyopathy and the clinical value of left ventricular function by means of 3DE evaluation. Methods: 60 patients with uremia who had not received dialysis in August 2016 -2017 in our hospital in August were selected. A total of 40 outpatients were randomly collected. The latest Siemens Acuson SC2000 ultrasonic diagnostic apparatus was used for image analysis. The left ventricular ejection fraction (LVEF) and left ventricular end-systolic volume (LVESV) and left ventricular end-diastolic volume (LVEDV) were compared, and the synchrony and left ventricular short-axis tangential strain rates were compared. Results: HR, LVEDV and LVESV in uremia myocardial damage group (UMD) were higher than those in healthy group (P<0.05), and LVEF was lower than that in healthy group (P<0.05). There were significant differences in SDI-16, SDI-17, DDI-16 and DDI-17 between the two groups. The UMD group was higher than the control group (P<0.05). The basal, middle and apical strain rates in UMD group were lower than those in control group (P<0.05). Left ventricular systolic function was negatively correlated with contraction asynchrony index in UMD group (r=-0.751, P<0.01). Conclusion: For UMD patients, the synchrony of left ventricular contraction and the synchrony of diastole are relatively poor. Real-time three-dimensional echocardiography (RT-3DE) is a fast, simple and new method for evaluating left ventricular function and synchronization in UMD patients.
