- Abstract:
- Abstract: Objective To evaluate the diagnostic value of Doppler ultrasound in the assessment of cardiovascular changes in patients with chronic renal insufficiency (CKD). Methods According to Kidney Disease Outcomes Quality Initiative (KDOQI), 80 patients with mild to moderate renal insufficiency, ie stage 2-3 CKD, were enrolled in the study, and 80 healthy volunteers in the same time period were selected as control group. The structural and functional parameters of the left ventricle as well as the structural and elastic parameters of carotid blood vessels were detected by color Doppler ultrasound. The changes of various parameters of the two groups were compared and analyzed. Results The systolic blood pressure and diastolic blood pressure of CKD patients were higher than those of healthy controls, and the heart rate of CKD patients was faster, with statistical significance (P<0.05). The comparison on structural and functional parameters of left ventricle in patients with stage 2-3 CKD and healthy controls showed that the E/A and Em in CKD patients were obviously decreased, while the E/Em, EF, LVID, DTE, LAD and LVMI were significantly increased, with statistical differences (P<0.05). E and RWT were similar in two groups, without statistical significance (P>0.05). Compared with healthy controls, patients with stage 2-3 CKD had remarkably increased PWVcf, PWVβ, Ep, IMT, D and β, with statistical differences (P<0.05). Conclusion Doppler ultrasound can be used to achieve a non-invasive and accurate assessment of left ventricular structure and functions as well as vascular structure and elasticity changes in patients with early-stage CKD, providing effective and accurate guidance for clinical treatment.
