Abstract:
Objective:To quantitatively evaluate the global myocardial work of left ventricle in patients with chronic kidney disease (CKD) by left ventricular pressure-strain loops (PSL).Methods:Forty patients with chronic kidney disease (CKD) in Henan Provincial People′s Hospital from February 2019 to October 2019 were chosen as case group.According to the decreased level of the glomerular filtration rate (GFR), CKD patients were divided into CKD 2-3 stage group( n=20) and CKD 4-5 stage group( n=20), and 20 healthy volunteers were selected as control group.The working parameters of the global left ventricular myocardium including the global work index (GWI), the global constructive work (GCW), the global wasted work (GWW), the global work efficiency (GWE) were measured by the left ventricular PSL, and the differences of the parameters among the three groups were compared. Results:Compared with the control group, the GWI, GCW, GWW in the CKD 2-3 stage group and CKD 4-5 group were significantly higher and the GWE was lower than those in the control group differences were all (all P<0.05). Compared with the CKD 2-3 stage group, the GWI and GCW of the CKD 4-5 stage group were increased (all P<0.05), but there were no significant differences in GWW and GWE ( P>0.05). Conclusions:Left ventricular PSL provides a new method for evaluating the changes of left ventricular systolic function in patients with CKD.
