Abstract:
Objective To investigate the serum level of placental growth factor (PLGF) and explore its relationship with left ventricular structure and function in chronic kidney disease (CKD) patients.Methods Seventy-two non-dialysis CKD patients and sixteen age-and sex-matched healthy controls were included in this study.Serum PLGF level was measured by ELISA.Cardiac structure and function were assessed by two dimensional echocardiography.Results (1)The serum level of PLGF in CKD patients[3.32(2.97,19.77) ng/L] was significantly higher compared to the healthy controls [2.33(2.27,2.49) ng/L] (P ＜ 0.01).It progressively increased with the decline of renal function (P＜ 0.05/6).(2)The interventricular septum (IVS),left ventricular posterior wall (LVPW) was significantly higher while the ejection fraction was significantly lower in CKD patients.(3)The serum PLGF level was higher in patients with left ventricular hypertrophy (LVH) than those without LVH [19.05(3.31,21.05) ng/L vs 2.99(2.60,3.32) ng/L,P ＜ 0.05].The prevalence of LVH in the group above median PLGF level was significantly higher than that in the group below the median PLGF level (70％ vs 18％,P ＜ 0.01).(4)PLGF level was positively correlated with left ventricular mass index (LVMI),systolic pressure,diastolic pressure,24 h urine protein,Scr,UA,BUN,iPTH,the history of high blood pressure and was negatively correlated with LVEF,hemoglobin,albumin,eGFR (P ＜ 0.05).Multiple regression results showed that UA,Scr,LVEF,Hb were associated with PLGF level independently (P ＜ 0.01).Conclusions CKD patients have elevated level of PLGF.It has a relationship with cardiac structure and function.It may participate in the occurrence of cardiovascular events.
