Abstract:
Objective To investigate the relationship between interventricular septum thickness(IVS) and renal function in patients with diabetes mellitus.Methods Two hundred and sixty-five patients of type 2 diabetes without dialysis were enrolled in a cross-sectional study.According to their IVS,the patients were divided into normal group (IVS≤ 11 mm) and higher IVS group (IVS ＞ 11 mm).All patients according to evaluated glomerular filtration rate (eGFR) level were divided into eGFR≥60 ml· min-1 · (1.73 m2) 1 group and eGFR ＜ 60 ml· min-1 · (1.73 m2)-1 group.The demographic characteristic,biochemical examination,eGFR,and proteinuria of different groups were compared.Pearson or spearman correlation was used to analyze the relationship between eGFR,IVS and other parameters.eGFR ＜ 60 ml · min-1 · (1.73 m2)-1 and IVS thickening were analyzed by binary logistic regression.Risk factors affect the prognosis of renal function in patients with diabetes mellitus were analyzed by Cox regression analysis.Results Compared with normal group,patients in the higher IVS group had higher systolic pressure (P=0.002),their level of Scr,BUN,24 h urinary protein were increased (all P ＜ 0.05),while the level of eGFR,albumin (ALB),hemoglobin (Hb) and fasting blood glucose were decreased (all P ＜ 0.05).The prevalence of hypertension was increased (81.16％ vs 58.67％,x2=11.273,P=0.001),and there was also a difference in the proportion of patients in each stage of CKD (x2=34.593,P ＜ 0.001).Correlation analysis showed that IVS was positively correlated with BMI,systolic BP,Scr,BUN,24 h urinary albumin,24 h urinary protein (all P ＜ 0.05),while negative correlation was observed between the thickened degree of IVS and Hb,albumin,eGFR and total calcium (all P ＜ 0.05).It's worth noting that IVS also correlated with history of hypertension and degree of renal injury (all P ＜ 0.01).Logistic regression analysis showed that longer duration of diabetes,higher systolic pressure and BUN were independent risk factors for eGFR ＜ 60 ml·min-1·(1.73 m2)-1 (all P ＜ 0.05),while higher Hb and Alb were independent protective factors for eGFR ＜ 60 ml· min-1· (1.73 m2)-1 (all P ＜ 0.05).Logistic regression analysis also showed that the baseline increased Scr was independent risk factor for interventricular thickening (P ＜ 0.05),while the increase of fasting blood-glucose was independent protective factor for interventricular thickening (P ＜ 0.05).Cox regression analysis showed that interventricular thickening was an independent risk factor in predicting the progression of type 2 diabetes (HR=1.396,95％ CI=1.098-1.774,P=0.006).Conclusion Interventricular septum thickness is closely related to the state of renal function,as well as is an independent risk factor to predict kidney function decline in patients with type 2 diabetes.
