Research on cerebral infarction patients with mild renal impairment / 中国医师进修杂志

ABSTRACT

Objective To investigate the risk factors of mild renal impairment in cerebral infarction patients.Methods One hundred and fifty patients with cerebral infarction were enrolled from June 2012 to June 2013,and all patients received cranial magnetic resonance imaging at the first week.The clinical data of patients were recorded in detail,24 h microalbuminuria (mALB) was detected,renal function was assessed.According to mALB,the patients were divided into normal renal function group (105 cases) and mild renal dysfunction group (45 cases).Clinical risk factors between 2 groups were compared,and multivariate regression analysis was done.Results Age in mild renal dysfunction group was greater than that in normal renal function group [(67.04 ±9.37) years vs.(63.01 ± 11.18) years],the incidence of hypertension and multiple lacunar infarction were higher than those in normal renal function group[57.8％ (26/45) vs.33.3％ (35/105),57.8％ (26/45) vs.22.9％ (24/105)],leukoaraiosis grade was higher than that in normal renal function group,there were significant differences (P ＜ 0.05 or ＜ 0.01).Logistic regression analysis found that hypertension (OR =1.04 1,P =0.045) and leukoaraiosis (OR =2.048,P =0.000) were independent risk factors for cerebral infarction patients with mild renal impairment.Conclusions The incidence of mild renal impairment is higher in cerebral infarction patients,and is closely related to hypertension and leukoariosis.Early detection of 24 h mALB in cerebral infarction patients has important clinical significance.
