Abstract:
Objective To explore the association between urinary microalbumin-to-creatinine ratio (ACR) and brachial-ankle pulse wave velocity (baPWV) in hypertensive patients.Methods A total of 877 primary hypertension patients were enrolled in this trial from September 2009 to December 2012,and were randomly recruited and patients were divided into normal ACR group (ACR < 30 mg/g,n =723),microalbuminuria group (30 mg/g ≤ ACR < 300 mg/g,n =136) and macro-albuminuria group (ACR ≥300 mg/g,n =18).baPWV was measure by automatic pulse wave velocity measuring system.Results The baPWV values in patients of micro-albuminuria group and macro-albuminuria group were significantly higher than in the normal ACR group (all P < 0.05).The baPWV value of macro-albuminuria group was significantly higher than in the micro-albuminuria group (P < 0.05).Linear correlation analysis revealed that ACR was positively correlated with baPWV (r =0.413,P < 0.01).Multiple linear regression analysis showed that ACR independently correlated with baPWV in patients with primary hypertension (β =0.29,R2 =0.112,P < 0.01) after adjusting for age,sex,body mass index,systolic blood pressure,diastolic blood pressure,blood glucose,total cholesterol,low density lipoprotein,high density lipoprotein and triglyceride.Using ACR < 30 mg/g and ACR ≥ 30 mg/g as dichotomous variable,binary logistic regression analysis showed that ACR≥30 mg/g was also a risk factor of the ascending baPWV in primary hypertension patients (OR:1.73,95% CI:1.62-2.98) after adjusting the traditional cardiovascular risk factors.Conclusion ACR is positively correlated to baPWV in primary hypertension patients,and the ascending baPWV is a risk factor of early renal dysfunction in primary hypertension patients.
