Urine albumin excretion and related factors in patients with essential hypertension / 心血管康复医学杂志

ABSTRACT

Objective:To study urine albumin excretion (UAE) and its related factors in patients with essential hyper‐tension (EH) .Methods:A total of 113 EH patients without significant target organ damage were enrolled as EH group ,while another 92 healthy subjects were regarded as healthy control group .Ratio of morning urinary albumin to creatinine was measured and regarded as UAE index .Plasma homocysteine (Hcy) ,serum uric acid ,creatinine , blood urea nitrogen ,blood glucose ,blood lipids etc .levels were measured ,and compared between two groups Re‐sultsCompared with healthy control group ,there were significant rise in UAE ,body mass index (BMI) ,waist hip ratio ,blood pressure ,pulse pressure ,heart rate ,plasma levels of triglyceride (TG) ,low density lipoprotein choles‐terol (LDL‐C) ,serum uric acid and Hcy (P<0.05 or <0.01) ,and significant reduction in level of high density lip‐oprotein cholesterol (HDL‐C) in EH group ( P=0.001) .Pearson correlation analysis indicated that lgUAE was pos‐itively correlated with lgTG (r=0.257 ,P=0.015) and estimated glomerular filtration rate (eGFR ,r=0.284 ,P=0.007) ,and inversely correlated with lg creatinine (r= -0.277 ,P=0.008) in healthy control group ,while in EH group ,lgUAE was positively correlated BMI (r=0.231 ,P=0.014) ,lgTG (r=0.200 ,P=0.034) and lgHcy (r=0.244 , P=0.009) .Muti-factor gradual regression analysis indicated that lg TG (β=0.265 ,P=0.001) and lg Hcy (β=0.170 , P=0.012) were independently positively correlated with lg UAE , R2 =0.112.Conclusion:UAE level significantly rises in EH patients ,and it′s significantly positively correlated with plasma levels of TG and Hcy .
