Abstract:
Objective To investigate the relationship between 24-hour ambulatory blood pressure and urine microalbumin(UMA)level in the elderly with non-diabetic essential hypertension.Methods One hundred elderly cases with essential hypertension were selected from the Department of Geriatrics,the Sixth People's Hospital,Shanghai and divided into two groups,one with UMA less than 30 mg/24h,and the other with UMA equal to or greater than 30 mg/24h.Ambulatory blood pmssure,serum level of creatinine (sCr),UMA and other characteristics were measured for all the subjects studied and compared to find possible relationship between blood pressure and UMA.Results Level of sCr,diastolic blood pressure at night (nDBP),24-hour average blood pressure,average blood pressure at night were all significantly higher in the group with UMA equal to or greater than 30 mg/24h than that with UMA less than 30 mg/24h(P<0.05 or P<0.01). Multivariate logistic regression analysis indieated that both sCr and nDBP were indispensable predictors for high microalbuminuria in patients with essential hypertension.Conclusions Ambulatory blood pressure monitoring,especially blood pressure variation at night,has more important predictive value for severity of renal damage caused by hypertension in the elderly with non-diIlbetic essential hypertension.
