Abstract

OBJECTIVE:

To study the relationship between microalbuminuria and cognitive impairment in primary hypertensive patients.

METHODS:

A total of 200 hypertensive patients were included in this study. Blood pressure, body height and weight, total cholesterol, triglyceride, fasting plasma glucose, 2 hour-postprandial blood sugar, insulin level and urine protein were measured. Microalbuminuria and urine creatinine were determined in patients without proteinuria. The risk stratification of hypertension was evaluated. The cognitive function and calculate scores were tested by the Mini Mental State Examination (MMSE) and patients were divided into two groups: > 24-scores were classified as normal cognition group, < or = 24-scores as impaired cognition group.

RESULTS:

Among the 200 hypertensive patients, proteinuria was detected in 25 patients. There was no significant difference in the cognitive function between patients with and without proteinuria (P > 0.05). There were significant differences on age, educational level, occupation, smoking, history of coronary heart disease, history of cerebrovascular disease, the risk stratification of hypertension, microalbuminuria/creatinine ratio, postprandial insulin level, cholesterol and diastolic blood pressure between normal cognition function group and impaired cognition function group (all P < 0.05). Multivariate logistic regression analysis showed that microalbuminuria, educational level and the risk stratification of hypertension were significantly correlated to cognition impairment (all P < 0.05).

CONCLUSIONS:

Educational level, the risk stratification of hypertension and microalbuminuria are associated with cognitive impairment in this patient cohort.
