Association between eprosartan-based hypertension therapy and improvement in cognitive function score: long-term follow-up from the OSCAR observational study.

Abstract

OBJECTIVE:

The Observational Study on Cognitive function And systolic blood pressure Reduction (OSCAR) was designed to evaluate the impact of eprosartan-based therapy on cognitive function in a cohort of 25,745 hypertensive subjects followed for six months.

METHODS:

In this supplementary analysis, we studied the relationship between eprosartan-based therapy and cognitive function (assessed using the Mini-Mental State Examination (MMSE)) after 12-month follow-up of 3600 patients (the long-term follow-up on-treatment population).

RESULTS:

Reduction in blood pressure was sustained over 12 months, with mean systolic blood pressure/diastolic blood pressure 130.9/79 mmHg at one year, compared with 164.3/92.8 mmHg at baseline (p<0.001). The overall mean MMSE score at completion of 12-month follow-up was significantly increased from baseline (27.8 ± 2.7 vs. 26.3 ± 3.5; p<0.001). The increase in MMSE score was observed when the population was stratified by age (p<0.001) and in a subgroup of patients with cerebrovascular disease at baseline (n=290) (p<0.001, 12 months vs. baseline).

CONCLUSIONS:

In this cohort of patients, use of eprosartan-based treatment for one year was associated with sustained reduction in blood pressure and stabilization or improvement of MMSE scores. These data are supportive of a role for blood pressure control in the prevention or delay of cognitive decline.
