ABSTRACT: Objectives
To compare the effects of three antihypertensive medications on cerebral hemodynamic and cognitive function in hypertensive individuals with executive dysfunction.Design
Double-blind randomized clinical trial.Setting
Community.Participants
Fifty-three individuals aged 60 and older with hypertension and executive dysfunction.Intervention
Lisinopril, candesartan, or hydrochlorothiazide for 1 year.Measurements
Cerebral blood flow velocity (BFV; transcranial Doppler ultrasonography during rest, sitting, standing, hypercapnia, and hypocapnia), cognition, and blood pressure were measured at baseline and after 6 and 12 months. Linear mixed models were used to compare the three groups.Results
Of the 53 participants, 47 had successful insonation (mean age 72; 70% white; 57% women). There was a tendency toward an increase in BFV in the candesartan group and a decrease in the lisinopril and hydrochlorothiazide groups (between-group P = .57) that was significant in those with low BFV at baseline (
