Abstract
BACKGROUND: Thiazides have been used for the control of blood pressure and primary prevention of ischemic stroke. No previous studies have assessed the influence of thiazides on functional prognosis after ischemic stroke. METHODS: Demographics, prestroke conditions, poststroke National Institutes of Health Stroke Scale score, and clinical and laboratory parameters were prospectively registered in 216 Taiwanese patients. One hundred forty patients who completed follow-up 3 months after experiencing ischemic stroke were assessed with the modified Rankin scale as functional prognoses. RESULTS: Twenty-one patients used thiazide to control hypertension before experiencing ischemic stroke. No differences of stroke subtypes and comorbidities before stroke were observed between the 2 groups. The emergency department National Institutes of Health Stroke Scale was lesser among thiazide users (4 [2-7] versus 6 [4-16], P = .02). Among 140 patients who completed follow-up in 90 days, thiazide users had more favorable functional status (modified Rankin scale ≤2: 42.4% versus 26.9%, P = .02, odds ratio 3.34, 95%, confidence interval .130-.862). CONCLUSION: Hypertensive patients treated with thiazides long term had a lesser severity of stroke and better functional outcomes after ischemic stroke.
