Cheap Diuretic Spironolactone Lowers Blood Pressure After Stroke
TLDR
- Adding low-cost spironolactone after stroke helped patients reach blood pressure goals nearly twice as often as usual care.
- The REDUCE trial randomized 160 stroke survivors to spironolactone plus usual care or usual care alone, tracking home blood pressure for six months.
- Spironolactone, an inexpensive diuretic, could reduce recurrent strokes and improve quality of life for stroke survivors with uncontrolled hypertension.
- Spironolactone, a diuretic that blocks aldosterone, lowered systolic blood pressure by nearly 8 mm Hg in stroke survivors.
Impact - Why it Matters
This news matters because stroke is a leading cause of disability, and nearly one in four survivors will have another stroke—yet up to 80% of recurrent strokes can be prevented, largely by controlling blood pressure. The REDUCE trial shows that adding an inexpensive, widely available diuretic like spironolactone can produce meaningful blood pressure reductions and help more survivors reach recommended targets, potentially lowering the risk of future strokes and heart attacks. For patients and clinicians, the findings suggest that starting spironolactone sooner after a stroke, combined with routine home blood pressure monitoring, could be a simple and cost-effective strategy to improve post-stroke outcomes. While larger studies are needed to confirm whether this translates into fewer recurrent strokes, the results offer a promising, practical approach to addressing a major modifiable risk factor in a vulnerable population.
Summary
Stroke survivors with uncontrolled high blood pressure who added the inexpensive diuretic spironolactone to their post-stroke care achieved significantly lower blood pressure and were nearly twice as likely to reach recommended targets compared to those receiving usual care, according to preliminary late-breaking research presented at the American Heart Association’s Scientific Sessions 2026 in Chicago. The REDUCE trial, led by co-lead author Jordana B. Cohen, M.D., M.S.C.E., FAHA, of the Perelman School of Medicine at the University of Pennsylvania, enrolled 160 adult stroke survivors across five U.S. medical centers. At three months, participants taking spironolactone daily had home systolic blood pressure nearly 8 mm Hg lower on average than the standard care group (about 126 mm Hg vs. 133 mm Hg), and 52% reached the recommended goal of less than 130/80 mm Hg compared with 30% in the standard care group. The medication was well tolerated, with serious side effects similar between groups.
Cohen noted that high blood pressure is a leading risk factor for recurrent stroke, yet many survivors struggle to reach targets. Spironolactone, a low-cost diuretic typically used as a fourth-line blood pressure medication, blocks aldosterone to help the body excrete salt and water. The trial included both ischemic stroke and intracerebral hemorrhage survivors, and an exploratory analysis suggested greater blood pressure reductions when spironolactone was started within three months after stroke. The study was funded by a Bugher Center grant from the American Heart Association and is considered preliminary until published in a peer-reviewed journal.
