Can pushing blood pressure below 120 save hearts in diabetes?
NCT ID NCT03264352
First seen Sep 14, 2026 · Last updated Sep 15, 2026 · Updated 1 time
Summary
Researchers test whether lowering systolic blood pressure to below 120 mm Hg prevents major cardiovascular events in adults with type 2 diabetes and high-normal blood pressure. The trial enrolls about 11,400 people aged 45 to 79. Participants receive either intensive treatment with Allisartan and amlodipine or standard care that starts medication only when blood pressure reaches 140/90 mm Hg.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Allisartan Isoproxil, an angiotensin receptor blocker, with amlodipine added as needed
- What this could lead to
- If intensive blood pressure lowering works, it could become a standard approach to prevent heart attacks and strokes in people with type 2 diabetes and high-normal blood pressure.
- What could go wrong
- Intensive treatment may cause side effects from blood pressure medications, such as dizziness or kidney problems, and the trial may not show a clear benefit over standard care.
