Could a simple arm cuff boost heart health after bypass?
NCT ID NCT04779008
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study is testing whether doing repeated cycles of arm blood pressure cuff inflation (called remote ischemic preconditioning) over several months can improve blood flow to the heart muscle in people who have had coronary artery bypass surgery. The researchers will measure heart blood flow using imaging scans and track heart-related events for one year. 210 participants who need bypass surgery for three blocked arteries are being recruited.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
remote ischemic preconditioning (RIPC) - brief cycles of arm blood pressure cuff inflation and deflation
What this could lead to
If it works, this could provide a simple, drug-free way to improve heart blood flow and reduce complications after bypass surgery.
What could go wrong
This is a relatively small, early-stage study. Previous single-dose RIPC did not improve long-term outcomes, and the long-term version may also fail to show benefit.
