Heart showdown: stents vs. bypass surgery in diabetes patients

NCT ID NCT05831085

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study compares two advanced heart procedures—stenting guided by imaging and blood flow tests (PCI) versus bypass surgery (CABG)—in 1,500 people with diabetes and three blocked coronary arteries. The goal is to see which approach better prevents major events like death, heart attack, or stroke. Participants are randomly assigned to one procedure, and both groups also receive modern medications for heart health and diabetes.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Percutaneous coronary intervention (stenting) with imaging and physiology guidance, and coronary artery bypass grafting (bypass surgery)

What this could lead to

If this trial succeeds, it could show that modern stenting guided by advanced imaging is as good as or better than bypass surgery for people with diabetes and multiple blocked arteries, potentially offering a less invasive option.

What could go wrong

This is a large trial, but results may not apply to everyone with diabetes or heart disease. Both procedures carry risks like bleeding, infection, or heart attack, and the study is still recruiting, so outcomes are not yet known.
