STICH3C: Comparing CABG and PCI for Heart Conditions

The STICH3C study is looking at two ways to treat severe coronary artery disease (blocked heart arteries) and heart failure (when your heart can't pump enough blood). It compares revascularization by PCI (Percutaneous Coronary Intervention, a procedure to open blocked arteries with a balloon and stent) with revascularization by CABG (Coronary Artery Bypass Grafting, a surgery to create new paths for blood flow around blocked arteries). The study aims to see which treatment is better at reducing the risk of death, stroke, heart attack, needing another procedure, or being readmitted for heart failure over about 5 years. You might be able to join if you are over 18, have a reduced heart pumping ability (LVEF ≤40%), and have significant blockages in multiple heart arteries. The study is currently recruiting participants.

Study design
This is an international study involving 754 participants who will be randomly assigned to receive either PCI or CABG. It is an unblinded study, meaning both you and your doctors will know which treatment you receive.
What's involved
Initial treatment is expected within 2 weeks of joining, with some procedures possibly staged over 90 days. The study will follow you for about 5 years.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for a median of 5 years after their treatment to track their health outcomes.
