Clinical trial for Coronary Artery Disease
Official title The Canadian CABG or PCI in Patients With Ischemic Cardiomyopathy Trial (STICH3C)
ClinicalTrials.gov ID: NCT05427370
What this study is testing
- What it's testing
- The study wants to see if surgery reduces death, stroke, heart attacks, urgent repeat procedures, or heart‑failure readmissions compared to the catheter procedure over about five years.
- Who it's for
- It looks for adults with blockages in several major heart arteries and weakened heart muscle who can safely receive either treatment.
- What's involved
- Participants will receive either the surgery or the catheter procedure, then have regular follow‑up visits and tests to track health outcomes and report how they feel.
- Time commitment
- The study lasts about five years, with scheduled visits and tests throughout that period.
- Time commitment: about 7 years

- Recent (\<4 weeks) ST-elevation MI;
- Concomitant severe valvular disease or other condition such as left ventricular aneurysm requiring surgical repair or replacement;
- Planned major concomitant surgical procedures (LAAO and AF ablation surgical procedures permitted);

Compensation & support
A stipend or payment for your time may be offered.
No amount is published here because ClinicalTrials.gov has no reliable field for payment or travel support. Ask the study team what's actually covered (payment for your time, travel, parking, or other study costs), and never join a trial for the compensation alone.
