The OCT2ACT study is investigating why advanced imaging tools—called optical coherence tomography (OCT) and intravascular ultrasound (IVUS)—are underused during complex heart procedures, even though medical guidelines now strongly recommend them. Researchers will follow 1,000 patients receiving treatment for coronary artery disease to understand the real-world barriers doctors face and how these imaging tools actually influence procedure planning and outcomes.
Recent medical evidence shows that using advanced imaging during complex heart procedures can reduce serious complications and deaths compared to standard imaging alone. However, many doctors don't use these tools in daily practice for reasons that haven't been well studied—such as cost, time, or lack of training. This study aims to identify those barriers now that these tools are officially recommended and more affordable, so that more patients can benefit from them.

If you qualify, you will be observed during your scheduled heart procedure and your care team will document whether advanced imaging (OCT or IVUS) is used, why it is or isn't used, and how it influences your treatment plan. You will be enrolled into one of three groups based on your actual clinical care: those receiving advanced imaging as recommended, those not receiving it despite guidelines, or those receiving it for other reasons. Your medical records will be reviewed and collected for research purposes, but this study does not require additional visits or procedures beyond your standard care.
