PCI Revascularization Strategies for Coronary Artery Disease
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores two methods for performing a heart procedure called PCI (Percutaneous Coronary Intervention), which opens blocked arteries. One method combines two tests, FFR (Fractional Flow Reserve) and OCT (Optical Coherence Tomography), to guide the procedure, while the other uses FFR alone. The researchers aim to determine if using both tests leads to better outcomes for individuals with multiple blocked heart arteries. Suitable candidates have been diagnosed with at least two new blockages in different heart arteries that could be treated with PCI. As an unphased trial, this study allows patients to contribute to innovative research that could enhance heart procedures for future patients.
Do I need to stop my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. Please consult with the trial coordinators for more details.
What prior data suggests that this PCI revascularization strategy is safe for patients with coronary artery disease?
Previous studies have shown that PCI, a procedure to open blocked heart arteries, using FFR, a method to measure blood flow, is safe. Patients who underwent PCI guided by FFR had a lower risk of death from any cause, indicating it is generally well-tolerated.
However, less information exists about using OCT, a special imaging technique, with FFR. OCT provides clearer views inside arteries, but long-term safety data is limited. While FFR-guided procedures are considered safe, researchers continue to study OCT to ensure it does not introduce additional risks.12345Why are researchers excited about this trial?
Researchers are excited about these treatments for coronary artery disease because they refine how we decide on PCI revascularization strategies. Most current treatments for this condition use angiography alone to assess how blocked an artery is. However, the new approaches include either FFR (Fractional Flow Reserve) assessment alone or a combination of FFR and OCT (Optical Coherence Tomography) assessments. FFR helps measure blood pressure differences across a coronary artery to gauge the significance of a blockage, while OCT offers high-resolution images to evaluate the artery's condition. This combination could lead to more precise decision-making and potentially better outcomes for patients by tailoring treatment to the specific characteristics of their coronary artery disease.
What evidence suggests that this trial's PCI revascularization strategies could be effective for coronary artery disease?
This trial will compare two PCI revascularization strategies for coronary artery disease. One arm will use a strategy based on both FFR and OCT assessments. Research has shown that using both FFR and OCT during PCI can improve treatment outcomes, as FFR measures blood flow and OCT provides detailed images of the arteries. Studies have found that this combined approach is generally safe and aids doctors in making better decisions about restoring blood flow.
The other arm will use a PCI revascularization strategy based on FFR assessment alone, with a sham OCT. Using FFR alone in PCI has been linked to a lower risk of death in patients with coronary artery disease. Adding OCT provides more detailed information about the artery's condition, potentially leading to better results. Together, these methods aim to make PCI procedures more precise and effective.678910Who Is on the Research Team?

Are You a Good Fit for This Trial?
This trial is for individuals aged 30-80 with multiple vessel coronary artery disease who are undergoing PCI. They must have at least two new blockages in different arteries suitable for PCI, as determined by a heart team. The blockages should be significant but the blood flow through them must still be normal.Inclusion Criteria

Trial Overview
The COMBINE-INTERVENE Trial is testing if using both FFR (a pressure wire test) and OCT (an imaging test) to guide where stents should go during PCI is better than just using FFR alone in patients with multiple blocked arteries.
