Guidance method for opening heart blockages with stents
Part of Heart & circulation clinical trials.
This study compares two ways of deciding how completely to open blocked heart arteries using drug-eluting stents. It aims to see which guidance approach improves results and safety for people with coronary artery disease who need a PCI (heart catheter procedure).
Summary written for real people, not researchers, by Clin2.
Who can take part
- You’re age 19 or older and have coronary artery disease with chest pain or proof of reduced blood flow to the heart
- Your coronary artery blockages are in major vessels and are about 50% to 90% narrowed (and the vessel is at least 2.25 mm wide)
- You must be able to sign the consent form (or your guardian can) and agree to follow-up visits and study procedures
- You should not have coronary artery bypass surgery in the past
- You likely should not have pregnancy/breast-feeding, and you must be able to take required blood-thinning medicines (aspirin and another antiplatelet like clopidogrel/prasugrel/ticagrelor)
- You should not have certain situations that make testing or the procedure unsafe, like severe vessel twisting that prevents a pressure test, left heart pumping being too weak (ejection fraction under 35%), or a life expectancy under 1 year

This study looks at a new way to place stents in blocked heart arteries that are at a branching point. It aims to improve blood flow and reduce the risk of the blockage coming back, compared to standard methods.
This trial compares two treatments for new blockages in heart arteries: a drug-coated balloon (a tiny balloon that delivers medicine) versus a drug-eluting stent (a small mesh tube that releases medicine). The study hopes to see which approach keeps the artery open longer and is safer over time.
This study looks at whether opening blocked heart arteries with a stent (a PCI procedure) works better than staying on heart medicines for people with weakened pumping function and certain types of heart failure. It may help patients by testing which approach best improves outcomes over time.
This study compares two ways to open blocked heart arteries: one uses a balloon coated with medicine, and the other uses a small mesh tube (stent) that releases medicine. The goal is to see which works better for people with chest pain or a recent heart attack.
This study tests whether opening blocked heart arteries with stents can improve heart function in people with heart failure caused by coronary artery disease. It may be an option if your heart is weak and you have multiple blockages but no recent heart attack or dangerous rhythm.
This trial compares two ways to open blocked heart arteries: a drug-coated balloon (a small balloon that releases medicine) versus a drug-eluting stent (a tiny mesh tube that also releases medicine). It aims to find which option works better for people with relatively simple blockages.
