Post-stent blood flow test with nitroglycerin for multivessel patients
Part of Heart & circulation clinical trials.
This study tests a new way to measure blood flow after placing a stent, using a very thin wire with a camera. It helps doctors decide if the stent is working well without needing extra medication like adenosine—just a tiny dose of nitroglycerin. You may qualify if you have blockages in two or more heart arteries and are already scheduled for a stent procedure.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years old or older.
- You have significant blockages (stenosis) in at least two major heart arteries (the doctor sees 50% or more narrowing on an angiogram).
- You are scheduled to have a stent procedure (percutaneous coronary intervention, or PCI) in at least one of those blocked arteries.
- You are able to take a medication called adenosine (used during the procedure) and are not allergic to it.
- You are medically stable (not in the middle of a heart attack) and do not have a serious illness that would limit your life expectancy.

This study tests a new way to measure blood flow in narrowed arteries after you've had a stent placed for a heart attack. It may help doctors decide if you need more treatment to prevent future heart problems.
This study tests whether giving a drug called nicorandil directly into the heart artery just before placing a stent can help keep blood flow normal and reduce complications after the procedure.
This study checks how severely blocked a coronary artery is using measurements taken during a planned heart catheterization, to help guide whether and how to do a stent (PCI). It may help doctors choose the best treatment plan for people with about 70% or more narrowing.
This study looks at how well blood flows through the heart artery that was recently treated with a stent. It uses a non-invasive test to check the function of the artery, which may help guide future care.
This Phase 4 study tests a way to measure blood flow in heart arteries to help doctors choose the best stent plan. It may help improve safety and effectiveness for people having elective heart stent procedures for stable angina or certain heart attacks.
This study compares two ways of testing the small blood vessels in the heart to understand chest pain when no major blockages are found. It may help doctors learn more about why you have chest pain and how to treat it.
