Using carbon dioxide to check heart blood flow
Part of Heart & circulation clinical trials.
This trial uses a special MRI technique with carbon dioxide to check how well blood flows to your heart muscle. It might help doctors better understand blockages in the heart arteries.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be at least 18 years old.
- You have known or suspected coronary artery disease (blocked heart arteries).
- A recent heart scan (SPECT/PET) showed mild to moderate reduced blood flow.
- You are able to have an MRI (no metal implants like pacemakers, no severe claustrophobia, and can lie flat for 60-90 minutes).
- You have not had a prior heart attack.
- You are not pregnant or nursing, and do not have an intrauterine device (IUD).
- You have no history of asthma, significant heart, lung, kidney, or liver disease, or allergy to gadolinium contrast.

This study uses a needle-free device to measure oxygen levels in the heart muscle of healthy adults. Your participation helps researchers better understand normal heart oxygen levels, which can improve future heart care.
This study tests a special heart scan that measures blood flow to the heart muscle. It may help doctors decide if your heart blockages need treatment or if medication is enough.
This trial tests whether using a special heart CT scan (with blood-flow analysis) can better guide care for people who come to the ER with chest pain and are at medium risk for heart problems. It might help avoid unnecessary procedures and find real blockages sooner.
This trial uses a heart scan (PET/CT) to better estimate blood flow in people with long-term coronary artery disease. It aims to help doctors choose the best treatment strategy and decide who may need more invasive testing or procedures.
This study compares two types of radioactive tracers used during heart PET scans to see if one is better at detecting blocked arteries. Participation involves receiving one of the tracers during your routine scan and may help improve heart disease diagnosis.
This study looks at specific blood-flow and heart-rhythm signals during an exercise test to find signs of reduced blood flow to the heart. It may help doctors spot heart problems sooner and decide who needs more care.
