Using imaging to find blood clots in heart attack patients

Researchers are testing a new non-invasive imaging approach to identify blood clots in the coronary arteries of patients who have had a heart attack. Currently, doctors rely on invasive procedures (like cardiac catheterization) to determine whether a heart attack was caused by a blood clot or another problem. This study aims to see if advanced imaging can safely and accurately detect blood clots without needing an invasive procedure.

Many patients who have a heart attack actually have normal-looking coronary arteries on standard tests, which makes it hard for doctors to figure out what really caused the heart attack. Better imaging could help doctors quickly identify the true cause—such as a blood clot, artery tear, or other problems—so they can treat patients more effectively and avoid unnecessary invasive procedures.
