ClinConnect Summary

The B-MORE trial is studying a new way to help doctors understand how well the heart is getting enough oxygen in patients who may have a condition called coronary artery stenosis, which means their heart arteries are narrowed. The goal is to find a reliable marker that shows how well the heart is responding to oxygen needs. The trial is currently looking for participants aged 18 and older, whether they are healthy or have coronary artery disease, as long as they don't have certain medical conditions that could interfere with the study.

If you join this trial, you'll undergo some tests to check your heart's oxygen levels. It's important to note that there are some restrictions: you shouldn't have any heart devices like pacemakers or be pregnant, and you must avoid caffeine and nicotine before the exam. This study aims to provide better tools for diagnosing heart issues, which could ultimately help improve treatment options for patients with heart problems.
