About the study

This research aims to investigate whether symptoms of chest pain or shortness of breath among the study population are arising due to a heart problem, particularly any reduction of blood flow to the heart muscle from blockages in the coronary blood vessels or inflammation of the heart using cardiac magnetic resonance imaging that measures the amount of blood flow during a stress state meant to simulate vigorous exercise. At present, doctors use standard magnetic resonance imaging pictures of blood flow patterns to treat heart disease. The investigators want to study if detailed blood flow measurements, in addition to the standard blood flow pattern, could diagnose heart disease more accurately and allow more doctors to understand the severity of heart disease. Early research has demonstrated that detailed blood flow measurements may be more accurate in diagnosing heart disease in some patients, but doctors need more information to know how to use these measurements.
