Chest Pain Clinical Trial
Official title:
Reduced Myocardial Flow Reserve in Exertional Angina With Severe Aortic Stenosis and Normal Coronary Arteries: Insight From Prospective Observational Adenosine-stress Cardiac Magnetic Resonance Imaging Study
Exertional angina is common symptom in patients with severe aortic stenosis (AS) without
obstructive coronary artery disease (CAD). Although reduced myocardial flow reserve is one
of the proposed explanations for angina, little is known about the pathophysiology.
This study aimed that adenosine-stress cardiac magnetic resonance can be used for the
assessment of myocardial perfusion reserve and suggest the pathophysiology of development of
angina in patients with severe AS without obstructive CAD.
