100.65 Abnormal Coronary Reactivity is Associated With Atrial Fibrillation Development: Is Atrial Fibrillation a Vascular Disease?

Coronary artery disease (CAD) risk factors are associated with atrial fibrillation (AF) and impaired endothelial function. We hypothesized that an abnormal coronary reactivity test (Abn-CRT) is associated with AF in patients with non-obstructive CAD. Three hundred patients with chest pain, non-
