Stable angina pectoris with no obstructive coronary artery disease is associated with increased risks of major adverse cardiovascular events.

Abstract

Patients with chest pain and no obstructive coronary artery disease (CAD) are considered at low risk for cardiovascular events but evidence supporting this is scarce. We investigated the prognostic implications of stable angina pectoris in relation to the presence and degree of CAD with no obstructive CAD in focus.
