Clinical Characteristics, Sex Differences, and Outcomes in Patients With Normal or Near‐Normal Coronary Arteries, Non‐Obstructive or Obstructive Coronary Artery Disease

Abstract

Many (44.5%) patients undergoing nonemergent invasive coronary angiography have NNCAs or nonobstructive CAD despite high pretest risk, including ischemia and troponin elevation. Although women had more NNCAs or nonobstructive CAD, there were no differences in event rates by sex. Patients with NNCAs and nonobstructive CAD had very low event rates.
