• National registry data indicate that approximately 60% of patients referred for invasive coronary angiography (ICA) have normal coronary arteries (NCA) or nonobstructive coronary artery disease (CAD) (1). [...]this study shows that despite a high prevalence of normal coronary arteries or nonobstructive CAD, the rate of appropriateness of referral for nonemergent coronary angiography was very high at 99%. Imaging advances will likely play a significant role, including noninvasive coronary anatomic evaluation by computed tomography angiography and improved perfusion assessment with positron emission tomography and cardiac magnetic resonance. Future research should also determine the role of microvascular and endothelial dysfunction in patients with abnormal stress tests or chest pain syndromes who are subsequently shown to have NCA or nonobstructive CAD on ICA. 1 M.R.
