Newly diagnosed obstructive CAD is relatively uncommon (16.5%) in ambulatory patients with stable angina without prior CAD, highlighting the potential role of microvascular or endothelial dysfunction.

Dirk Westermann Konstantinos Savvatis (2015) conducted a cross-sectional in stable angina pectoris (n=2,501). Pre-existing coronary artery disease vs. No previously documented coronary artery disease was evaluated on Significant obstructive CAD or progression of CAD documented by coronary angiography. Among patients with stable angina, obstructive CAD on angiography was found in 85% of those with known CAD compared to only 16.5% of those without previously documented CAD.
