Why the study?
Does comprehensive invasive assessment provide diagnostic information affecting treatment and outcomes in patients with angina in the absence of obstructive coronary artery disease?
Does comprehensive invasive assessment provide diagnostic information affecting treatment and outcomes in patients with angina in the absence of obstructive coronary artery disease?
Comprehensive invasive assessment during coronary angiography in patients with angina and no obstructive CAD is safe and yields actionable diagnostic information.

May inform management of angina without obstructive CAD; leaves open confirmation of outcome benefit in randomized trials.
The majority of patients with angina in the absence of obstructive coronary artery disease have occult coronary abnormalities. A comprehensive invasive assessment of these patients at the time of coronary angiography can be performed safely and provides important diagnostic information that may affect treatment and outcomes.
