• Ischemia with non-obstructive coronary arteries (INOCA) encompasses a breadth of structural and functional abnormalities of the coronary circulation causing ischemia (and angina) despite the lack of obstructive epicardial atheroma. • Several diagnostic techniques are available, including invasive and non-invasive ones. At present, invasive functional assessment, using both pressure wire and vasoreactivity tests and also termed #FullPhysiology, is the only one allowing comprehensive evaluation of the pathophysiological mechanisms of INOCA. • Leveraging #FullPhysiology, a stratified medical therapy can be implemented, which can mitigate symptoms and positively affect quality of life in patients with INOCA. Ischemia with non-obstructive coronary arteries (INOCA) is an increasingly recognized entity. It encompasses different pathophysiological subtypes (i.e., endotypes), including coronary microvascular dysfunction (CMD), vasospastic angina (VSA) and mixed entities resulting from the variable combination of both. Diagnosing INOCA and precisely characterizing the endotype allows for accurate medical treatment and has proven prognostic implications. A breadth of diagnostic technique is available, ranging from non-invasive approaches to invasive coronary angiography adjuvated by functional assessment and provocative tests. This review summarizes the strength and limitations of these methodologies and provides the rationale for the routine referral for invasive angiography and functional assessment in this subset of patients.
