Indications for Measuring Coronary Vascular Function as an Adjunct to Clinically Indicated Coronary Angiography

Condition	Invasive Diagnostic Management	Abbreviation
Current indications
Angina	No obstructive coronary disease	INOCA
Myocardial infarction	Infarction without culprit stenosis for which vasospastic angina is considered	MINOCA
Cardiac arrest	In certain scenarios (ventricular arrhythmias, resuscitated cardiac arrest) for which no clear cardiac cause can be found and the patient is stabilized with normal LV function, no obstructive CAD, and normal ECG findings	VSA
Future possibilities
Angina	Suspected obstructive CAD	Pre-PCI
	Post-PCI	Post-PCI
Heart failure	Preserved systolic function	HFpEF
	After cardiac transplantation
Myocardial infarction	Stratification of risk and prognosis	STEMI, NSTEMI
	No obstructive coronary disease	MINOCA

CAD = coronary artery disease; ECG = electrocardiographic; HFpEF = heart failure with preserved ejection fraction; INOCA = ischemia with no obstructive coronary artery disease; LV = left ventricular; MINOCA = myocardial infarction with no obstructive coronary disease; NSTEMI = non–ST-segment elevation myocardial infarction; PCI = percutaneous coronary intervention; STEMI = ST-segment elevation myocardial infarction; VSA = vasospastic angina.
