Multivessel Coronary Function Testing Increases Diagnostic Yield in Patients With Angina and Nonobstructive Coronary Arteries
Authors' conclusion
Multivessel CFT resulted in an increased diagnostic yield in patients with ANOCA compared with single-vessel testing.
Study context

- Patients with suspected angina and nonobstructive coronary arteries (ANOCA)
- Participants
- 80 patients228 vessels
- Comparison
- Multivessel vs single-vessel invasive coronary function testing
- Outcome
- Diagnostic yield (coronary vasomotor dysfunction)

- 15 (18.8%)
- 3-vessel CMD
- 8 (10%)
CMD by coronary territory
