Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Multivessel functional angiography
- Qualified study personnel will complete coronary physiology and vasoreactivity testing (with intracoronary acetylcholine) to assess the coronary microcirculation and propensity for coronary vasospasm. Vasoreactivity testing will include incremental doses of acetylcholine (20/50/100/200mcg into the left coronary system and 20/50/80mcg into the right coronary system, respectively)
- All 3 major epicardial coronary arteries (left anterior descending, left circumflex and right coronary artery) will be assessed.
- This intervention will occur in the cardiology catheterization lab and be delivered once during the study period.
- The intervention will take approximately 45 minutes to complete

Diagnosis / Prognosis
Comparator / control treatment
Single vessel functional angiography
- Qualified study personnel will complete coronary physiology and vasoreactivity testing (with intracoronary acetylcholine) to assess the coronary microcirculation and propensity for coronary vasospasm.
- Only 1 epicardial coronary artery (at the operator's discretion) will be assessed.
- This intervention will occur in the cardiology catheterization lab and be delivered once during the study period.
- The intervention will take approximately 30 minutes to complete
