Intracoronary acetylcholine provocation testing
Clinical usefulness, angiographic characteristics, and safety evaluationsafety
Intracoronary acetylcholine provocation testing is a safe and useful method to evaluate coronary vasomotor function and identify epicardial and microvascular spasm in patients with unobstructed coronary arteries.
Epicardial and microvascular spasm are frequently found in white patients with unobstructed coronary arteries. Epicardial spasm is most often diffuse and located in the distal coronary segments. The intracoronary acetylcholine provocation test is a safe technique to assess coronary vasomotor function.
