This protocol presents the acetylcholine rechallenge after nitroglycerine as an add-on procedure to spasm provocation testing. The purpose of this technique is to unmask co-existing microvascular spasm in patients with epicardial spasm and to assess the protective efficacy of nitroglycerine on a per-patient level to guide medical therapy.
