Intracoronary Acetylcholine Provocation Testing Among 921 Consecutive Caucasian Patients with Unobstructed Coronary Arteries

Clinical Usefulness, Angiographic Characteristics and Safety Evaluation of Intracoronary Acetylcholine Provocation Testing Among 921 Consecutive Caucasian Patients with Unobstructed Coronary Arteries

Clinical usefulness, angiographic characteristics, and safety evaluation of intracoronary acetylcholine provocation testing among 921 consecutive white patients with unobstructed coronary arteries.

BACKGROUND Coronary spasm can cause myocardial ischemia and angina in patients with and those without obstructive coronary artery disease. However, provocation tests using intracoronary acetylcholine administration are rarely performed in clinical routine in the United States and Europe. Thus, we assessed the clinical usefulness, angiographic characteristics, and safety of intracoronary acetylc...

Differential Incidence and Morphology of Spasm According to Coronary Arterial Location by Intracoronary Ergonovine Spasm Provocation Testing.

BACKGROUND We reported less provoked spasm in the left circumflex artery (LCX) by acetylcholine testing compared with the left anterior descending artery (LAD) and right coronary artery (RCA), so we investigated the clinical characteristics of provoked spasm in the LCX by ergonovine (ER) testing.Methods and Results:We retrospectively analyzed 1,185 consecutive cases of intracoronary ER testing ...
