ABSTRACT Coronary vasoreactivity testing is a key diagnostic procedure in patients with suspected coronary spasm and research procedures intended to assess the coronary endothelial function. We should mention that coronary spasm has been observed in > 40% of the patients with angina and non-obstructive coronary stenosis. Also, that its dedicated treatment has proven to reduce ischemic symptoms and improve these patients’ quality of life. This technical report elaborated by the Working Group on Intracoronary Diagnostic Techniques of the Interventional Cardiology Association of the Spanish Society of Cardiology (ACI-SEC) summarizes the indications, preparation, performance, and interpretation of the vasoreactivity testing performed by intracoronary infusion of acetylcholine.
