Safety Evaluation of Routine Intracoronary Acetylcholine Infusion in Patients Undergoing a First Diagnostic Coronary Angiogram

Abstract

Intracoronary acetylcholine infusion is safe, but may lead to serious adverse reactions. Care should be taken especially in patients younger than 60 years of age. Routine use of acetylcholine infusion can thus only be justified if it has important prognostic significance. This has to be proven further in large prospective studies.
