Vasospastic angina is a clinical and physio-pathological entity, which has been documented for many years, but its diagnosis is under-estimated despite the fact that though inadequately considered and investigated. This condition is potentially serious and can sometimes trigger severe arrhythmia resulting in ventricular fibrillation and sudden death. This pathology has a higher incidence in Asia, where it is, therefore, better documented with provocative testing being carried out more frequently, while in France, these tests are not sufficiently performed probably due to the fact that they often produce negative findings. Provocative tests with Ergonovine injection should be performed via intra-coronary to improve its sensibility. Should this test become more sensitive and more routinely performed, this condition, which often responds well to medical treatment, could regain appropriate recognition as a coronary disease.
