[Vasospastic angina: An under-diagnosed pathology]. Ann Cardiol Angeiol (Paris). 2019 Sep 18;: Authors: Benamer H, Saighi Bouaouina M, Masri A, Sarkis G, El Beze N, Millien V Abstract The clinical and physiopathological clinical entity known as spastic angina or variant angina has been long documented. It remains, however, an under-estimated condition, which is insufficiently diagnosed and explored. This pathology is associated with severe complications such as heart rhythm disorders, which may potentially result in ventricular fibrillation and cause sudden death. In Japan, this condition occurs more frequently and is better documented. Stimulation tests are also carried out more often and have a higher positivity rate than in France where vasospastic angina is less frequently reported and where provocation tests are associated with negative results and are, consequently, performed less often. In order to improve the detection of this pathology, its potential presence should be explored in patients with rest angina who experience chest pain in the second half of the night and also in instances of acute coronary syndrome with sudden death and no angiographically visible coronary artery disease. The diagnosis should be confirmed by means of ergonovine provocation tests. In order to enhance the sensitivity of these tests without increasing the risk of complications, injection of ergonovine should be preferably carried out via the intrac...
