  • Title: [A case of coronary vasospasm treated with stent placement].
    Author: Maeder M, Ammann P, Angehrn W, Rickli H.
    Journal: Z Kardiol; 2003 Feb; 92(2):182-7. PubMed ID: 12596080.
    Abstract:
    We report about a 49 year old woman with repeated chest pain at rest. During hyperventilation significant ST-segment elevation in leads V1-V5 appeared. Bicycle stress test did not provoke any ECG changes. Coronary angiography showed a significant stenosis of the left anterior descending coronary artery. Successful balloon angioplasty followed by stent implantation was performed. After an uneventful course of twelve months, hyperventilation could provoke neither chest pain nor ECG changes again without any antispastic medical treatment. Impact of fixed atherosclerotic lesions for the occurrence of coronary vasospasm, usefulness of hyperventilation as a non-invasive provocation test and therapy are discussed.
