  • Title: [Coronary artery spasm as a cause of perioperative myocardial infarction and stunned myocardium].
    Author: Yanagawa T, Fujiwara M, Takakuwa R, Mizoguchi H, Komeichi Y, Kawamura J, Odashiro M.
    Journal: Masui; 1995 Nov; 44(11):1550-4. PubMed ID: 8544296.
    Abstract:
    We report a male patient who had recurrent coronary artery spasm on withdrawal from cardiopulmonary bypass, which led to myocardial infarction and stunned myocardium. The spasm responded to conventional medication. Transesophageal echocardiogram showed no remarkable asynergy during the operation. However, MB fraction of creatine kinase was 132 IU.l-1 and electrocardiogram showed new Q waves. After stopping intravenous catecholamines, hypokinesis of the anteroseptal segment appeared in the echocardiogram. Spotty myocardial necrosis and stunned myocardium might have resulted from recurrent coronary artery spasm.
