 A coronary artery bypass operation was scheduled for a 75-year-old man with 50% stenosis in the left main trunks, 99% in-stent restenosis in#6 of left anterior descending coronary artery and 75% stenosis in#15 of left circumflex coronary artery. As a preoperative test, an acetazolamide(ACZ)-stress scintigram test for evaluation of cerebral blood flow reserve was performed with continuous intravenous infusion of nicorandil. Strong back and chest pain with ST depression in I, aVL and V2-6 occurred 15 minutes later after intravenous injection of ACZ. Isosorbide dinitrate failed both to relieve the symptom or to reverse ST-T change. Intravenous morphine successfully relieved the symptom, but ST segment continued to depress for more than 90min. Thus, ACZ may be associated with worsening of myocardial ischemia.
