Summary: Anesthesia-induced coronary vasospasm has been reported only rarely. We report a case, without previous cardiac history, in which immediately after anesthesia induction a marked ST elevation was noted on the EKG monitor. Premature ventricular contractions as well as nonsustained ventricular tachycardia were noted. These changes resolved immediately after nitroglycerin infusion and 75 mg of lidocaine were given. A coronary angiogram revealed normal comnary arteries and left ventriculogram. Eeonovine stimulation was not performed. The patient was discharged home on calcium entry blockers and nitrates. Exercise stress test two weeks after discharge was negative for ischemia. Induction of anesthesia triggering coronary spasm has been reported rarely, and to our knowledge never in the presence of angiographically normal coronary anatomy. Coronary vasospasm with typical EKG changes-namely, ST elevation and ventricular arrhythmias-has to be included as a possible complication of general anesthesia. Recognition of this syndrome allows prompt treatment and prevention of future episodes.
