“…17) Lamping, et al reported that elevation of coronary artery perfusion pressure for more than one minute resulted in an increased vasoconstrictor response to serotonin that persisted for at least 2.5 hours. 18) High endogenous catecholamine levels during waking from anesthesia and hypoxic events 19,20) and high exogenous catecholamine levels, particularly dopamine, have been shown to precipitate CAS in susceptible patients. 21) Respiratory alkalosis due to hyperventilation, 17,22) hypothermia, 23) and underlying atherosclerotic disease, 24) are also reported to contribute to CAS.…”

SummaryCoronary artery spasm after coronary artery bypass surgery may result in life-threatening arrhythmias, circulatory collapse, or death. We report two cases of coronary artery spasm after coronary artery bypass surgery, one of which developed ventricular fibrillation requiring extracorporeal membrane oxygenation support. Both patients were discharged in good condition and are currently followed as outpatients. Unexpected sudden hemodynamic compromise could be due to coronary vasospasm, and this should be considered as one of the possible differential diagnoses. We were able to prevent the lethal consequences seen with coronary artery spasm by early diagnosis and management. (Int Heart J 2014; 55: 451-454)

“…However, the exact diagnosis of CAS can be reached only by coronary angiography. CAS may occur intraoperatively, 25) immediately after returning to the ICU, 26) upon awakening, 8,20) or shortly after extubation. 14) In previous studies, the majority of CAS cases have occurred within the first 24 hours after the operation.…”
