Abstract
Myocardial ischaemia is an important cause of myocardial dysfunction in cardiac surgical patients in the postoperative period. It is essential that the signs of myocardial ischaemia are recognized and treated early before a vicious deteriorating spiral culminating in myocardial infarction occurs. The possible causes of myocardial ischaemia are: an imbalance of supply/demand balance resulting in subendocardial ischaemia; spasm of coronary artery or arterial conduit; thrombosis and/or occlusion of coronary graft or native coronary artery; and mechanical issues such as kinking of a coronary artery graft related to CABG surgery.
