title: Perioperative myocardial infarction and changes in left ventricular performance related to coronary artery bypass graft surgery.
abstract: Recent advances in perioperative management and surgical technique have been associated with low operative mortality and a high incidence of symptomatic relief in patients undergoing coronary artery bypass graft (CABG) operations. The frequency and importance of perioperative myocardial infarction (MI) and immediate as well as long-term changes in left ventricular (LV) performance are factors of considerable current interest in any critical analysis of the effectiveness of CABG surgery. The present review describes the effects of patient selection, anesthetic techniques, and newer methods of myocardial protection as they relate to perioperative MI and LV performance. In addition, newer tests useful in the diagnosis of perioperative MI are discussed. The application of noninvasive techniques for the serial determination of LV performance and myocardial perfusion in CABG operations is also described.
