Serial prognostic capabilities of electrocardiographic indices of infarcted and hibernating myocardium in predicting short- and long-term outcome following coronary artery bypass surgery.
The present study was performed to test the hypothesis that patients with a large amount of ischemic (hibernating) myocardium are most likely to develop a perioperative myocardial infarction undergoing coronary artery bypass grafting (CABG). Furthermore, we evaluated the Selvester QRS scoring system as a postoperative prognostic tool. A relationship between a high amount of hibernating myocardium determined by ventriculographic and electrocardiographic investigations and an increased risk of perioperative myocardial infarction was found. The Selvester QRS scoring system used in diagnosing and prognosing after acute myocardial infarction was proven valid in predicting prognosis after CABG as well.
