Key result
The incidence of postoperative regional wall motion abnormalities increased with higher CK-MB levels (up to 55% without Q waves), with severity of dysfunction similar to those with new Q waves (p=NS).
Why the study?
Does the severity of regional wall motion abnormalities and left ventricular dysfunction differ between non-Q wave and Q wave perioperative myocardial infarction after CABG?

p-value: p=NS
Force et al. (1985) conducted an observational in Coronary artery bypass surgery (n=65). Coronary artery bypass surgery (stratified by postoperative CK-MB levels and Q waves) was evaluated on Incidence of postoperative regional wall motion abnormalities (RWMAs) (p=NS). The incidence of postoperative regional wall motion abnormalities increased with higher CK-MB levels (up to 55% without Q waves), with severity of dysfunction similar to those with new Q waves (p=NS).
