Why the study?
Do the duration of cardiopulmonary bypass and the magnitude of postoperative CK-MB release affect future myocardial function in patients undergoing coronary surgery?
Population
42 patients who underwent coronary surgery (21 evaluated at 18 months, 21 evaluated at 1 year)
Design
Cohort
Follow-up
12 to 18 months

Successful revascularization may preserve long-term myocardial function regardless of bypass duration or CK-MB release; leaves open randomized confirmation.
Do the duration of cardiopulmonary bypass and the magnitude of postoperative CK-MB release affect future myocardial function in patients undergoing coronary surgery?
Extended cardiopulmonary bypass times and postoperative CK-MB elevations do not adversely affect long-term myocardial function provided coronary revascularization is successful.
