Why the study?
Do perioperative changes in catecholamines correlate with increased post-operative troponin levels in cardiac risk patients undergoing non-cardiac surgery?
Population
28 patients at risk for or with definite coronary artery disease undergoing non-cardiac surgery

May link catecholamines to perioperative injury; hypothesis-generating and should not yet change practice.
Do perioperative changes in catecholamines correlate with increased post-operative troponin levels in cardiac risk patients undergoing non-cardiac surgery?
Increased post-operative release of catecholamines correlates with high post-operative serum levels of troponins in cardiac risk patients undergoing non-cardiac surgery, suggesting a potential mechanism for perioperative myocardial injury.
Sametz et al. (1999) studied this question.
