Why the study?
Can the CK-MB/total CK ratio differentiate skeletal muscle damage from peri-operative myocardial infarction following non-cardiac thoracic surgery?
Population
23 patients undergoing thoracotomy, including 14 for serum analysis and 9 for muscle sample analysis.
Comparison
Thoracotomy (non-cardiac thoracic surgery) vs Historical findings after cardiopulmonary bypass…

Low post-thoracotomy CK-MB/CK ratio may reflect skeletal injury rather than MI; leaves open whether this threshold reliably excludes perioperative infarction in practice.
Can the CK-MB/total CK ratio differentiate skeletal muscle damage from peri-operative myocardial infarction following non-cardiac thoracic surgery?
The CK-MB/total CK ratio at 24 hours post-operation can help diagnose peri-operative myocardial infarction in non-cardiac thoracic surgery, with a ratio <2.2% indicating skeletal muscle damage rather than MI.
