Comparison of serum cardiac specific biomarker release after non-cardiac thoracic surgery.

Background: The detection of postoperative myocardial infarction can be difficult in patients after lung surgery. The aim of this study was to verify the clinical significance of elevated Troponin I (cTnI), N-terminal pro-natriuretic peptide (NT-pro-BNP), lactate dehydrogenase (LDH), creatine kinase (CK), and CK-MB in the perioperative course.

Methods: Between 2007 and 2010, 64 patients (36 men, 28 women) were includeded in this prospective study and underwent thoracotomy and wedge lung resection (n = 20, group I), lobectomy/bilobectomy (n = 24, group II), and pneumonectomy (n = 20, group III).
