Postoperative Troponin in Renal Dysfunction After Cardiac Surgery

Elevated level of troponin is frequently observed among patients with renal dysfunction. Increase in troponin after cardiac surgery may predict postoperative outcome in cardiac surgery patients. However, the relationship between the increased troponin and outcome after cardiac surgery has not been fully elucidated in patients with renal dysfunction.

This is a retrospective observational study to evaluate the prognostic value of postoperative troponin in patients with renal dysfunction undergoing cardiac surgery. Electrical medical records of patients who underwent cardiac surgery between 2004 and 2015 will be assessed. Perioperative laboratory data including troponin and glomerular filtration rate, type of surgery, and outcome variables including mortality will be analysed to determine the prognostic value of postoperative value of postoperative troponin in patients with renal dysfunction undergoing cardiac surgery.
