Protein Kinase N1 Level in Patients Undergoing Cardiac Surgery

Acute kidney injury (AKI) is one of the most frequent major complications in patients undergoing cardiac surgery. CSA-AKI is independently related to increased perioperative mortality, increased hospital and ICU length of stay as well as heath care expenditure. Identification of relevant biomarkers may lead to early diagnosis and improve patient outcomes and health care costs. The pathophysiology of CSA-AKI is complex and ischemia-reperfusion injury is one of the important factors. Recently, it has been shown that Protein kinase N1 (PKN1) is associated with ischemia-reperfusion injury. In this study, relationship between PKN1 with the risk of CSA-AKI was analyzed and the predictive value of elevated level of PKN1 for early prediction of CSA-AKI was further evaluated.
