Angiopoietin and Adverse Outcomes in Cardiac Surgery

Cardiac surgery and cardiopulmonary bypass can lead to systemic organ failure trough excess inflammation and endothelial injury. The angiopoietin family represented by angiopoietin 1 and 2 can reflect endothelial injury by a decrease in angiopoietin 1 and an increase in angiopoietin 2. The investigators hypothesized that angiopoietin dysregulation could reflect organ failure related to cardiac surgery. The purpose of this project is to assess the association between angiopoietin dysregulation and adverse outcomes on cardiac surgery.
