NCT06895213
Evaluation of Plasma Renin Concentrations in Cardiac Surgery
The purpose of this research is to learn more about how renin (a blood test) is affected by cardiopulmonary bypass, the heart-lung machine used during open heart surgery. Renin is a protein that may be elevated in response to low blood pressure or situations where organs do not receive sufficient oxygen. Renin may potentially be used as an indicator for specific treatments aimed to increase the blood pressure. This study will evaluate blood samples for renin concentration throughout the course of open heart surgery.

Transfusion in Cardiac Valve Surgery
This prospective, randomized controlled study is aimed to figure out suitable transfusion threshold in patients undergoing cardiac valve surgery under cardiopulmonary bypass(CPB). Patients are randomly assigned to restrictive and liberal transfusion group and receive blood transfusion during and after surgery. Compare primary and secondary outcomes of two groups.
