Primary Outcome Measures:
  • Number of participants of the major adverse cardiac events [ Time Frame: Stay in hospital ] [ Designated as safety issue: Yes ]
    The composite of major adverse cardiac events included acute myocardial infarction, cardiac arrest with successful resuscitation, low cardiac output syndrome/cardiogenic shock, arrhythmia and all-cause death.


Secondary Outcome Measures:
  • Mortality [ Time Frame: 30-day and 180-day after operation ] [ Designated as safety issue: No ]
  • Length of stay in intensive care unit and hospital [ Time Frame: Stay in intensive care unit and hospital ] [ Designated as safety issue: No ]
    Length of stay in intensive care unit and hospital

  • Number of patients of postoperative comlications [ Time Frame: Stay in hospital ] [ Designated as safety issue: No ]
    Postoperative complications included prolonged ventilation, requiring epinephrine, sepsis/infection, renal complications and reoperation.


Other Outcome Measures:
  • Left ventricular ejection fraction (LVEF) [ Time Frame: 24h after operation and before discharge ] [ Designated as safety issue: No ]
  • Creatine kinase myocardial bands (CKMB) [ Time Frame: 24 h and 48 h after operation ] [ Designated as safety issue: No ]

Detailed Description:

Cardiopulmonary bypass (CPB) is a necessary technique to maintain the circulation during cardiac surgery. But CPB itself is associated with a series of problems of organs, such as hyperglycemia induced by neuroendocrine stress. The research showed that hyperglycemia induced by stress would cause a worsened hospital outcome for patients undergoing cardiac surgery. Intraoperative and postoperative glucose control is beneficial for patients.

It has been for more than 40 year since the first application of glucose - insulin - potassium (GIK) in cardiac surgery but the clinical application of GIK shows controvertial results. The beginning time of application, and the ratio of glucose and insulin may be the key cause for the difference. In our pilot trial of 40 valve replacement cases, the investigators found that GIK with high insulin dose showed beneficial effects during heart surgery. Therefore, the investigators are planning to continue to use the GIK with high insulin dose for more heart surgery patients and estimate whether GIK may have cardioprotective effects on patients undergoing heart surgery.
