The principal objective to this randomized trial is to compare the efficacy of two strategies of intra-operative hemodynamic management during cardiopulmonary bypass among patients undergoing primary elective coronary artery bypass graft (CABG) surgery in preventing peri-operative cardiac, cognitive and neurologic morbidity and mortality and post-operative deterioration in the patient's quality of life as measured by the seven domains of SF-36 Health Survey (bodily pain, health perceptions, energy, and mental, physical, social and role function).

Condition Intervention
Coronary Artery Bypass Graft Surgery Patients Procedure: Mean arterial pressure during cardiopulmonary bypass 80 mmHg vs. customized

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Factorial Assignment
Masking: Single
Primary Purpose: Prevention

Primary Outcome Measures:
  • Quality of life
  • Cardiac morbidity
  • Neurologic morbidity
  • Mortality
  • Neurocognitive deterioration

Secondary Outcome Measures:
  • • To evaluate the prognostic importance of severe atheromatous disease of the descending aorta as found on transesophageal echocardiography (TEE) as a predictor of neurologic events.
  • • To correlate TEE and epiaortic scanning for aortic atheroma with transthoracic echocardiography (TTE) in order to develop a non-invasive screening tool.
  • • To assess the clinical significance of persistent post-operative depression as measured by the CES-D by using a structured clinical interview and to evaluate the relationship between pre-operative depression and the occurrence of cardiac, neurologic a
  • • To provide data on the mechanism of perioperative neurologic and cognitive complications in order to design other specific intervention to reduce postoperative morbidity.

Estimated Enrollment: 412
Study Start Date: December 1996
Estimated Study Completion Date: December 1999
Detailed Description:
In one group, mean arterial pressure (MAP) was 65 mmHg. In the other, the MAP target was determined by the patients usual preoperative MAP. Thus, the trial will evaluate whether tailoring the MAP target for the period of cardiopulmonary bypass to within 10 mmHg of the patients usual MAP, but < 90 mmHg (and thus achieving pressures during bypass within the patients usual autoregulatory range) reduces major neurologic and cardiac morbidity and mortality, as well as cognitive complications, thereby improving post-operative quality of life.
