Myocardial Ischemia: The Best Timing for Engaging CPB for Revascularization

Editors Note: Having been in the field for awhile, and being an STS data coordinator, the timing of surgery for patients suffering from an acute evolving myocardial infarction (AEMI) has always intrigued me. The STS data form is very specific in tracking these intervals, and I am naturally curious as to what the impact on […]

Myocardial Ischemia v.1

Myocardial Ischemia Prevention and treatment of perioperative myocardial ischemia is a primary consideration.  Two consistent factors associated with the pathogenesis of myocardial ischemia are inadequate oxygen supply to the myocardium due to localized coronary lesions, and excessive oxygen demand due to increased hemodynamic workload associated with increased heart rate, blood pressure, or adrenergic stimulation of […]
