Subendocardial Blood Flow Determinants

Editor’s Note: Subendocardial Blood Flow Determinants While subendocardial and sub-epicardial layers have the same determinants for blood flow, subendocardial layers are at greater risk from ischemia and infarction.  The deeper subendocardium is subjected to greater wall tension which then expresses as a metabolic requirement 10-20% greater than the more superficial epicardium. Higher oxygen demand and […]
