==Subendendocardial Ischemia== | |||
Subendocardial ischemia is ischemia that is not transmural. It is mostly caused by demand ischemia where energy supply to cardiomyocytes is insufficient for the work force, e.g. during extreme hypertension, aortic valve stenosis, extreme left ventricular hypertension, anemia, atrial fibrillation with rapid ventricular response. | |||
On the ECG often diffuse ST depression is present. Cardiac enzymes (CK-MB, Troponine) may or may not be elevated depending on the severity. | |||
