The cardiomyocytes in the ''subendocardial'' layers are especcially vulnerable for a decreased perfusion. Subendocardial ischemia manifests as ST depression and is usually reversible. In a myocardial infarction ''transmural ischemia'' develops. | The cardiomyocytes in the ''subendocardial'' layers are especcially vulnerable for a decreased perfusion.
