"Swelling of the ER" = Myocardial ischemia from cessation of coronary blood flow describes a stepwise process of cellular injury. One of the first manifestations of cardiomyocyte injury is swelling of the cell and its organelles, which occurs as the intracellular accumulation of sodium leads to an alteration in the osmotic gradient. If blood flow is not restored, apoptosis eventually occurs.
