in myocadial ischemia, pain radiate to jaw, neck,shoulder,arm wheras in aortic dissection pain radiate to back, between scapulae
there is differense between pulse rate of both arms and leg
depending on ecg changes

what is reversible vs irreversible ischemia in the brain
simply, Hypoxia is less oxygen supply to cell tissues, while the Ischemia is less blood supply to cell issues.
you can't you can't
Ischemia=decreased oxygen/nutrients Infarction=no blood flow to the area ischemia can leads to infarction. ischemia means, reduced of blood supply to specific organ. while, infarction refers to death tissue.
For the dissection of a cat , you will be needing a cat version while for the dissection of a pig you'll be needing a pig version.
A heart attack (myocardial infarction) is the result of a blockage in an artery which feeds the heart, so the heart becomes starved for oxygen.

Necrosis means that a cell or a group of cells die due to injury (heat, pressure etc), diseases (infections), or other pathological state. The term "infarction" essentially is synonymous with "ischemic necrosis" which means necrosis (cell death) from the lack of blood (ischemia). Ischemia can be caused by the occlusion of the arterial supply or venous drainage for a particular tissue.
necrosis is death of cells with underlying/ or death of cells that cause inflammation. necrosis has to have an underlying injury. ischemia is decreased blood supply to tissues/ cells due to obstruction/ constriction of vasculature - indeed, this is an injury, and can lead to necrosis of cells if not resolved quickly! Note that apoptosis is programmed cell death - i.e. nucleus control is involved, and there is no inflammation - it is clean cell death! this is awesome.
Angina is the very short term lack of blood flow to the heart with no tissue death. Myocardial infarction is the complete lack of oxygen to the heart muscle and the muscle tissue death.
