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.
Ischaemia is the lack of blood supply to a tissue which start anaerobic respiratory mechanisms. Infarction is cell death through apoptosis resulting from prolonged or severe ischaemia. Clinicaly myocardial infarction will be more painful and is unrelieved by rest. On ECG infarction will reult in ST segment elevation where ischaemia will result in ST segment depresion (unless it is a posterior MI!). In MI there will also be raised biochemical markers hours later such as creatine kinase and troponin.
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.
ischaemia
Acute Myocardial Infarction (AMI).
Ischaemia
It's when the wall between the left and right ventricles of the heart has an infarction.
watershed infarction cerebral infarction in a watershed area during a time of prolonged systemic hypotension
The abbreviation for myocardial infarction is M.I.
It's when the wall between the left and right ventricles of the heart has an infarction.

The term most often used is infarction for a complete lack of blood flow to a particular organ (most often used when referring to a muscle such as the heart or skeletal muscle), or ischaemia for severely reduced blood flow. If you are simply referring to a reduced amount of oxygen then tissue hypoxia may apply.
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.
