1. Does anyone use a dictionary or Google anymore? Ischemia means lack of oxygen to tissue, this precedes infarction which is death of the tissue due to lack of oxygen. Ischemia in the brain is a stroke, ischemia of the heart muscle is a heart attack etc.
2. Ischemia= lack of/or no oxygen to the heart/area of the heart Necrosis= Dead tissue to the heart area So Someone had a heart attack because there wasnt enough oxygen to the area, which in the end cause an area of the heart to die, which is bad
3. Ischemia is not a stroke it is a lack of oxygen (carried by the blood) to muscle.
4. Ischemia: Inadequate blood supply (circulation) to a local area due to blockage of the blood vessels to the area. http://www.medterms.com/script/main/art.asp?articlekey=4052
