Question 1

what is ischemia?

Accepted Answer

Lack of blood flow: Ischemia is a lack of blood flow so that that the organ or extremity is not recieving an adequate amount of oxygen.

Question 2

how risky is ischemia?

Accepted Answer

Depends: It depends on how severe it is and which organ is ischemic. For instance it would be more serious to have ischemia to the heart or brain than to your foot.

Question 3

what is inferior ischemia?

Accepted Answer

Inferior WALL??: Could this be inferior wall ischemia?  If so, this refers to the inferior wall of the heart, i.e. Location (bottom) of the ischemia.  Ischemia indicates a lack of blood and therefore oxygen & nutrients to any part of the body, in this case the bottom of the heart.

Question 4

what is interval ischemia?

Accepted Answer

: With the limitations of having no clinical context and words being taken out of a report would read as ischemia or lack of blood supply that has developed over a time interval, most commonly seen in evolving strokes.

Question 5

what is reversible ischemia?

Accepted Answer

Poor blood flow: When arteries are narrowed, not enough oxygen gets to the tissue.
This is worse when exercising a muscle ( or heart muscle), becuause its oxygen requirement are increased. At  rest it might not be as much of an issue , because oxygen requirements are less.

Question 6

what are symptoms of ischemia?

Accepted Answer

Depends: It depends on the part of the body that is not getting enough blood and oxygen. If it is the heart you could get chest pain. If it's a leg, leg pain. If it's the brain you could get a stroke.

Question 7

what generally causes ischemia?

Accepted Answer

Atherosclerosis: The formation of the atheromatous plaque, which comprises of a lipid laden core covered by a fibrous cap, is the pathophysiological hallmark of atherosclerosis. It is the acute rupture of such plaques that results in a clot (thrombus) that results in ischemia, which simply means inadequate blood flow.

Question 8

what symptoms suggest ischemia?

Accepted Answer

Depends: Depends what part of body is affected: heart= chest pain, heart attack; leg=painful cold leg; brain=stroke; gut=abdominal pain, bloody diarrhea; kidney=high blood pressure.

Question 9

what is anterior wall ischemia?

Accepted Answer

Heart: This is likely a finding on a cardiac stress test describing diminished or slowed blood flow to the anterior portion of the wall of the left ventricle of the heart. Needs to be placed in context with the patient's other test findings as to its significance.

Question 10

what is an explanation of ischemia?

Accepted Answer

Lack of enuff blood: "ischemia" = the normal tissue (eg heart, brain, intestine) is not receiving sufficient blood flow to supply the oxygen needed for the tissue's normal metabolic activity. For instance, ischemic heart muscle cannot contract normally. Cardiac ischemia is documented on a stress test, by using signs like EKG changes, flaccid heart muscle squeezing,  or lack of uptake of nuclear tracer by heart muscle.
