How Does The Body Change To Try To Compensate For Coronary Ischemia
How many difference can there be in RV-EDV between two Cardiac MRI's when there is no change in heart size, how accurate is the MRI machine?
Machine is accurate: however each machine has its own characteristics. Each a little different than the other. Also each person doing the measurements will be a little different than the other person. Different yes. How different is the real question. The measurements should still be acceptable with a variation that is acceptable to your doctors. ...Read more
Ischemia is a symptom in which a person does not have enough blood supply to a part of the body, making that part of the body "ischemic". For example, in a heart attack, a coronary artery is blocked so blood cannot get to the heart muscle beyond the blockage point. The heart muscle lacking ...Read more
Coronary ischemia: The body will try to limit activity in order to decrease ischemia, so some people will feel fatigue or shortness of breath. Also often people have angina or chest pain with activity which limits activity. On the local level small vessels called collateral vessels can grow to bypass the blockage. ...Read moreSee 1 more doctor answer
Good question: Through biochemical mechanisms stimulated by decreased blood flow to areas of the heart, small collateral arteries can form as branches of the larger coronary arteries in order to maintain as much blood supply to the heart as possible. These collateral arteries can often prevent permanent damage to the heart, but they rarely normalize the blood flow necessary for normal heart function. ...Read moreSee 1 more doctor answer
Blood flow limited: It means that the heart muscle is not getting enough blood flow to meet its metabolic demands to carry out the required activities. This usually connotes a narrowing ("blockage") in one of the major coronary arteries that supplies heart muscle with blood, and hence oxygen. ...Read moreSee 1 more doctor answer
Not necessarily: Angina is a symptom of chest discomfort. Heart cells die only when the blood supply to the heart is stopped for at least 20 minutes. Angina may occur with no stoppage of blood to the heart, or it may occur in the presence of a damaging heart attack, known as myocardial infarction. ...Read moreSee 1 more doctor answer
By blocking the flow: In young, healthy individuals the inner lining of the blood vessels is clean and smooth. Overtime, for many reasons, the inner surface of the heart blood vessels (coronary arteries) may start becoming bumpy/lumpy or blocked due to fat (cholesterol) deposits called "atherosclerotic plaque". This in turn reduces the amount of blood flow available causing "ischemia" (oxygen deprivation). ...Read more

Overlap: Cardiac ischemia can be the result of coronary artery disease, cad, the latter being a progressive disease that can result in plaque/cholesterol building up in the coronary arteries and these stenoses or blockages can impair blood flow to the heart.Ischemia is the condition of blood flow and so oxygen being kept from a part of the body; cardiac ischemia is when this deprivation occurs in heart. ...Read moreSee 2 more doctor answers
