What Is The Significance Of Myocardial Ischemia
Myocardial ischemia: When the heart muscle can't get enough blood flow to supply its needs we call that ischemia. Narrowed arteries, anemia, overgrown muscle and other things can cause it. Chest pain, weakened heart muscle, rhythm problems and other abnormalities may result. It is treated by a combination of therapies. ...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
Artery blocked: That is just describing the anatomic location of the area of the heart not getting enough blood because of a blockage in a coronary artery. The significance of the blockage itself is that on could cause pain and lead to a heart attack with damage to that part of the muscle. ...Read moreSee 1 more doctor answer
Location: Ischemia is a term meaning that that part of an organ (the heart in this case) is not getting enough blood and oxygen. Anteroapical just refers to the locasion of the blockage. Antero means front of, and apical refers to the apex of the heart, the part that is directed down and to the left, on the opposite side to the aorta. ...Read moreSee 1 more doctor answer
See below: Ischemia implies insufficient blood flow. Myocardial (heart) ischemia is usually due to plaque obstructing blood flow. It can also be due to coronary artery spasm (especially in smokers). Ischemia often causes chest pains but can be painless (silent ischemia). Medical therapy is preferred to control risk factors. Invasive therapy such as angioplasty or bypass surgery is for unstable patients. ...Read moreSee 1 more doctor answer
Blocked Heart Artery: Provocable ischemia occurs when a heart artery is blocked and exercise creates a condition where the heart muscle needs more blood than the artery can deliver. It may create the classic clinical symptom of angina pectoris or chest pain. Tests to diagnose provocable ischemia include the treadmill, nuclear stress/chemical testing, and stress echocardiography. ...Read moreSee 1 more doctor answer
Can be significant: In the heart? In the brain? Microvascular simply refers to the tiny blood vessels, ischemia is a lack of oxygen due to insufficient blood flow. Unlike the larger vessels, where plaque is usually the limiting factor in blood flow, microvascular disfunction is usually due to damage or disease. ...Read moreSee 2 more doctor answers
Location& blood flow: It depends. S the ischemia reverisble or irreversible? Was it detected on a nuclear stress test? Assume it's reversible as seen in a nuclear stress test.Apical refers to the location - at the apex.As for significance, along with other indications, i might suggest a clinical correlation via an angiogram or ccta. The significance could not be determined without a cath or cct. ...Read moreSee 1 more doctor answer
Location: Anterolateral is just the description of the location - in front and to the side - where ischemia is seen in a myocardial perfusion scan. The ischemia - lack of blood flow and therefore oxygen to part of the heart is what is significant! anytime there is insufficient or no blood flow to part of the heart it is critical to restore this flow as soon as possible. ...Read moreSee 1 more doctor answer
Permanent damage: If pictures of the heart during a stress test show a hole in the heart muscle which is there both at rest and during exercise, it indicates that that area has been permanently damaged. No use doing a bypass or angioplasty for that. The damage is done and cannot be reversed. ...Read moreSee 1 more doctor answer
Lack of Oxygen: "ischemia" refers to any condition in which insufficient levels of oxygen are delivered to the tissues. Since oxygen is necessary for cell and tissue function, ischemia can cause symptoms, abnormal organ function and cell/tissue death. In the heart, for example, ischemia can result in chest pain and shortness of breath, loss of muscle strength and pump function and heart attack. ...Read moreSee 2 more doctor answers
Coronary narrowing: Ischemia (which is found on a stress test) connotes heart muscle not getting enough blood flow to meet its needs. Mild ischemia implies that the defect showing up on stress test is more subtle, i.e. That there is slightly less blood flow to the area during stress than at rest. It usually means the severity of underling narrowing is less, though by definition it is still enough to limit flow. ...Read moreSee 1 more doctor answer
