What is inferior ischemia, what are the symptoms and can it be cured?


I really need to know what are the symptoms of inferior ischemia and what can cause this kind of heart disease. Is it serious and can it be cured? Is this something that comes before heart attack? Please can someone answer.
----------

inferior ischemia means loss of blood supply to the inferior wall of the left ventricle. the leads on the ekg which would have detected this would be leads 2, 3 and AVF and the t wave will be inverted in these leads. so which arteries supply the inferior wall of the left ventricle ? they are the right coronary artery and the left circumflex coronary artery. so either one of these 2 or both of them is blocked. and yes it can be cured but you need to hurry up and go to the cardiologist before it becomes an infarction  (+ info)

Is ischemia reversible and what is the best medical treatment?


My mother has ischemia and I want to know what the best medical treatment for this and is it reversible?
----------

mother rose - "Ischemia" means there is an insufficient or deficient supply of blood to a body part (as the heart or brain) that is due to obstruction of the inflow of arterial blood (as by the narrowing of arteries by spasm or disease). Depending upon the exact cause and location of the narrowed blood channel, treatment can vary. In the head, a blockage of a carotid artery can be cleaned internally by a surgical procedure called a carotid endarterectomy. In the heart's coronary artery a similar procedure or a coronary artery bypass can be highly successful. A similar situation exists in the legs where a bypass artery graft may be considered. Discuss this with your mom's doctor, if possible.  (+ info)

How are cardiac ischemia and shortness of breath related?


I have had significant shortness of breath and am being treated with inhalers, nebulizer and meds. EKG and chemical stress test results said "provocable ischemia of interior (anterior?) wall ". Haven't gotten results of echocardiogram yet. I had it done 3 weeks ago, shouldn't I have heard something from my PCP by now whether it be good or bad? I am scheduled to see a cardiologist next week. Am I to assume that cardiologist will read echo before I am to see him and that is the way I will get the results?
----------

They can be, shortness of breath can be one of the side effects of decreased heart function.  (+ info)

What kind of treatment available for cerebral ischemia, and what is the success rate of the treatment?


Recently I visited eye doctor as my son is having a squinted eye. After so many tests doctor found out that the back portion of the eye is swollen and he has to undergo MRI. After I search on the internet I found that the swelling could be caused by cerebral ischemia. I am very much worried now as my son is 3 yrs old only now. I would like to know if any treatment available for this, if available what it is and how successful it is. Many thanks for your replies.
----------

As far as supplements go-Niacin(flushing kind), vinpocetine, Ginko Biloba, and CoQ10 .Follow the instructions on the package and make sure you use the standardized versions-consult your pharmacist, especially with any other health problems and other medications either over the counter, or prescriptions.  (+ info)

What is the main cuase of ischemia and how is it linked to myocardial infarction, along with thrombosis.?


Also with atheroma.

Im cofnused with the following terms and how they relate to cuasing myocardial infarction:
1)ischemia
2)thrombosis
3)atheroma
----------

The buildup of atheroma or fatty plaque in the wall of the coronary artery narrows the lumen of the artery resulting in ischemia or inadequate blood flow to the heart. The atheroma may ulcerate releasing materials that cause blood to clot on the surface of the plaque. As the clot enlarges it totally obstructs the artery causing a myocardial infarction or death of cardiac tissue downstream to the obstruction.  (+ info)

Could u please explain what does it mean Mildly positive to ISCHEMIA?


After a tread mill test I got the result and mentioned on the result as I mentioned above,ie: mildly positive to Ischemia? with the question mark.
----------

Ischemia is the medical term for that means that the organ is not getting the blood supply it needs. This is what doctors are looking for when they perform stress test. Your results suggest that your heart gets enough blood at rest, but when you exercise there is an area of your heart that is not getting enough blood flow (ischemia.) This is usually due to a blockage in one of the arteries that supply your heart. There are many treatment options for this, including medical therapy (Aspirin, Beta blockers, etc.), angioplasty with/without stent placement or surgery (coronary artery bypass grafting.) The appropriate treatment is determined by the location, size of area involved, symptoms, etc. Discuss it with your doctor.  (+ info)

What is the difference between Cardiac Ischemia and Coronary Heart disease?


I'm a little confused.
But, isn't ischemian caused by atherosclerosis? When the arteries are narrow they may cause reduced O2 in heart tissue??
----------

cardiac ischemia is reduced oxygen to the heart muscle, after 20 minutes ischemia can lead to infarct or death of the muscle. CAD or coronary artery disease is atherosclerosis of the coronary arteries or progressive narrowing caused by plaques in the vessel wall. Hope that helps  (+ info)

Why are diabetics more prone to silent ischemia?


Please give me an in-depth pathological process so I can understand fully. Thanks!

There is more information here than i can digest and feed back to you.  (+ info)

With a thrombosis does ischemia occur both upstream and downstream of the clot?


I understand that a clot will block blood flow thereby preventing tissue downstream from receiving oxygen however wouldn't the red blood cells, which are trapped upstream of the clot, eventually run out of oxygen and cause upstream tissue to become ischemic too?
----------

It would depend on the degree of occlusion , and it's location. A proximal occlusion would cause more symptoms and cellular necrosis than a distal occlusion. Hopefully if the patient gets to an ER they could administer TPA or Streptokinase, or angioplasty. The saying of the CCU is 'time is muscle".Ischemia and necrosis both occur because of the obstruction of blood flow, how fast you respond to the situation would determine the outcome.  (+ info)

Eye doctors: What is a posterior subcapsular cataract and ischemia of the optic nerve?


My dad went to the eye doctor because he was having trouble with peripheral vision. He is being sent to a specialist and we recieved a copy of the letter saying that is what he has. I have no clue what that means and I need someone to break it down for me so I know what is going on with his eyes. Any info will be appreciated.
----------

cataract is simply the opacity in the lens , some times accumulation of proteins or enlarment of the epithelial cells inside the lens . the lens consists of central portioncalled lens capsule which grows with age in size , the nucleus is surrounded by the cortex and the cortex is surrounded by the capsule , anteriorly the caapsule is called aterior capsule and posteriorly towards the vitrous its called psoterior capsule ,
in posterior subcapsular cataract mostly occur with advancing age the nucleus increases in size and hence cause opacity in the lens , when the opacity is in the cortex near the posterior capsule this condidtion is called posterior subcapsular cataract ..
the ischemia simply means when you have low oxygen to any thing it is injured , ischemia of the optic nerve means the infarction of the part of optic nerve due to insufficient or blocked blood supply to it by the short posterior ciliary arteries ..
hope it helped you in some way !  (+ info)
