What is the difference between angina and ischemia?


angina means chest pain -- however not all chest pain correlate to heart problems.
ischemia -- is lost of blood supply to the heart muscle, therefore this causes a pain in that certain are. myocardial ischemia, if untreated will eventually turn into myocardial infarction -- where in the muscle dies because of lack of blood supply and oxygen.  (+ info)

Where is uncontrolled hypertension most likely to cause ischemia and loss of function?


a. kidneys, brain, and retinas
b. peripheral arteries in the legs
c. aorta and coronary arteries
d. liver, spleen, and stomach
----------

a. kidneys, brain, and retinas

Hypertensive encephalopathy (brain dysfunction) and retinopathy (retinal damage) are well known entities. Kidneys are important target organs for hypertensive damage.  (+ info)

Does anyone know about reversible ischemia?


Husband had a stress test today. He has a small area of what they called reversible ischemia. I cannot really find anything that tell me about this condition.
----------

a term cardiologists use to indicate that a persons heart can be saved with an intervention before an event like a heart attack. the intervention is usually a stent or bypass, depending on the severity and vessels involved.  (+ info)

After 5 yrs of diagnosis of arrthymia and ischemia, it seems now I have neither?


Is that possible, or was I being treated for something that I didn't have?
----------

According to the World Health Organization - a very highly respected group - medical care in the US is the absolute worst among all of the industrialized nations on the planet. Thus it is quite possible that you were misdiagnosed and mistreated. It would be helpful to have more information however. If you provide me with specific details I should be able to offer you a much better opinion. It is unfortunate that the US is the only country in the world where medicine is for profit. Physicians profit off the misery of their patients. This to me is unethical. Nonetheless physicians are all to human and greed in matters medical is the rule not the exception. I have personally known more than a few physicians who 'gave' the patient a diagnosis to generate recurrent visits and substantial revenue. In addition in the US we now train technicians rather than clinicians. I am of the old school. If I do not know the diagnosis after a history and physical examination I am not likely to improve the situation by testing. Technicians simply order tests believing that the test will provide the diagnosis. Unfortunately each test has false positives and false negatives. Medical statistics is no longer a routine part of any medical school curriculum in the US. Medical studies in recent years have consistently concluded that only about 20% of physicians are able to properly read and interpret a medical study. This has been shown to lead to unnecessary testing which usually offers equivocal results leading to more testing. To those who understand Bayes Theorem and medical statistics it is clear that each successive test that yields an uncertain result decreases the likelihood that there is a problem. Unfortunately virtually all physicians think quite the opposite. I am sorry if you have had the misfortune of 'poor' medical care. I see patients every day who were misdiagnosed and / or improperly treated. It is tragic and my heart grieves for what was once an honored profession. Medicine is my calling. It is my mission field. Such a statement was once common but it is rare today. You cannot serve two masters - and physicians must choose whether to serve the patient or have the patient serve as a means to income. I hope that you do not have an abnormal heart rhythm or ischemia. I wish you the very best of health. If I may be of further assistance please let me know.  (+ info)

How severe or mild is chest pain caused by anterior ischemia & how do you differentiate it from others?


The severity of pain is different for everyone. What is not painful to me could be excruciating to someone else.  (+ info)

What is provocable ischemia?


I would like more details about this and would like to know just how serious it is. Does this mean a the person with provocable ischemia has heart disease?
----------

You may be referring to provocable cardiac ischemia. Ischemia is an insufficient blood supply. It can be transient (comes and goes) or continuous and chronic. Ischemia can also be spontaneous, meaning it comes out of nowhere. Provocable means that is is aggravated by other factors such as stress, diet or lifestyle. If you or someone you know has provocable ischemia, you or that individual can speak to a doctor about it to get more information that is relevant to the your (or that person's) case. The doctor would have the details.  (+ info)

How does plaque build-up in the heart prodcue a thrombosis, cardiac ischemia, and a heart attack?


The plaque impedes local blood flow in a coronary artery or one of its branches, leading to clot formation. The developing clot further impedes blood flow which reduces oxygen perfusion of heart muscle tissue (ischemia), and when the clot enlarges to completely obstruct the artery lumen, blood supply to the affected area of heart muscle tissue ceases, and the affected muscle tissue dies (myocardial infarction), which constitutes a heart attack.  (+ info)

Not sure If I have Neuropaty or Ischemia, What would be the best specialist?


Dr to see?
----------

A neurologist.  (+ info)

difference between myocardial ischemia and myocardial infarction?


i know that one is necrosis of the heart tissue but how do you distinguish between the two without being able to see that? aren't the symptoms the same?
----------

Ischemia is a decrease in blood flow to the heart muscle, infarction is damage to the heart that involves the death of a certain amount of heart muscle. The doctor can distinguish the difference from the EKG and laboratory tests.  (+ info)

How is ST elevation/depression measured? How much indicates cardiac ischemia?


When doing EKG monitoring, how much ST depression or elevation indicates that the myocardium is ischemic?
----------

ST elevation / depression is measured with respect to the TP segment. 1 mm ST elevation and 0.5 mm ST depression are significant.  (+ info)
