FAQ - myocardial ischemia
(Powered by Yahoo! Answers)

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:

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)

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)

4. What kind of ECG changes would indicate myocardial ischemia?

Thanks for any info you can give.

The 12 lead ECG is used to classify patients into one of three groups:
1. those with ST segment elevation or new bundle branch block (suspicious for acute injury and a possible candidate for acute reperfusion therapy with thrombolytics or primary PCI),
2. those with ST segment depression or T wave inversion (suspicious for ischemia), and
3. those with a so-called non-diagnostic or normal ECG.  (+ info)

EKG T wave changes and Myocardial Ischemia?

My previous ekg results: borderline ekg,anterior T wave changes non especific unconfirmed analysis, and my doctor said everything was fine and didn't send me to a cardiologist. Now, 6 month later i have a new ekg as a preoperative test and result are: borderline abnormal, T wave changes possible due to Myocardial Ischemia. Unconfirmed Analysis. I am very nervous because i was ready to have a plastic surgery in 10 days, and i got this on my ekg. I have levels of anxiety when i got tested. I have no symptoms, just some palpitations when i am close to get my period and doctors told me that could be due to PMS... i would like to know if i have to concern, because i have to wait 3 days to get results from the anestesist. Do i really have to fear a Myocardial Ischemia? I am very confuse, because doctors office assistant told me that readings from the machine is not the answer, but yes the doctor interpretation. I appreciated if somebody have the right answer to me. I excercise 2-3 t a week,

No one on this site can give you the answer.

"The answer" needs to be interpruted as part of a complete history and physical exam. Any test result can only be interpruted in the context of the situation.

A reading of possible myocardial ischemia in a person who isn't actively having symptoms of a heart attack is meaningless. Thats why machines have not replaced doctors. A machine has no common sense.

OK what I can tell you. T wave changes are common. On a screening EKG they sometimes relate to mild enlargement of the heart, they sometimes relate to electrolytes, they sometimes relate to nothing.

A screening EKG is used to tell us if you already had a heart attack. In that case we would see Q waves, a totally different thing than the T wave. Some times people had a silent heart attack and a screening EKG helps us pick this up. A screening EKG has NO PREDICTIVE VALUE,

The question which help predict if you are at risk for heart disease are, ...
Are you as smoker?
Are you a diabetic?
Do you have a family history of heart disease?
Did someone in your family have a heart attack before age 45?
Do you exercise?
Do you have high cholesterol?
Do you get chest pain or pressure with physical exertion?
How many flights of stairs can you walk up before getting out of breath?

You answers to these questions relate to your risk. With increasing amounts of risk we may do tests for heart disease, ...
2-D echocardiogram
stress test
heart catheterization.

Relax, set it aside, forget about it. I'm sorry they even showed you the machine reading. Much ado about nothing.  (+ info)

Myocardial ischemia- how serious and is it treatable?

Hi to all just 1 wk ago my mom was diagnosed with myocardial ischemia through treadmill stress testing. More than a year ago she has been experiencing pain on jaw area going to left arm and sometimes occasional chest pain. She underwent ECG that time, however, it revealed normal finding. We were so determined to know why with the symptoms, so she consulted a cardiologist and told him the signs and symptoms she has been experiencing , but the doctor told her not to worry and instead have an ECG again, which revealed normal finding. The doctor just gave her migraine medications since she also has migraine. But still, although the doctor said nothing about myocardial ischemia or any other heart problem, my mom still experienced the same symptoms. Just a week ago, she underwent treadmill stress test which reveled myocardial ischemia. I'm so dead worried for her, because I kinda know how serious this disease, but still, I want your opinions... I want to know what are the risks of having this disease and is it treatable? She was given aspirin for maintenance and Isordil for chest pain. May I also know, what are the things she should or should not do? Please, I need some more informations.... Thank you and please pray for my mom's health.
she is not hypertensive, in fact, she used to have low BP... ok, i'll tel her to have a follow up check up with her cardiologist, tnx!
by the way, i'm confused what should the doctor monitor? if the meds are taking effect? so you mean it is treatable? and how will they monitor it, by having another treadmill stress test? tnx again!

Everything "Cats" said is correct, especially if she feels chest pain she needs to go to the ER.

She has Coronary Artery Disease (CAD). I am sure your Cardiologist is managing her correctly. Isordil (ISDN) is a good med for CAD. It causes vasodilation which is good. I would ask the Cardiologist if Beta-Blockers would be right for your mom. Sometimes Beta-Blockers are helpful in CAD. You may want to ask your Cardiologist if your mom should take aspirin once a day (often a baby aspirin or two, enteric coated is fine) or Plavix. These two meds stop clots from forming, which is a good thing in CAD. There is a supplement called Co-Q10 that has been shown to have some cardioprotective effects. Even though you can get Co-Q10 over-the-counter, you should ask your Cardiologist about it.

Does your mom smoke? If so, she should stop. If she drinks regularly, she should stop (i'll come back to this). Does she exercise? Even taking a long walk once a day can have PROFOUND impacts on cardiovascular health. What about diet? She should stay away from fatty food, and eat a healthy, well-rounded diet with lots of vegetables.

Okay, going back to drinking. If she is a drinker, she should stop. If she is not a drinker, then she may want to think about adding ONE (and only one) glass of red wine with dinner or before bed. This has been shown to have significant cardioprotective effects. You can also discuss this with the cardiologist.

Good luck, and I wish your mother the best of health.  (+ info)

Myocardial Ischemia and Angina Pectoris are same?

Essentially, yes. Ischemia is when the tissue does not get enough blood and oxygen due to a narrowing or blockage of the coronary arteries. Angina is the pain you feel when you are experiencing ischemia.

Some health care professionals may use the terms interchangeably, leading to some confusion.

Hope this helps!  (+ info)

What is myocardial ischemia ???

My grandma was diagnosed with this. What is it? (Try and keep it simple) -Thanks!!

Myo refers to muscle, cardial to heart and ischemia to
decreased oxyzen situation.

Put it all together --- there is decreased oxyzen supply to muscles of heart . Now we need out heart to keep pumping blood at all times. Severity of the problem depends upon extent and duration of oxygen deprivation. Her doctor can give you details specific to grandma's heart.

Hope it helps. Take care of your grandma.  (+ info)

What is Myocardial Ischemia?

It means that part of the heart is not getting enough blood supply..  (+ info)

I Just Heard "ACS" In a Plavix Ad Again, Does "Idiopathic Transient Myocardial Ischemia", Mean the Same Thing?

Yes and no. ACS is Acute coronary syndrome, which covers stable angina, unstable angina, and myocardial infarction (both STEMI and NSTEMI- terms describing EKG changes). Idiopathic Transient Myocardial Ischemia is a type of angina, one of the diseases covered under the umbrella term ACS.

Plavix is used in the treatment of ACS because it is an anticoagulant since these people are at risk for an myocardial infarction (i.e. heart attack).  (+ info)

Myocardial infarction, angina, ischemia please explain?

can someone please explain these terms, also other common cardiac problems that arise clinically, how they are treated etc.... thankyou thankyou!
