what is the new gold standard diagnosis of MI?

Answer 1

There are multiple criteria used to diagnose an MI. These include the ECG, blood work and the presence of symptoms such as chest discomfort. According to the world health organization a person must have two of the three abnormalities to be diagnosed with a myocardial infarction.

The ECG criteria are 1 mm of ST segment elevation in 2 or more contiguous leads. The laboratory criteria include a typical rise and fall pattern in either the CK and CKMB or troponin levels.

The only true gold standard of an MI would be if typical pathological chnages were seen at autopsy.

Answer 2

There is no real NEW or GOLD standard.
There are blood tests we routinely use in the hospital if a patient is having symptoms of a heart attack. They are the cardiac enzymes & troponin levels. The cardiac enzymes are CPK, CK & CK/MB. These also can indicate mucsular problems because the heart is a muscle. The troponin is usually most indicative. The cardiac enzymes & troponin levels are usually done x3, 8 hrs apart. That can further tell docotrs how bad a heart attack was/is. They usually rise & then gradually fall back down. There are also changes in an EKG during or shortly after a heart attack. Hope that helped

Answer 3

Cardiac catheterization (also called coronary angiography). This is the procedure in which they insert a catheter through an artery (usually the femoral or radial arteries), thread it into the heart, inject radiopaque dye into the coronary arteries, and look for blockages. If there is not a blockage, it is not likey that there has been an MI (though not impossible).
Sometimes there are very obvious signs in other modalities (if you come into the ER with obvious EKG signs, they don't need a cath to make a diagnosis, though you'll almost certainly get one if available for treatment) which make it unnecessary in some cases.

Answer 4

i am not sure about new, but EKG works pretty well. maybe echocardiogram?
