Of infarction specific enzymes, Troponins or other specific biochemical markers.
High-sensitivity Troponin T tests are not readily available, but they will be soon.
If the Troponin is negative,
a treadmill exercise test or a thallium scintigram may be requested.
Both Troponin types are commonly checked because they are
the most specific enzymes to a heart attack.
A blood test is generally performed for cardiac Troponins twelve hours after onset of the pain.
When muscle or heart cells are injured, Troponin leaks out, and its levels in your blood rise.
A blood test that measures a chemical called Troponin is the usual test that confirms a heart attack.
For this reason, doctors often order Troponin tests when patients have chest pain
or otherheart attack signs and symptoms.
For this reason, doctors often order Troponin tests when patients have chest pain

The cardiac enzymes that doctors measure to see if a person
is having a heart attack include Troponin T(TnT) and Troponin I(TnI).
In 11.8% of the deaths reported by the National Health Commission of China,
heart damage was noted by elevated levels of Troponin or cardiac arrest.
Hospitals regularly use Troponin testing to diagnose heart attacks, but a high-sensitivity
test can detect small amounts of damage in individuals without any symptoms of heart disease.
Troponin blood tests:
these are used to determine if there has been recent heart injury- for example, a heart attack which may have caused the respiratory failure.
Prof mills said:"Troponin testing will help doctors to identify
apparently healthy individuals who have silent heart disease so we can target preventive treatments to those who are likely to benefit most.
In their study, Prof Nicholas Mills and
colleagues found men who had higher levels of Troponin in their blood were more likely to have a heart attack
or die of heart disease up to 15 years later.
I wasn't the least bit surprised when the heart tracing came back normal and I was in the middle of getting dressed and heading for the exit when the A&E doc appeared,
waiving my Troponin levels in one hand
and the Guinness Book of Records in the other.
