What is the difference between troponin and troponin I?

Cardiac troponin I appears to be a more specific marker of risk of composite cardiovascular disease and coronary heart disease, whereas cardiac troponin T is more strongly associated with risk of non–cardiovascular disease death.

What is a Type 2 troponin leak?

Type 2 MI is defined as “myocardial infarction secondary to ischaemia due to either increased oxygen demand or decreased supply, e.g. coronary artery spasm, coronary embolism, anaemia, arrhythmias, hypertension or hypotension.”

What is the difference between Type 1 and Type 2 myocardial infarction?

Type 1 MI is a primary coronary arterial event attributable to atherothrombotic plaque rupture or erosion. Type 2 MI occurs secondary to an acute imbalance in myocardial oxygen supply and demand without atherothrombosis.

Which troponin is best?

Overall, troponin I is a better cardiac marker than CK-MB and should become the preferred cardiac enzyme when evaluating patients with suspected myocardial infarction.

Does NSTEMI have elevated troponin?

NSTEMI is diagnosed in patients determined to have symptoms consistent with ACS and troponin elevation but without ECG changes consistent with STEMI. Unstable angina and NSTEMI differ primarily in the presence or absence of detectable troponin leak.

What is cardiac syndrome?

Acute coronary syndrome is a term used to describe a range of conditions associated with sudden, reduced blood flow to the heart. One such condition is a heart attack (myocardial infarction) — when cell death results in damaged or destroyed heart tissue.

Which is worse stemi or Nstemi?

NSTEMI: What You Need to Know. NSTEMI stands for non-ST segment elevation myocardial infarction, which is a type of heart attack. Compared to the more common type of heart attack known as STEMI, an NSTEMI is typically less damaging to your heart.

What does a troponin level of 12 mean?

Cardiac troponin levels are normally so low they cannot be detected with most blood tests. Having normal troponin levels 12 hours after chest pain has started means a heart attack is unlikely. A normal value range may vary slightly among different laboratories.

What’s the difference between ACS and troponin leak?

Thus, many of the non-ACS causes of troponin leak can be classified under a type 2 MI, whereas true ACS would be a type 1 MI. This classification system is now standardized and provides a better classification for MI than the previous traditional classification of STEMI vs NSTEMI.

Can a troponin rise be a sign of acute MI?

Troponin elevation is truly a marker for myocardial injury but not necessarily for diagnosing an episode of ACS or an acute MI. Guidelines on diagnosing an acute MI need to be followed and considered in all cases where there is a troponin rise and clinical evidence suggesting ACS.

Can a type 2 troponin leak lead to misdiagnosis?

The underlying etiology of these type 2 infarctions needs to be treated, as some of these troponin leaks are due to increased demand or changes in cell permeability. Not treating the underlying conditions may lead to misdiagnosis and failure to treat the patient.

Can a syncopal episode cause a troponin leak?

While a syncopal episode can be due to a brain injury or a direct cardiac injury, both however, can lead to troponin leak and need to be differentiated with further diagnostic testing.
