  2. Troponin - Wikipedia

    en.wikipedia.org/wiki/Troponin

    Troponin T (blue) anchors the complex on tropomyosin. Troponin is found in both skeletal muscle and cardiac muscle, but the specific versions of troponin differ between types of muscle. The main difference is that the TnC subunit of troponin in skeletal muscle has four calcium ion-binding sites, whereas in cardiac muscle there are only three.

  3. Cardiac marker - Wikipedia

    en.wikipedia.org/wiki/Cardiac_marker

    Test Sensitivity and specificity Approximate peak Description Troponin test: The most sensitive and specific test for myocardial damage. Because it has increased specificity compared with CK-MB, troponin is composed of 3 proteins- Troponin C, Cardic troponin I, and Cardiac troponin T. Troponin I especially has a high affinity for myocardial injury.

  4. Troponin I - Wikipedia

    en.wikipedia.org/wiki/Troponin_I

    Troponin I is a biomarker that responds to treatment interventions. Reductions in troponin I levels proved to reduce the risk of future CVD. [23] [24] [25] High sensitive troponin I used as a screening tool to assess a person's cardiovascular risk and has the potential to reduce the growing cost burden of the healthcare system. [26]

  5. Troponin T - Wikipedia

    en.wikipedia.org/wiki/Troponin_t

    Troponin T binds to tropomyosin and helps position it on actin, [2] and together with the rest of the troponin complex, modulates contraction of striated muscle. [3] The cardiac subtype of troponin T is especially useful in the laboratory diagnosis of heart attack because it is released into the blood-stream when damage to heart muscle occurs. [4]

    When her tests returned, doctors noticed Hutt experienced heightened levels of troponin, a protein in the heart muscle’s cells, according to the National Library of Medicine. Elevated troponin ...

    On top of that, if the test was done and Lp(a) levels were found to be high—meaning above 50 mg/dL— the doctor would’ve likely said there was nothing that could be done about it.

  8. Cardiac excitation-contraction coupling - Wikipedia

    en.wikipedia.org/wiki/Cardiac_excitation...

    This rate can be altered, however, by nerves that work to either increase heart rate (sympathetic nerves) or decrease it (parasympathetic nerves), as the body's oxygen demands change. Ultimately, muscle contraction revolves around a charged atom (ion) , calcium (Ca 2+ ) , [ 3 ] which is responsible for converting the electrical energy of the ...

  9. Diagnosis of myocardial infarction - Wikipedia

    en.wikipedia.org/wiki/Diagnosis_of_myocardial...

    The diagnosis of myocardial infarction requires two out of three components (history, ECG, and enzymes). When damage to the heart occurs, levels of cardiac markers rise over time, which is why blood tests for them are taken over a 24-hour period. Because these enzyme levels are not elevated immediately following a heart attack, patients ...
