Troponins peak after seven hours and remain elevated for up to seven days. Troponins are muscle structure (contraction) proteins, which are released into the blood after muscle damage. Troponin I and C are markers of cardiac muscle damage, which is commonly used to differentiate between an angina and a myocardial infarction (MI). MI often results in significant troponin I release compared to angina, although care is needed when making a final interpretation, as some non-myocardial events (like tachycardia) can raise troponins. Patients with chronic obstructive pulmonary disease (COPD) may also have increased levels of troponins, given the ischaemic and hypoxic nature of the disorder.
