In the clinic, there are actually more reasons that can lead to elevated troponin, such as acute infarction, myocarditis, arrhythmia, heart failure and other diseases, as follows: 1, acute infarction, myocarditis: it is more common that patients with myocarditis and acute myocardial infarction, in the acute phase of the disease, may generally be accompanied by elevated troponin, but it does not mean that as long as the troponin is high, the patient must have acute infarction, myocarditis. 2. arrhythmias: there are other problems that may lead to elevated troponin levels, such as tachycardia, atrial fibrillation, or supraventricular tachycardia, which may lead to elevated troponin levels. 3. heart failure: some patients may also have elevated troponin levels when they have acute heart failure. If heart failure is accompanied by elevated troponin, it often means that the patient has a poor prognosis. 4, other diseases: some people have elevated troponin, which may be due to aortic coarctation, pulmonary embolism, renal failure, acute pericarditis, which can also cause secondary elevation of troponin.
