Troponin is actually a normal protein that is synthesized in the body, for low troponin. It is actually mainly seen in some cachectic patients, that is, the nutritional status is very poor, may appear low troponin, but for a group of people who have no symptoms, no disease. So if you have low troponin, don’t worry, you don’t need to do anything about it. First of all, troponin is actually a marker of myocardial necrosis, and if it is high, it is very significant and a direct indication that there is myocardial cell necrosis. Because troponin, regardless of cardiac troponin or troponin, it is mainly present in the cardiac muscle cells, once the myocardial cells necrosis will be released into the blood, the blood troponin will be high. Therefore, its elevation suggests myocardial cell necrosis, such as acute myocardial infarction, acute viral myocarditis, but for low troponin, it is often of no significance. There is no need to worry about entanglement. It is also only occasionally seen in patients with cachexia, where protein synthesis is relatively low.
