Troponin itself has three subunits, TnC, TnI, and TnT, each playing a role in force regulation [citation needed]. Some causes of elevated troponin levels can include: sepsis, which is a severe and potentially life-threatening reaction to an infection entering the bloodstream kidney failure or chronic kidney disease heart failure chemotherapy-related damage to the heart pulmonary embolism heart infection Troponin is a protein that's released into the bloodstream during a heart attack. Detecting troponin in the blood can help doctors diagnose a heart attack 2019-01-25 · Other factors that could contribute to high troponin levels include: intense exercise burns extensive infection, like sepsis medication myocarditis, an inflammation of the heart muscle pericarditis, an inflammation around the sac of the heart endocarditis, an infection of the heart valves Se hela listan på c-Troponin T and c-Troponin I are specific cardiac structural proteins. If there is myocyte injury Troponin will be released. It does not indicate the mechanism of the myocyte injury. High sensitivity Troponin assays allow precise measurement at very low concentrations.
