Any type of reversible or irreversible cardiomyocyte injury can result in elevated serum cTnT and cTnI levels. Researchers and practitioners involved in the diagnosis and treatment of cardiovascular disease, including AMI, should know the key causes and mechanisms of elevated serum cTnT and cTnI levels. This will allow to reduce or completely avoid diagnostic errors and help to choose the most correct tactics for further patient management. The purpose of this article is to discuss the main causes and mechanisms of increase in cardiac troponins concentrations in frequently occurring physiological (physical exertion, psycho-emotional stress) and pathological conditions (inflammatory heart disease, pulmonary embolism, chronic renal failure and sepsis (systemic inflammatory response)) not related to myocardial infarction.Keywords: diagnostics, differential diagnosis, causes of increased concentration, mechanisms of increase, cardiac troponins, troponin T, troponin I, acute myocardial infarction, physical activity, psycho-emotional stress, myocarditis, endocarditis, pericarditis, sepsis, pulmonary embolism, chronic renal failure
