Key result
This review highlights the main reasons and mechanisms for false-positive increases in cardiac troponin levels to aid in the accurate and differential diagnosis of acute myocardial infarction.
Why the study?
False increases in cardiac troponin concentrations lead to incorrect diagnoses and harmful therapies, requiring clinicians to understand the causes and mechanisms of false-positive cTnI and cTnT results.
This review highlights the causes and mechanisms of false-positive increases in cardiac troponins to aid in accurate diagnosis and prevent incorrect therapy.
Supports refined differential diagnosis of AMI; leaves open prospective validation of troponin interpretation algorithms.
Cardiac troponin molecules (cTnI and cTnT) are the most valuable and in-demand biomarkers for detecting various types of myocardial damage (reversible and irreversible, ischemic, inflammatory, toxic, etc.) in current clinical practice. These biomarkers are widely used for early diagnosis of acute myocardial infarction (AMI) and risk stratification of patients suffering from a number of cardiac (such as myocarditis, heart failure, cardiomyopathy, etc.) and extra-cardiac diseases (such as sepsis, renal failure, pulmonary embolism, neurological pathologies, etc.) that negatively affect the cells of cardiac muscle tissue. However, in daily routine clinical activities, internists and cardiologists often encounter cases of false increases in the concentrations of cardiospecific troponins. A false increase in the concentration of troponins contributes to an incorrect diagnosis and incorrect therapy, which can harm the patient. A false increase in the concentration of troponins contributes to an incorrect diagnosis and incorrect therapy, which can harm the patient, therefore, internists and cardiologists should be well aware of the main reasons and mechanisms for false-positive results cTnI and cTnT. This review article mainly focuses on the causes of falsepositive increases in serum levels of cTnI and cTnT, which provide helpful clues for the accurate diagnosis of AMI and evidence for the differential diagnosis.
