The value of copeptin in the diagnosis and prognosis of cardiovascular diseases

Vasopressin and its receptors play a key role in maintaining homeostasis in physiological and pathophysiological conditions. As a result, the vasopressin system has become an important target for both diagnostic and therapeutic use in a number of diseases. Kopeptin, C-terminal part of vasopressin prohormone. Copeptin has come to be seen as an important marker for identifying high-risk patients and predicting outcomes for various diseases. This improves the clinical value of commonly used biomarkers and risk stratification tools. The area that could benefit most from the introduction of the copeptin measurement in practice is cardiovascular disease. Determination of the level of copeptin becomes a fast and reliable method of differential diagnosis, especially in acute coronary syndromes. A special role in the diagnosis of acute myocardial infarction (AMI) is given to the combination of copeptin and troponin. According to available sources, such a combination eliminates AMI with very high sensitivity and negative predictive value. Moreover, elevated levels of copeptin correlate with poorer prognosis, and a higher risk of side effects after AMI, especially in patients with heart failure.
