Diagnostic, prognostic and therapeutic aspects of apelin in cardiovascular diseases

Biological markers have been thoroughly incorporated into clinical practice as a convenient and simple method for diagnosing and monitoring the condition of patients. The analysis of biomarkers has found its niche in oncology; however, their application in cardiovascular diseases is still in its infancy. Studies on apelin indicate the potential diagnostic and prognostic significance of the assessment of this marker in patients with cardiovascular diseases. The beneficial effect of apelin on the heart and blood vessels allows us to consider this marker as a therapeutic target. The combination of apelin with other biological markers, particularly brain natriuretic peptide and its precursor, may increase the predictive value of apelin.
