Cardiovascular Biomarkers: Tools for Precision Diagnosis and Prognosis

The present study provides a detailed review of cardiovascular biomarkers critical for the diagnosis, prognosis, and pathophysiology of cardiovascular diseases, the leading cause of global morbidity and mortality. These biomarkers aid in detecting disease onset, progression, and therapeutic responses, providing insights into molecular mechanisms. Enzyme markers like AST, CK-MB, LDH, CA-III, and HBDH are pivotal for detecting myocardial injury during acute events. Protein markers such as CRP, H-FABP, and MPO shed light on inflammation and oxidative stress. Cardiac Troponins, the gold standard for myocardial infarction diagnosis, exhibit high specificity and sensitivity, while IMA and GPBB indicate ischemia and early myocardial damage. Peptide markers, including BNP and NT-proBNP, are crucial for heart failure diagnosis and management, reflecting ventricular stress and remodeling. Novel peptides like MR-proANP and MR-proADM aid in assessing disease severity. Lipid markers such as lipoprotein-associated phospholipase A2 and oxylipins provide insights into lipid metabolism and atherosclerosis. Inflammatory and stress-related biomarkers, including TNFα, IL-6, GDF-15, and Pentraxin 3, illuminate chronic inflammation in CVDs. Hormonal markers like copeptin and endothelin-1 highlight neurohormonal activation, while emerging markers such as ST2, galectin-3, PAPP-A, and TMAO elucidate fibrosis, remodeling, and metabolic dysregulation. The inclusion of microRNAs and long non-coding RNAs represents a breakthrough in biomarker research, offering sensitive tools for early detection, risk stratification, and therapeutic targeting. This review emphasizes the diagnostic and prognostic utility of these biomarkers, advancing cardiovascular care through personalized medicine.
