Modern Approaches to the Assessment of Laboratory Indicators in Heart Failure

Heart failure (HF) is a growing global medical and social challenge, significantly impacting quality of life, lifespan, and healthcare economics. Modern laboratory diagnostics have become crucial in managing HF patients, primarily due to the discovery of natriuretic peptides (BNP/NT- proBNP), which serve as key markers for diagnosis, severity assessment, and treatment monitoring. Beyond natriuretic peptides, a comprehensive biochemical blood analysis including electrolytes, kidney and liver function indicators, lipid profile, and inflammatory markers helps identify comorbidities and aggravating factors like insulin resistance. These investigations are indispensable for personalized treatment selection, prognosis, and timely therapy adjustments, as HF is currently incurable but its progression can be slowed. Therefore, an integrated approach to laboratory diagnostics is fundamental for effective heart failure management.
