Recent Advances in Aptamers-Based Nanosystems for Diagnosis and Therapy of Cardiovascular Diseases: An Updated Review.

The increasing global prevalence of cardiovascular diseases highlights the urgent need for innovative diagnostic and therapeutic strategies. Aptamers, small single-stranded nucleic acid molecules with exceptional specificity and affinity for target biomolecules, have emerged as promising tools for precise diagnostics and targeted therapies. Their selective binding capabilities provide valuable insights into the molecular mechanisms underlying cardiovascular conditions. When integrated into nanosystems, aptamers enhance the delivery, bioavailability, and stability of diagnostic and therapeutic agents, addressing challenges of solubility and degradation. This integration enables more targeted drug delivery, advanced imaging techniques, and improved therapeutic interventions, ultimately improving the management of cardiovascular diseases. Recent advancements in aptamer selection methodologies, coupled with their unique three-dimensional structures, have significantly expanded their application potential in cardiovascular health. By combining aptamers with nanosystems, novel approaches to cardiovascular disease diagnosis and treatment are emerging, promising enhanced efficacy, safety, and precision. This review explores recent progress in the development and application of aptamer-based nanosystems in cardiovascular diagnostics and therapies.
