The Potential of RNA Therapeutics in Treating Cardiovascular Disease.

Despite significant advances in cardiology over the past few decades, cardiovascular diseases (CVDs) remain the leading cause of global mortality and morbidity. This underscores the need for novel therapeutic interventions that go beyond symptom management to address the underlying causal mechanisms of CVDs. RNA-based therapeutics represent a new class of drugs capable of regulating specific genetic and molecular pathways, positioning them as strong candidates for targeting the root causes of a wide range of diseases. Moreover, owing to the vast diversity in RNA form and function, these molecules can be utilized to induce changes at different levels of gene expression regulation, making them suitable for a broad array of medical applications, even within a single disease context. Several RNA-based therapies are currently being investigated for their potential to address various CVD pathologies. These include treatments aimed at promoting cardiac revascularization and regeneration, preventing cardiomyocyte apoptosis, reducing harmful circulating cholesterols and fats, lowering blood pressure, reversing cardiac fibrosis and remodeling, and correcting the genetic basis of inherited CVDs. In this review, we discuss the current landscape of RNA therapeutics for CVDs, with an emphasis on their classifications, modes of action, advancements in delivery strategies and considerations for their implementation, as well as CVD targets with proven therapeutic potential.
