Introduction

Heart disease remains one of the leading causes of mortality worldwide, with conditions such as myocardial infarction, heart failure, and cardiomyopathies posing significant health challenges. Conventional treatments, including medications, lifestyle modifications, and invasive procedures lie stenting or bypass surgery, have improved survival rates but do not offer definitive cures. In recent years, messenger RNA (mRNA) therapies have emerged as a groundbreaking advancement in medicine, particularly in the fields of vaccines and genetic disorders. The same technology that enabled the rapid development of COVID-19 vaccines is now being explored for its potential to regenerate heart tissue, improve vascular function, and even reverse heart damage. This article delves into how mRNA therapies are poised to transform the landscape of cardiology and revolutionize heart disease treatment. [1,2].

Messenger RNA (mRNA) is a single-stranded molecule that carries genetic instructions from DNA to the cellular machinery responsible for protein synthesis. In the context of therapeutic applications, synthetic mRNA can be engineered to instruct cells to produce specific proteins that can aid in disease treatment. Unlike traditional gene therapy, which integrates genetic material into the host genome, mRNA therapies provide transient but highly targeted protein expression without the risk of permanent genetic alterations.The heart has a limited capacity for self-repair, making heart disease particularly challenging to treat. mRNA-based therapies offer several potential advantages. [3,4].

One of the most exciting applications of mRNA therapy is in the regeneration of heart muscle cells (cardiomyocytes) after a heart attack. Researchers have identified key proteins, such as vascular endothelial growth factor (VEGF) and fibroblast growth factor (FGF), that promote blood vessel formation and tissue repair. By delivering mRNA encoding these proteins to the heart, scientists aim to enhance healing and improve cardiac function.Chronic inflammation and excessive scar tissue formation (fibrosis) contribute to heart failure progression. mRNA therapies can be designed to modulate inflammatory responses and reduce fibrosis by instructing cells to produce anti-inflammatory proteins or enzymes that break down excess scar tissue. [5,6].

Many forms of heart disease result from reduced blood supply due to narrowed or blocked arteries. mRNA therapies can stimulate the production of angiogenic factors that promote the formation of new blood vessels, thereby restoring oxygen and nutrient supply to the heart muscle.Some forms of cardiomyopathy and arrhythmias are caused by genetic mutations. mRNA technology could be used to transiently express functional versions of defective proteins, restoring normal heart function without permanently altering the genome. [7,8].

Several preclinical and early clinical studies have demonstrated promising results in the application of mRNA for heart disease. Researchers have successfully used mRNA to induce the proliferation of cardiomyocytes in animal models, leading to improved heart function after injury. Notably, biotech companies and research institutions are developing lipid nanoparticle (LNP) formulations that can efficiently deliver mRNA to heart cells while ensuring stability and targeted uptake.One of the groundbreaking developments in this area is BioNTech’s efforts to expand mRNA-based treatments beyond infectious diseases. Their research, in collaboration with academic institutions, explores the potential of mRNA in heart regeneration. Similarly, Moderna has announced interest in cardiovascular applications of mRNA, leveraging its vaccine technology platform for innovative cardiac treatments. [9,10].

Conclusion

The potential of mRNA therapies for heart disease is undeniably exciting. As research progresses, it is expected that refinements in delivery systems, improved mRNA stability, and targeted approaches will make these therapies a viable option for millions of patients worldwide. Given the rapid advancements in mRNA technology, the coming years may witness clinical breakthroughs that redefine how heart disease is treated.
