Effects of statins on myocarditis: A review of underlying molecular mechanisms

Area of Science:

• Cardiology and Pharmacology
• Inflammatory Diseases
• Infectious Diseases

Background:

• Myocarditis is a significant cause of cardiac dysfunction and mortality, particularly in younger individuals.
• It can lead to dilated cardiomyopathy, cardiac arrest, and has been linked to SARS-CoV-2 infection.
• Statins (HMG-CoA reductase inhibitors) are widely used for cardiovascular disease (CVD) prevention and have known pleiotropic effects beyond lipid lowering.

Purpose of the Study:

• To review the mechanisms by which statins may attenuate myocarditis.
• To explore the effects of statins on myocarditis, particularly in the context of SARS-CoV-2 infection and broader CVD.
• To highlight the potential of statins as an adjuvant therapy for myocarditis.

Main Methods:

• Literature review of studies investigating statin mechanisms and effects on myocarditis.
• Analysis of research on statins' pleiotropic actions including lipid oxidation, inflammation, immunomodulation, and endothelial function.
• Synthesis of evidence regarding statin use in myocarditis, COVID-19-associated myocarditis, and general cardiovascular disease.

Main Results:

• Statins exhibit pleiotropic effects that can modulate key pathophysiological pathways in myocarditis.
• Evidence suggests statins may reduce inflammation, improve lipid oxidation, and enhance endothelial function relevant to cardiac injury.
• Statins are being considered as adjuvant therapy for myocarditis, including cases related to SARS-CoV-2.

Conclusions:

• Statins possess multifaceted properties that can counteract inflammatory processes in myocarditis.
• Their anti-inflammatory and immunomodulatory effects make them a promising therapeutic option for myocarditis.
• Further research is warranted to establish optimal use of statins in managing myocarditis and related cardiovascular complications.
