The Emerging Role of Ferroptosis in Cardiovascular Diseases

Area of Science:

• Biomedical Science
• Cellular Biology
• Pathophysiology

Background:

• Ferroptosis is a recently identified programmed cell death characterized by iron-dependent lipid peroxidation.
• It differs morphologically, biochemically, and genetically from apoptosis, necroptosis, and autophagy.
• Cardiovascular diseases are a leading global cause of death, with cardiomyocyte apoptosis traditionally considered the primary cell death mechanism.

Purpose of the Study:

• To review the mechanisms of ferroptosis.
• To elucidate the role of ferroptosis in the occurrence and development of cardiovascular diseases.
• To identify ferroptosis as a potential therapeutic target for cardiovascular diseases.

Main Methods:

• Literature review of ferroptosis mechanisms.
• Analysis of ferroptosis's role in cardiovascular disease pathogenesis.
• Discussion of therapeutic implications.

Main Results:

• Ferroptosis, distinct from apoptosis, significantly contributes to cardiovascular diseases.
• Iron, lipid, and antioxidant metabolism are key players in ferroptosis.
• Emerging evidence highlights ferroptosis's critical role in cardiomyocyte death.

Conclusions:

• Ferroptosis is a major contributor to cardiovascular diseases, challenging the traditional view of apoptosis as the sole mechanism.
• Targeting ferroptosis pathways presents a novel therapeutic strategy for cardiovascular disease prevention and treatment.
