[Apoptosis and heart disorders]

Area of Science:

• Cardiology
• Cell Biology
• Pathology

Context:

• Cardiovascular disorders are a leading cause of mortality worldwide.
• Understanding cellular mechanisms in heart disease is critical for developing effective treatments.
• Cardiomyocyte apoptosis, or programmed cell death in heart muscle cells, is increasingly recognized as a significant factor in cardiovascular pathology.

Purpose:

• To review the current literature on the significance of cardiomyocyte apoptosis in the development of cardiovascular disorders.
• To describe the distinctive features of regulation and morphological manifestations of cardiomyocyte apoptosis.
• To present data on the role of apoptosis in specific cardiovascular conditions such as myocardial ischemia, cardiomyopathies, and heart failure.

Summary:

• This review synthesizes research on cardiomyocyte apoptosis, highlighting its regulatory pathways and morphological characteristics.
• Despite the terminally differentiated nature of most cardiomyocytes, apoptosis contributes to cellular loss and dysfunction in various pathological states.
• The review specifically examines the involvement of cardiomyocyte apoptosis in myocardial ischemia, cardiomyopathies, and the progression of heart failure.

Impact:

• Provides a comprehensive overview of cardiomyocyte apoptosis in cardiovascular disease, aiding researchers and clinicians.
• Highlights the importance of targeting apoptosis pathways for potential therapeutic interventions in heart conditions.
• Contributes to a deeper understanding of the cellular basis of heart failure and related pathologies.
