Research progress on programmed cell death of cardiomyocytes in pressure-overload hypertrophic cardiomyopathy

Area of Science:

• Cardiovascular Medicine
• Cell Biology
• Pathology

Background:

• Pressure overload hypertrophic cardiomyopathy (PO-HCM) is a common heart condition resulting from chronic pressure overload.
• Excessive pressure leads to cardiomyocyte dysfunction, pathological hypertrophy, and myocardial tissue remodeling.
• The development of PO-HCM involves complex factors including hemodynamic changes, neurohumoral imbalances, and aberrant intracellular signaling.

Purpose of the Study:

• To review and synthesize current research on programmed cell death mechanisms in PO-HCM.
• To highlight the involvement of various cell death pathways in the pathogenesis of PO-HCM.
• To provide insights for translational research and the development of novel therapeutic strategies.

Main Methods:

• Comprehensive literature search of programmed cell death mechanisms in PO-HCM.
• Synthesis of existing data on apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis in the context of PO-HCM.
• Analysis of the role of these cell death pathways in cardiomyocyte dysfunction and cardiac remodeling.

Main Results:

• Programmed cell death plays a critical role in the progression of PO-HCM.
• Multiple cell death modalities, including apoptosis, necroptosis, pyroptosis, autophagy, and ferroptosis, are implicated.
• These pathways contribute to cardiomyocyte loss and the structural remodeling characteristic of PO-HCM.

Conclusions:

• Understanding programmed cell death in PO-HCM is crucial for developing effective treatments.
• Targeting specific cell death pathways may offer novel therapeutic avenues for managing PO-HCM.
• Further research is needed to fully elucidate the interplay of these mechanisms and their therapeutic potential.
