Autophagy in Heart Failure: Insights into Mechanisms and Therapeutic Implications

Area of Science:

• Cardiovascular Biology
• Cellular Biology
• Molecular Medicine

Background:

• Autophagy is a critical cellular process for clearing damaged components and maintaining heart function.
• In heart failure, autophagy acts as a protective mechanism against disease progression.
• Its significance is established in both animal models and human heart studies.

Purpose of the Study:

• To review the role of autophagy in heart failure progression.
• To consolidate current knowledge on autophagy deregulation in heart failure.
• To explore the therapeutic potential of targeting autophagy.

Main Methods:

• Comprehensive review of published data on autophagy in heart failure.
• Analysis of genetic and pharmacological interventions affecting autophagy.
• Examination of autophagy's molecular mechanisms in cardiomyocytes, cardiac fibroblasts, and endothelial cells.

Main Results:

• Autophagy deregulation, through genetic or pharmacological means, impacts ischemic and non-ischemic heart failure models.
• Autophagy influences key cellular processes in cardiomyocytes, cardiac fibroblasts, and endothelial cells.
• Current research highlights the complex involvement of autophagy in heart failure pathophysiology.

Conclusions:

• Autophagy plays a dual role in heart failure, potentially protective or detrimental depending on context.
• Further research is needed to fully elucidate the therapeutic strategies targeting autophagy for heart failure.
• Targeting autophagy holds promise for novel heart failure management approaches.
