Fabry Disease: Cardiac Implications and Molecular Mechanisms

Area of Science:

• Biochemistry
• Cardiology
• Genetics

Background:

• Fabry disease is a genetic disorder caused by deficient alpha-galactosidase A activity, leading to sphingolipid accumulation.
• Cardiac involvement is a major complication, significantly impacting patient prognosis and quality of life.

Purpose of the Study:

• To explore the interplay of metabolic dysfunction, oxidative stress, inflammation, and fibrosis in Fabry disease.
• To understand their contribution to cardiac pathogenesis beyond sphingolipid accumulation.
• To highlight the need for a comprehensive approach to managing Fabry disease.

Main Methods:

• Literature review of biochemical processes and emerging studies.
• Analysis of the relationship between cellular dysfunction and cardiac manifestations.
• Synthesis of current understanding of Fabry disease pathophysiology.

Main Results:

• Mitochondrial dysfunction, oxidative stress, and chronic inflammation are significant contributors to Fabry disease cardiac involvement.
• These factors promote cardiac remodeling, fibrosis, and arrhythmias.
• Current treatments have limitations, indicating a need for novel therapeutic strategies.

Conclusions:

• Beyond sphingolipid accumulation, multiple interconnected pathways drive Fabry disease pathogenesis.
• Targeting metabolic dysfunction, oxidative stress, and inflammation offers potential for innovative therapies.
• A holistic understanding is crucial for effective management of Fabry disease and its cardiac complications.
