Glycogen storage diseases (GSDs) can impact heart function due to enzyme deficiencies. Early detection and management are crucial for preventing severe cardiovascular outcomes in affected individuals.
Area of Science:
- Biochemistry
- Genetics
- Cardiology
Background:
- Glycogen storage diseases (GSDs) result from inherited enzyme deficiencies affecting glycogen metabolism.
- While liver and muscle are primary targets, cardiac involvement is a significant concern in several GSD types.
- Cardiovascular complications can manifest early in life, posing severe risks.
Purpose of the Study:
- To review the mechanisms and evidence of cardiac involvement in various GSDs.
- To highlight the importance of early diagnosis and cardiovascular risk prevention.
- To discuss current and potential therapeutic interventions for preserving heart function.
Main Methods:
- Literature review of pathophysiological mechanisms.
- Analysis of preclinical, clinical, and epidemiological data on cardiovascular manifestations.
- Synthesis of information on management strategies and molecular therapies.
Main Results:
- GSDs are linked to diverse cardiac disorders through impaired glycogen synthesis or breakdown.
- Cardiovascular consequences can be severe, even in infancy.
- Evidence supports the role of lifestyle and targeted therapies in managing cardiac impact.
Conclusions:
- Cardiovascular complications are a critical aspect of GSDs requiring vigilant monitoring.
- Integrated management strategies, including nutritional and exercise changes, are vital.
- Further research into molecular therapies holds promise for addressing underlying metabolic defects and improving cardiac outcomes.
