Hypertrophic cardiomyopathy (HCM), a genetic heart disorder, is increasingly understood beyond a single gene. Advances in imaging and risk stratification are transforming it into a treatable chronic condition.
Area of Science:
- Cardiovascular Genetics
- Genetic Cardiology
- Inherited Cardiovascular Diseases
Background:
- Hypertrophic cardiomyopathy (HCM) is the most prevalent inherited cardiovascular disease.
- Historically viewed as a single-gene disorder affecting the sarcomere, recent research questions this hypothesis.
- HCM is a significant cause of sudden cardiac death, particularly in younger individuals.
Purpose of the Study:
- To review the evolving understanding of HCM.
- To highlight the role of multimodality imaging in diagnosis and management.
- To discuss the transition of HCM from a cause of sudden death to a manageable chronic illness.
Main Methods:
- Review of recent scientific literature and clinical studies.
- Analysis of advancements in genetic research and phenotyping.
- Evaluation of the impact of multimodality imaging techniques.
Main Results:
- HCM's etiology is more complex than initially thought, challenging the single-gene hypothesis.
- Multimodality imaging improves early diagnosis, phenotyping, and identification of treatable conditions.
- While still a risk for sudden death, HCM management has improved, reducing mortality in younger populations.
Conclusions:
- HCM management has shifted towards treating it as a chronic, manageable condition.
- Improved risk stratification and early intervention are key to better patient outcomes.
- Continued research into HCM genetics and phenotyping is crucial for advancing care.
