Insights
Obesity may worsen outcomes in hypertrophic cardiomyopathy (HCM), a genetic heart muscle disease. This review explores obesity's impact on HCM phenotypes, symptoms, and management strategies.
Area of Science:
- Cardiology
- Genetics
- Metabolic Diseases
Background:
- Hypertrophic cardiomyopathy (HCM) is a primary inherited heart muscle disease caused by sarcomere protein genetic mutations.
- Clinical heterogeneity in HCM, even within families, suggests environmental factors influence disease presentation.
- Obesity is linked to adverse cardiovascular outcomes and shares pathophysiological traits with HCM.
Approach:
- This review synthesizes current knowledge on the effects of obesity in HCM.
- It examines how obesity impacts cardiac phenotype, clinical symptoms, and treatment approaches.
- The focus is on understanding the interplay between obesity and hypertrophic cardiomyopathy.
Key Points:
- Obesity is prevalent in HCM patients and may exacerbate cardiac dysfunction.
- Shared pathophysiological mechanisms between obesity and HCM warrant further investigation.
- Understanding obesity's role is crucial for personalized HCM management.
Conclusions:
- Obesity significantly influences the cardiac phenotype and clinical course of hypertrophic cardiomyopathy.
- Further research is needed to elucidate the specific mechanisms by which obesity affects HCM.
- Integrating weight management into HCM care may improve patient outcomes.
Abstract:
Hypertrophic cardiomyopathy is one of the most frequently diagnosed primary conditions of the heart muscle. It is considered to be inherited, caused by genetic mutations encoding for sarcomere proteins. The marked heterogeneity in clinical manifestations and natural course of the disease, even among family members sharing the same genetic mutation, has raised the question of non-genetic environmental factors contributing to the phenotype. Obesity has been associated with worse cardiovascular outcomes in the general population. Its prevalence is increased in hypertrophic cardiomyopathy, and the two conditions share some similar pathophysiological and clinical characteristics. In this review, we aim to summarise the effects of obesity in the cardiac phenotype, the symptoms and management in patients with hypertrophic cardiomyopathy.
