Insights
Dilated cardiomyopathy (DCM) is a heart muscle disease causing enlarged ventricles and poor pumping. This review covers genetic factors, clinical aspects, and management of familial DCM.
Area of Science:
- Cardiology
- Genetics
- Molecular Biology
Background:
- Dilated cardiomyopathy (DCM) is a myocardial disorder characterized by ventricular enlargement and impaired systolic function.
- DCM leads to heart failure, arrhythmias, thromboembolism, and premature death, incurring substantial healthcare costs.
- While acquired factors are common causes, inherited genetic variants play a significant role in DCM etiology.
Purpose of the Study:
- To review current understanding of familial dilated cardiomyopathy.
- To outline molecular pathogenesis, clinical presentation, natural history, and management strategies for familial DCM.
Main Methods:
- Literature review of familial dilated cardiomyopathy.
- Synthesis of current concepts in molecular pathogenesis.
- Analysis of clinical presentation and natural history.
- Review of management approaches for familial DCM.
Main Results:
- Familial DCM is increasingly recognized as a significant etiological factor.
- Genetic variants contribute to cardiomyocyte dysfunction and survival.
- Understanding of familial DCM pathogenesis, presentation, and natural history is evolving.
Conclusions:
- Familial DCM requires comprehensive understanding for effective management.
- Further research into genetic underpinnings is crucial.
- Integrated approaches to diagnosis and treatment are necessary.
Abstract:
Dilated cardiomyopathy (DCM) is a myocardial disorder defined by ventricular chamber enlargement and systolic dysfunction. DCM can result in progressive heart failure, arrhythmias, thromboembolism, and premature death, and contributes significantly to health care costs. In many cases, DCM results from acquired factors that affect cardiomyocyte function or survival. Inherited genetic variants are also now recognized to have an important role in the etiology of DCM. Despite substantial progress over the past decade, our understanding of familial DCM remains incomplete. Current concepts of the molecular pathogenesis, clinical presentation, natural history, and management of familial DCM are outlined in this review.
