Precision Medicine in Cardiomyopathy: Advances and Future Directions

Area of Science:

• Cardiovascular Medicine
• Genetics
• Personalized Medicine

Background:

• Cardiomyopathies encompass a range of heart muscle diseases with diverse genetic underpinnings.
• Current diagnostic and treatment strategies often lack personalization, leading to suboptimal outcomes.
• The advent of precision medicine offers a paradigm shift in managing these complex conditions.

Purpose of the Study:

• To review the transformative role of precision medicine in cardiomyopathy diagnosis, classification, and treatment.
• To explore the integration of genetic profiling, biomarkers, and advanced imaging.
• To discuss the application of precision medicine across major cardiomyopathy subtypes and pediatric forms.

Main Methods:

• Comprehensive literature review focusing on precision medicine applications in cardiomyopathies.
• Analysis of genetic drivers, including mitochondrial mutations, across different cardiomyopathy subtypes.
• Evaluation of biomarker and imaging integration for risk stratification and sudden cardiac death prediction.
• Discussion of animal models and emerging therapeutic strategies like gene editing and pharmacogenomics.

Main Results:

• Precision medicine enables tailored diagnosis and treatment by integrating genetic, molecular, and imaging data.
• Genetic profiling identifies key drivers for hypertrophic, dilated, restrictive, and arrhythmogenic right ventricular cardiomyopathies.
• Combined biomarker and echocardiography approaches improve risk stratification, particularly for sudden cardiac death.
• Animal models are crucial for translating genetic findings into clinical understanding.

Conclusions:

• Precision medicine holds significant promise for advancing cardiomyopathy care.
• Targeting underlying genetic causes and tailoring treatments to individual profiles leads to more accurate diagnoses and better outcomes.
• This approach is paving the way for truly individualized cardiovascular care.
