B. Molecular Action
Precisely counters hypercontractility caused by sarcomere mutations
III. Novel Target Identification & Validation
Systems biology approaches have uncovered promising therapeutic targets:
- Proteomic Screening:
- Identified 10+ novel targets through myocardial protein interaction mapping

Conclusion: The Precision Cardiology Era
Myocardial hypertrophy therapeutics have evolved through three revolutions:
- Targeted Modulation: From symptom management to disease-specific myosin inhibition
- Multi-Omics Integration: System biology uncovering novel regulatory networks
- Personalized Paradigms: Genetic stratification guiding therapeutic selection
“We stand at an inflection point where molecular therapies transform hypertrophy from irreversible pathology to manageable condition – ultimately preventing progression to heart failure.”
