Heart failure & cardiomyopathies
Prediction of worsening heart failure in hypertrophic cardiomyopathy using plasma proteomics
Authors' conclusion
The present study with comprehensive plasma proteomics profiling demonstrated a high accuracy to predict worsening HF in patients with HCM and identified the Ras-MAPK and related signalling pathways as potential underlying mechanisms.
