Aficamten and Patient-Reported Outcomes in Real-World nHCM (CAMPHOR-HCM)
Comprehensive Aficamten Management and Patient-reported Health Outcomes in Real-world nHCM
This multicenter, prospective, observational, real-world clinical study aims to evaluate the efficacy and safety of Aficamten in patients with symptomatic non-obstructive hypertrophic cardiomyopathy (nHCM) by prospectively observing changes in symptoms, biomarkers, imaging findings, and adverse reactions, etc. It will also record the dosing regimens at which individual patients achieve steady state, and explore the treatment patterns of Aficamten in Chinese patients with symptomatic nHCM.

Age 18-85 years.
-
Confirmed diagnosis of HCM:
- Left ventricular wall thickness ≥15 mm at any site on echocardiography or cardiac magnetic resonance.
- Left ventricular wall thickness ≥13 mm in individuals testing positive for a pathogenic variant or in genetically affected family members.
