The purpose of this study was to understand the epidemiological status of Fabry in patients with hypertrophic cardiomyopathy or left ventricular hypertrophy through multi-center early identification of high-risk patients in cardiology according to high-risk profiles, supplemented by DBS (dried blood disc) screening tools, and to explore the screening and diagnosis methods of patients with Fabry disease in cardiology, so as to promote the early identification, diagnosis and treatment of Fabry in cardiology.

Inclusion Criteria:

• Meet diagnostic criteria for hypertrophic cardiomyopathy (HCM) in adults (age ≥ 18 years):Imaging of one or more left ventricular segments reveals a maximum end-diastolic ventricular wall thickness of ≥15 mm or end-diastolic ventricular septal thickness or posterior left ventricular wall thickness of ≥13 mm on either cardiac imaging at rest.

Exclusion Criteria:

• 1. Identification of hypertrophic cardiomyopathy caused by mutations in pathogenic genes; 2. Identify the cause of left ventricular hypertrophy (LVH); 3. Aortic valve or mitral valve lesions that can cause hemodynamic changes.
