Why the study?
Do revised diagnostic criteria incorporating symptoms, ECG, and minor echocardiographic abnormalities improve the identification of hypertrophic cardiomyopathy in adult members of affected families compared to conventional echocardiographic criteria?
Do revised diagnostic criteria incorporating symptoms, ECG, and minor echocardiographic abnormalities improve the identification of hypertrophic cardiomyopathy in adult members of affected families compared to conventional echocardiographic criteria?
Revised diagnostic criteria incorporating symptoms, ECG, and minor echocardiographic abnormalities are proposed to improve the diagnosis of hypertrophic cardiomyopathy in adult relatives of affected patients, as up to 20% of gene carriers lack conventional echocardiographic left ventricular hypertrophy.

Supports expanded HCM screening with ECG/symptoms in families; extends diagnosis beyond echocardiography alone.
McKenna et al. (1997) conducted a review in Hypertrophic cardiomyopathy. Revised diagnostic criteria vs. Conventional echocardiographic criteria was evaluated. Up to 20% of adults carrying a hypertrophic cardiomyopathy gene defect do not fulfill conventional echocardiographic criteria, prompting the proposal of revised diagnostic criteria.
