Practical tips:

• All first-degree relatives of patients with HCM should be screened for the disease with an ECG and echocardiography.
• Heart failure symptoms in patients with HCM may be due to diastolic dysfunction (most common), outflow tract obstruction (less common), rhythm disturbance, or concomitant valvular or ischemic heart disease (Table 30 - Cardiac hypertrophy including HCM versus RCM).
