Hypertrophic Cardiomyopathy (HCM)
Subjects with a diagnosis of Hypertrophic Cardiomyopathy
Subjects who are healthy volunteers
- Prevalence of Obstructive Sleep Apnea (OSA). [ Time Frame: Approximately 2 years. ]Measured by the Apnea-hypopnea index (AHI). The AHI is the number of apneas or hypopneas recorded during the study per hour of sleep. It is generally expressed as the number of events per hour. Based on the AHI, sleep apnea is diagnosed if an AHI ≥5 events/hour.
- Determine the severity of Sleep Apnea. [ Time Frame: Approximately 2 years. ]The severity of OSA is classified based on the AHI as follows: None/Minimal: AHI < 5 per hour, Mild: AHI ≥ 5, but < 15 per hour, Moderate: AHI ≥ 15, but < 30 per hour, Severe: AHI ≥ 30 per hour.
- Differences in Autonomic Regulation. [ Time Frame: Approximately 2 years. ]In persons with hypertrophic cardiomyopathy and sleep apnea vs. those without sleep apnea.
- Prevalence of atrial arrhythmias. [ Time Frame: Approximately 2 years. ]Investigators will determine prevalence of atrial arrhythmias, based on prior ECG documented atrial arrhythmias at any timepoint prior to enrolment and up to 4 weeks after the study date. Participants will also have a 48h ECG (extended Holter) recorder attached to screen for atrial arrhythmias.
- Incidence of atrial arrhythmias. [ Time Frame: Approximately 5 years. ]
- Frequency of ventricular arrhythmias. [ Time Frame: Approximately 5 years. ]Investigators will prospectively follow patients with hypertrophic cardiomyopathy to determine the frequency of ventricular arrhythmias in those with vs those without sleep apnea.
- Identify novel biomarkers [ Time Frame: Approximately 5 years ]Participants will be prospectively followed and blood collected to identify biomarkers of arrhythmia, heart failure and prognosis in persons with hypertrophic cardiomyopathy.
- Investigate the association of sleep apnea with atrial and ventricular fibrosis [ Time Frame: Approximately 7 years ]Participants will undergo baseline MRI studies of the heart to determine the burden of fibrosis and its association with sleep apnea. Participants may be invited to complete a follow-up study to track changes in fibrosis.
