  • Functional capacity improvement as determined by the degree of percent change in VO2 MAX following structured exercise rehabilitation [ Time Frame: 6 months ]
    End point to be assessed by cardiopulmonary testing are pre- and post exercise training improvement as expressed by the changes in : VO2 MAX, exercise duration, duration to ventilatory threshold(VT).
  • Safety of exercise training in patients with symptomatic hypertrophic cardiomyopathy [ Time Frame: 12 months ]
    Safety endpoonts: 1) Clinicaly significant arrhythmia during exercise training 2)MACE during follow-up period (ACS, Stroke or Death) 3)Exercise Related Injury 4) Episodes of syncope
  • The change in functional capacity following exercise rehabilitation [ Time Frame: 6 months ]
    End point to be assessed by cardiopulmonary testing pre- and post exercise training. VO2 MAX, exercise duration, duration to VT - are to be determined and compared to baseline values.

Exercise Training in Patients With Hypertrophic Cardiomyopathy
Not Provided
Exercise training (ET) is highly beneficial in heart failure patients and has been suggested to confer significant symptomatic and functional improvements in patients with diastolic dysfunction. Accordingly, the aim of this study was to examine the safety, feasibility of a structured ET program in symptomatic HCM patients.

Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
Hypertrophic Cardiomyopathy
Behavioral: Exercise Training
Exercise will be performed under continuous telemetry monitoring and medical supervision. Each session will include 5-10 worm-up, 30 min of aerobic activity on treadmill or bicycle ergometer followed by 10-15 min of stretch and relaxation exercise. Blood pressure will be obtained before the onset and at the end of each session. Participants will be requested to rest and observed 15-30 min before going home. The exercise intensity will be monitored and adjusted, per protocol, according to RPE using the Borg scale.
  • Experimental: Exercise Training

    Exercise will be performed under continuous telemetry monitoring and medical supervision. Each session will include 5-10 worm-up, 30 min of aerobic activity on treadmill or bicycle ergometer followed by 10-15 min of stretch and relaxation exercise. Blood pressure will be obtained before the onset and at the end of each session. Participants will be requested to rest and observed 15-30 min before going home. The exercise intensity will be monitored and adjusted, per protocol, according to RPE using the Borg scale.

    Exercise prescription will be based upon cardiopulmonary test done at baseline.

    Intervention: Behavioral: Exercise Training
  • Active Comparator: Best Medical Care
    Advanced HCM patients who are eligible to participate in the study but cannot do so for technical reasons will be invited to participate in the project as a control group.These subjects will continue their regular follow up in the Cardiomyopathy Clinic and their usual voluntary physical activity at home.
    Intervention: Behavioral: Exercise Training
