Multicenter Exploratory Study of Accelerometry in Dilated Cardiomyopathy
Multicenter Exploratory Study of Accelerometry in Dilated Cardiomyopathy
Study evaluates the relationships between daily physical activity levels (PAL) and functional
 capacity (VO2peak) in patients with dilated cardiomyopathy (DCM)
The study will evaluate the daily physical activity with the use of activity monitor, heart
 rate monitor and event monitor in patients with dilated cardiomyopathy (DCM). These wearables
 track the heart rate, heart rhythm, tracks activity and step count. The VO2 peak will be
 measured via the exercise test.
Inclusion Criteria:

 1. Males and females, 18-75 years of age

 2. Diagnosis of dilated cardiomyopathy

 -  (Unexplained left ventricular enlargement (left ventricular end diastolic
 dimension (LVEDD) >95th percentile for gender and height by echo or MRI)

 -  (Left ventricular ejection fraction (LVEF) less than 50%)

 3. CPET within 14 days prior to baseline visit with no intervening change in therapy

 4. Echocardiogram or cardiac MRI within 1 year prior to baseline

 5. Able to walk >100ft without limitation

 6. More than 30 minutes of exercise per week for at least 3 months prior to study
 enrollment, and plan to continue exercising for the next two weeks (duration of
 study).

 7. Ability to provide informed consent and willingness to complete the study (including
 weekly phone follow-up)

 Exclusion Criteria:

 1. Heart failure hospitalization within four weeks prior to enrollment

 2. Non-cardiac limitation of activity

 4. Prior exercise-induced syncope or exercise-induced sudden death 5. Primary exercise mode
 is swimming or stationary biking 6. Participation in competitive or high intensity exercise
 against medical advice 7. Implantable Cardiverter Defibrillator (ICD) placement in the 2
 months prior to enrollment 8. Plan for surgery, device implantation, or significant change
 in clinical management during the two weeks of the study
