Title: The Effect of Rehabilitation for Patients Living With an ICD
Brief Summary: The purpose of this study is to describe the effect and meaning of an outpatient-nursing programme including physical activity for patients with implantable cardioverter defibrillators (ICD).

Hypothesis: The outpatient nursing programme will increase the perceived health and quality of life; improve the management of life from a patient perspective; reduce fear of exercise and increase physical capability and reduce the number of treatment-demanding arrhythmias.


Options:
A: Inclusion Criteria:

* LVEF less than or equal to 35%
* New York Heart Association (NYHA) class II, III, or IV CHF diagnosis in the 3 months prior to study entry, with a minimum of 6 weeks of treatment
* Must be on optimal heart failure therapy according to American Heart Association (AHA), American College of Cardiology (ACC), and Heart Failure Society of America (HFSA) heart failure guidelines, including treatment with angiotensin II converting enzyme inhibitors (ACEI) and beta-blocker therapy, or have documentation justifying why optimal therapy is not being used, including intolerance, contraindication, participant preference, or physician's judgment
* Must be on stable doses of medications (e.g., beta-blocker, ACEI, and additional medications as listed in the study guidelines) for 6 weeks prior to study entry
* Must be in stable medical condition and able to begin an exercise program, as determined by study physician

Exclusion Criteria:

* Comorbid disease, behavioral limitations, or other limitations that would interfere with exercise training, or would prevent completion of 1 year of exercise training
* Pregnant or planning to become pregnant in the year following study entry
* Major heart event or heart procedure within the 6 weeks prior to study entry
* Heart procedure or hospitalization for any reason planned in the future
* Expecting to receive a heart transplant in the 6 months following study entry
* CHF caused by significant uncorrected primary valvular disease (except mitral regurgitation secondary to left ventricular dysfunction); if valve replacement has been performed, may not participate for 12 months following the procedure
* CHF caused by congenital heart disease or obstructive cardiomyopathy
* Performance of exercise training at regular intervals (more than once per week) at a moderate to vigorous intensity at any time in the 6 weeks prior to study entry
* Exercise testing results that would prevent safe exercise training, as defined by the American Association of Cardiovascular and Pulmonary Rehabilitation (AACVPR) guidelines, including abnormal blood pressure response, early ischemic changes, and unexpected life-threatening arrhythmia
* Use of fixed-rate pacemakers, pacemakers with inability to attain target heart rates, or automatic implantable cardioverter defibrillator (AICD) devices with heart rate limits set below the target heart rate for exercise training
* Use of an intracardiac device such as an implantable cardioverter defibrillator (ICD) or a cardiac resynchronization therapy pacemaker in the 6 months prior to study entry (must demonstrate stability for 6 weeks post-procedure)
* Primary physician considers placement of an intracardiac device such as an ICD or a cardiac resynchronization therapy pacemaker probable within 6 months of study entry; will be excluded until such device has been placed and 6 weeks of stabilization have passed
* Participation in another clinical trial that may interfere with study participation, follow-up, or data collection, or that may affect cardiovascular morbidity or mortality
B: Inclusion Criteria:

* Patients from either Toronto General hospital or St. Michael's Hospital who have coronary heart disease,
* Receiving their first ICD implant for secondary prevention of SCD or for primary prevention of SCD and their underlying heart disease was hypertrophic cardiomyopathy.

Exclusion Criteria:

* Not able to read or understand English;
* Evidence of psychosis, dementia or cognitive impairment as documented in the patients' hospital records;
* Receiving an ICD for primary prevention of ICD.
C: Inclusion Criteria:

* In-patients at Copenhagen University Hospital who just received an ICD for the first time.

Exclusion Criteria:

* Patients who:

  * do not understand the instructions,
  * are under 18 years old,
  * are diagnosed with a mental disease,
  * suffer from a competing disease,
  * can not participate in physical training.
D: Inclusion Criteria:

* ICD implanted in the 12 months prior to study entry
* Currently taking beta blocker medication
* Speaks and reads English

Exclusion Criteria:

* Unstable angina, heart attack, or percutaneous coronary intervention (PCI) in the 3 months prior to study entry
* Experienced an ICD shock in the 3 months prior to study entry
* Currently exercises 3 times a week for 20 minutes a day
* Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) score for alcohol consumption greater than 4
* Shore Blessed score for cognitive dysfunction greater than 6

Answer: C
