Title: Heart Failure: A Controlled Trial Investigating Outcomes of Exercise Training (HF-ACTION)
Brief Summary: The purpose of this study is to determine the long-term safety and effectiveness of exercise training for individuals with congestive heart failure (CHF).


Options:
A: Inclusion Criteria:

* Heart failure clinical score greater than or equal to 3
* Age 60 and over
* Normal ejection fraction greater than or equal to 50%
* BMI greater than or equal to 30

Exclusion Criteria:

* Valvular heart disease
* Significant change in cardiac medication \<4 weeks
* Uncontrolled hypertension
* Recent or debilitating stroke
* Cancer or other noncardiovascular conditions with life expectancy less than 2 years
* Significant Anemia
* Renal insufficiency (creatinine \>2.5mg/dl)
* Psychiatric disease- uncontrolled major psychoses, depressions, dementia, or personality disorder
* Plans to leave area within 6 months
* Refuses informed consent
* Failure to pass screening test:pulmonary function, echocardiogram,or exercise
B: 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
C: Inclusion Criteria:

* COPD new GOLD classification (B, C and D class) and a spirometry in the previous year and
* Systolic and/or diastolic CHF defined at least by an echocardiogram performed in clinical stability; II, III and IV New York Heart Association class and optimized drug therapy.
* Informed consent signed

Exclusion Criteria:

* Physical activity limitations caused by non-cardiac and/or pulmonary problems
* Obstructive Cardiomyopathies and/or myocarditis
* Non cardiac and/or pulmonary pathologies that would cause the death of the patient during the study
* Poor adherence and compliance of the patient
D: Inclusion Criteria:

* Sedentary (structured exercise \< 2x 30 min/wk)
* At least 40 years old
* Preserved systolic function LVEF \> 50%
* Signs and symptoms of heart failure class NYHA II or III
* Diastolic dysfunction (E/é \> 15 or E/é 8-15 and NT-proBNP \> 220 pg/ml)
* Clinically stable for \>= 6 weeks
* Optimal medical treatment for \>= 6 weeks
* Written informed consent

Exclusion Criteria:

* Non- HFpEF causes for HF symptoms (significant valvular or coronary disease, uncontrolled hypertension or arrhythmias, primary cardiomyopathies)
* Significant pulmonary disease (FEV1 \< 50% predicted, COPD GOLD III-IV)
* Inability to exercise or conditions that may interfere with exercise intervention
* Myocardial infarction in the previous three months
* Signs of ischemia during exercise testing
* Comorbidity that may influence one- year prognosis
* Participation in another clinical trial
