Title: Exercise Conditioning in Elderly Patients With Heart Failure
Brief Summary: The purpose of this study is :

* To determine if aerobic exercise conditioning can improve symptoms, cardiovascular function and quality of life in elderly patients with congestive heart failure.
* To describe the baseline clinical characteristics, cardiovascular function and neurohumoral function in elderly patients with congestive heart failure.
* To determine the specific cardiovascular and noncardiovascular mechanisms by which symptoms and quality of life may improve following exercise conditioning in elderly patients with congestive heart failure.

* No clinical avoidance reasons.
* Patient with health care registration.
* Agreement from the general practictioner and from the cardiologist that follows the patient.

Exclusion Criteria:

* Age below 18 years old,
