Detailed Description:
The CARE-HF study enrolled 813 patients from 82 centers in 12 European countries (Austria, Belgium, Denmark, Finland, France, Germany, Italy, Netherlands, Spain, Sweden, Switzerland, and UK). All patients that were reported to be alive in May 2005 will be asked to participate.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

Chronic heart failure patients with NYHA class III-IV,with a LVEF of less than or equal to 35%, who are on optimal medical treatment, and documented evidence of ventricular dyssynchrony as evidenced by QRS or Echo prior enrollment in the CARE-HF main study.

Patients who have participated in the CARE-HF program and were reported to be alive in May 2005 (study closure of the main study) are asked to participate in the CARE-HF LTFU study.
