Definition Circulatory failure:an abnormality of some component of the circulation is responsible for the inadequate cardiac output. (heart,the blood volume,the concentration of oxygenated hemoglobin in the arterial blood, or the vascular bed) 3

During the last 10 years the annual number of hospitalizations increased from approximately 550,000 to nearly 900,000 for HF as a primary diagnosis ACC/AHA Guidelines for the Evaluation and Management of Chronic Heart Failure in the Adult(2001) 4

Nearly 300,000 patients die of HF as a primary or contributory cause each year, and the number of deaths has increased steadily despite advances in treatment. Heart failure is primarily a disease of the elderly.Approximately 6%to 10%of people older than 65 years have HF 5
