Heart failure (0)

Heart failure is a syndrome manifesting as the inability of the heart to fill with or eject blood due to any structural or functional cardiac conditions.1

Heart failure may be caused by myocardial failure but may also occur in the presence of near-normal cardiac function under conditions of high demand. Heart failure always causes circulatory failure, but the converse is not necessarily the case because various noncardiac conditions (eg, hypovolemic shock, septic shock) can produce circulatory failure in the presence of normal, modestly impaired, or even supranormal cardiac function.

In terms of incidence, prevalence, morbidity, and mortality, the epidemiologic magnitude of heart failure (HF) is staggering. According to the American Heart Association, heart failure is a condition that affects nearly 5.7 million Americans of all ages and is responsible for more hospitalizations than all forms of cancer combined. It is the number 1 cause for hospitalization among Medicare patients. With improvement in survival of acute myocardial infarctions and a population that continues to age, heart failure will continue to increase in prominence as a major health problem in the United States.
