Congestive Heart Failure, Cardiac Failure or Congestive Heart Failure is a clinical condition in which the heart is unable to meet the requirements of the blood supply to various organs in the body.
Incidence of heart failure in the general population is 2%, with 10% of people over age 65 suffer from this syndrome. The rising prevalence in recent years, probably due to the fact that patients survive many more years light treatments such as valve surgery, coronary artery bypass surgery and the like. About half of patients have systolic heart failure (ie suffer from a segment of low emission), unlike what was previously believed that systolic failure is most cases. The other half of patients suffering from heart failure with systolic dysfunction Save (a condition called diastolic heart failure). The main symptoms of heart failure
Non-heart failure issue is major public health problem in industrialized countries. United States nearly a million people are hospitalized each year due to non-heart failure and 50,000 die.
Medical literature there are many categories to distinguish between types of non-heart failure different:With acute Chronic non-sharp burst capacity, with non-flow non-extended single expression. Systolic with diastolic: non-deficiency from lack - the ability of the muscle to contract with such due Mai - ability to relax. Left front Right: one that is induced left ventricular failure - failure - such insufficiency induced left versus right ventricular failure - non-right flow. "Back" and "Forward": that is, the kind that such a rise in volume with an increase in pressure causes.
Each category highlights another important feature of the non-heart failure. Besides, there are criteria for grading the severity of disease. This scale is called NYHA (New York Heart Association), and the steps are:
I - when there is a non-heart failure but asymptomatic patient; II - when there is a slight limitation in the daily activities; III - when there is a significant limitation in the daily activities but the patient comfortable at rest; IV - persistent symptoms.
