2 ΚΑΡΔΙΑΚΗ ΑΝΕΠΑΡΚΕΙΑ Καρδιακή ανεπάρκεια ονομάζεται η κατάσταση εκείνη κατά την οποία η καρδιά αδυνατεί να αποστείλει στην περιφέρεια την αναγκαία ποσότητα αίματος για να ανταποκριθεί στις μεταβολικές ανάγκες του οργανισμού ή το κάνει υπό καθεστώς υψηλών πιέσεων.

3 Chronic Congestive Heart Failure DEFINITION The situation when the heart is incapable of maintaining a cardiac output adequate to accommodate metabolic requirements and the venous return." E. Braunwald

5 Staging system of Heart Failure A - patients at risk, but no structural or functional defects, (CAD,HTN, DM, metabolic syndrome, obesity) B - pts with structural heart disease but do not manifest symptoms of heart failure (LV enlargement or dysfunction, LVH, valvular heart disease)

6 Staging system of Heart Failure C - pts with prior or current symptoms that can be controlled with standard medications D - pts with severe disease, frequent hospitalizations, often requiring advanced therapies

7 NYHA Functional Classification Class I - pts with disease but no symptoms that limit activity Class II - pts with slight limitations of physical activity related to symptoms of HF (dyspnea, fatigue) Class III - pts with marked limitations of physical activity, but no symptoms at rest Class IV- pts cannot carry out any physical activity without limitation and may have symptoms even at rest

19 Heart Failure Statistics Prevalence Heart failure (HF) affects an estimated 5.1 million Americans > 20 years of age. By 2013 the prevalence of HF will increase by 25%. 400,000 new cases of heart failure are diagnosed in the United States annually. Incidence One-percent of adults 50 to 60 years of age. Seventy-five percent of HF cases have antecedent hypertension. Ten-percent of adults 80 years of age or older. Mortality and Morbidity The lifetime risk for people with BP > 160/90 mmhg is double that of those persons with BP < 140/90 mmhg At 40 years of age, the lifetime risk of developing HF for both men and women is 1 in 5; at 80 years of age, the lifetime risk of developing new HF is 20%. Most frequent cause of hospitalizations in the elderly and is responsible for 7 to 12 percent of all hospital admissions. Contributes to approximately 275,000 deaths every year.
