COGNITIVE IMPAIRMENTS IN CHRONIC HEART DISEASE INSUFFICIENCY

Chronic heart failure (CHF) is a syndrome accompanied by a decrease in cardiac output or an increase in heart filling pressure due to structural or functional disorders of the myocardium. CHF remains an important problem in modern medicine, being one of the main causes of hospitalization and mortality. It affects more than 64 million people worldwide. In Europe, the prevalence of CHF among all functional classes according to the classification of the New York Heart Association (NYHA) is 7%, and for grades III-IV — 2.1%. More than 600,000 patients over the age of 65 are discharged with CHF every year, with a 25% chance of re-hospitalization within 30 days and 70% a year after discharge.
