The term heart failure (HF) (or decompensatio cordis) basically describes an acute or chronic situation in which the amount of blood pumped through the circulation by the heart, is insufficient to meet the body’s demands. It is a complex syndrome highlighted by several features including haemodynamics, oxygen consumption and exercise capacity. According to the guidelines of the European Society of Cardiology, HF is defined as a syndrome in which the patient should have the following threefold of features: symptoms of typical of HF; signs typical of HF; and objective evidence of a structural or functional abnormality of the heart at rest (Table 1). | The term heart failure (HF) (or decompensatio cordis) basically describes an acute or chronic situation in which the amount of blood pumped through the circulation by the heart, is insufficient to meet the body’s demands.

The prevalence of HF in the western world is estimated as 1 to 2%, and the incidence is around 5 to 10 per 1000 persons per year REF MOSTERD, HEART 2007. Because at young age coronary heart disease is more prevalent in men, prevalence of HF is also higher in this group compared to age matched women. At older age, prevalence of HF is equal between sexes. | The prevalence of HF in the western world is estimated as 1 to 2%, and the incidence is around 5 to 10 per 1000 persons per year REF MOSTERD, HEART 2007.
