Epidemiology of heart failure.: Ratio of epidemic

The Heart Failure is a complex sindrom with a high prevalence in the population, being about 10% in older than 70 years and it is continuosly increasing. Its incidence in persons older than 65 years is about 1% per year. In developed countries it is the first cause of hospitalitation in older than 65 years, supposing the 5% of total admissions and it is increasing every year. The most of authors recognise that the numbers reach values of epidemic, although it is true that it is difficult to determine and cuantify due to its complexity. Although the supervivence has improved in last years, it continues being in a bad pronostic with a mortality about 50% after 5 years approximately of the diagnostic. In order to its high prevalence and its high rate of admissions-readmissions it supposes a problem of public health due to high assistance work. Globally it is estimated that the direct costs of heart failure suppose 1-2 % of healthy cost of developed countries.
