Conference paper


It has been estimated that heart failure affects 4.6 million patients in the United States and 22.5 million patients all over the world, and an equal number of patients have asymptomatic left ventricular dysfunction with a high risk of developing heart failure [1]. This condition is the primary discharge diagnosis from hospitals in Western countries. Prognosis is poor, with annual mortality ranging from approximately 10% in NYHA class I-II to 25% in NYHA class III-IV. Heart failure is a condition that principally affects the elderly, and with the progressive ageing of the population it is likely that the prevalence of heart failure will continue to increase during the coming years in both developed and developing countries.
