By these standards, this is a terminal condition because in severe cases its annual mortality may exceed 60 %1 Even in so called mild cases detected in community screening programmes such as the Framingham study the five year mortality approached 50 %.2 These survival rates are worse than for many of the common forms of cancer, emphasising that heart failure is indeed a malignant condition. Heart failure also imposes a heavy burden of symptoms. In studies of the major chronic illnesses such as diabetes, arthritis, and hypertension, heart failure had the greatest negative impact on quality of life, and not just slightly so.3,4 The high morbidity is also reflected in the number of hospital admissions for heart failure, about 120 000 cases each year in the United Kingdom.5,6 These represent 5% of all adult medical and geriatric admissions and are about the same as the number of admissions for acute myocardial infarction.7 Heart failure is a serious public health problem, with a prevalence in the United Kingdom, Scandinavia, and the …
