Different studies on the prevalence of heart failure in the community give similar estimates of prevalence.
A recent General Practice Study collected patient data for all men and women aged over 45 years registered at GP practices from 26 general practices across Kent, Surrey and Sussex which shows that prevalence of heart failure increases with age.
The Heart of England study screened patients in the West Midlands using a combination of echocardiography and clinical examination, and European Society of Cardiology criteria for the diagnosis of heart failure were applied. Over 2% of patients (3% of men and 1.7% of women) screened had definite heart failure. Probable heart failure was seen in around a further 1% of patients, which suggests that more than 3% of people aged 45 and over in the UK have definite or probable heart failure.
From these prevalence rates we estimate that there are about 393,000 men aged 45 and over living in the UK with definite heart failure, and 314,000 women, giving a total of around 707,000.
Prevalence of heart failure increases steeply with age, so that while around 1% of men and women aged under 65 have heart failure, this increases to between 6 and 7% of those aged 75 to 84 and between 12 and 22% of those aged 85 and over.
