Data from the 2006 Health Survey for England suggest the prevalence of CHD  in England was 6.5% in men and 4.0% in women. Prevalence rates increase with age, with more than 1 in 3 men and around 1 in 4 women aged 75 and over living with CHD.

Overall we estimate that there are just over 1.1 million men living in the UK who have had angina and around 970,000 who have had a heart attack and around 850,000 women who have had angina and around 439,000 who have had a heart attack. Combined these estimates suggest that 2.1 million men and 1.3 million women, around 3.4 million adults, in the UK reporting angina and/or a heart attack. This is likely to be an overestimate as those suffering angina are not an independent group to those suffering from a heart attack.

Data from the General Household Survey allow comparisons to be made between the prevalence of cardiovascular diseases (CVD) and conditions with that of other diseases and conditions. In 2006, CVD was the second most commonly reported longstanding illness in Great Britain (after musculoskeletal conditions).

The Quality and Outcomes Framework (QOF) became part of general practice contracts on 1 April 2004 and provides information on the registrations for a number of different diseases. A very high proportion of practices (>98%) participate in the scheme making the register a good measure of prevalence for particular diseases in the population. Data show that the prevalence of CHD in Britain was 3.7% of all GP registrations. The prevalence of CHD was higher in Scotland (4.6%) than in Wales (4.3%) or England (3.5%). Within countries there is wide variation in the prevalence of CHD. In England the prevalence ranged from 2.3% in London to 4.9% in the North East of England . In Scotland the prevalence was generally higher ranging from 3.9% in Lothian and Orkney to 8.4% in Shetland.

Data from Key Health Statistics from General Practice on the prevalence of treated CHD (heart attack and angina) suggest that the prevalence of all CHD was higher in the North of England and in Wales than it was in the South of England, and was also higher in lower socio-economic groups.

The 2004 Health Survey for England, which focused specifically on the health of minority ethnic groups, suggests that the prevalence of heart attack and angina was higher in Indian and Pakistani men, who were just under twice as likely to have experienced these conditions than men in the general population.  The prevalence of all CHD in Black Caribbean and Chinese men was much lower than in the general population. In women there was less ethnic variation in the prevalence of all CHD, with only Chinese women having levels of all CHD which were lower than those found in women in the general population.
