AIMS The British Heart Foundation's (BHF) annual statistical compendium is a comprehensive source of accessible epidemiological data in relation to cardiovascular disease (CVD) in the UK. Using datasets with multiple years of data from the compendium we have analysed trends in mortality, morbidity, and treatment for CVD within the UK. METHODS AND RESULTS CVD mortality in the UK has consistently declined over recent decades, from 1,045 deaths per 100,000 in 1969, shortly after the BHF was founded, to 255 per 100,000 in 2019. Despite this remarkable improvement, inequalities in CVD mortality persist between the UK nations, for example in 2019 the death rate in Scotland was 326 deaths per 100,000 compared with 246 per 100,000 in England. Improvements in CVD mortality have been paralleled by increased use of primary prevention medications (anti-hypertensives and statins) and interventional procedures. In recent years, progress in mortality outcomes has stalled, probably due to a combination of factors including a rise in risk factors such as obesity and diabetes. In terms of morbidity, CVD remains a significant burden in the UK, accounting for at least 1.18 million hospital admissions and reflect enormous economic burden of CVD, estimated at £19bn in the UK. CONCLUSIONS Our results highlight the importance of accessible and comprehensive statistics in relation to the burden of CVD and the value of the BHF's annual compendium in drawing out conclusions and opportunities for future research. One key area is to improve is the data on which estimation of prevalence is based. There is also a need for ongoing work to better understand the root causes of disparity between socio-economic groups in relation to CVD. One important way to address this will be to improve consistency of reporting of CVD heath data across all nations of the UK. Understanding the causes will inform UK healthcare planning in addition to providing analytical insights that will be applicable in other countries.
