What is the effectiveness of systematic population-level screening programmes for reducing the burden of cardiovascular diseases? Summary

ABSTRACT

Cardiovascular disease (CVD) remains the main cause of death in the WHO European Region. This review of systematic screening programmes for CVD risk factors and preclinical CVD across general populations is a second edition of a report published in 2021. It includes an updated literature search and a more comprehensive investigation of country-level specific screening programmes. This updated review includes final results from two studies which were ongoing in 2021. It also identified 10 new studies, but none of these met the inclusion criteria. It shows that screening for CVD risk factors does not lower CVD morbidity and mortality or health-care expenses. Screening for preclinical CVD slightly reduces mortality and negative outcomes related to abdominal aortic aneurysm; however, the results may be outdated owing to a decline in smoking and improved treatment. Screening for atrial fibrillation or screening for a mixture of risk factors and preclinical CVD has a marginal effect on morbidity and mortality. Serious adverse effects are observed, probably due to overdiagnosis and overtreatment. Most studies were conducted in western European countries. Future research could investigate possible benefits of screening in countries that have not yet been studied. Few countries have national screening programmes for CVD risk factors and preclinical CVD.
