Plain English summary of protocol
Background and study aims
The significant increase in the average lifespan has resulted in an increase in medical and community resources needed to manage serious age-related diseases, such as cancer and cardiovascular disease (for example, heart disease and stroke). Routine medical checks by general practitioners are often not sufficient to identify a person developing cardiovascular disease. In this study, we aim to
investigate whether advanced cardiovascular screenings will prevent cardiovascular events (such as a heart attack) , and whether the possible health benefits are cost effective.
Who can participate?
Danish men aged between 65-74 years living in the Island of Fyn, and the communities of Vejle and Silkeborg in Denmark
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 are invited to attend an advanced cardiovascular screening examination. The screening includes detecting coronary artery disease and aneurysms (via the use of CT scans), blood pressure tests, tests to check heart rhythm and tests to check for high cholesterol levels and diabetes. Biological samples will be performed for biomarker and translational research. Participants in group 2 (control) receive their usual medical care and are not offered an advanced cardiovascular screening examination.
What are the possible benefits and risks of participating?
For participants in group 1 found to be developing cardiovascular disease, preventive actions, including medical treatment and possibly surgery, will be taken.
Where is the study run from?
Four hospital sites in the Island of Fyn, Vejle and Silkeborg (Denmark)
When is the study starting and how long is it expected to run for?
January 2014 to January 2026
Who is funding the study?
Region of Southern Denmark Research Group

Study information
| Primary study design | Interventional |
|---|---|
| Study design | Randomized, clinical controlled, interventional multicentre trial |
| Secondary study design | Randomised controlled trial |
| Scientific title | The Danish Cardiovascular Screening Trial (DANCAVAS): a large population-based randomized clinical multicenter trial testing combo cardiovascular screening in men aged 65-74 years |
| Study acronym | DANCAVAS |
| Study objectives | The primary hypothesis is that the offer of an extensive circulatory screening and intervention programme fulfills the WHO criteria for screening especially concerning the significance of the diseases, the treatment benefits, and the cost effectiveness. |
| Ethics approval(s) | Southern Denmark Region Committee on Biomedical Research Ethics (S-20140028) and the Data Protection Agency |
| Health condition(s) or problem(s) studied | Cardiovascular disease |
| Intervention | Half of the study participants are randomised to the usual care without any screening (control group), while the other half of participants are invited to a screening and intervention programme that measures traditional risk factors, CAC, aneurysms, and PAD (screening group) and offer general cardiovascular prevention in case of positive finding. |
| Intervention type | Mixed |
| Primary outcome measure(s) |
All cause mortality |
| Key secondary outcome measure(s) |
1. Costs and cost effectiveness after 3, 5 and 10 years to assess possible health and/or societal benefits of the screening. |
