Direct VIsualiZAtion of Asymptomatic Atherosclerotic Disease for Optimum Cardiovascular Prevention. A Population Based Pragmatic Randomised Controlled Trial Within Västerbotten Intervention Programme (VIP) and Ordinary Care.
In Brief
A clinical study evaluating Intervention for Cardiovascular Diseases. Active but no longer recruiting, targeting 3,532 participants across 1 site.

Detailed Summary
The purpose of VIPVIZA is to assess the impact of pictorial information about asymptomatic atherosclerotic disease to both physician and patient, for improving physicians' adherence to prevention guidelines and patient perception and understanding of the cardiovascular disease (CVD) risk and consequent motivation for prevention. The intervention effect is assessed by differences between randomization groups in the primaryboutcome Framingham Risk Score (FRS) and the secondary outcomes the Systematic COronary Risk Evaluation (SCORE) as well as changes in these scores after one, three and six years. Secondary outcomes are also atherosclerotic disease progression, as assessed by repeated carotid ultrasound examination after three and six years, as well as the prevalence of acute events and mortality after 10 years . Social, psychological and cognitive determinants of behavioral change as well as the intervention impact on novel biomarkers will also be explored.
Study Details
Timeline
Arms & Interventions
The intervention: Giving communication about risk of cardiovascular disease in the form of written and graphical information about silent atheroscslerosis measured by carotid ultrasound examination as carotid intima-media thickness, highlighted as vascular age, and plaque formation, visualized as a traffic light (green - no plaque, red - plaque).The ultrasound results are given to the study person and his/her physician, in addition to information about conventional risk factors for cardiovascular disease
The comaparator is that the study person and his/her physician do not get any information about carotid ultrasound results on silent atherosclerosis. They are only informed about results of measured conventional CVD risk factors
Interventions
Information about carotid ultrasound results to the participant and his/her primary care physician in the form of atherosclerosis highlighted graphically in color against normal vascular age patterns and as plaque formation. General information about atherosclerosis as a dynamic modifiable process and recommendation to follow clinical guidelines for risk factor control. After 2-4 weeks a follow-up call by a research nurse, to give additional information and reassurance, if needed. Identical information to the study participant is sent by post after 6 months. CVD risk factors are managed according to clinical guidelines within primary health care during the entire study period.
