- Viewing images of their atherosclerotic plaques make patients more likely to stick to lifestyle modifications and medication.
- The tactic is especially effective if findings are contextualized as vascular age.
Why this matters
- A previous study found that patients do not grasp their cardiovascular risk well when pictograms are used as communication tools.
- This study used the real images of the individual patient to communicate risk and “vascular age.”
- Framingham risk scores (FRS) and European systematic coronary risk evaluation scores (SCORE) differed significantly between intervention and controls:
- Difference in FRS: 1.07 (95% CI, 0.11-2.03; P=.0017).
- Difference in SCORE: 0.16 (95% CI, 0.02-0.30; P=.0010).
- Decrease in FRS from baseline to 1 year was steeper for intervention group: −0.58 (95% CI, −0.86 to −0.30) vs 0.35 (0.08-0.63) for controls.
- SCORE increased in both groups, but significantly less in intervention: 0.13 (95% CI, 0.09-0.18) vs 0.27 (0.23-0.30).
- Pragmatic, open-label randomized controlled VIPVIZA trial, n=3532 (1783 controls; 1749 intervention), age 40, 50, or 60 years with 1+ risk factors.
- Imaging of asymptomatic atherosclerotic disease used in intervention.
- Funding: Västerbotten County Council, others.
- Some differences at baseline between dropouts/remainers in intervention group.
