Authors' conclusion

Polygenic risk is strongly associated with future long-term plaque progression and HRP in patients suspected of having CAD.

Study context

Population
Patients suspected of having coronary artery disease (CAD) with CAD polygenic risk score (PRS) measurement and serial coronary CTA
Participants
288 patients
Exposure
High vs low CAD polygenic risk score
Outcome
Change in percent atheroma volume (PAV), percent noncalcified plaque progression and high-risk plaque (HRP) prevalence
Follow-up
Median scan interval 10.2 years

Main finding

As reported in the abstract

PAV progression · per 10 years of follow-up

1 SD increase in CAD PRS associated with increase in percent atheroma volume (PAV) progression (multivariable adjusted)

0.69%

Observational data: associations, not effects.
