Identifying Risk-De-Escalating Markers in PREVENT-Defined Intermediate-Risk Older Adults: Insights From ASPREE
- post hoc analysis
Authors' conclusion
Adding polygenic risk for coronary artery disease to the PREVENT equations may further personalize risk estimates and support clinical decision-making for older adults at intermediate risk for ASCVD events.
Study context
- Population
- Intermediate-risk older adults aged ≥70 years (10-year PREVENT-estimated atherosclerotic cardiovascular disease (ASCVD) risk, 7.5% to 20%) from ASPREE, a randomized trial of low-dose aspirin versus placebo in healthy older adults free of prior cardiovascular events at enrollmentparticipants included, 725 (9.3%) experienced ASCVD events
- Participants
- 7,764 adults
- Comparison
- Each marker relative to a baseline model incorporating variables included in the PREVENT equation
Primary result
As reported in the abstract
ASCVD events · median follow-up of 10.3 years
participants experiencing ASCVD events
725 participants (9.3%)
