Prevention & lipidsCohort study
Aspirin use, lipoprotein(a), and calcific aortic valve disease: the Multi-ethnic Study of Atherosclerosis
- Prospective cohort study (secondary analysis of MESA)
- exploratory analysis
- observational
Authors' conclusion
In this exploratory analysis of prospective observational cohort data, regular aspirin use was associated with a lower risk of AVC and severe AS in persons with high Lp(a), but not high LDL-C.
Study context
- Population
- Participants in the Multi-Ethnic Study of Atherosclerosis; mean age 62 years, 53% womenup to 6598
- Participants
- 6,598 participants
- Exposure
- Regular aspirin use vs No regular aspirin use
- Outcome
- Incident aortic valve calcium (AVC, cardiac CT) and severe AS, across Lp(a) and LDL-C levels
Main finding
As reported in the abstract
Incident AVC and severe AS by Lp(a) and LDL-C stratum
HR
- incident aortic valve calcium (AVC), Lp(a) ≥75 mg/dL
- .42 (95% CI .19-.93)
- incident AVC, Lp(a) ≥100 mg/dL
- .17 (95% CI .04-.67)
- severe aortic stenosis (AS), Lp(a) ≥50 mg/dL
- .13 (95% CI .04-.47)
- severe AS, Lp(a) ≥75 mg/dL
- .02 (95% CI .001-.29)
- incident AVC, LDL-C ≥130 mg/dL
- 1.02 (95% CI .66-1.58)
- incident AVC, LDL-C ≥160 mg/dL
- 1.51 (95% CI .53-4.28)
- severe AS, LDL-C ≥100 mg/dL
- .70 (95% CI .39-1.26)
- severe AS, LDL-C ≥130 mg/dL
- .46 (95% CI .14-1.47)
Observational data: associations, not effects.
Further findings
Cohort incidence
- Regular aspirin use
- 23%
- Developed AVC (median 8.9 years)
- 8%
