Eur J Prev CardiolPublished

  • Systematic review and meta-analysis
  • random-effects (restricted maximum-likelihood (REML) with Hartung-Knapp-Sidik-Jonkman (HKSJ) adjustment)

Authors' conclusion

Among adults without ASCVD but with elevated Lp(a) or high-risk LPA genotypes, aspirin use did not confer a statistically significant cardiovascular benefit and was associated with numerically higher bleeding risk.
