• Background It is unclear whether lipoprotein(a) is associated with coronary heart disease (CHD) and ischemic stroke events in White and Black adults with atherosclerotic cardiovascular disease (ASCVD). Methods and Results We conducted a case-cohort analysis, including Black and White REGARDS (Reasons for Geographic and Racial Differences in Stroke) study participants ≥45 years of age with prevalent ASCVD (ie, CHD or stroke) at baseline between 2003 and 2007. Baseline lipoprotein(a) molar concentration was measured in participants with ASCVD who experienced a CHD event by December 2017 (n=1166) or an ischemic stroke by September 2019 (n=492) and in a random subcohort of participants with prevalent ASCVD (n=1948). The hazard ratio (HR) for CHD events per 1 SD (1.5 units) higher log-transformed lipoprotein(a) was 1.26 (95% CI, 1.02-1.56) among Black participants and 1.16 (95% CI, 1.02-1.31) among White participants ( value comparing HRs, 0.485). The HR for CHD events per 1 SD higher log-lipoprotein(a) within subgroups with hs-CRP (high-sensitivity C-reactive protein) ≥2 and <2 mg/L was 1.31 (95% CI, 0.99-1.73) and 1.23 (95% CI, 0.85-1.80), respectively ( value comparing HRs, 0.836), among Black participants, and 1.07 (95% CI, 0.91-1.27) and 1.36 (95% CI, 1.10-1.70), respectively ( value comparing HRs, 0.088), among White participants. There was no evidence that the association between lipoprotein(a) and CHD events differed by statin use. There was no evidence of an association between lipoprotein(a) and ischemic stroke events among Black or White participants. Conclusions Higher lipoprotein(a) levels were associated with an increased risk for CHD events in Black and White adults with ASCVD.
