A blood particle’s heart disease link is similar across ancestries
Coronary artery disease odds were about 1.07 times as high per doubling of genetically estimated lipoprotein(a), a fat-carrying blood particle.
Our read
Biomarkers- Studied:
- Cohort study of 657,692 veterans
- What changed:
- Coronary artery disease odds were 1.07 times as high per doubling of lipoprotein(a), with little variation across ancestry groups
- The catch:
- Blood lipoprotein(a) levels were genetically estimated rather than directly measured
- In the record:
- The 285th paper on lipoprotein with results in people; 679 on record in all. Its result on coronary artery disease agrees with 21 of 24 other findings on record; 1 points the other way and 2 found no change.
- Why it’s aging research:
- It bears on staying healthy in midlife and later life.

Among 657,692 VA Million Veterans Program participants, an observational analysis used genetic data to estimate lipoprotein(a), a particle that carries fat in the blood. Health records identified 208,034 participants with coronary artery disease, which affects the arteries supplying the heart. The analysis included 163,922 people with non-European ancestry, including 119,715 with genetic similarity to sub-Saharan African populations.
The researchers accounted for age and sex. Higher estimated lipoprotein(a) levels were associated with higher disease odds. This association varied little across genetic ancestry groups, and no group differed significantly from the overall association. Groups with African ancestry had higher estimated lipoprotein(a) levels than non-African groups. Baseline disease risk varied across ancestry groups.
Why it matters
Coronary artery disease is a concern in aging. The authors said the findings strengthen the biological rationale that lowering lipoprotein(a) may be relevant across diverse populations.
Caveats
The analysis relied on genetically estimated blood levels and existing health records; it did not test whether lowering lipoprotein(a) reduced disease. The findings came from a veterans cohort and were reported in a conference abstract.
