Paper

Among 28,949 UK Biobank participants free of cardiovascular disease, researchers examined 2,774 blood proteins in an observational study with a Mendelian randomization analysis, a method that uses genetic differences. They studied lipoprotein(a), a fat-carrying particle in blood.

Measured lipoprotein(a) levels were associated with 220 proteins. Of these, 110 were linked to later atherosclerotic cardiovascular disease, involving plaque buildup in arteries, or aortic valve stenosis, narrowing of the heart’s aortic valve. The genetic analysis linked genetically predicted lipoprotein(a) levels to 60 proteins. These included groups involved in inflammation, calcium buildup and changes to tissue structure. The authors proposed several proteins as candidate treatment targets.

Why it matters

For age-related artery and valve disease, mapping proteins linked to inherited risk may help guide the search for treatments.

Caveats

The genetic analysis did not test whether targeting these proteins with drugs would prevent artery disease or valve narrowing. The findings came from participants without cardiovascular disease and were reported in a conference abstract.
