Two blood fat carriers share protein links to heart disease
Protein patterns accounted for an estimated 62% of coronary disease risk linked to triglyceride-rich particles and 14% of risk linked to lipoprotein(a).
Limit: The analyses did not measure whether targeting these proteins prevents coronary disease

An observational study with genetic analyses examined 35,269 UK Biobank participants and 2,918 blood proteins. Researchers compared three types of fat-carrying particles: low-density lipoprotein, triglyceride-rich particles and lipoprotein(a).
Triglyceride-rich particles and lipoprotein(a) shared 36 associated proteins, with both patterns involving inflammation. Scores summarizing these patterns were linked to later coronary artery disease, which affects arteries supplying the heart, even after accounting for particle concentrations. The score for low-density lipoprotein was not clearly linked to disease. There were 1,599 coronary disease events over a median follow-up of 13.7 years. Statistical analysis linked the risk partly to proteins involved in immune activity and changes in blood vessel structure. The researchers replicated the findings in 5,915 participants in the Multi-Ethnic Study of Atherosclerosis.
Why it matters
Coronary artery disease is an age-related disease. The authors proposed inflammatory signaling and changes in blood vessel structure as potential targets for monitoring and treatment.
Caveats
These observational and genetic analyses did not test whether targeting the proteins prevents disease. The congress abstract did not report participants’ ages or sex breakdown.
