The Claim

Elevated C-reactive protein (>3.0 mg/L) is associated with a 2.22-fold higher odds of coronary heart disease death over a 15-year period, and this association remains independent of social isolation, indicating that C-reactive protein is an independent predictor of mortality but not a mediator of the relationship between social isolation and coronary heart disease death.

In plain English

People with higher levels of C-reactive protein in their blood have a 2.22 times greater chance of dying from coronary heart disease over 15 years, even after accounting for social isolation. This suggests that C-reactive protein predicts mortality risk on its own, but it does not explain why social isolation is linked to heart disease death.

See the scientific wording

Elevated C-reactive protein (>3.0 mg/L) was associated with a 2.22-fold higher odds of coronary heart disease death over 15 years, but did not explain the increased risk associated with social isolation, indicating that CRP is an independent predictor of mortality but not a mediator of the social isolation–CHD link.

Why this might work

When there is too much inflammation in the body over a long time, it causes fatty buildup in the arteries to grow and become unstable, which can lead to blockages that cause heart attacks and death.

  1. Study: Social isolation, C-reactive protein, and coronary heart disease mortality among community-dwelling adults

    Being lonely increases your risk of heart disease, even if you have high inflammation (CRP). The study shows that CRP alone doesn’t explain why lonely people have more heart disease — loneliness itself is still the bigger problem.
