Abstract

Background: Myeloid cells play a central role in atherosclerosis. We investigated the associations between the plasma levels of growth factors and chemokines that regulate myeloid cell homeostasis and function and the risk of first‐time acute coronary events in middle‐aged persons. Methods and Results: We measured baseline plasma levels of macrophage colony‐stimulating factor; monocyte chemotactic protein 1; C‐C motif chemokine ligands 3, 4, and 20; C‐X‐C motif chemokine ligands 1, 6, and 16; and C‐X3‐C motif chemokine ligand 1 in 292 participants who had a coronary event during follow‐up and 366 controls matched for age, sex, and time of inclusion who remained event free. Study participants were recruited from the Malmö Diet and Cancer Study population cohort and had no previous history of coronary artery disease. We found a strong independent negative association between macrophage colony‐stimulating factor and incident coronary events in a forward stepwise Cox proportional hazards model including all biomarkers alongside the classic Framingham risk factors (age, sex, smoking, total cholesterol, high‐density lipoprotein cholesterol, systolic blood pressure), diabetes mellitus, and medication. Conversely, monocyte chemotactic protein 1 had the strongest independent positive association with the outcome. The addition of macrophage colony‐stimulating factor and monocyte chemotactic protein 1 significantly improved the predictive ability of a model including traditional risk factors alone (C statistic 0.81 [95% CI 0.78–0.84] versus 0.67 [95% CI 0.63–0.71]; net reclassification index 0.52 [0.42–0.62]; P <0.001). The combined model led to a 54% net downclassification of participants who did not have a coronary event during follow‐up and was particularly effective in the intermediate‐risk group. Conclusions: High levels of macrophage colony‐stimulating factor and low levels of monocyte chemotactic protein 1 in plasma characterize middle‐aged persons at low risk to develop clinically manifested coronary artery disease.

  • Modified lipids activate intimal inflammatory cells to secrete pro-inflammatory chemokines and cytokines, promoting further recruitment of myeloid inflammatory cells, particularly inflammatory monocytes, in mice and humans.

    “The modified lipids then activate the inflammatory cells present in the intima, which respond by secreting pro-inflammatory chemokines and cytokines that in turn activate circulating leukocytes and the local endothelial cells, thereby promoting further recruitment of inflammatory cells of myeloid origin, particularly a specific subset of circulating monocytes with inflammatory potential, as shown”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
