Key result
An increased circulating level of hs-CRP was a strong independent predictor of ≥2+ extracellular staining of CRP in the infarct-related coronary artery (OR 7.31).
Why the study?
Are levels of inflammatory mediators (sP-selectin, WBC, hs-CRP) higher in the infarct-related coronary artery compared to systemic circulation in patients with acute myocardial infarction?
Cross-Sectional (n=94)
No
Are levels of inflammatory mediators (sP-selectin, WBC, hs-CRP) higher in the infarct-related coronary artery compared to systemic circulation in patients with acute myocardial infarction?
Odds Ratio: 7.31 (95% CI 4.32–33.2)
p-value: p=<0.0001
Inflammatory mediators such as sP-selectin and white blood cells are significantly sequestered in the infarct-related coronary artery during acute myocardial infarction, suggesting a localized role in thrombus formation and stabilization.

Elevated hs-CRP may mark local coronary CRP deposition in AMI; leaves open causal role and therapeutic targeting.
Yip et al. (2006) conducted a cross-sectional in Acute myocardial infarction (n=94). Increased circulating hs-CRP level vs. Lower circulating hs-CRP level was evaluated on ≥2+ extracellular staining of CRP in atherothrombotic tissue (OR 7.31, 95% CI 4.32-33.2, p=<0.0001). An increased circulating level of hs-CRP was a strong independent predictor of ≥2+ extracellular staining of CRP in the infarct-related coronary artery (OR 7.31).
