CRP and atrial fibrillation: However, PTL was associated with a higher median AF MMP-8 concentration and umbilical cord plasma CRP concentration at birth than preterm-PROM, in the context of acute-HCA with funisitis (AF MMP-8∶675.0 ng/ml [26.0–6142.6 ng/ml] vs. 416.8 ng/ml [0.4–5019.5 ng/ml]; umbilical cord plasma CRP: 969.3 ng/ml [7.6–6773.1 ng/ml] vs. 396.9 ng/ml [4.9–4885.5 ng/ml]; for each p<.05) (see Figure 4).
