Differing Behavior of Plasma Pentraxin3 and High-Sensitive CRP at the Very Onset of Myocardial Infarction with ST-segment Elevation

Although pentraxin3 (PTX3) has been reported as marker of more directly reflect the vascular inflammatory status than short pentraxin including high-sensitive CRP (hs-CRP), detailed difference in blood levels between PTX3 and hs-CRP at the onset of ST-segment elevation myocardial infarction (STEMI) are not fully investigated. Blood levels of pentraxins (PTX3 and hs-CRP) in 20 patients with early arrival of STEMI (2.9 ± 2.2 hours after onset) were measured at baseline, 24, 48, 72 and 120 hours after primary percutaneous coronary intervention (PCI). Also, the blood levels in infarct-related artery (IRA) were measured by thrombus aspiration during PCI. Samples of control (not myocardial infarction) with normal coronary artery (n=10) were drawn from both coronary and peripheral arteries during diagnostic coronary angiography. At baseline, the levels of PTX3 in both femoral and coronary artery in STEMI were significantly higher than those in control, but the hs-CRP did not different between STEMI and control. The level of both PTX3 and hs-CRP did not different between femoral artery and IRA in STEMI patients at baseline. Systemic level of PTX3 peaked 24 hours (p=0.01) followed by the hs-CRP that peaked 48 hours (p<0.01) after the PCI. PTX3 had appeared earlier than hs-CRP in the systemic circulation in the STEMI patients, but they may not be locally released from the IRA.
