Abstract Objective To assess the association of serum procalcitonin (PCT) level with no- reflow phenomenon during primary percutaneous coronary intervention(PCI) in patients with acute myocardial infarction(AMI). Methods 360 consecutive patients with AMI who underwent primary PCI were enrol ed. They were divided into no- reflow group and reflow group. Age, diabetic history, Syntax score, the time interval from symptom onset to bal oon, white blood cel count, serum PCT and hs- CRP were compared between the two groups. Multivariate logistic regression analysis was performed to determine the factors influencing no- reflow during primary PCI. Results Age,the percentage of diabetes,white blood cel count,serum PCT,hs- CRP levels, Syntax score as wel as the time interval from symptom onset to bal oon were significantly higher in no- reflow group than in reflow group (al P<0.05). PCT and the time interval from symptom onset to bal oon were significantly correlated with no- reflow during primary PCI of AMI (al P<0.05). Conclusion The elevated serum PCT is associated with coronary no- reflow during primary PCI of AMI.
