Recent studies showed that pentraxin-3 (PTX3) was related to the early diagnosis and prognosis of coronary heart disease. This study aimed to investigate the dynamical change of PTX3 after primary percutaneous coronary intervention (pPCI) in STEMI patients and its prognostic value.Patients and methods: In this prospective cohort study, a total of 350 patients were enrolled. The plasma level of PTX3 was measured at admission, 24-hour and 5-day after pPCI. The primary endpoint was the incidence of major adverse cardiac cerebral events (MACCEs) during 1-year follow-up.Results: Compared with the admission, PTX3 levels were significantly increased at 24 hours, and decreased at 5 days after pPCI in the whole cohort. PTX3 levels at these three time points were not significantly different between the patients with and without MACCEs. Notably, the change in PTX3 from admission to post-pPCI 24-hour (ΔPTX3) was higher in patients with MACCEs (112.83 vs 17.94 ng/dl, P = 0.001). The ROC curves showed that the cut-off value was 29.22 ng/dl and the area under curves was 0.622 (95% CI: 0.554– 0.690, p = 0.001). Multivariable cox regression models revealed that the high ΔPTX3 group was an independent predictor of MACCEs (adjusted HR = 2.010, 95% CI = 1.280– 3.186, p = 0.003). The higher ΔPTX3 group had significantly higher incidences of revascularization (HR = 2.094, 95% CI: 1.056– 4.150, p = 0.034) and composite MACCEs (HR = 2.219, 95% CI: 1.425– 3.454, p < 0.001). However, the change of PTX3 level from admission to post-pPCI 5-day had no independently predictive value.Conclusion: The higher increase of PTX3 level 24-hour after pPCI appeared to have a potential value in independently predicting the incidence of 1-year MACCEs in STEMI patients, especially for coronary revascularization.Keywords: pentraxin-3, primary percutaneous coronary intervention, ST-segment elevation myocardial infarction, prognosis |
