Objective: To evaluate the prognostic value of hemoglobin(Hb) level and the China Acute Myocardial Infarction registry-ST segment elevation myocardial infarction(CAMI-STEMI) score in the prognosis of patients with STEMI after percutaneous coronary intervention(PCI).Methods: This study included 360 patients with STEMI who received PCI. The clinical characteristics of the patients, the CAMI-STEMI score, Hb and other biochemical indicators, severity of coronary artery disease and the incidence of major adverse cardiovascular and cerebral events(MACCE) during the follow-up period(30 days, 6 months) were recorded. The patients were divided into 3 groups according to the first Hb value after hospitalization.Results: The incidence of MACCE in the 3 groups at 30 days and 6 months after PCI increased with the decrease of Hb levels. Multivariate regression analysis showed that the CAMI-STEMI score was an independent predictor of MACCE incidence at 30 days after PCI(OR 1.225,95%CI 1.067-1.406,P=0.004). Anemia was an independent predictor of MACCE incidence at 6 months after PCI(OR 2.071,95%CI 1.178-3.461,P=0.011). The incidence of MACCE in patients without diabetes at 6 months after PCI was lower(OR 0.585,95%CI 0.363-0.944,P=0.028).Conclusion: The CAMI-STEMI score was an independent predictor of MACCE incidence at 30 days after PCI. Anemia was an independent predictor of MACCE in STEMI patients at 6 months after PCI, and the risk of MACCE in STEMI patients with anemia is significantly higher than that in STEMI patients with normal Hb levels. Diabetes is an independent predictor of MACCE in STEMI patients at 6 months after PCI. |
