Abbreviations. AUC = the area under receiver operating characteristic curve; MACCE = the main adverse cardiac and cerebrovascular events; STEMI = ST Elevation Myocardial Infarction; PCI = percutaneous coronary intervention; CAMI-STEMI score = the China Acute Myocardial Infarction registry-ST Elevation Myocardial Infarction score.
It showed that the haemoglobin level and CAMI-STEMI score had a high predictive value for MACCE in STEMI patients within 30 days after PCI (AUC 0.604, 0.614) and that the haemoglobin level combined with CAMI-STEMI score could improve the predictive value of MACCE in STEMI patients within 30 days after PCI (AUC 0.639). In contrast, CAMI-STEMI score had a poor predictive value for MACCE in STEMI patients at 1 year (AUC 0.538).
