Anaemia was an independent predictor of MACCE incidence at 1 year after PCI (HR:1.521; 95%CI:0.963-2.397; P=0.071).A high haemoglobin level was an independent predictor of MACCE incidence at 1 year after PCI (HR:0.456; 95%CI:0.222-0.937; P=0.033). The incidence of MACCE in patients with hypertension at 1 year after PCI was also higher (HR:1.453; 95%CI:1.007-2.096; P=0.046). The incidence of MACCE in patients with diabetes mellitus at 1 year after PCI was higher (HR:1.420; 95%CI:0.980-2.058; P=0.063). The incidence of MACCE in patients with thrombus aspiration during PCI at 1 year after PCI was lower (HR:0.685; 95%CI:0.489-0.961; P=0.028).
