After adjusting for age, sex, history of hypertension, history of PCI, history of CABG, history of CKD, Killip classification, high-sensitivity C-reactive protein, and estimated glomerular filtration rate, the cumulative incidences of MACEs (adjusted HR, 1.269, 95% CI, 1.023–1.576, log rank P = 0.031) and all-cause death (crude HR, 1.355, 95% CI, 1.011–1.815, log rank P = 0.042) were lower in the non-DM group than in the DM group after PSM. This evidence concerns the gene CRP and Hypertension.
