Survival of STEMI patients according to renal function. a Kaplan–Meier models of STEMI patients according to their renal function at index. Within nine years follow-up, the Kaplan–Meier survival estimates decreased from 58% without known CKD (no CKD) to 10% in STEMI patients on dialysis (CKD stage 5d). b Adjusted survival plot determined by Cox regression analysis for STEMI patients according to their renal function. Age, sex, CKD stage at index, and the patient's risk profile (hypertension, dyslipidemia, obesity, nicotine abuse, diabetes mellitus, chronic kidney disease, atrial fibrillation and/or flutter, peripheral artery disease, chronic heart failure, cerebrovascular disease, cancer, previous acute myocardial infarction, previous stroke, previous percutaneous intervention, previous coronary artery bypass grafting, previous valve replacement) were included in the model. The adjusted survival markedly decreased from 52% for patients without CKD (no CKD) and with CKD stage 2 (both curves overlap) to 27% for patients with dialysis-dependent CKD (CKD stage 5d). CKD denotes chronic kidney disease; STEMI, ST-elevation myocardial infarction
