Long-time renal impairment. Patients were divided in four groups with different changes in renal function: One group with improved renal function (creatinine < 0.8 times baseline), one group with stable renal function (creatinine 0.8–1.2 times baseline), one group with moderately impaired renal function (creatinine 1.2–1.5 times baseline) and one group with severely impaired renal function (creatinine > 1.5 times baseline or renal replacement therapy); A. The proportion of patients at discharge; B. The proportion at follow-up (161 ± 87 days); CKD — chronic kidney disease.
