Abstract

Background: Contrast-induced nephropathy (CIN) is a common complication caused by contrast agents. Especially in patients with chronic kidney disease (CKD), the risk of drug-induced nephropathy is even higher, causing immediate and long-term complications for the patient. However, patients with chronic kidney disease who have not received replacement therapy are often not fully and long-term monitored after using contrast agents. This study aims to assess renal damage in patients with chronic kidney disease who have not received replacement therapy, after coronary angiography and/or percutaneous coronary intervention at Bach Mai Hospital. Subjects and methods: Cross-sectional descriptive study on 110 patients with CKD who have not received replacement therapy and who received coronary angiography and/or percutaneous coronary intervention at Bach Mai Hospital from August 2024 to July 2025. Results: 18,2% of patients had CIN, of which the proportion of CIN patients requiring dialysis accounted for 15% of the total number with CIN. The rate of CIN increased gradually according to the stage of CKD, highest in the CKD5 group. In addition to the reduction of glomerular filtration rate before intervention, the use of vasopressors or reduction of urine volume before and after intervention increased the rate of patients with CIN. Conclusion: Chronic kidney disease increases the risk of CIN after coronary angiography and/or percutaneous coronary intervention.
