Evaluation of contrast induced nephropathy related risk factors and long-term results.

INTRODUCTION: We aimed to evaluate the frequency of contrast induced nephropathy (CIN), its relationship with accepted risk factors and long-term renal outcomes in patients who underwent coronary angiography (CAG).

METHODS: All patients who underwent CAG between April 2020 and April 2021 were retrospectively evaluated. CIN was defined as characteristic increase in serum creatinine after CAG.

RESULTS: CIN developed in 50 (5.4%) of 934 patients. The CIN rate was found to be statistically significantly higher in patients with diabetes, hypertension, heart failure and those using diuretics. Pre-procedural hemoglobin, albumin and GFR were found to be independent risk factors for CIN. After discharge, the urea and creatinine values of the patients who developed CIN were significantly higher than those who did not.

CONCLUSION: We concluded that in order to reduce the development of CIN, hemoglobin and albumin levels should be evaluated with renal functions before the procedure and they should be kept within normal limits.
