Influence of Contrast Media on Renal Function in Patients Undergoing CT Coronary Angiogram

Contrast media (CM) are essential for CT coronary angiogram (CTCA), but may affect renal function raising concerns about contrast-induced nephropathy. This study examines changes in serum creatinine, blood urea nitrogen, and glomerular filtration rate 48 hours after contrast exposure. A total of 40 patients (16 females, 24 males) undergoing CTCA were evaluated, and renal function was assessed using Cobas C111 analyzer, with eGFR calculated by the Jaffe method. The post contrast changes were analyzed to determine renal impairment risk. The findings contribute to a better understanding of CM effects on renal function, supporting clinical decision-making for high-risk patients. By stratifying patients based on their underlying comorbidities, the research may help guide safer clinical practices, including the use of preventive strategies for at-risk populations.
