Contrast-induced nephropathy after elective percutaneous coronary interventions

The study consisted in a retrospective analysis of the frequency of contrast-induced nephropathy (CIN) and the effectiveness of its prevention after elective endovascular interventions on the coronary arteries in patients with stable coronary artery disease (CAD). Despite ongoing prevention, acute kidney injury was found in 24 patients (16.8%) in the group of patients with a predominance of moderate and high risk CIN (average Mehran Risk Score = 9). The increase in serum creatinine in patients with CIN after endovascular intervention was 42.5%; glomerular filtration rate decreased by 31%; and creatinine clearance decreased by 29.05%. Overall CIN was benign as the main indicators of renal function returned to baseline levels during the hospital period and did not require renal replacement therapy in any of the patients who developed CIN.
