Incidence and risk factors for contrast-induced nephropathy after angioplasty: an observational retrospective study.

ABSTRACT:

Background

Contrast-induced nephropathy (CIN) is a complication of iodinated contrast media use that can lead to worsening of renal function, increased morbidity and mortality, and the need for renal replacement therapy.

Objectives

To evaluate the incidence of CIN after angioplasty and identify associated factors, including variations in creatinine, glomerular filtration rate (GFR), contrast volume, procedure time, and comorbidities.

Methods

Retrospective study of 305 patients undergoing angioplasty. Clinical and laboratory variables, including serum creatinine and GFR before and after the procedure, were analyzed. CIN was defined as an absolute increase in creatinine ≥ 0.3 mg/dL or a relative increase ≥ 50% within 48 hours. Logistic regression was applied to identify
