Risk factors for contrast induced nephropathy: A study among Italian patients

摘要

This study aimed to make a profile of patients at highest risk of developing contrast induced nephropathy (CIN) in order to take appropriate prevention measures. 591 patients undergoing coronary procedures were divided into two groups: patients with (CIN-group) and without (no-CIN) an increase in creatinine level equal or more than 25% from baseline values within 24-48 h after the coronary procedure. All patients underwent an accurate anamnesis, objective exam, hematochemical measurements, and diagnostic exams. The results of this study while confirming that, average age (p = 0.01), diabetes mellitus (p < 0.0001), base line renal insufficiency (p = 0.0001), diuretic therapy (p = 0.002), higher contrast doses (p = 0.01), are associated with a higher risk of contrast-induced nephropathy, also demonstrated that both clinical (p = 0.01) and subclinical (p < 0.0001) atherosclerosis, and higher preprocedural high sensitive C-reactive protien levels (hs- CRP) (p = 0.02) are risk factors for CIN.
