Contrast-Induced Nephropathy: Update on the Use of Crystalloids and Pharmacological Measures

Table 1

Illustration of CIN risk qualities and scores assigned to each quality as proposed by Mehran and colleagues [6]. The risks for CIN and dialysis vary, depending on the cumulative score. Sixteen or more points are associated with an average CIN risk of 57.3% and a dialysis risk of 12.6% (see text).

Quality	Score
Hypotension	5
Intra-aortic ballon pump therapy	5
Chronic heart failure	5
Age > 75 years	4
Anemia	3
Diabetes	3
Contrast volume	Increasing with increasing volume
Serum creatinine > 1.5 mg/dL	4
eGFR < 60 ml/min/1.73 m^2	Increasing with decreasing eGFR
