Background-The Mehran Risk Score (MRS) has been demonstrated to be clinically useful for prediction of contrast-induced nephropathy (CIN) after nonurgent percutaneous coronary intervention. We aim to validate the MRS in the setting of Primary percutaneous coronary intervention for prediction of both CIN and short- and long-term clinical outcomes. METHODS AND RESULTS: <0.001) when compared with the low-risk group and was also increased in the high-risk group (HR, 6.31; 95% CI, 3.28 to 12.14; P<0.001) and medium-risk group (HR, 3.18; 95% CI, 1.83 to 5.51; P<0.001). Similarly, an increasing effect was seen across MRS strata for major cardiovascular and cerebrovascular events both in the very high-risk group (HR, 3.79; 95% CI, 2.27 to 6.6.32; P<0.001), high-risk group (HR, 1.90; 95% CI, 1.31 to 2.75; P=0.001), and medium-risk group (HR, 1.42; 95% CI, 1.10 to 1.85; P=0.007). In addition, the HR for rehospitalization increased with the increasing RC groups (HR, 3.32; 95%CI, 1.96 to 5.63; P<0.001; HR, 3.11; 95% CI, 1.35 to 7.20; P=0.008; HR, 7.73; 95% CI, 2.97 to 20.10; P<0.001, respectively). The odds ratio for CIN was 2.84 (95% CI, 1.16 to 6.92; P=0.021) in the very high RC group, 1.33 (95% CI, 0.68 to 2.61; P=0.398) in the high RC group, and 1.10 (95% CI, 0.67 to 1.79; P=0.699) in the medium RC group, as compared with the lower one. Conclusions-The MRS may be applied in the primary angioplasty setting population and is able to predict CIN and to stratify patients for poor clinical outcomes both in the short- and long-term follow-up.
