Aims: To explore the ability of the ACEF score to predict the incidence of contrast-induced nephropathy (CIN) in patients undergoing coronary angiography with or without percutaneous coronary intervention., Methods: A total of 706 patients undergoing coronary angiography ± percutaneous coronary intervention (PCI) between March 2011 and October 2011 were analyzed. CIN using different definitions was termed as CINnarrow (rise in serum creatinine ≥0.5 mg/dl) and CINbroad (rise in serum creatinine ≥0.5 mg/dl and/or ≥25% increase in baseline serum creatinine)., Results: The mean ACEF score was 1.5 ± 0.6. Overall incidences of CINnarrow and CINbroad were 5.5% and 13.6%, respectively. There was a significant gradient in the incidence of CINnarrow (2.9%, 3.9%, 10.6% in the I, II, and III tertiles, respectively, P < 0.001) and CINbroad (9.1%, 14.2%, 17.9% in the I, II, and III tertiles, respectively, P = 0.021) across increasing ACEF tertiles. The ACEF score was independently associated with the risk of CINnarrow (adjusted odds ratio [OR] 1.6, 95% confidence interval [CI] 1.0-2.7; P = 0.047). Discrimination was more satisfactory when using the ACEF as a predictor of CINnarrow (c-statistic 0.71, 95% 0.63-0.79)., Conclusion: The ACEF score is an independent and potentially useful predictor of CIN defined as rise in serum creatinine ≥0.5 mg/dl.

The aim of this study was to report on the 30-day and 1-year outcomes of percutaneous mitral valve repair with the MitraClip technique in patients with grade ≥3+ mitral regurgitation (MR) at high risk for conventional surgical therapy enrolled in the prospective Getting Reduction of Mitral Insufficiency by Percutaneous Clip Implantation (GRASP) registry. Acute device success was defined as residual MR ≤2+ after clip implantation. The primary safety end point was the rate of major adverse events at 30 days. The primary efficacy end point was freedom from death, surgery for mitral valve dysfunction, or grade ≥3+ MR at 30 days and 1 year. A total of 117 patients were treated. Eighty-nine patients (76%) presented with functional MR and 28 patients (24%) with organic MR. Acute device success was observed in all patients. Device implantation time significantly diminished with experience and varied significantly between cases with 1 versus ≥2 clips. No procedural mortality was recorded. Major adverse events occurred in 4 patients at 30 days (4.3%). Deterioration to MR ≥3+ was recorded in 25% of patients with degenerative MR and 7% of those with functional MR at 1 year. No surgery for mitral valve dysfunction occurred within 1 year. Freedom from death, surgery for mitral valve dysfunction, or grade ≥3+ MR was 96.4% and 75.8% at 30 days and 1 year, respectively. No significant differences were noted in the primary efficacy end point between patients with degenerative MR and those with functional MR. In conclusion, percutaneous mitral valve repair with the MitraClip technique was shown to be safe and reasonably effective in 117 patients from a real-world setting., (Copyright © 2013 Elsevier Inc.
