Contrast-induced Nephropathy: Incidence,Risk Factors,Effective Prevention and Management Method

Chinese PLA General Hospital10,000 enrolled

Overview

This review article have included about ten thousand patients undergoing percutaneous coronary intervention (PCI), aim to identify the incidence of CIN in actual, find some new risk factors and the protecting methods for these factors.

About ten thousand patients undergoing percutaneous coronary intervention (PCI) from 2010 to 2015 are included in this study. We collect the data about the SCr of the patients before and after percutaneous coronary intervention, and define CIN as an increase in SCr of 0.5 mg/dl or 25% from baseline between 48 and 72 h after contrast medium exposure. Besides we obtain the data including clinical characteristics, laboratory data (blood and urine tests) for all the patients. The statistical analysis will find some new risk factors.
