China patients in end stage renal disease receiving maintenance dialysis have a high risk of cardiovascular disease (CVD), with a prevalence of 45.5% approximately, and coronary artery disease (CAD) has been identified as the most common one. It remains unclear that what their treatment status is and whether this group of patients can benefit from revascularization in China. The investigators plan to recruit around 30 hospitals from 7 regions as study centers, which represent different levels of economic development in Mainland China. The detailed information includes demographics, medical history, coronary angiogram, in-hospital treatment and procedures, short-term and long-term outcomes. The aim of the study is to provide the real world knowledge about current status of coronary revascularization and prognosis in patients with CAD and dialysis.
