Prognosis of Patients With Acute Coronary Syndrome Complicated With Renal Insufficiency(PACS-RI)

Several epidemiologic studies reported that patients with renal insufficiency might have increased cardiovascular disease-related mortality rates after Percutaneous coronary intervention (PCI) . The increased risk in this population may be related to the less use of standard guideline-based treatment and the resulting inability to perform PCI effectively. Recently, with the technology improvement and the progress in clinical trials, Chinese guidelines have made new recommendations about the patients with acute coronary syndrome(ACS) in different states of renal function. However, scant epidemiologic information exists on the prognosis of those patients, especially in Henan. And there is still some uncertainty whether those patients are using the latest guideline recommended treatment. This multicenter, prospective, observational study is aimed to evaluate the long prognosis in patients with acute coronary syndrome complicated with renal insufficiency, and to analysis its related factors that influence the outcomes.
