急性心肌梗死是最为常见的心血管危重症之一,随着社会老龄化和生活习惯的改变,急性心肌梗死(acute myocardial infarction,AMI)的发病率在逐步增加〔1〕。急性肾损伤(acute kidney injury,AKI)是AMI的常见并发症之一,发病率为10%~20%〔2-3〕。一旦AMI患者并发AKI,其住院时间会显著增加,且院内病死率和长期病死率均会显著增加,严重影响预后,因此对AKI的预防和及时治疗极为重要〔4-5〕。对AMI并发AKI患者的临床资 Acute myocardial infarction is one of the most common cardiovascular critically ill patients. With the aging of the society and the changes of living habits, the incidence of acute myocardial infarction (AMI) gradually increases [1]. Acute kidney injury (AKI) is a common complication of AMI, the incidence of 10% to 20% 〔2-3〕. Once AMI patients with AKI, their hospital stay will be significantly increased, and hospital mortality and long-term mortality will be significantly increased, seriously affecting the prognosis, and therefore AKI prevention and timely treatment is extremely important 〔4-5〕. AMI complicated with clinical data of patients with AKI
