纳入标准:

Inclusion criteria

排除标准:

1.同期进行经皮冠状动脉介入治疗(PCI)的杂交手术患者; 2.同期行其他心脏手术:如,心脏瓣膜置换/成形、室壁瘤切除、主动脉手术等重大心外手术的患者; 3.术前发生过心脏骤停并进行复苏的患者; 4.对于构建模型所必需的核心变量严重缺失或无法获取的病例; 5.病历记录无法明确判断是否发生中转体外循环的病例。

Exclusion criteria:

1. Patients undergoing hybrid surgery including percutaneous coronary intervention (PCI) at the same time; 2. Patients undergoing other major cardiac surgeries simultaneously, such as heart valve replacement/repair, ventricular aneurysm resection, aortic surgery, etc. 3. Patients who experienced cardiac arrest before the operation and underwent resuscitation; 4. Cases with severe lack or inability to obtain the core variables necessary for model construction; 5. Cases whose medical records cannot clearly determine whether they underwent conversion to cardiopulmonary bypass.
