Construction and validation of nomogram model for risk of perioperative cardiovascular events in patients with colorectal cancer recovering from AMI

Data from this study were obtained from the Chinese Colorectal Cancer surgery Database (CCCD). The CCCD was established by the Colorectal Surgery Group of the Surgery Branch of the Chinese Medical Association. It involves the participation of 73 medical centers across 26 provinces, autonomous regions, and municipalities. Since its initiation in March 2018, the database has incorporated information from approximately 100,000 patients. The CCCD adopts a hospital-centered entry model for surgical cases of CRC. It contains relatively comprehensive registration information encompassing a total of 77 variables including preoperative comorbidities and surgical complications. In this study, we used the keyword "history of AMI" to screen CCCD cases from March 2018 to March 2023. In total, 196 patients met the inclusion criteria. Clinical data were retrospectively analyzed and the patients were divided into perioperative cardiovascular events (PCE) and non-PCE groups according to the occurrence of PCE (occurrence of PCE=1, absence of PCE=0). This research study was conducted retrospectively from data obtained for clinical purposes.

本研究的数据来源于中国结直肠癌手术数据库（Chinese Colorectal Cancer Surgery Database，CCCD）。该数据库由中华医学会外科学分会结直肠外科学组建立，吸纳了全国26个省、自治区、直辖市的73家医疗中心参与。自2018年3月启动以来，该数据库已收录约10万例患者的相关信息。CCCD采用以医院为中心的结直肠癌（Colorectal Cancer，CRC）手术病例录入模式，涵盖术前合并症、手术并发症等共计77项较为全面的登记变量。本研究以“急性心肌梗死病史”为关键词，筛选2018年3月至2023年3月期间CCCD内的病例，最终共有196例患者符合纳入标准。研究团队对该批临床数据进行回顾性分析，并根据围术期心血管事件（perioperative cardiovascular events，PCE）的发生情况将患者分为两组：PCE发生组（赋值为1）与非PCE发生组（赋值为0）。本研究为基于临床用途获取数据开展的回顾性研究。
