研究目的:

构建并验证老年急性冠脉综合征患者PCI术后6个月主要不良心血管事件的风险预测模型,为临床精准风险分层和个体化护理干预提供依据。  

Objectives of Study:

To construct and validate a risk prediction model for major adverse cardiovascular events within 6 months after PCI in elderly patients with acute coronary syndrome, so as to provide evidence for clinical precise risk stratification and individualized nursing intervention.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄≥60岁(依据世界卫生组织及联合国关于老年人划分的标准,并结合国内老年心血管疾病研究惯例)。 2.于2022年1月1日至2024年12月31日期间就诊于本院心血管内科。 3.在本次住院期间成功接受经皮冠状动脉介入治疗(包括球囊扩张、支架植入或两者兼有)。 4.具有完整的电子病历资料,能够获取计算GRACE评分及模型构建所需的核心变量。

Inclusion criteria

1.Age >= 60 years old (according to WHO/UN standards for the elderly, combined with domestic cardiovascular research conventions); 2. From January 1st, 2022 to December 31st, 2024, they were treated in the Department of Cardiology of our hospital; 3. Successfully received percutaneous coronary intervention (including balloon dilatation, stent implantation or both) during this hospitalization; 4. Have complete electronic medical record data, and be able to obtain the core variables required for calculating grace score and model construction.

排除标准:

1.危重状态:因心源性休克、心脏机械并发症(如室间隔穿孔、乳头肌断裂)等危重状态入院,或预期生存时间极短(<24小时)。 2.严重合并症:合并恶性肿瘤(预期生存期<1年)、终末期肝病、严重血液系统疾病或免疫系统疾病。 3.院内死亡:本次住院期间行PCI术后发生院内死亡者。 4.关键数据缺失:临床关键资料(如左心室射血分数(LVEF)、冠脉病变血管数、肌钙蛋白峰值等)缺失,导致无法用于模型分析者。 5.非首次入院:因同一疾病诊断在统计时间窗内重复入院者(仅纳入首次入院记录)。 6.经研究者判断认为不适合参与本研究的患者。

Exclusion criteria:

1. critical state: hospitalized due to cardiogenic shock, cardiac mechanical complications (such as ventricular septal perforation, papillary muscle rupture) and other critical states, or the expected survival time is very short (<24 hours); 2. severe complications: malignant tumor (expected survival time<1 year), end-stage liver disease, severe hematological system disease or immune system disease; 3. in hospital death: in hospital death occurred after PCI during this hospitalization; 4. lack of key data: the clinical key data (such as left ventricular ejection fraction (LVEF), the number of coronary artery lesions, troponin peak, etc.) are missing, so they cannot be used for model analysts; 5. non first admission: repeat admission within the statistical time window due to the same disease diagnosis (only included in the first admission record); 6. patients who are judged by the investigator as unsuitable for participating in this study.

测量方法:

将数据集按7:3随机分为训练集和验证集,训练随机森林及XGBoost等模型。在验证集中计算ROC曲线的AUC,并根据最大约登指数确定阈值,计算敏感度、特异度、PPV、NPV。采用R软件实现。

Measure time point of outcome:

6 months after PCI

Measure method:

The dataset is randomly split into training and validation sets with a 7:3 ratio. Random Forest and XGBoost models are trained. In the validation set, the AUC of the ROC curve is calculated, and the threshold is determined based on the maximum Youden index, then sensitivity, specificity, PPV, and NPV are computed. R software is used for implementation.
