摘要:

目的 通过基于心肺运动试验(CPET)的测试数据和患者的一般临床资料,对稳定型冠心病患者进行心脏康复风险分层,区分出心脏康复的低危和高危患者。

方法 连续纳入2014年12月至2018年12月本院冠心病数据库中冠脉造影术前行CPET检查的稳定型冠心病患者114例。使用LASSO回归进行变量筛选;使用Logistic回归建立评估模型,使用R软件的RMS包绘制评估模型的列线图;通过R软件的ROCR包绘制受试者工作特征曲线,计算曲线下面积(AUC)。

结果 根据LASSO回归分析,确定7个预测因素:冠脉造影结果、最大二氧化碳通气当量(EqCO2max)、淋巴细胞计数、空腹血糖水平、心肌酶阳性、血同型半胱氨酸和血尿素氮水平。结合临床经验及权重分析,最终纳入冠脉造影结果、EqCO2max、淋巴细胞计数和空腹血糖水平4个因素进行Logistic回归建模;模型的AUC值为0.875,对结局事件有良好预测能力。

结论 EqCO2max和淋巴细胞计数为稳定型冠心病患者心脏康复风险分层的主要预测因素,可用于识别稳定型冠心病心脏康复的高危患者;基于CPET和实验室检查建立的稳定型冠心病患者心脏康复风险分层评估模型,可以为稳定型冠心病患者心脏康复的风险评估提供帮助。

Abstract:

Objective To create a prediction model that could be used to stratify the risk of cardiac rehabilitation in patients with stable coronary artery disease by using test data based on cardiopulmonary exercise testing (CPET) and general clinical data.

Methods A total of 114 patients with stable coronary artery disease were consecutively enrolled from the Cardiology Coronary Artery Disease Database of our hospital from December, 2014 to December, 2018, all the patients underwent CPET before coronary angiography. LASSO was used for feature selection. A nomogram was formulated based on the results of multivariate Logistic regression analysis using the RMS package of R. The predictive power was assessed with Receiver Operating Characteristic Curve.

Results Seven predictors were identified based on LASSO: coronary angiography results, the maximum value of ventilatory equivalent for carbon dioxide (EqCO2max), lymphocyte count, fasting blood glucose levels, cardiac muscle enzyme positivity, blood homocysteine and blood urea nitrogen levels. Combined with clinical experience and weighting analysis, the final four factors were included for Logistic regression modeling: coronary angiography results, EqCO2max, lymphocyte count and fasting blood glucose levels. The area under the curve was 0.875 for the model.

Conclusion EqCO2max and lymphocyte count are key predictors for stable coronary heart disease and can be used to identify patients at high risk for cardiac rehabilitation. A risk stratification model based on CPET and laboratory tests can be used to assess risk stratification for cardiac rehabilitation in patients with stable coronary artery disease.
