We developed a rapid evaluation scale for pericardiectomy through a 12-lead electrocardiogram (ECG), in order to improve the diagnostic accuracy of pericardiectomy of tuberculous constrictive pericarditis.
In this study, 262 patients with tuberculous constrictive pericarditis (102 patients) and non-tuberculous constrictive pericarditis (160 patients) were selected by convenience sampling method as participants in Hangzhou Red Corss Hospital from January 2018 to April 2023. The expert validity analysis was carried out by cross-sectional investigation combined with the results of the previous expert questionnaire to establish 12-lead ECG-based the rapid evaluate scale for pericardiectomy of tuberculous constrictive pericarditis. Cronbach'α coefficient and Spearman-Brown coefficient were used for the internal consistency reliability of the scale. Exploratory factor analysis was used for structural validity. Receiver operating characteristic (ROC) was used to analyze the sensitivity and specificity of this scale.
After preliminary verification, the cronbach'α coefficient and Spearman-Brown coefficient were 0.830 and 0.800, respectively. Three factors with feature roots greater than 1.0 were extracted by principal component analysis and maximum variance orthogonal rotation, and the cumulative contribution rate was 57.77%. Each loading factor ranges from 0.427 to 0.863. The sensitivity of the scale was 96.1%, the specificity was 96.9% and the Yorden Index was 93.0%.
The 12-lead ECG-based rapid evaluation scale for pericardiectomy of tuberculous constrictive pericarditis has high sensitivity, specificity and accuracy, and has certain scientific research and clinical application value.
我们通过12导联心电图（ECG）开发了一种心包切除术快速评估量表，以提高结核性缩窄性心包炎心包切除术的诊断准确性。
本研究采用便利抽样法，选取2018年1月至2023年4月在杭州市红十字会医院就诊的262例结核性缩窄性心包炎患者（102例）和非结核性缩窄性心包炎患者（160例）作为研究对象。采用横断面调查结合前期专家问卷结果进行专家效度分析，建立基于12导联心电图的结核性缩窄性心包炎心包切除术快速评估量表。采用Cronbach'α系数和Spearman-Brown系数对量表的内部一致性信度进行分析。采用探索性因素分析对量表的结构效度进行分析。采用受试者工作特征曲线（ROC）分析该量表的敏感性和特异性。
经初步验证，Cronbach'α系数和Spearman-Brown系数分别为0.830和0.800。通过主成分分析和最大方差正交旋转提取出3个特征根大于1.0的因子，累积贡献率为57.77%。各载荷因子范围为0.427～0.863。该量表的敏感性为96.1%，特异性为96.9%，约登指数为93.0%。
基于12导联心电图的结核性缩窄性心包炎心包切除术快速评估量表具有较高的敏感性、特异性和准确性，具有一定的科研和临床应用价值。
