摘要
目的
2
探讨动态心电图ST段改变、平面QRS-T夹角对冠心病心肌缺血的预测价值。
方法
2
选取2020年10月~2023年10月复旦大学附属中山医院厦门医院心血管内科收治的83例冠心病患者为研究对象，根据冠状动脉造影结果将其分心肌缺血组为A组（
n
=39）和无心肌缺血组为B组（
n
=44）。分析ST段、平面QRS-T夹角对冠心病心肌缺血的预测价值。
结果
2
两组一般资料中A组年龄、糖尿病、高血脂发生率高于B组，差异有统计学意义（
P
<
0.05）。ST段压低时，A组ST段改变、平面QRS-T夹角
>
90°占比高于B组，差异有统计学意义（
P
<
0.05）；ROC曲线显示：ST段改变、平面QRS-T夹角及联合预测的AUC、准确度、灵敏度、特异度分别为（0.680、67.47%、62.50%、74.29%）、（0.666、66.27%、62.22%、71.05%）、（0.797、70.72%、78.08%、83.33%），联合预测冠心病心肌缺血的预测价值高于单独预测（
P
<
0.05）。
结论
2
动态心电图ST段改变、平面QRS-T夹角对冠心病心肌缺血均有一定预测价值，但需要其他检查辅助提高确诊冠心病心肌缺血的准确率。
Abstract
Objective To explore the predictive value of dynamic electrocardiogram ST segment changes and planar QRS-T angle for myocardial ischemia in coronary heart disease. Methods 83 patients with coronary heart disease admitted to the Department of Cardiovascular Medicine of Xiamen Hospital affiliated with Zhongshan Hospital of Fudan University from October 2020 to October 2023 were selected as the study subjects. According to the results of coronary angiography
they were divided into myocardial ischemia group (
n
=39) and non myocardial ischemi
a group (
n
=44). Analyze the predictive value of ST segment and QRS-T angle in predicting myocardial ischemia in coronary heart disease.
Results
2
In the general data of the two groups
the age
diabetes and hyperlipidemia rate of group A were higher than those of group B
and the difference was statistically significant (
P
<
0.05). When the ST segment is depressed
the proportion of ST segment changes and QRS-T angle
>
90 ° in group A is higher than that in group B
and the difference is statistically significant (
P
<
0.05); The ROC curve shows that ST segment changes
QRS-T angle in the plane
and AUC
accuracy
sensitivity
and specificity of joint prediction are (0.680
67.47%
62.50%
74.29%)
(0.666
66.27%
62.22%
71.05%)
and (0.797
70.72%
78.08%
83.33%)
respectively. The predictive value of joint prediction of coronary heart disease myocardial ischemia is higher than that of individual prediction (
P
<
0.05).
Conclusions
2
The changes in ST segment and QRS-T angle of dynamic electrocardiogram have certain predictive value for myocardial ischemia in coronary heart disease
but other examinations are needed to assist in improving the accuracy of diagnosing myocardial ischemia in coronary heart disease.
