Diagnosis value of high density lipoprotein, retinol binding protein 4 associated with 24 h DCG in coronary heart disease with asymptomatic myocardial ischemia
纳入2022年5月—2023年5月收治的冠心病患者108例,观察发生SMI的患者与非SMI患者24 h DCG和高密度脂蛋白颗粒大小相关量化指标[高密度脂蛋白胆固醇/载脂蛋白A1(HDL‑c/ApoA1)]、RBP4变化情况,并分析这些指标的变化对患者发生SMI的诊断价值。
结果
2
经24 h DCG评估发现SMI组中阳性患者共有57例,诊断准确率为82.61%(57/69),发作时间段主要集中在6:00—11:59时间段;SMI组患者RBP4水平明显高于非SMI患者,而HDL‑c/ApoA1则明显低于非SMI患者(均

P

AUC
为0.891,明显高于各单项指标(

结论

24 h DCG对冠心病患者发生SMI具有一定的诊断价值,联合HDL‑c/ApoA1、RBP4诊断则可进一步提高诊断的价值。
Abstract
Objective
2
To investigate the changes of 24 h dynamic electrocardiogram (DCG)
high density lipoprotein (HDL) particle size and retinol binding protein 4 (RBP4) in patients with silent myocardial ischemia (SMI) of coronary heart disease (CHD)
and to evaluate their diagnostic value in SMI.
Methods
2
A total of 108 patients with CHD were enrolled from May 2022 to May 2023. The changes of 24 h DCG
HDL particle size and RBP4 in SMI patients and non‑SMI patients were observed
and the diagnostic value of these changes in SMI patients was analyzed.
Results
2
Fifty⁃seven SMI positive patients were evaluated by 24 h DCG
the diagnostic accuracy was 82.61%(57/69)
the onset time was mainly concentrated in 6:00⁃11:59
RBP4 level was significantly higher and HDL‑c/ApoA1 was significantly lower in SMI group than in non‑SMI group. Spearman analysis showed that SMI was positively correlated with RBP4 level in patients with CHD (
r
=0.450
P
<
0.05)
and there was a negative correlation between HDL‑c/ApoA1 and HDL‑c/ApoA1(
r
=-0.347
P
<
0.05). ROC curve analysis showed that the
AUC
of 24 h DCG
HDL‑c/ApoA1 and RBP4 for SMI diagnosis was 0.798
0.708 and 0.771
respectively. The
AUC
of combined diagnosis was 0.891
which was significantly higher than that of individual indexes (
P
<
0.05). The sensitivity and specificity of diagnosis were 0.899 and 0.795 respectively.
Conclusion
2
24 h DCG has certain diagnostic value for SMI in patients with coronary heart disease
and the combination of HDL‑c/ApoA1 and RBP4 can further improve the diagnostic value.
