| 目的 分析四维自动化定量超声联合心电图心率变异性（HRV）预测急性心肌梗死（AMI）患者预后的价值。方法 选取2020年3月至2022年3月该院收治的AMI患者83例，均行四维自动化定量超声、心电图检查，依据预后情况分为发生主要不良心血管事件（MACE）组、未发生MACE组，分析两组的超声参数、HRV参数差异及与MACE发生率的相关性，评估两种影像学方法联合对预后的预测价值。结果 发生MACE组的左房排空容积（LAEV）、左房被动射血分数（LAPEF）、左房主动射血分数（LAAEF）及左室射血分数（LVEF）、径向应变（GRPS）等低于未发生MACE组，而左房最大容积指数（LAVImax）高于未发生MACE组（P＜0.05）；发生MACE组的全部窦性心搏RR间期的标准差（SDNN）、RR间期平均值的标准差（SDANN）、相邻RR间期差值的均方根（RMSSD）、低频（LF）/高频（HF）、相邻RR间期相差＞50 ms的个数占总窦性心搏个数的百分比（PNN50）低于未发生MACE组（P＜0.05）；LAEV、LAPEF、LVEF、GAPS、SDNN与MACE事件发生率呈负相关，LAVImax与MACE事件发生率呈正相关（P＜0.05）；LAEV、LAPEF、LVEF、LAVImax、GAPS、SDNN联合预测AMI患者预后的曲线下面积为0.841，敏感度、特异度分别为0.81、0.76，高于各项参数单独预测。结论 四维自动化定量超声联合心电图HRV对AMI患者预后有较高预测价值，值得在临床推广实践。 |

| Abstract: |
| Objective To analyze the prognostic value of four-dimensional ultrasound automatic quantitative analysis combined with heart rate variability (HRV) detected by electrocardiography in patients with acute myocardial infarction (AMI). Methods A total of 83 patients with AMI admitted to the hospital from March 2020 to March 2022 were selected. All patients underwent four-dimensional ultrasound examination and electrocardiography. They were divided into the major adverse cardiovascular events (MACE) group and the non-MACE group according to the prognosis. Ultrasound parameters and HRV in the two groups were comparatively analyzed, and their correlation with the incidence of MACE was analyzed. The prognostic value of the combination of the two imaging methods was evaluated. Results Left atrial emptying volume (LAEV), left atrial passive ejection fraction (LAPEF), left atrial active ejection fraction (LAAEF), left ventricular ejection fraction (LVEF), and global radial peak strain (GRPS) ,etc in the MACE group were lower than those in the non-MACE group. The maximum left atrial volume index (LAVImax) was higher than that in the non-MACE group (P<0.05). The standard deviation of normal RR intervals (SDNN), the standard deviation of the averages of R-R intervals (SDANN), the root mean square of successive RR interval differences (RMSSD), low frequency (LF)/high frequency (HF), and the percentage of RR intervals with >50ms variation (PNN50) in the MACE group were lower than those in the non-MACE group (P<0.05). LAEV, LAPEF, LVEF, GAPS and SDNN were negatively correlated with the incidence of MACE, while LAVImax was positively correlated with the incidence of MACE (P<0.05). The area under the curve, sensitivity and specificity of LAEV, LAPEF, LVEF, LAVImax, GAPS, and SDNN in combination to predict the prognosis of patients with AMI were 0.841, 0.81 and 0.76, all of which were higher than single prediction. Conclusion Four-dimensional ultrasound automatic quantitative analysis combined with HRV detected by electrocardiography is of high prognostic value in patients with AMI. |
