ABSTRACT

Objective

Left atrial (LA) function is an important predictor of adverse cardiovascular outcomes in patients with hypertension (HT). Therefore, recognition of subtle LA dysfunction in the early stages of HT is essential for controlling modifiable variables. Several electrocardiographic and echocardiographic parameters have been studied to show early LA dysfunction. The goal of this study was to investigate the relationship between newly defined morphology‐voltage‐P wave duration electrocardiography (MVP ECG) score and early LA dysfunction in hypertensive patients.

Materials and methods

Eighty-nine hypertensive patients were included in this study. Based on speckle tracking echocardiography results, the patients were divided into two groups: 67 patients with normal LA function were included in Group 1, and 22 patients with abnormal LA function in Group 2.

Results

Age, diabetes mellitus history, duration of HT history, left ventricular mass index, E/Em, and MVP ECG score values were statistically significant between the two groups. Based on the results of the multivariate logistic regression test, duration of HT history, E/Em, and MVP ECG score were determined as independent predictive parameters for early LA dysfunction in hypertensive patients.

Conclusion

In conclusion, MVP ECG score assessment could be a novel approach to detect early LA dysfunction in hypertensive patients.

形态-电压-P波时长心电图评分在预测高血压患者早期左心房功能障碍中的作用

摘要

客观的

左心房 (LA) 功能是高血压 (HT) 患者心血管不良结局的重要预测指标。因此，识别 HT 早期阶段的细微 LA 功能障碍对于控制可修改变量至关重要。已经研究了几种心电图和超声心动图参数以显示早期 LA 功能障碍。本研究的目的是调查新定义的形态-电压-P 波持续时间心电图 (MVP ECG) 评分与高血压患者早期 LA 功能障碍之间的关系。

材料和方法

本研究纳入了 89 名高血压患者。根据斑点追踪超声心动图结果，将患者分为两组：第 1 组 67 例 LA 功能正常患者，第 2 组 22 例 LA 功能异常患者。

结果

年龄、糖尿病史、HT病史持续时间、左心室质量指数、E/Em和MVP心电图评分值在两组间有统计学意义。基于多变量逻辑回归检验的结果，将 HT 病史持续时间、E/Em 和 MVP 心电图评分确定为高血压患者早期 LA 功能障碍的独立预测参数。

结论

总之，MVP ECG 评分评估可能是一种检测高血压患者早期 LA 功能障碍的新方法。
