Abstract

Aims: The frontal QRS-T (fQRST) angle is associated with worse cardiovascular outcome. The study aimed to assess the effect of reverse dipping pattern on f(QRST) angle in newly diagnosed masked hypertensive (MH) patients.

Materials and methods: Newly diagnosed 244 consecutive MH patients were included. According to dipping pattern, patients were grouped into three: dipper (n = 114), non-dipper (n = 106), and reverse dipper (n = 24) patterns. The f(QRST) angle, QT and corrected QT interval, and QT dispersion were measured from the 12-lead surface electrocardiogram and compared between groups.

Results: Of all, 51.2% (n = 125) were male. No gender difference was observed. Reverse dipper MH group had a significantly higher f(QRST) angle than the non-dipper and dipper MH groups (77.9 ± 8.6 vs. 32.4 ± 18.8 and 26.0 ± 18.5, respectively, p < .001). The cutoff value for f(QRST) angle of 51 predicts reverse dipping pattern (AUC: 0.84; 95% CI: 0.77-0.90; p < .001), with a sensitivity of 83% and a specificity of 78%.

Conclusion: This study revealed that f(QRST) angle is gradually increased starting from the dipper, non-dipper to reverse dipper masked hypertensives. The f(QRST) angle appears as an easy marker for the detection and risk stratification of hypertensive patients.

额叶QRS-T角可预测隐匿性高血压患者的反向倾斜模式。

目的:QRS-T (fQRST)正面角与较差的心血管预后相关。本研究旨在探讨反向倾斜模式对新诊断的隐匿性高血压(MH)患者f(QRST)角的影响。材料与方法:纳入244例连续新诊断的MH患者。根据浸液方式将患者分为浸液方式(n = 114)、不浸液方式(n = 106)和反浸液方式(n = 24) 3种。采用12导联体表心电图测量f(QRST)角、QT及校正QT间期、QT离散度，并进行组间比较。结果:男性占51.2% (n = 125)。没有观察到性别差异。反勺MH组的f(QRST)角明显高于非勺MH组和反勺MH组(分别为77.9±8.6 vs. 32.4±18.8和26.0±18.5)。结论:本研究显示，f(QRST)角从倒勺开始逐渐增大，非倒勺至倒勺掩盖高血压。f(QRST)角为高血压患者的检测和危险分层提供了简便的指标。

期刊介绍： Clinical and Experimental Hypertension is a reputable journal that has converted to a full Open Access format starting from Volume 45 in 2023. While previous volumes are still accessible through a Pay to Read model, the journal now provides free and open access to its content. It serves as an international platform for the exchange of up-to-date scientific and clinical information concerning both human and animal hypertension. The journal publishes a wide range of articles, including full research papers, solicited and unsolicited reviews, and commentaries. Through these publications, the journal aims to enhance current understanding and support the timely detection, management, control, and prevention of hypertension-related conditions. One notable aspect of Clinical and Experimental Hypertension is its coverage of special issues that focus on the proceedings of symposia dedicated to hypertension research. This feature allows researchers and clinicians to delve deeper into the latest advancements in this field. The journal is abstracted and indexed in several renowned databases, including Pharmacoeconomics and Outcomes News (Online), Reactions Weekly (Online), CABI, EBSCOhost, Elsevier BV, International Atomic Energy Agency, and the National Library of Medicine, among others. These affiliations ensure that the journal's content receives broad visibility and facilitates its discoverability by professionals and researchers in related disciplines.
