Excessive hypertensive response to exercise testing is associated with adverse cardiovascular events such as left ventricular hypertrophy and atrial fibrillation (AF). In this study, we examined the relationship between electromechanical delay and excessive hypertensive response to exercise testing.
Twenty-five people who had a hypertensive response to the exercise stress test and 28 people who were similar in age and gender with a normal blood pressure response in the exercise stress test as the control group were included in the study.
There was no statistical difference between the study groups in blood pressure holter values, conventional echocardiography findings, and exercise stress test findings. Lateral PA-TDI time (the time from the beginning of the P wave measured by tissue Doppler imaging to the beginning of the A' wave), left atrial electromechanical delay, and interatrial electromechanical delay were observed to be significantly longer in the hypertensive response group to exercise stress test compared with the control group (74.0±6.3 vs. 68.8±5.7, p=0.003; 24.7±7.0 vs. 19.6±7.1, p=0.013; 36.8±8.5 vs. 30.6±6.6, p=0.003, respectively).
Early detection of electromechanical delay non-invasively may be useful in this patient group in predicting the development of new AF risk.
运动试验时过度的高血压反应与不良心血管事件相关，如左心室肥厚和心房颤动（AF）。在本研究中，我们探讨了运动试验时机电延迟与过度高血压反应之间的关系。
本研究纳入了25名运动应激试验时有高血压反应的患者以及28名年龄和性别与之相似、运动应激试验时血压反应正常的患者作为对照组。
研究组之间在动态血压值、传统超声心动图检查结果和运动应激试验结果方面无统计学差异。与对照组相比，运动应激试验高血压反应组的侧壁PA-TDI时间（组织多普勒成像测量的从P波开始到A'波开始的时间）、左心房机电延迟和房间机电延迟显著更长（分别为74.0±6.3 vs. 68.8±5.7，p=0.003；24.7±7.0 vs. 19.6±7.1，p=0.013；36.8±8.5 vs. 30.6±6.6，p=0.003）。
对该患者群体进行无创性早期机电延迟检测可能有助于预测新发房颤风险的发生。
