BACKGROUND AND PURPOSE
Electrocardiographic left ventricular hypertrophy (LVH) with strain pattern has been documented as a marker for LVH. Its presence on the ECG of hypertensive patients is associated with poor prognosis. The study was carried out to assess the association of the electrocardiographic strain with left ventricular mass (LVM) and function in hypertensive Nigerians.
MATERIAL AND METHODS
ECG as well as echocardiograms were performed in 64 hypertensive patients with ECG-LVH and strain pattern, 65 patients with ECG-LVH by Sokolow-Lyon (SL) voltage criteria and 62 normal controls.
RESULTS
The study showed that electrocardiographic left ventricular (LV) strain pattern is associated with dilated left atrium, larger LV internal dimensions and greater absolute and indexed LVM in hypertensive Nigerians compared with ECG-LVH by SL voltage criteria alone or normal controls.
CONCLUSION
The findings of this study support the fact that the ECG strain pattern is associated with increased LVM and an increased risk of developing abnormal LV geometry.
背景与目的
心电图左心室肥厚（LVH）伴应变模式已被证明是LVH的一个标志物。其在高血压患者心电图上的出现与预后不良相关。本研究旨在评估尼日利亚高血压患者心电图应变与左心室质量（LVM）及功能之间的关联。
材料与方法
对64例有心电图LVH及应变模式的高血压患者、65例根据索科洛 - 里昂（SL）电压标准诊断为心电图LVH的患者以及62例正常对照者进行了心电图和超声心动图检查。
结果
研究表明，与仅根据SL电压标准诊断为心电图LVH的患者或正常对照相比，尼日利亚高血压患者的心电图左心室（LV）应变模式与左心房扩大、左心室内径增大以及更大的绝对和指数化LVM相关。
结论
本研究结果支持以下事实，即心电图应变模式与LVM增加以及左心室几何形状异常风险增加相关。
