ABSTRACT
BACKGROUND AND AIM:
This study aims to examine the relationship between the QRS-T angle (QRS-Ta) detected on electrocardiography and left ventricular global longitudinal strain (LV-GLS) calculated on echocardiography in prehypertensive patients. MATERIALS ANDMETHODS:
A total of 300 patients were included in our study, and the median value of QRS-Ta of the entire population was 27.The patients were divided into two groups (supramedian 148 patients, inframedian 152 patients) according to the median value. Statistical analysis was performed between the two groups.RESULTS:
LV-GLS was lower in the supramedian QRS-Ta group [20 (16-26) vs. 21 (16-27); p < 0.001]. A statistical difference was found between the two groups in age (p < 0.001), BMI (p < 0.001), Hs-troponin I (p < 0.001), aortic velocity (p = 0.023) and TAPSE (p = 0.005) parameters except for LV-GLS.The correlation between QRS-Ta and LV-GLS was determined by Spearman's correlation test (p < 0.001).In the multivariable logistic regression analysis model, LV-GLS (OR 0.365, 95%CI 0.171-0.780, p = 0.009) was one of the independent predictors for increased QRS-Ta. Others were determined as age (p < 0.001) and TAPSE (p = 0.015).CONCLUSIONS:
In this study, a strong relationship was found between QRS-Ta, which is easily calculated by ECG, and LV-GLS, which is an advanced echocardiographic examination, in prehypertensive patients.Palabras clave
