Multidirectional Global Left Ventricular Systolic Function in Normal Subjects and Patients with Hypertension: Multicenter Evaluation

Effect of Coronary Slow Flow on the Longitudinal Left Ventricular Function Assessed by 2‐Dimensional Speckle‐Tracking Echocardiography

“…Although that study was larger than our study, and frequency matching regarding hypertension and diabetes mellitus was done, we performed one‐to‐one patient matching for age, sex, hypertension, and diabetes mellitus. This factor is also applicable to a study conducted by Barutçu et al, 24 who showed that diabetes and hypertension could impair LV systolic and diastolic deformation 25 – 30 . As a result, the strength of our study compared with that study was the one‐to‐one matching of the patient and control groups regarding hypertension and diabetes mellitus.…”

Left ventricular layer function in hypertension assessed by myocardial strain rate using novel one-beat real-time three-dimensional speckle tracking echocardiography with high volume rates

“…This indicates that myocardial SR is more sensitive than LV EF and seems to be suitable to detect early stages of LV dysfunction. 27 Furthermore, Morris et al 28 and Ohara et al 29 reported using systolic LV strain assessed by 2D-STE that there was subtle LV systolic dysfunction in patients with HTN, even though LV EF was normal. We obtained a similar finding, as there was no difference in LV EF among the five groups, whereas not only LV strain in longitudinal and radial directions but also SR during systole in three directions assessed by novel 3D-STE even in hypertensive patients with concentric remodeling was already reduced.…”

Left atrial function: Correlation with left ventricular function and contractile reserve in patients with hypertension

“…Compared to tissue Doppler‐based technique, STE is angle‐independent and has better signal‐to‐noise ratio. The use of this noninvasive imaging technology in LV assessment has provided us with the capacity to detect subtle and subclinical LV functional impairment, when traditional echocardiographic parameters like LVEF remain within the “normal” range . In recent years, the use of this technology has been extended to assess LA function, and several studies have shown that the use of STE provides feasible and reproducible assessment of LA function .…”

[32][33][34] Abnormalities in LA strain as assessed by STE have been shown in various pathological conditions, including atrial fibrillation, 35 LV hypertrophy, 36 Our study results are in accordance with results from some other more recent studies.…”
