Basal Rotation

The aim of this study was to evaluate selected parameters of strain and rotation of the left ventricle (the basal rotation (BR) index, the basal circumferential strain (BCS) index, and the global longitudinal strain (GLS) of the left ventricle) in male athletes with physiological cardiac hypertrophy (LVH group), and athletes (non-LVH group) and non-athletes without hypertrophy (control group, CG). They were evaluated using transthoracic echocardiography and speckle tracking echocardiography before and after an incremental exercise test. The LVH group demonstrated lower BR at rest than the non-LVH group (p < 0.05) and the CG (p < 0.05). Physical effort had no effect on BR, nor was this effect different between groups (p > 0.05). There was a combined influence of LVH and physical effort on BR (F = 5.70; p < 0.05) and BCS (F = 4.97; p < 0.05), but no significant differences in BCS and GLS at rest between the groups. A higher BCS and lower GLS after exercise in the LVH group were demonstrated in comparison with the CG (p < 0.05). Left ventricular basal rotation as well as longitudinal and circumferential strains showed less of a difference between rest and after physical effort in subjects with significant myocardial hypertrophy. In conclusion, the obtained results may suggest that echocardiographic assessment of basal rotation and circumferential strain of the left ventricular can be important in predicting cardiac disorders caused by physical effort in individuals with physiological and pathological heart hypertrophy.

Functional Changes

By using two-dimensional speckle tracking echocardiography, we aimed to investigate the structural and functional changes on myocardium in chronic asymptomatic alcoholics without any cardiovascular disease. Forty-one consecutive asymptomatic male alcoholics who were admitted to the outpatient alcoholism unit and 30 age matched healthy male volunteers selected as the control group were enrolled in the study. The study group were investigated by using standard two-dimensional echocardiography and speckle tracking echocardiography. The left ventricular (LV) global longitudinal strain and LV global circumferential strain were significantly lower in alcoholics when compared with control subjects. There was no difference in global radial strain between the two groups. To demonstrate the effect of total life time dose of ethanol (TLDE) on echocardiographic abnormalities, we assessed the correlation analysis. There was a nonsignificant weak correlation between global LV circumferential strain and TLDE (r=0.27,p=0.083). Speckle tracking echocardiography derived left ventricular systolic function was impaired in chronic alcoholic patients when compared with healthy controls.

AbstractThe aim of this study was to determine the left ventricular myocardial deformation and segmental myocardial dysfunction by speckle tracking echocardiography and tissue Doppler imaging among the operated patients with anomalous origin of the left coronary artery from the pulmonary artery. The study was conducted on 12 patients diagnosed with anomalous origin of the left coronary artery from the pulmonary artery, who had been operated upon between 2001 and 2013 at the medical centres of Shiraz University of Medical Sciences, Shiraz, Iran. The mean age of the patients at the time of surgical correction was 12.6 years ranging from 6 months to 43 years, and the duration of postoperative follow-up was between 1 and 12 years. Comparison of the strain rate between the patients with acceptable ejection fraction and the control group by tissue Doppler imaging showed significant differences between the two groups regarding the lateral wall (p<0.001), but not the septal wall of the left ventricle (p=0.65). Moreover, the strain values by the speckle tracking method revealed significant differences between the patient and the control group regarding the global strain (p=0.016) and anterior, lateral, and posterior segments of the left ventricle. Although postoperative conventional echocardiography revealed normal global left ventricular function with acceptable ejection fraction, abnormal myocardial deformation of the variable segments of the left ventricle with regional and global myocardial dysfunction were well defined by speckle tracking echocardiography.

Objective: Recent studies have showed that Tissue Doppler Imaging and Speckle Tracking Echocardiography can discover these changes at functional and structural cardiac in athletes at early stage, especially at the footballers. The purpose of this research was evaluated the structural and functional adaption of left ventricular in footballer by conventional and advanced echocardiography. Materials and methods: We performed a cross-sectional study of 30 footballers who have been trained over 2 years compared to 30 healthy candidate with the same ages. We carried out TM, 2D, STE. Echo machine was Philips Affinity 50CV with QLAB version 10.04 which can analyze online or offline. Result: In comparison with control group, IVSd, LVEDd, PWTd, LVM, LVMI (p = 0.001) was different from athlete group. Left ventricular adaption trended to eccentric hypertrophy and increased left ventricular mass index. A wave was decrease velocity and increased E/A, E/El’, E/E’s ratio. Base circumferential strain, apex circumferential strain, rotation and twist (10.12 ± 1.2) (°) athletes (7.42 ± 2.6) (°) control group with (p = 0.05), were more than control group. Conclusion: Conventional and advanced echocardiography can evaluate structural and functional left ventricular adaption in athletes. Especially, STE provided more data in myocardial deformation, rotation and twist so that it can discover these changes at athlete heart in early stages Key words: Athletes heart, Speckle Tracking Echocardiography, Tissue Doppler Imaging

Takotsubo Syndrome

Abstract Funding Acknowledgements Type of funding sources: None. Main funding source(s): North-Western State Medical University named after I.I. Mechnikov Complete improvement of left ventricle systolic function is an essential feature of takotsubo syndrome (TTS). Speckle -tracking echocardiography (STE) provides quantitative information about myocardial deformation, more accurately than conventional echocardiography. Objective to assess the global longitudinal strain (GLS) and global circumferential strain (GCS) by speckle-tracking echocardiography in patients with TTS in the long-term period. Materials and methods 14 female with TTS were monitored, average age 57.5 ± 28.5. The diagnosis was verified by ventriculography and echocardiography. 1 year after the attack, complaints of the patients, cardiovascular events (CE) and signs of heart failure were evaluated. All patients underwent echocardiography using a Vivid-4 (General Electric) with a Speckle-tracking function. The ejection fraction (EF) of the left ventricle (LV), the zone of disorders  of local contractility, the level of GLS and GCS were evaluated. Results after an 1 year of observation, all patients had a good clinical condition, there were no CE, and heart failure was absent. The EF level was 56.3 ± 3.45%; no zones of disorders of local contractility were found in any patient. A GLS level below normal was observed in 7 patients (-12.05% ± 5.15%), and was normal in 7 patients (less than -18%), GCS level was reduced in 3 (21.4%) patients (- 9.7 ± 3.4%) at a normal level of -18 and below. Conclusions despite the absence of global and local contractility disorders in echocardiography, GLS was revealed in 50% of patients, GCS in 20% of patients. Thus, speckle-tracking shows that in some patients changes in LV contractility persist in the long term. It can be explained by a change in the orientation of the myocardial fibers due to remodeling, but this requires further evaluation.

Clinical Benefits

Abstract Background: Sodium-glucose cotransporter 2 inhibitors (SGLT2i) lower cardiovascular events in type 2 diabetes mellitus (T2DM) patients, although the mechanisms underlying these benefits are not clearly understood. Our aim was to study the effects of SGLT2i on left ventricular remodelling and longitudinal strain.Methods: Between November 2019 and April 2020, we included 52 patients with T2DM ≥18 years old, with HbA1c between 6.5% and 10.0%, and estimated glomerular filtration ≥45 ml/min/1.73 m2. Patients were classified into SGLT2i group and control group, according to prescribed treatment by their referring physician. Conventional and speckle tracking echocardiography were performed by blinded sonographers, at baseline and after 6 months of treatment.Results: Among the 52 included patients (44% females, mean age 66.8±8.6 years, mean HbA1c was 7.40±0.7%), 30 patients were prescribed SGLT2i and 22 patients were classified as control group. Mean change in indexed left ventricular mass (LVM) was -10.85±3.31 g/m2 (p=0.003) in the SGLT2i group, and +2.34±4.13 g/m2 (p=0.58) in the control group. Absolute value of Global Longitudinal Strain (GLS) increased by a mean of 1.29±0.47 (p=0.011) in the SGLT2i group, and 0.40±0.62 (p=0.34) in the control group. We did not find correlations between changes in LVM and GLS, and other variables like change in HbA1c.Conclusions: Among patients with T2DM, SGLT2i were associated with a significant reduction in indexed LVM and a significant increment in longitudinal strain measured by speckle tracking echocardiography, which may explain in part the clinical benefits found in clinical trials.

Abstract Introduction Hypereosinophilic syndrome (HES) is a very heterogeneous group of disorders with varied etiologies characterized by peripheral eosinophilia and eosinophilic tissue/end-organ damage. In the present study, the ability of a novel non-invasive clinical tool, three-dimensional speckle-tracking echocardiography (3DSTE) was investigated to reveal any change in left ventricular (LV) rotational mechanics in clinically asymptomatic HES patients without manifest organ damage as determined by conventional diagnostic methods. Methods The present study comprised 13 patients established diagnosis of HES. However, one patient with idiopathic HES has been excluded due to insufficient image quality. The remaining patient population contained 11 cases with idiopathic HES and one patient with acute T-lymphoma associated HES (mean age: 59.7 ± 13.7 years, 8 males). The control group consisted of 36 healthy volunteers (mean age: 52.9 ± 8.3 years, 23 males). All HES patients and controls underwent complete two-dimensional Doppler echocardiography and 3DSTE. Results Both LV apical rotation (4.86 ± 1.92 degree vs. 10.07 ± 3.92 degree, p &lt; 0.0001) and LV twist (8.52 ± 2.79 degree vs. 14.41 ± 4.26 degree, p &lt; 0.0001) showed significant deteriotations in most of HES patients. In 2 subjects absence of LV twist called as LV „rigid body rotation’ (RBR) was detected. One patient had 1.77 degree counterclockwise (abnormally directed) LV basal rotation and 14.29 degree counterclockwise (normally directed) LV apical rotation resulting in 12.59 degree LV apico-basal gradient. The other patient had normally directed -2.09 degree LV basal rotation and almost zero (-0.27 degree) LV apical rotation resulting in 1.82 degree LV apico-basal gradient. Conclusions Reduced LV apical rotation and twist could be demonstrated in HES. LV-RBR could be detected in some HES patients.

Background Early detection of subclinical left ventricular (LV) systolic dysfunction in hypertensive patients is important for the prevention of progression of hypertensive heart disease. Methods We studied 60 hypertensive patients (age ranged from 21 to 49 years, the duration of hypertension ranged from 1 to 18 years) and 30 healthy controls, all had preserved left ventricular ejection fraction (LVEF), detected by two-dimensional speckle tracking echocardiography (2D-STE). Results There was no significant difference between the two groups regarding ejection fraction (EF) by Simpson's method. Systolic velocity was significantly higher in the control group, and global longitudinal strain was significantly higher in the control group compared with the hypertensive group. In the hypertensive group, 23 of 60 patients had less negative global longitudinal strain than −19.1, defined as reduced systolic function, which is detected by 2D-STE (subclinical systolic dysfunction), when compared with 3 of 30 control subjects. Conclusion 2D-STE detected substantial impairment of LV systolic function in hypertensive patients with preserved LVEF, which identifies higher risk subgroups for earlier medical intervention.

Abstract Background To investigate the value of two-dimensional speckle tracking echocardiography (2D-STE) in evaluating cardiac functions in type 2 diabetes mellitus (T2DM) with hyperlipidemia. Methods Sixty T2DM patients with normal left ventricular ejection fraction (LVEF) and poorly-controlled blood glucose were selected. Among these, thirty had hyperlipidemia. Thirty age- and gender-matched healthy individuals were recruited as the normal control group. Longitudinal strain of left ventricular segments, left ventricular global longitudinal strain (LV GLS), left atrial global longitudinal strain (LA GLS), right ventricular global longitudinal strain (RV GLS) and right atrial global longitudinal strain (RA GLS) were measured by 2D-STE. Results (1) Compared with the normal control group, LV GLS in T2DM group and T2DM with hyperlipidemia group decreased (P < 0.05), but there was no significant difference of LV GLS between T2DM group and T2DM with hyperlipidemia group (P > 0.05). Compared with the normal control group and T2DM group, longitudinal strain of middle segment of LV in T2DM with hyperlipidemia group decreased (P < 0.05). (2) There was a significant difference in LA GLS among the three groups. LA GLS of T2DM with hyperlipidemia group was lower compared with the normal control and T2DM group (P < 0.05). (3) Compared with the normal control group, RV GLS in T2DM group and T2DM with hyperlipidemia group was lower (P < 0.05), but there was no significant difference of RV GLS between T2DM group and T2DM with hyperlipidemia group (P > 0.05). RA GLS in T2DM with hyperlipidemia group decreased (P < 0.05) compared to the normal control group and T2DM group. Conclusion Speckle tracking echocardiography can effectively evaluate cardiac dysfunction in patients with T2DM. LA GLS and RA GLS can be used as potential markers of cardiac dysfunction in T2DM with hyperlipidemia, and provide the basis for early clinical diagnosis and treatment.

Introduction. Left ventricular dysfunction is quite common in septic shock. Speckle-tracking echocardiography (STE) is a novel, highly sensitive method for assessing left ventricular function, capable of detecting subclinical myocardial dysfunction, which is not identified with conventional echocardiography. We sought to evaluate subclinical left ventricular systolic function in patients with septic shock using speckle-tracking echocardiography. Methods. From May 2017 to December 2018, patients aged ≥18 years admitted to the intensive care unit with the diagnosis of sepsis and septic shock based on the sepsis-3 definition were included. Patients with other causes of cardiac dysfunction were excluded. Transthoracic echocardiography was performed for all the patients within 24 hours of diagnosis. Left ventricular systolic function was assessed using conventional echocardiography and speckle-tracking echocardiography. Results. Patients with septic shock (n = 90) (study group) and 37 matched patients with sepsis but no septic shock (control group) were included. Left ventricular ejection fraction (LVEF) by conventional echocardiography showed no significant difference between two groups (58.2 ± 9.9 vs. 58.6 ± 8.3, p=0.804). The global longitudinal strain (GLS) by STE was significantly reduced in patients with septic shock compared with that in the control (−14.6 ± 3.3 vs. −17.1 ± 3.3, p<0.001). Based on the cutoff value of GLS ≥ −15% for the definition of subclinical left ventricular systolic dysfunction, this dysfunction was detected in 50 patients with septic shock (55.6%) and in 6 patients in the control group (16.2%) (p<0.05). Conclusions. Speckle-tracking echocardiography can detect early subclinical left ventricular systolic dysfunction via the left ventricular global longitudinal strain compared with conventional echocardiographic parameters in patients with septic shock.
