2D Speckle Tracking

Background and objectives: Childhood obesity has reached epidemic levels in the world. Obesity in children is defined as a body mass index (BMI) equal to or above the 95th percentile for age and sex. The aim of this study was to determine early changes in cardiac structure and function in obese children by comparing them with their nonobese peers, using echocardiography methods. Materials and methods: The study enrolled 35 obese and 37 age-matched nonobese children. Standardized 2-dimensional (2D), pulsed wave tissue Doppler, and 2D speckle tracking echocardiography were performed. The z-score BMI and lipid metabolism were assessed in all children. Results: Obese children (aged 13.51 ± 2.15 years; 20 boys; BMI z-score of 0.88 ± 0.63) were characterized by enlarged ventricular and atrial volumes, a thicker left ventricular posterior wall, and increased left ventricular mass. Decreased LV and RV systolic and diastolic function was found in obese children. Atrial peak negative (contraction) strain (−2.05% ± 2.17% vs. −4.87% ± 2.97%, p < 0.001), LV and RV global longitudinal strain (−13.3% ± 2.88% vs. −16.87% ± 3.39%; −12.51% ± 10.09% vs. −21.51% ± 7.42%, p < 0.001), and LV global circumferential strain (−17.0 ± 2.7% vs. −19.5 ± 2.9%, p < 0.001) were reduced in obese children. LV torsion (17.94° ± 2.07° vs. 12.45° ± 3.94°, p < 0.001) and normalized torsion (2.49 ± 0.4°/cm vs. 1.86 ± 0.61°/cm, p = 0.001) were greater in obese than nonobese children. A significant inverse correlation was found between LV and RV global longitudinal strain and BMI (r = −0.526, p < 0.01; r = −0.434, p < 0.01) and total cholesterol (r = −0.417, p < 0.01). Multivariate analysis revealed that the BMI z-score was independently related to LV and RV global longitudinal strain as well as LV circumferential and radial strain. Conclusion: 2D speckle tracking echocardiography is beneficial in the early detection of regional LV systolic and diastolic dysfunctions, with preserved ejection fraction as well as additional RV and atrial involvement, in obese children. Obesity may negatively influence atrial and ventricular function, as measured by 2D speckle tracking echocardiography. Obese children, though they are apparently healthy, may have subclinical myocardial dysfunction.

Introduction: In light of previous studies reporting the significant effects of preeclampsia on cardiac dimensions, we sought to evaluate changes in the left ventricular (LV) systolic and diastolic functions in patients with preeclampsia with a view to investigating changes in cardiac strain. <br /> Methods: This cross-sectional study evaluated healthy pregnant women and pregnant women suffering from preeclampsia who were referred to our hospital for routine healthcare services. LV strain was measured by 2D speckle-tracking echocardiography. <br /> Results: Compared with the healthy group, echocardiography in the group with preeclampsia showed a significant increase in the LV end-diastolic diameter (47.43 ± 4.94 mm vs 44.84 ± 4.30 mm; P = 0.008), the LV end-systolic diameter (31.16 ± 33.3 mm vs 29.20 ± 3.75 mm; P = 0.008), and the right ventricular diameter (27.93 ± 1.71 mm vs 24.53 ± 23.3; P = 0.001). The mean global longitudinal strain was -18.69 ± 2.8 in the group with preeclampsia and -19.39 ± 3.49 in the healthy group, with the difference not constituting statistical significance (P = 0.164). The mean global circumferential strain in the groups with and without preeclampsia was -20.4 ± 12.4 and -22.68 ± 5.50, respectively, which was significantly lower in the preeclampsia group (P = 0.028).<br /> Conclusion: The development of preeclampsia was associated with an increase in the right and left ventricular diameters, as well as a decrease in the ventricular systolic function, demonstrated by a decline in global circumferential strain.

Two-dimensional speckle-tracking echocardiography (2D–STE) is an advanced echocardiographic technique based on deformation imaging that allows comprehensive evaluation of the myocardial function. Clinical application of 2D–STE holds great potential for its ability to provide valuable information on both global and regional myocardial function and to quantify cardiac rotation and synchronicity, which are not readily possible with the conventional echocardiography. It has gained growing importance over the past decade, especially in human medicine, and its application includes assessment of myocardial function, detection of subclinical myocardial dysfunction and serving as a prognostic indicator. This review illustrates the fundamental concepts of deformation analysis and gives an overview of the current understanding and its clinical application of this technique in veterinary medicine, with a focus on early detection of left ventricular (LV) dysfunction in dogs.

Abstract Funding Acknowledgements None Background Cigarette smoking effects myocardium with several mechanisms such as sympathetic nervous system activation, oxidative stress and endothelial dysfunction. Chronic smokers have an increased risk of morbidity and mortality associated with adverse cardiac events. Echocardiography is the well-established non-invasive diagnostic tool for the assessment of cardiac systolic and diastolic functions. 2D speckle tracking echocardiography (STE) has been widely used for this purpose in recent years. Purpose The aim of this study is to compare the left ventricle, left atrium and right ventricle systolic functions with 2D speckle tracking echocardiography in chronic smokers and non-smoker healthy population. Method 40 healthy participant (mean age 33.4 ± 10.0) without smoking history, 42 healthy participant (mean age 33.9 ± 9.2) who had smoking history at least 3 years without history of cardiac disease or any other chronic diseases such as hypertension, diabetes mellitus, kidney failure were prospectively included. In addition to Standard 2D echocardiographic measurements, left ventricular global longitidunal strain (LvGLS), right ventricular global longitidunal strain (RvGLS), left atrial strain and strain rate were analyzed with Vivid E9, offline using a customized software package. Results Smokers had lower peak early diastolic velocity (E) and E/A (late diastolic velocity) ratio in mitral inflow (0.70 ± 0.13 vs 0.77 ± 0.13, p = 0.023; 1.47 ± 0.44 vs 1.73 ± 0.44, p = 0.011; respectively). Peak early diastolic velocity of mitral valve medial annulus and E’/A’ ratio (0.11 ± 0.02 vs 0.12 ± 0.02, p = 0.023; 1.20 ± 0.37 vs 1.40 ± 0.46, p = 0.039; respectively) was lower in smokers. LvGLS and RvGLS were significantly impaired in smokers (-17.65 ± 3.01 vs -19.21 ± 2.52, p = 0.013; -18.96 ± 4.47 vs -21.06 ± 4.58, p = 0.039; respectively). Although εs, reservoir phase strain of left atrium; εe, conduit phase strain of left atrium; εa, contractile phase strain of left atrium were similar between two groups, εe/εa was significantly lower in smokers than non-smokers (1.32 ± 0.59, 1.63 ± 0.63, p = 0.026). Conclusion Impaired RV deformation was found in chronic cigarette smokers. Besides standardized diastolic dysfunction parameters εe/εa might be used for the early indicator of diastolic dysfunction. Although there was no statistically significant difference with left ventricular ejection fraction between smokers and non-smokers, LvGLS which is the early indicator of LV systolic dysfunction in chronic smokers might be used for the early assesment of LV systolic impairment.
