Background: Cardiac systolic dysfunction was potentially found in adult patients with end-stage renal disease (ESRD) who have preserved left ventricular ejection fraction (EF%). In children with ESRD, little data are available on early changes in myocardial function. This study aimed to detect the early changes in myocardial mechanics in pediatric patients with ESRD using speckle tracking echocardiography (STE). Methods: Thirty ESRD children receiving hemodialysis (HD) and30 age-matched controls were prospectively studied. Patients underwent echocardiographic studies before and after HD. Left ventricular longitudinal strain (LS), circumferential strain (CS), and radial strain (RS) myocardial deformation parameters (strain, strain rate) were evaluated by STE. Results: The LS was significantly reduced in pre-HD and post-HD patients compared with controls ( P = .000). Controls showed the highest global longitudinal strain. The RS measurements did not differ significantly among the studied groups except for the inferior segment that is significantly reduced after HD compared with controls ( P < .05). The CS was significantly reduced in pre-HD and post-HD patients compared with controls at the lateral and posterior segments ( P = .035 and P = .013, respectively). Conclusion: Speckle-tracking echocardiography might detect early changes in myocardial mechanics in children with ESRD with preserved EF%.

Aim: to assess the results of speckle tracking echocardiography (STE) in patients of working age with acute inferior wall myocardial infarction (MI) in the early period after coronary stenting. Patients and Methods: STE was performed using EPIQ-7 Ultrasound Machine (Philips, USA) in 55 patients with acute inferior wall MI one week after percutaneous coronary intervention and 29 healthy individuals of working age. Patients with acute inferior wall MI were divided into two subgroups, i.e., with (n=45) or without (n=10) areas of local contractile impairment (dyskinesia, akinesia, hypokinesia). Results: the most common cause of MI was the occlusion of the right coronary artery (82.4% in subgroup 1 and 60% in subgroup 2) in multivascular involvement (84.4% and 90%. respectively). In patients with local contractile impairment, reduced left ventricular ejection fraction (EF) was reported in 28.9%, global longitudinal strain in 86.7%, and global circular strain in 76.7%. Meanwhile, in patients without local contractile impairment, left ventricular ejection fraction (LV EF) was within normal ranges, global longitudinal strain was reported in 100% and global circumferential strain in 70%. The presence and severity of local dysfunction did not affect the reduction in segmental strain (median varied from -9% to -15%). In inferior wall MI, the abnormal regional longitudinal strain of 6 LV segments (basal and mid inferoseptal, inferior, and inferolateral) was reported in both hypokinesia and normokinesia. Conclusions: ultrasound evaluation of systolic LV function using STE is characterized by greater diagnostic value compared to the measurement of EF only and objectifies the efficacy of surgery. Quantitative assessment of the recovery of both global and local systolic contractility is another advantage of STE allowing for personalized treatment.

Lupus Myocarditis

Aims Lupus myocarditis occurs in 5–10% of patients with systemic lupus erythematosus (SLE). No single feature is diagnostic of lupus myocarditis. Speckle tracking echocardiography (STE) can detect subclinical left ventricular dysfunction in SLE patients, with limited research on its utility in clinical lupus myocarditis. We report on STE in comparison to conventional echocardiography in patients with clinical lupus myocarditis. Methods and results A retrospective study was done at a tertiary referral hospital in South Africa. SLE patients with lupus myocarditis were included and compared to healthy controls. Echocardiographic images were reanalyzed, including global longitudinal strain through STE. A poor echocardiographic outcome was defined as final left ventricular ejection fraction (LVEF) <40%. 28 SLE patients fulfilled the criteria. Global longitudinal strain correlated with global (LVEF: r = −0.808; P = 0.001) and regional (wall motion score: r = 0.715; P < 0.001) function. In patients presenting with a LVEF ≥50%, global longitudinal strain (P = 0.023), wall motion score (P = 0.005) and diastolic function (P = 0.004) were significantly impaired vs controls. Following treatment, LVEF (35–47% (P = 0.023)) and wall motion score (1.88–1.5 (P = 0.017)) improved but not global longitudinal strain. Initial LVEF (34%; P = 0.046) and global longitudinal strain (−9.5%; P = 0.095) were lower in patients with a final LVEF <40%. Conclusions This is the first known report on STE in a series of patients with clinical lupus myocarditis. Global longitudinal strain correlated with regional and global left ventricular function. Global longitudinal strain, wall motion score and diastolic parameters may be more sensitive markers of lupus myocarditis in patients presenting with a preserved LVEF ≥50%. A poor initial LVEF and global longitudinal strain were associated with a persistent LVEF <40%. Echocardiography is a non-invasive tool with diagnostic and prognostic value in lupus myocarditis.

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.

Abstract Introduction Left ventricular non-compaction (LVNC) is a relatively new cardiomyopathy, first reported by Chin et al. in 1990. Since then, much has been learned about this entity, but until now, there are some limitations for the diagnosis of this disease. Cardiac Magnetic Resonance Imaging is considered the gold standard for the diagnosis of LVNC, but echocardiography remains the first line imaging modality due to its availability and cost efficacy. Case report In this case, we report a case of an asymptomatic 21 years old young male with no personal or familiar history of cardiomyopathies. Two dimensional echocardiography (2D Echo) evidenced increased left ventricular trabeculation in the apical segments of lateral and anterior walls and a non compacted myocardium/ (compacted + non compacted myocardium) ratio of 0,33, compatible with LVNC according to Chin´s criteria. 3D Echo provided more detailed LV morphology analysis and 3D Echo Color Doppler evidenced ventricular flow within the intraventricular recesses. Strain analysis by speckle tracking (STE) evidenced global longitudinal strain = - 17% (Normal values &lt; -18%), probably related to an incipient systolic dysfunction not evidenced by the evaluation of left ventricular ejection fraction by 2D Echo. Conclusions This case illustrates new echocardiographic modalities for LVNC diagnosis. 3D Echo and STE are new technologies that may play an incremental role in the evaluation of LVNC but need further investigation and validation.

Background: Myocardial inflammation often complicates leptospirosis, a re-emerging global zoonosis. Leptospirosis associated myocardial dysfunction is equivocal and the pattern of cardiac involvement may not differ from that of sepsis associated myocarditis. Methods: We prospectively compared cardiac involvement in 113 intensive care unit patients with severe leptospirosis to 31 patients with sepsis syndrome using a comprehensive assessment comprising of clinical presentation, electrocardiography, two-dimensional echocardiography (with global longitudinal strain calculation), and cardiac biomarker evaluation. Binomial logistic regression was performed to identify independent predictors of left ventricular systolic dysfunction in leptospirosis. Results: Compared to sepsis syndrome, leptospirosis patients were younger, had higher body mass index measurements and were more likely to be smokers. Electrocardiography abnormalities were common and similar in both groups. Myocardial systolic dysfunction was common in both groups (leptospirosis: 55.86% vs sepsis syndrome: 51.61%, p=0.675) with subclinical left ventricular systolic dysfunction (characterized by abnormal global longitudinal strain and normal left ventricular ejection fraction) being most frequent followed by isolated right ventricular systolic dysfunction, isolated left ventricular systolic dysfunction, and bi-ventricular systolic dysfunction (leptospirosis: 31.43%, 18.42%, 13.16%, 10.53%, respectively; sepsis syndrome: 22.22%, 12.00%, 12.00%, 8.00%, respectively ( p>0.05 for each comparator)). Leptospirosis patients had a trend towards greater troponin-T elevation (61.0% vs 40.0%, p=0.057). ST-segment elevation and elevated troponin were independent predictors of reduced left ventricular ejection fraction in leptospirosis. Conclusions: Cardiac involvement in leptospirosis appears to be similar to that of sepsis syndrome, with myocardial systolic dysfunction being common. As such, clinical vigilance pertaining to cardiac status is paramount in these high-risk 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.
