Background and Objectives: Patients with chronic kidney disease (CKD) exhibit a highly increased risk of cardiovascular (CV) morbidity and mortality. Subtle changes in left ventricular function can be detected by two-dimensional (2D) speckle tracking echocardiography (STE). This study investigated whether myocardial dysfunction detected by 2D STE may aid in CV and all-cause mortality risk assessment in patients with CKD stages 3 and 4. Method: A study group of 285 patients (CKD 3: 193 patients; CKD 4: 92 patients) and a healthy control group (34 participants) were included in the retrospective study. 2D STE values as well as early and late diastolic strain rates were measured in ventricular longitudinal, circumferential and radial directions. Patients’ CV and all-cause outcome was determined. Results: In the CKD group all measured longitudinal STE values and radial strain were significantly reduced compared to the control group. Cox proportional hazards regression revealed global longitudinal strain to predict CV and all-cause mortality (hazard ratio [HR] 1.15, 95% CI 1.06–1.25; p = 0.0008 and HR 1.09, 95% CI 1.04–1.14; p = 0.0003). After adjustment for sex, age, diabetes, estimated glomerular filtration rate, and preexisting CV disease, this association was maintained for CV mortality and all-cause mortality (HR 1.16, 95% CI 1.06–1.27; p = 0.0019 and HR 1.08, 95% CI 1.03–1.14; p = 0.0026, respectively). Conclusions: The present study shows that 2D STE detects reduced left ventricular myocardial function and allows the prediction of CV and all-cause mortality in patients at CKD stages 3 and 4.

AbstractIntroductionThe aim of this study is to determine early changes in cardiac function of children with chronic kidney disease by using 2D-speckle tracking echocardiography.MethodThe study included 38 children – 16 girls and 22 boys – diagnosed as having chronic kidney disease in the nephrology department with a glomerular filtration rate of <90 ml/minute/1.73 m2 for at least 3 months. A total of 37 – 15 girls and 22 boys – age- and sex-matched healthy children were included as the control group. 2D-Speckle tracking echocardiography was performed in all subjects.ResultsThe mean age was 13.45±2.8 years in patients and 12.89±3.07 years in controls. Systolic and diastolic blood pressures and left ventricular mass index were significantly higher in patients (p<0.05). The values of mitral e, mitral a, mitral e/a ratio, and mitral deceleration time were not different between the groups. Tricuspid annular plane systolic excursion values were lower in patients (p<0.01). Global strain values in apical long-axis 3-chamber and 2-chamber views were significantly lower in patients (p<0.05). Longitudinal, radial, and circumferential peak systolic strain values were lower in patients, but the difference was statistically significant in all segments of longitudinal view and basal segment of circumferential view (p<0.05). Radial and circumferential systolic strain rates were significantly lower in patients in all three segments (p<0.05). Moreover, early diastolic strain rate was significantly lower in longitudinal and radial apical segments and in all segments of circumferential measurements in patients. Besides, strain rate e/a ratio was significantly lower in all longitudinal segments of patients (p=0.01).ConclusionThe study concluded that 2D-speckle tracking echocardiography method can determine cardiac involvement earlier than conventional echocardiography in children with chronic kidney disease having preserved ejection fraction.

Abstract Background Cardiovascular disease is an important driver of the increased mortality associated with chronic kidney disease (CKD). Higher left ventricular mass (LVM) predicts increased risk of adverse cardiovascular outcomes and total mortality, but previous reviews have shown no clear association between intervention-induced LVM change and all-cause or cardiovascular mortality in CKD. Methods The primary objective of this meta-analysis was to investigate whether treatment-induced reductions in LVM over periods ≥ 12 months were associated with all-cause mortality in patients with CKD. Cardiovascular mortality was investigated as a secondary outcome. Measures of association in the form of relative risks (RRs) with associated variability and precision (95% confidence intervals [CIs]) were extracted directly from each study, when reported, or were calculated based on the published data, if possible, and pooled RR estimates were determined. Results The meta-analysis included 38 trials with duration ≥ 12 months: 6 of erythropoietin stimulating agents treating to higher vs. lower hemoglobin targets, 10 of renin-angiotensin-aldosterone system inhibitors vs. placebo or another blood pressure lowering agent, 14 of modified hemodialysis regimens, and 8 of other types of interventions. All-cause mortality was reported in 116/2385 (4.86%) subjects in intervention groups and 161/2404 (6.70%) subjects in control groups. The pooled RR estimate of the 24 trials ≥ 12 months with ≥ 1 event in ≥ 1 group was 0.72 (95% CI 0.57 to 0.91, p = 0.005), with little heterogeneity across studies. Directionalities of the associations in intervention subgroups were the same. Sensitivity analyses of ≥ 6 months (31 trials), ≥ 9 months (26 trials), and > 12 months (9 trials), and including studies with no events in either group, demonstrated similar risk reductions to the primary analysis. The point estimate for cardiovascular mortality was similar to all-cause mortality, but not statistically significant: RR 0.66, 95% CI 0.38 to 1.15. Conclusions These results suggest that LVM regression may be a useful surrogate marker for benefits of interventions intended to reduce mortality risk in patients with CKD.

Abstract Background and aim: Chronic kidney disease may lead to left ventricular dysfunction. Early detection of cardiovascular disease in children with chronic kidney disease is essential to prevent cardiovascular morbidity and mortality in early adulthood. This study aimed to document the dysfunction using methods such as two-dimensional speckle-tracking echocardiography in the early stage. Methods: A total of 34 patients diagnosed with chronic kidney disease (mean age ± standard deviation, 10.5 ± 4.1 years) and 37 sex- and age-matched (mean age 9.8 ± 4.2 years) healthy controls were studied. The results of the two groups were compared along with those of the published studies. Results: The echocardiography measurements had no significant difference in the end-diastolic and end-systolic diameter values of left ventricular, ejection fraction, shortening fraction, mitral E value, mitral A value, and E/A ratio between the groups. Pulmonary artery systolic and diastolic pressure and left ventricular mass index were significantly higher in the patient group (p < 0.01). The longitudinal global strain values in the apical four-chamber, three-chamber, and two-chamber views and the total global strain values were significantly lower in the patients (p < 0.01). The circumferential global strain values in the apical, mid, basal, and total global strain were lower in the patient group, but this difference was statistically significant in the apical global and total global strain values (p < 0.05). Conclusions: Speckle-tracking echocardiography might help identify subclinical left ventricular dysfunction in patients with chronic kidney disease with unremarkable conventional echocardiography.

Abstract Coronavirus disease-19 (COVID-19) has been associated with subclinical myocardial dysfunction during its acute phase and a recurring pattern of reduced basal left ventricular longitudinal strain on speckle-tracking echocardiography (STE) in hospitalized patients. But a question still remains unanswered: speckle tracking echocardiography might also be suitable to detect residual myocardial involvement after acute stage of COVID-19? Methods and results: We studied 100 patients recovered from COVID-19 with STE to evaluate global (GLS) and segmentar longitudinal strain (LS) and compared with a control group of 100 healthy individuals. STE was performed at a median of 130.35 +/- 76.06 days after COVID-19 diagnostic. Demographic and echocardiographic parameters are similar in both groups. Left ventricular ejection faction (LVEF) and GLS were normal in COVID-19 patients (66.20 +/- 1.98% and -19.51 +/- 2.87%, respectively). A reduction in mean LS for the basal segments was found in COVID-19 (16.48 +/- 5.41%) when compared to control group (19.09 +/- 4.31%) (p<0.001). Conclusion: The present study suggests that COVID-19 induced cardiac involvement could persist after recovery of the disease and may be detected by deformation abnormalities using STE. COVID-19 induced myocardial involvement often shows specific LV deformation patterns due to pronounced edema and/or myocardial damage in basal LV segments.

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.

To investigate the association of body weight variability (BWV) with adverse cardiovascular (CV) outcomes in patient with pre-dialysis chronic kidney disease (CKD), a total of 1867 participants with pre-dialysis CKD from Korean Cohort Study for Outcomes in Patients With Chronic Kidney Disease (KNOW-CKD) were analyzed. BWV was defined as the average absolute difference between successive values. The primary outcome was a composite of non-fatal CV events and all-cause mortality. Secondary outcomes were fatal and non-fatal CV events and all-cause mortality. High BWV was associated with increased risk of the composite outcome (adjusted hazard ratio (HR) 1.745, 95% confidence interval (CI) 1.065 to 2.847) as well as fatal and non-fatal CV events (adjusted HR 1.845, 95% CI 1.136 to 2.996) and all-cause mortality (adjusted HR 1.861, 95% CI 1.101 to 3.145). High BWV was associated with increased risk of fatal and non-fatal CV events, even in subjects without significant body weight gain or loss during follow-up periods (adjusted HR 2.755, 95% CI 1.114 to 6.813). In conclusion, high BWV is associated with adverse CV outcomes in patients with pre-dialysis CKD.

Abstract Background: Acute cellular rejection (ACR) is a major complication after heart transplantation. Endomyocardial biopsy (EMB) remains the gold standard for its diagnosis, but it has concerning complications. We evaluated the usefulness of speckle tracking echocardiography (STE) and biomarkers for detecting ACR after heart transplantation.Methods: We prospectively studied 60 transplant patients with normal left and right ventricular systolic function who underwent EMB for surveillance six months after transplantation. Sixty age- and sex-matched healthy individuals constituted the control group. Conventional echocardiographic parameters, left ventricular global longitudinal, radial and circumferential strain (LV-GLS, LV-GRS and LV-GCS, respectively), left ventricular systolic twist (LV-twist) and right ventricular free wall longitudinal strain (RV-FWLS) were analyzed just before the procedure. We also measured biomarkers at the same moment. Results: Among the included 60 patients, 17 (28%) had severe ACR (grade ≥ 2R), and 43 (72%) had no significant ACR (grade 0 – 1R). The absolute values of LV-GLS, LV-twist and RV-FWLS were lower in transplant patients with ACR degree ≥ 2 R than in those without ACR (12.5% ± 2.9% vs 14.8% ± 2.3%, p=0.002; 13.9° ± 4.8° vs 17.1° ± 3.2°, p=0.048; 21.4%± 3.2% vs 16.6% ± 2.9%, p<0.001; respectively), while no differences were observed between the LV-GRS or LV-GCS. All of these parameters were lower in the transplant group without ACR than in the nontransplant control group, except for the LV-twist. Cardiac troponin I levels were significantly higher in patients with significant ACR than in patients without significant ACR [0.19 ng/mL (0.09–1.31) vs. 0.05 ng/mL (0.01–0.18), p=0.007]. The combination of troponin with LV-GLS, RV FWLS and LV-Twist had an AUC (area under curve) for the detection of ACR of 0.80 (0.68 – 0.92), 0.89 (0.81 – 0.93) and 0.79 (0.66 – 0.92), respectively. Conclusion: Heart transplant patients have altered left ventricular dynamics compared with control individuals. The combination of troponin with strain parameters had higher accuracy for the detection of ACR than the isolated variables and this association might select patients with a higher risk for ACR who will benefit from an EMB procedure in the first year after heart transplantation.
