Abstract Introduction Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is increasingly utilized in young patients. Allo-HSCT usually requires myeloablative therapy that is potentially cardiotoxic. In addition, allo-HSCT survivors have a high prevalence of cardiovascular risk factors. Purpose We aim to describe left ventricular systolic function in long term survivors after allo-HSCT. Methods This study included 104 patients, aged (mean±SD) 18±10 years at allo-HSCT, and follow-up time was 17±6 years. 74% were sufferers of malignant disease. Pre-transplantation therapies consisted of anthracyclines (AnT) in 44% and mediastinal radiotherapy in 2%. Conditioning regimes consisted of cyclophosphamide with bulsulfsan in 77%. 22% received anti-lymphocyte globulin and 6% received total body irradiation. Left ventricular (LV) function was evaluated by 2D and 3D echocardiography. Healthy controls matched for age, sex and BMI were used in group comparisons. Group comparisons were performed by t-tests and chi-square. A linear regression was used to identify contributing factors to reduced systolic LV function in allo-HSCT survivors. Results Most parameters of LV systolic function including 2D and 3D LV ejection fraction (LVEF), global longitudinal strain (GLS), mitral annulus excursion (MAPSE) and s' were all significantly impaired after allo-HSCT as compared to the control group. Significant (p<0.05) contributors to LVEF in the multivariate regression analysis were age, AnT dosage, graft versus host disease (GVHD, occurring in 67%) and hypertension (HT, occurring in 31%). Allo-HSCT Control p value n 104 55 – Gender (female) 56 (54) 29 (53) 0.89 Age (yr) 35±12 36±11 0.44 BMI (kg/m2) 25±5 24±3 0.57 Fractional Shortening (%) 31±6 32±4 0.26 2D LVEF (%) 55±6 59±3 <0.005 3D LVEF (%) 54±5 58±3 <0.005 MAPSE (mm) 13±2 15±2 <0.005 Mean s' (mm) 81±17 89±17 <0.005 2D GLS (%) −17±2 −20±2 <0.005 Values: mean ± SD or n (%), t-test or chi-square. Conclusion LV systolic function is reduced in long term survivors of allo-HSCT. Pre-transplantation AnT, HT and GVHD are significantly associated with increased risk of cardiotoxicity.

AbstractPurpose: Cardiac resynchronisation therapy (CRT) improves left ventricular (LV) function acutely, with further improvements and reverse remodelling during chronic CRT. The current study investigated the relation between acute improvement of LV systolic function, acute mechanical recoordination, and long-term reverse remodelling after CRT. Methods: In 35 patients, LV speckle tracking longitudinal strain, LV volumes & ejection fraction (LVEF) were assessed by echocardiography before, acutely within three days, and 6 months after CRT. A subgroup of 25 patients underwent invasive assessment of the maximal rate of LV pressure rise (dP/dtmax,) during CRT-implantation. The acute change in dP/dtmax, LVEF, systolic discoordination (internal stretch fraction [ISF] and LV systolic rebound stretch [SRSlv]) and systolic dyssynchrony (standard deviation of peak strain times [2DS-SD18]) was studied, and their association with long-term reverse remodelling were determined. Results: CRT induced acute and ongoing recoordination (ISF from 45 ± 18 to 27 ± 11 and 23 ± 12%, p < 0.001; SRS from 2.27 ± 1.33 to 0.74 ± 0.50 and 0.71 ± 0.43%, p < 0.001) and improved LV function (dP/dtmax 668 ± 185 vs. 817 ± 198 mmHg/s, p < 0.001; stroke volume 46 ± 15 vs. 54 ± 20 and 52 ± 16 ml; LVEF 19 ± 7 vs. 23 ± 8 and 27 ± 10%, p < 0.001). Acute recoordination related to reverse remodelling (r = 0.601 and r = 0.765 for ISF & SRSlv, respectively, p < 0.001). Acute functional improvements of LV systolic function however, neither related to reverse remodelling nor to the extent of acute recoordination. Conclusion: Long-term reverse remodelling after CRT is likely determined by (acute) recoordination rather than by acute hemodynamic improvements. Discoordination may therefore be a more important CRT-substrate that can be assessed and, acutely restored.

Background: The number of coronary chronic total occlusion (CTO) patients with left ventricular (LV) systolic dysfunction is significant, but the clinical outcomes of these patients are rarely reported. The present retrospective cohort study aimed to investigate the long-term outcomes of successful recanalization vs. optimal medical therapy (MT) for CTOs in patients with preserved and impaired LV systolic function.Methods: A total of 1,895 patients with CTOs were stratified according to LV function. Of these, 1,420 patients (74.9%) with LV ejection fraction (LVEF) &gt;45% and 475 patients (25.1%) with LVEF ≤45% were treated with optimal MT or successful CTO percutaneous coronary intervention (PCI). A 1:1 propensity score matching (PSM) was conducted to reduce the impact of potential confounding on the outcomes. The primary outcome was the frequency of major adverse cardiac events (MACEs).Results: Throughout a 2.6-year follow-up and after adjusting for confounders, among patients with preserved LV function, successful CTO PCI was associated with reduced incidence of MACE (14.2 vs. 23.9%, adjusted HR 0.63, 95% CI 0.48–0.83, p = 0.001) compared to MT. There was no significant difference in MACE occurrence (29.6 vs. 28.9%, adjusted HR 1.05, 95% CI: 0.71–1.56, p = 0.792) between successful recanalization and MT in patients with LV systolic dysfunction. The primary outcome among patients with impaired and preserved LV systolic function after PSM was similar to that from earlier findings before PSM was conducted. A significant interaction between LV function and therapeutic strategy for MACE was observed (interaction p = 0.038).Conclusions: Compared to MT alone for management of patients with CTOs, successful CTO PCI may reduce the risk of MACE in patients with preserved LV systolic function, but not in patients with LV dysfunction.

Background Chronic severe anemia is a connnon disease. Cardiac output may increase when the hemoglobin (Hb) level decreases to < 7 g/dL for 3 months or more. Alteration of left ventricular (LV) function occurs frequently in children 'With chronic severe anemia, in the {onn of concentric LV hypertrophy, LV dilatation with or v.ithout LV hypertrophy, or systolic dysfunction. Objective To examine the correlation between Hb level and alteration of LV systolic function in children with chronic severe anemia. Methods We conducted a cross-sectional study in Adam Malik Hospital from October to December 2009. Subjects were chronic severely anemic children. Left ventricular systolic function (ejection fraction/EF, fractional shortening/FS) and dimensions (left ventricular end diastolic diameter/LVEDD and left ventricular end systolic diameter/LVESD) were measured using Hitachi EUB 5500 echocardiography unit. Univariate analysis  and Pearson correlation were performed.Results Thirty children were enrolled in the study. The mean of age was 113.5 months (SD 53.24). Hb values ranged from 2.1 to 6.9 g/dL with mean value of 4.6 g/dL (SD 1.44). Mean duration of anemia was 3.9 months (SD 0.70). Chronic severe anemia was not associated \\lith decreased LV systolic function [EF 62.2% (SD 9.16), r =0.296, P=0.112; FS 33.8% (SD 7.26), r =0.115, P=0.545], nor LV dimension changes [LVEDD 40.2 mm (SD 6.85), r = -0.192, P=0.308; LVESD 26.2 mm (SD 4.98), r=-0.266, P=0.156]. Conclusion There was no correlation between Hb level in chronically anemic children and changes in LV systolic function or dimension.

Introduction: Obesity is associated with increased epicardial adipose tissue (EAT). It is unknown if this ectopic fat deposit has direct cardiotoxic paracrine effects on regional systolic function. We have previously shown that EAT mediates diastolic dysfunction via systemic effects, rather than localized effects. We similarly hypothesized regional EAT deposits would have no effect on the left ventricular (LV) strain of adjoining myocardial segments. Methods: We studied 28 obese healthy adults (mean age 48 ± 5 yrs, BMI 38.2 ± 5.0 kg/m 2 ). EAT was quantified on each individual MRI slice from base to apex and summed to obtain total volume. It was then separated into anterior, lateral, and inferior regions corresponding to the adjacent LV segments. Using MRI feature tracking, global longitudinal LV strain (GLS) and peak regional anterior, inferior, and lateral LV strain were quantified. Associations between total EAT and GLS, and between regional EAT and corresponding regional strain were determined by linear regression. Results: Mean total EAT volume was 69.6 ± 29.8 mL and mean GLS was -19.4 ± 2.0%. Individual data points for EAT and longitudinal strain are shown in the figure. Greater total EAT volume was modestly associated with decreased GLS (r2 = 0.127). However, anterior, lateral, and inferior EAT volume did not correlate with a decrease in corresponding regional strain (r2 = 0.003, r2 = 0.088, r2 = 0.016, respectively). Conclusion: In obese adults, total EAT volume was associated with a decrease in global LV systolic function measured by GLS. There was no association between regional EAT depots and corresponding regional LV function to suggest localized metabolic cardiotoxic effect. These preliminary results support our previous findings that EAT has little paracrine effect on cardiac function. Rather, EAT likely represents an additional depot of ectopic fat reflective of a general metabolic abnormality.

Background —Long-standing aortic stenosis causes significant left ventricular (LV) dysfunction, which may progress irreversibly. In many cases, LV function can be salvaged by aortic valve surgery, although debate exists regarding the best valve prosthesis to use. Methods and Results —We studied 33 patients retrospectively who had significant aortic stenosis and impaired LV systolic function, as assessed by transthoracic Doppler echocardiography. Patients were assessed preoperatively and before discharge from the hospital. A total of 20 patients received a stentless (homograft or Toronto) valve, and 13, a stented valve. No patient had significant aortic regurgitation or other valvular disease. Preoperatively, fractional shortening was 18.8±5.5% in the stentless group and 18.6±3.8% in the stented group. Postoperatively, it was 25.6±6.9% ( P <0.001 compared with baseline) and 17.0±2.8%, respectively ( P <0.001 compared with stentless group). Fractional shortening improved because of a reduction in LV end-systolic and end-diastolic dimensions in the stentless group. Systolic long axis function at the LV free wall also recovered, with an increase in systolic excursion and both peak shortening and lengthening rates. No change was noted in mitral valve Doppler patterns. Conclusions —Patients who received a stentless valve demonstrated a significantly greater early improvement in LV systolic function compared with those who received a stented valve.
