Abstract
INTRODUCTION Early signs of subclinical cardiac damage must be identified before they turn into clinical manifestations. Tailoring a formula is relevant for precise QTc evaluation in childhood acute lymphoblastic leukemia (ALL) survivors considering they are at risk of long-term cardiac problems. Therefore, we aim to develop group heart rate correction formulas for QT intervals in childhood ALL survivors at rest and during exercise, and to assess the applicability of these methods across a variety of risk groups exposed to diverse chemotherapy dosages. METHODS Two hundred and fifty childhood ALL survivors in the PETALE study were classified into 3 groups depending on their prognostic risk group. ECG measurements (QT and RR intervals) were made at rest and during a cardiopulmonary exercise test. QT correction for heart rate was applied using 5 different formulas, which included 2 previously published formulas and 3 group-specific formulas for each sex. RESULTS The QT/RR relation showed 2 different curves between rest and during exercise, which was worse for females. Group-specific QTc formulas allowed adequate heart rate-corrected QT interval, independently of the cumulative dose of doxorubicin received during treatment. Group-specific formulas showed significantly shorter QTc intervals than QTc from Bazett's formula. QTc (Bazett's formula) values surpassed the established clinical norm in 22 males (11%) and 22 females (11%), with a majority occurring during exercise, affecting 15 males (7.5%) and 10 females (5%). CONCLUSION This study shows the applicability of personalized group correction of QT/RR data in childhood ALL survivors. Our comprehensive assessments (spanning rest, exercise, and recovery) is an effective approach for risk stratification of cardiac complications in childhood ALL survivors.

Abstract
BACKGROUND Conflicting results have been described in the scientific literature regarding the relationship between electrocardiographic parameters and complications in patients with Takotsubo syndrome (TTS). Aim of the present study was to investigate whether there is an association between markers of ventricular repolarization and major adverse cardiovascular events (MACE) during hospitalisation. METHODS A retrospective chart review was conducted on a sample of patients with diagnosis of TTS, based on the fulfilment of the revised Mayo Clinic criteria. MACE included acute heart failure, cardiogenic shock, sustained ventricular tachycardia, ventricular fibrillation, and death. The following parameters, assessed on the admission electrocardiogram, were analysed: ST-segment elevation, ST-segment depression, T wave inversion, presence of Q waves, QT interval, QT interval corrected for heart rate, QT-dispersion, Tpeak-Tend (Tpe) interval, Tpe dispersion, Tpe/QT ratio, and QTpeak/QT ratio. RESULTS Patients with MACE, compared to patients without MACE, showed more commonly anterior ST-segment elevation and had significantly higher values of Tpe/QT ratio. Low ejection fraction and Tpe/QT ratio > 0.27 identified a sub-population of patients more likely to have MACE during hospitalisation. CONCLUSIONS Tpe/QT ratio represents a useful electrocardiographic parameter in the acute phase of TTS.

Abstract
Kawasaki disease (KD) is the leading cause of acquired heart disease in children. In addition to coronary artery abnormalities, aneurysms and myocarditis, acute KD is also associated with echocardiogram (ECG) abnormalities in 40-80% of patients. Here, we show that these ECG changes are recapitulated in the Lactobacillus casei cell wall extract (LCWE)-induced KD vasculitis mouse model. LCWE-injected mice developed elevated heart rate and decreased R wave amplitude, with significant differences in prolonged ventricular repolarization. LCWE-injected mice developed cardiac ganglion inflammation, that may affect the impulse-conducting system in the myocardium. Furthermore, serum nerve growth factor (NGF) was significantly elevated in LCWE-injected mice, similar to children with KD vasculitis, associated with increased neural remodeling of the myocardium. ECG abnormalities were prevented by blocking interleukin (IL)-1 signaling with anakinra, and the increase in serum NGF and cardiac neural remodeling were similarly blocked in Il1r1-/- mice and in wild-type mice treated with anakinra. Thus, similar to clinical KD, the LCWE-induced KD vasculitis mouse model also exhibits electrophysiological abnormalities and cardiac neuronal remodeling, and these changes can be prevented by blocking IL-1 signaling. These data support the acceleration of anti-IL-1 therapy trials to benefit KD patients.

Abstract
UNLABELLED Introduction Pressure overload increases in patients with moderate aortic valvular stenosis during exercise. In the absence of symptoms, it remains difficult, however, to discriminate patients for surgery based only on pressure overload. Other parameters, such as the dispersion of ventricular re-polarisation (d-QT), which reportedly increases with the transvalvular pressure gradient, have not been fully studied in this condition. OBJECTIVE To determine the pattern of QT and d-QT response to exercise testing in children with moderate aortic valve stenosis in order to evaluate the impact of pressure overload from an electrophysiological perspective. Materials and methods In all, 15 patients were compared with 15 controls paired for age (14.8±2.5 versus 14.2±1.5 years old) and gender (66.7% male). All the patients underwent exercise stress testing with 12-lead electrocardiograph recording. QT was measured from the onset of QRS to the apex (QTa) at rest, at peak exercise, and at 1 and 3 minutes upon recovery. QT was corrected using the Fridericia equation, and d-QT was calculated. RESULTS Resting QTc was similar among the study groups, but increased significantly in study patients compared with the control group at maximal effort (p=0.004) and after 1 (p<0.001) and 3 (p<0.001) minutes of recovery. A significant association was identified between groups for d-QT (p=0.034), and post-hoc tests revealed a significant difference only at rest (p=0.001). CONCLUSIONS Ventricular re-polarisation abnormalities can be unmasked and highlighted by the assessment of electrical re-polarisation during exercise challenge in patients with asymptomatic moderate aortic valve stenosis. Using QT response to exercise could be beneficial for better optimisation of risk stratification in these patients.

Abstract
Multiple cardiovascular sequelae have been reported late after Kawasaki disease (KD), especially in patients with coronary artery lesions. In this perspective, we hypothesized that exercise response was altered after KD in patients with coronary aneurysms (CAA-KD) compared to those without history of coronary aneurysms (NS-KD). This study is a post hoc analysis of exercise data from an international multicenter trial. A group of 133 CAA-KD subjects was compared to a group of 117 NS-KD subjects. Subjects underwent a Bruce treadmill test followed to maximal exertion. Heart rate (HR), systolic blood pressure (SBP), and diastolic blood pressure (DBP) were assessed at each stage of the test including recovery. Myocardial perfusion was evaluated by stress and rest Tc-99m sestamibi SPECT imaging. Endurance time was similar between NS-KD and CAA-KD (11.3 ± 2.6 vs. 11.0 ± 2.6 min; p = 0.343). HR, SBP, and DBP responses to exercise were similar between groups (p = 0.075-0.942). Myocardial perfusion defects were present in 16.5 % CAA-KD versus 22.2 % NS-KD (p = 0.255). Analysis based on myocardial perfusion status identified a lower heart rate at 1 min into recovery as well as lower DBP at 1 and 5 min into recovery in patients with abnormal SPECT imaging (p = 0.017-0.042). Compared to patients without CA involvement, the presence of coronary aneurysms at the subacute phase of KD does not induce a differential effect on exercise parameters. In contrast, exercise-induced myocardial perfusion defect late after the onset of KD correlates with abnormal recovery parameters.

Abstract
Kawasaki disease (KD) is an acute medium vessel vasculitis seen in children. Coronary artery abnormalities are the most notable long-term complications. Intravenous immunoglobulin therapy has led to significant reduction in incidence of coronary aneurysms. However, higher risk of cardiovascular disease has been noted even in those children who have never been reported to develop coronary artery aneurysms during the subacute phase. Noninvasive estimation of this cardiovascular risk is useful in initiating timely preventive strategies. Arterial stiffness has been shown to be an independent predictor of cardiovascular events in general population. This study was aimed at measuring abdominal aorta stiffness in a cohort of children with KD from North India. Thirty children diagnosed to have KD at least 5 years prior to enrollment were evaluated by echocardiography for cardiac and abdominal aorta studies. Electrocardiographs were done in all patients for QT dispersion. There was a noticeable trend toward lower aortic strain, higher pressure strain elastic modulus and normalized pressure strain elastic modulus in children in the study group, though this difference did not reach statistical significance. Mean corrected QT dispersion was significantly higher in cases compared with controls. On cardiac evaluation, none of the subjects had any residual coronary artery involvement. A trend toward lower distensibility and higher stiffness of abdominal aorta was seen in cases compared with controls, though it was not found to be statistically significant. This could be a predictor of premature atherosclerosis in long term. Significantly higher QT dispersion was seen in cases compared with controls. More multicentric studies with larger sample size and longer follow-up periods are needed to clarify this issue.
