Abstract Kawasaki disease is an autoimmune process, which characterizes with the engagement of arteries and especially - the coronary arteries of the heart.The aim of the study was to assess global and regional LV myocardial function and to predict the long-term prognosis of Kawasaki disease.Design and method: We analyzed 62 children (mean age 9,4 ±3,9 years ), 28 of them with a residual coronary aneurism and 20 healthy children ( mean age 9,6 ±4, 8). The myocardial deformation indexes of the LV – global and regional longitudinal, circumferential and radial stain were analyzed. The patients are divided into groups according to the type of treatment and the occurrence of complications - residual aneurysms. Apical, middle and basal short axis for 2D images were acquired (65 ± 7 frames/s) in addition to apical four, three and two-chamber views. Global and regional peak systolic strain - longitudinal, radial and circumferential of the LV was derived and the strain curves (eLL, eCC, eRR) were extracted using a commercial softwareResults: Global longitudinal strain measurements of the LV were non-significantly different between the Kawasaki group without an aneurysm and normals (GLS -19,81± 1,91% vs -19,69 ± 1,91%) In the group of Kawasaki with an aneurysm was found significantly reduced GLS compared to healthy patients (-17,25 ± 3.48% vs -19,69± 1,81%. ). Concerning the regional analysis,in the group with aneurysms, the radial, circumferential and longitudinal strain were significantly reduced, especially on the basal and middle LV-segments. Conclusion Decreased myocardial strain values are signs of regional hypokinesia with a possible local segmental ischemia in the group with coronary aneurysms on coronary artery and are marker for developing severe LV dysfunction in the future. The contribution in this study was the introduction of a new non-invasive assessment of myocardial function after Kawasaki disease, despite the apparently "normal" global systolic heart function.

Cardiac magnetic resonance (CMR)-derived left ventricular (LV) global longitudinal strain (GLS) provides incremental prognostic information on various cardiovascular diseases but has not yet been investigated comprehensively in patients with Takotsubo syndrome (TS). This study evaluated the prognostic value of feature tracking (FT) GLS, tissue tracking (TT) GLS, and fast manual long axis strain (LAS) in 147 patients with TS, who underwent CMR at a median of 2 days after admission. Long-term mortality was assessed 3 years after the acute event. In contrast to LV ejection fraction and tissue characteristics, impaired FT-GLS, TT-GLS and fast manual LAS were associated with adverse outcome. The best cutoff points for the prediction of long-term mortality were similar with all three approaches: FT-GLS −11.28%, TT-GLS −11.45%, and fast manual LAS −10.86%. Long-term mortality rates were significantly higher in patients with FT-GLS > −11.28% (25.0% versus 9.8%; p = 0.029), TT-GLS > −11.45% (20.0% versus 5.4%; p = 0.016), and LAS > −10.86% (23.3% versus 6.6%; p = 0.014). However, in multivariable analysis, diabetes mellitus (p = 0.001), atrial fibrillation (p = 0.001), malignancy (p = 0.006), and physical triggers (p = 0.006) outperformed measures of myocardial strain and emerged as the strongest, independent predictors of long-term mortality in TS. In conclusion, CMR-based longitudinal strain provides valuable prognostic information in patients with TS, regardless of the utilized technique of assessment. Long-term mortality, however, is mainly determined by comorbidities.

Purpose: Measuring myocardial strain using two-dimensional speckle tracking echocardiography has emerged as a new tool to identify subclinical ventricular dysfunction. Abnormal strain has been shown to have superior sensitivity compared with dobutamine stress echocardiography for viability assessment; however, there is a paucity of data regarding the prediction of long-term major adverse cardiac events. We compared the prognostic ability of both global longitudinal strain (GLS) from resting echocardiograms to regional wall motion score index (WMSI) from stress echocardiograms in their ability to predict long-term major adverse cardiac events. Methods: Patients referred for stress echocardiography, who also underwent coronary angiography within 3 months of stress echo (n=122), were enrolled. Patients with reduced ejection fractions (<40%) were excluded. Patients were followed for a median of 3.4 years for major adverse cardiac events, readmissions and repeat cardiac testing. Results: Patients with abnormal GLS (GLS <16.8%) from the resting echocardiogram obtained as part of the exercise echocardiogram experienced a significantly shorter time to major adverse cardiac events (p=0.026), first cardiovascular hospitalization and repeat cardiac testing (p=0.0011) compared to those with normal GLS. Abnormal GLS appears to be a better predictor than abnormal WMSI in predicting major adverse cardiac events (p=0.174) and time to first cardiovascular hospitalization or repeat cardiac testing (p=0.0093). Conclusion: GLS may be a better predictor of long-term major adverse cardiac events, readmissions and repeat cardiac testing than WMSI in patients undergoing stress echocardiography.

Background  Myocardial deformation integrated with cardiac dimensions provides a comprehensive assessment of the ventricular remodelling patterns induced by cumulative effects of intensive exercise. Feature tracking(FT) can measure myocardial deformation from cardiac magnetic resonance(CMR) cine sequences; however, its accuracy is still scarcely validated. Purpose  Our aim was to compare FT’s accuracy and reproducibility to speckle tracking echocardiography (STE) in highly trained endurance athletes (EAs). Methods  93 EAs (&gt;12 hours training/week during the last 5 years, 52% male, 35 ± 5.1 years) and 72 age-matched controls underwent a resting CMR and a transthoracic echocardiography to assess biventricular exercise-induced remodelling and biventricular global longitudinal strain (GLS) by CMR-FT and STE. Results   High endurance training load was associated with larger bi-ventricular and bi-atrial sizes and mildly reduced systolic function of both ventricles (p &lt; 0,05). Strain values (both by CMR-FT and STE) proportionally decreased with increasing ventricular volumes potentially depicting the increased volume and functional biventricular reserve that characterize EAs heart. Strain values were lower when assessed by CMR-FT as compared to STE (p &lt; 0.001), with good reproducibility for the LV (bias = 3.94%, LOA= ± 4.27%) but wider variability for RV strains (Figure 2). Conclusions   Biventricular longitudinal strain values were lower when assessed by FT compared to STE. Both methods were comparable when measuring LV strain but not RV strain. These differences might be justified by FT’s lower in-plane spatial and temporal resolution, which is particularly relevant for the complex anatomy of the RV. Abstract Figure. Fig 1.

Introduction: The paediatric inflammatory multisystem syndrome temporally associated with SARS-CoV-2 (PIMS-TS) and Kawasaki disease (KD) have overlapping features. This study aimed to describe the strain segmental analysis among both entities. Methods: Retrospective review of strain segmental analysis within 4 weeks of presentation of symptoms among children diagnosed with PIMS-TS between April and June 2020 and a historic cohort of typical KD from the Royal Brompton Hospital, London. Results: We included 33 PIMS-TS patients (23 males, 69.7%) at a mean age of 8 ± 4,9 years old and 45 KD patients (31 males, 68,9%) at a mean age of 5,8 ± 4,5 years old. PIMS-TS patients were older at presentation (p = 0.038). Left ventricle ejection fraction (LVEF) was normal in both groups (63,3% vs 63,5%; p= 0,89), 4/33 PIMS-TS children (12,1%) had coronary arteries abnormalities (CAA), whereas 100% of KD cohort had CAA. Both groups had a normal global longitudinal strain (GLS), but in PIMS-TS it was significantly reduced compared to the KD group (-20% vs -22%; p=0,008). Basal segments were the most affected in PIMS-TS with significant difference in the basal anterior and anterolateral strain compared to KD (respectively -18,2% vs -23,4%; p < 0,001 and - 16,7% vs -22,7%; p < 0,001). PIMS-TS had a greater anterior, anterolateral and posterior segments involvement with a significant reduction in the anterolateral mid-wall longitudinal strain (-18,3% vs -22%; p=0,002). Apical segments were less involved, with a significant difference only in the septal and inferior apical strain (respectively p=0.001 and p=0,032). Conclusions: These preliminary data showed that after 4 weeks from the onset of symptoms, all PIMS-TS patients had a normal LVEF but they had a significant reduction in GLS and different segmental involvement compared to KD cohort. We hypothesize that these findings may be related to direct myocardial damage in PIMS-TS rather than caused by coronaries perfusion abnormalities.

Background: Recent epidemiological studies have suggested that some patients with Kawasaki disease (KD) have an atopic tendency. However, it is not clear what the long-term prognosis will be for KD-patient with allergic disease. We aim to investigate the long-term prognosis of KD-patient with allergic disease. Subjects & Methods: We studied a cohort of KD-patient (n=58, follow-up age; 9.95±1.84 years), in whom we examined total serum IgE and specific IgE at KD-onset (onset age; 2.13±1.84 years). Using retrospective patient medical record analysis, we evaluated the prevalence of bronchial asthma at onset and follow-up of KD. In addition, we examined the hospitalization rate, medical history and family history in pediatric bronchial asthma after KD-onset. Results: In our study, KD-patient had markedly higher total serum IgE and prevalence of bronchial asthma at onset of KD than the general children’s population, as reported by Japanese national government (Table 1). The prevalence of bronchial asthma at follow-up was similar to the general children’s population. 9 children had already had a diagnosis of a bronchial asthma at KD-onset. 8 children had subsequently developed bronchial asthma after KD-onset. In these 2 groups, however, 6 and 8 children, respectively, had remitted during follow-up. Nobody was hospitalized for asthmatic exacerbation after KD-onset. Conclusions: These findings demonstrate that KD-patient with atopic bronchial asthma at onset have not developed severe allergic reaction. There results provide that the pathogenic mechanism of KD might weakly or transiently provoke an elevation of total IgE and the developing of allergies.

Abstract Funding Acknowledgements ESC Training Grant 2019 Background Non-invasive prediction of critical coronary artery stenosis (CCS) is challenging. CCS may cause persistent impaired longitudinal function at rest, which could be detected by two-dimensional speckle tracking echocardiography (2D-STE). However, strain parameters are load dependent, hence they might not reflect systolic function accurately. A novel non-invasive method to calculate MW recently showed a strong correlation with invasive work measurements. Objectives To investigate the ability of non-invasive Myocardial Work (MW) indices: 1) to identify the ischaemic risk area during acute coronary occlusion (ACO); 2) to predict the ischaemic risk area underlying a CCS before coronary angiography. Methods The study population comprises 80 individuals: fifty consecutive patients (pts) referred for coronary angiography in a single tertiary coronary care centre and thirty controls (CTRL). Echocardiography recordings (GE-Healthcare) with systolic and diastolic non-invasive pressures, were obtained immediately before coronary angiography, during ACO, and immediately after revascularization to measure longitudinal strain along with myocardial work indices: Myocardial Work Index (MWI), Myocardial Constructive Work (MCW), Myocardial Wasted work (MWW), Myocardial work efficiency (MWE). Results Compared to baseline, we found a significant reduction of global longitudinal strain (GLS) (p = 0.005), MWI, MCW and MWE (p &lt; 0.001) during ACO. After the procedure, we observed a significant improvement in GLS, MWI, MCW and MWE (p &lt; 0.001) compared to the findings obtained during CO. Interestingly, baseline global MWI, MCW and MWE were significantly reduced in pts with CCS at angiography compared to controls (p &lt; 0.05). Moreover, regional MWE, but not longitudinal strain, measured within the myocardial segments underlying the CCS, was significantly reduced compared to non-target segments (p &lt; 0.001). Conclusions Our results demonstrate that non-invasive estimation of regional and global MW parameters are able to identify myocardial ischemia upon ACO. Moreover, myocardial work indices measured at rest were able to predict the presence of CCS before invasive angiography, whereas MWE was more sensitive than myocardial strain to document regional impairment of myocardial function.
