RESUMO
AIM: we sought to test the inter-center reproducibility of 16 echo laboratories involved in the EACVI-Afib Echo Europe. METHODS: This was done on a dedicated setting of 10 patients with sinus rhythm (SR) and 10 with persistent atrial fibrillation (AF), collected by the Principal Investigator. Images and loops of echo-exams were stored and made available for labs. The tested measurements included main echo-Doppler parameters, global longitudinal strain (GLS) and peak atrial longitudinal strain (PALS). RESULTS: Single measures interclass correlation coefficients (ICCs) of left ventricular mass and ejection fraction were suboptimal in both patients with SR and AF. Among diastolic parameters, ICCs of deceleration time were poor, in particular in AF (=.50). ICCs of left atrial size and function, besides optimal in AF, showed an acceptable despite moderate concordance in SR. ICC of GLS was .81 and .78 in SR and AF respectively. ICCs of PALS were suitable but lower in 4-chamber than in 2-chamber view. By depicting the boxplot of the 16 laboratories, GLS distribution was completely homogeneous in SR, whereas GLS of AF and PALS of both SR and AF presented a limited number of outliers. GLS mean ± SE of the 16 labs was 19.7 ± .36 (95% CI: 18.8-20.4) in SR and 16.5 ± .29 (95% CI: 15.9-17.1) in AF, whereas PALS mean ± SE was 43.8 ± .70 (95% CI: 42.3-45.3) and 10.2 ± .32 (95% CI: 9.5-10.9) respectively. CONCLUSION: While the utilization of some standard-echo variables should be discouraged in registries, the application of GLS and PALS could be largely promoted because their superior reproducibility, even in AF.

BACKGROUND: The COVID-19 pandemic forces sport and exercise medicine (SEM) physicians to think differently about the clinical care of patients. Many rapidly implement eHealth and telemedicine solutions specific to SEM without guidance on how best to provide these services. AIM: The aim of this paper is to present some guiding principles on how to plan for and perform an SEM consultation remotely (teleSEM) based on a narrative review of the literature. A secondary aim is to develop a generic teleSEM injury template. RESULTS: eHealth and telemedicine are essential solutions to effective remote patient care, also in SEM. This paper provides guidance for wise planning and delivery of teleSEM. It is crucial for SEM physicians, technology providers and organisations to codesign teleSEM services, ideally involving athletes, coaches and other clinicians involved in the clinical care of athletes, and to gradually implement these services with appropriate support and education. CONCLUSION: teleSEM provides solutions for remote athlete clinical care during and after the COVID-19 pandemic. We define two new terms-eSEM and teleSEM and discuss guiding principles on how to plan for and perform SEM consultations remotely (teleSEM). We provide an example of a generic teleSEM injury assessment guide.

Three seaweeds (Halimeda tuna, Codium bursa and Cystoseira barbata) and one seagrass (Cymodocea nodosa) were collected from the Coast of Montenegro, Gulf of Boka Kotorska and their chemical analysis was performed. In seagrass C. nodosa, three phenolic compounds were identified (diosmetin 7-sulfate, caftaric and coutaric acid). The content of ß-glucan, fatty acids, sterols and micro- and macro-elements were investigated among all samples. The highest content of ß-glucan was detected in C. nodosa seagrass (13.04±0.42 g/100â g). The highest polyunsaturated fatty acids (PUFAs) level was reported in C. barbata, the brown alga (7.157â mg/g), which also had the significant sterol content (fucosterol, 21.76±0.1â µg/g). Green algae, C. bursa and H. tuna, showed the highest level of sterols (ß-sitosterol, 95.21±0.16â µg/g and 73.90±0.08â µg/g, respectively). H. tuna had the highest content of calcium (Ca) in amount of 55125â µg/g. In C. bursa, C. barbata and C. nodosa, the Na/K ratio was low (0.43, 0.46 and 0.69, respectively).

BACKGROUND: The effectiveness trial "Stress echo (SE) 2020" evaluates novel applications of SE in and beyond coronary artery disease. The core protocol also includes 4-site simplified scan of B-lines by lung ultrasound, useful to assess pulmonary congestion. PURPOSE: To provide web-based upstream quality control and harmonization of B-lines reading criteria. METHODS: 60 readers (all previously accredited for regional wall motion, 53 B-lines naive) from 52 centers of 16 countries of SE 2020 network read a set of 20 lung ultrasound video-clips selected by the Pisa lab serving as reference standard, after taking an obligatory web-based learning 2-h module ( http://se2020.altervista.org ). Each test clip was scored for B-lines from 0 (black lung, A-lines, no B-lines) to 10 (white lung, coalescing B-lines). The diagnostic gold standard was the concordant assessment of two experienced readers of the Pisa lab. The answer of the reader was considered correct if concordant with reference standard reading ±1 (for instance, reference standard reading of 5 B-lines; correct answer 4, 5, or 6). The a priori determined pass threshold was 18/20 (≥ 90%) with R value (intra-class correlation coefficient) between reference standard and recruiting center) > 0.90. Inter-observer agreement was assessed with intra-class correlation coefficient statistics. RESULTS: All 60 readers were successfully accredited: 26 (43%) on first, 24 (40%) on second, and 10 (17%) on third attempt. The average diagnostic accuracy of the 60 accredited readers was 95%, with R value of 0.95 compared to reference standard reading. The 53 B-lines naive scored similarly to the 7 B-lines expert on first attempt (90 versus 95%, p = NS). Compared to the step-1 of quality control for regional wall motion abnormalities, the mean reading time per attempt was shorter (17 ± 3 vs 29 ± 12 min, p < .01), the first attempt success rate was higher (43 vs 28%, p < 0.01), and the drop-out of readers smaller (0 vs 28%, p < .01). CONCLUSIONS: Web-based learning is highly effective for teaching and harmonizing B-lines reading. Echocardiographers without previous experience with B-lines learn quickly.

BACKGROUND: We aimed to assess the relationship between echocardiographic characteristics and mortality in patients with chronic obstructive pulmonary disease (COPD). METHODS: We prospectively studied 154 patients (mean age 71 ± 10 years, 71% male) with COPD. All patients underwent transthoracic Doppler echocardiography within 48 hours of hospital admission. Primary endpoint was all-cause mortality during a median period of 22 months. RESULTS: Mildly elevated tricuspid regurgitation pressure and mitral E/e' ratio were the most commonly encountered echocardiographic abnormalities, observed in 60% and 56% of patients, respectively. In Kaplan-Meier analysis of survival, left atrial enlargement, E/e' ratio > 8, right atrial enlargement, right ventricular dilation, decreased tricuspid annular plane systolic excursion, decreased tricuspid annular systolic velocity, and elevated tricuspid regurgitation velocity were associated with all-cause mortality (p < 0.05 for all). In the Cox proportional hazards analysis, the mitral E/e' ratio (hazard ratio 1.048; 95% confidence interval 1.001-1.096) remained an independent echocardiographic predictor of survival after adjustment for age, COPD severity, and other baseline echocardiographic parameters. CONCLUSIONS: Among patients with COPD, an abnormal mitral E/e' ratio was an independent echocardiographic predictor of all-cause mortality. Echocardiographic evaluation of structural and functional cardiac abnormalities provides important prognostic information and should be used routinely in the assessment of patients with COPD. © 2016 Wiley Periodicals, Inc.

AIMS: Contradicting reports have been published regarding the relation between a dobutamine-induced increase in either cardiac dyssynchrony or left-ventricular ejection fraction (LVEF) and the response to cardiac resynchronization therapy (CRT). Using apical rocking (ApRock) as surrogate dyssynchrony parameter, we investigated the dobutamine stress echocardiography (DSE)-induced changes in left-ventricular (LV) dyssynchrony and LVEF and their potential pathophysiological interdependence. METHODS AND RESULTS: Fifty-eight guideline-selected CRT candidates were prospectively enrolled for low-dose DSE. Dyssynchrony was quantified by the amplitude of ApRock. An LVEF increase during stress of >5% was regarded significant. Scar burden was assessed by magnetic resonance imaging. Mean follow-up after CRT implantation was 41 ± 13 months for the occurrence of cardiac death. ApRock during DSE predicted CRT response (AUC 0.88, 95% CI 0.77-0.99, P < 0.001) and correlated inversely with changes in EF (r = -0.6, P < 0.001). Left-ventricular ejection fraction changes during DSE were not associated with CRT response (P = 0.082). Linear regression analysis revealed an inverse association of LVEF changes during DSE with both, total scar burden (B = -2.67, 95CI -3.77 to -1.56, P < 0.001) and the DSE-induced change in ApRock amplitude (B = -1.23, 95% CI -1.53 to -0.94, P < 0.001). Kaplan-Meier analysis revealed that DSE-induced increase in ApRock, but not LVEF, was associated with improved long-term survival. CONCLUSION: During low-dose DSE in CRT candidates with baseline dyssynchrony, myocardial contractile reserve predominantly results in more dyssynchrony, but less in an increase in LVEF. Dyssynchrony at baseline and its dobutamine-induced changes are predictive of both response and long-term survival following CRT.

BACKGROUND: With a potential of detecting subtle myocardial injury, two-dimensional (2D) speckle tracking-derived strain could help to distinguish between ischemic and nonischemic ST-segment elevation. Little is known if limitations of strain imaging could prevent its applicability in acute cardiac care settings. CASE PRESENTATION: We present a 56-year-old male with persistent ST-segment elevation in the inferolateral leads and suspected hypokinesia of the inferior wall. Semiautomated 2D speckle tracking strain analysis showed normal longitudinal peak systolic strain (LPSS) in all segments of the inferior wall, ruling out wall-motion abnormalities in this region. Stationary reverberations and spuriously low values of LPSS in the posterolateral wall required operator's expertise to distinguish pathological myocardial deformation from artifacts. Additional workup revealed that early repolarization pattern was mistaken for the inferior wall acute myocardial infarction in our patient. CONCLUSIONS: Semiautomated quantification of regional left ventricular function by 2D speckle tracking echocardiography could facilitate decision making even in the emergency settings. Due to intrinsic limitations of this novel method, its actual clinical value in acute cardiac care settings may depend on the expertise of the operator and is yet to be determined.

Background: Patients with acute coronary syndrome (ACS) and normal electrocardiogram (ECG) may have an increased risk of late diagnosis and complications of the disease. Objective: To study the demographic, angiographic and echocardiographic characteristics of patients hospitalized for ACS in whom the ECG was normal on admission to the hospital. Methods: This retrospective study included patients who were hospitalized for ACS without ST-elevation between 2015 and 2023 and who had coronary artery disease (CAD) confirmed by coronary angiography. By further inspection of the electronic databases, patients with ACS who had a normal ECG on admission were filtered out and analyzed separately. Results: Of the total 3137 patients with suspected ACS without ST-elevation, 129 patients (4.1%) were diagnosed as having ACS with a normal ECG. In three patients a non-atherosclerotic cause for the ACS was found. A significantly higher proportion of patients had single-vessel (54.3%) compared to two-vessel (29.5%) and three-vessel (14%) CAD. In addition to a normal ECG, 5.7% of patients with single-vessel CAD and 3.5% of patients with multi-vessel CAD had normal troponin levels and normal regional LV systolic function on echocardiography. Conclusion: Less than 5% of hospitalized patients with ACS without ST-elevation had a normal ECG on admission. The majority of these patients have single-vessel CAD. In about 5% of patients with single-vessel CAD, neither elevated troponin levels nor LV asynergy are detected.

Cardiac ultrasound (CUS), either focused cardiac ultrasound (FoCUS) or emergency echocardiography, is frequently used in cardiovascular (CV) emergencies. We assessed correlations and discrepancies between CUS, clinical diagnosis and the autopsy findings in early deceased patients with suspected CV emergencies. We retrospectively analysed clinical and autopsy data of 131 consecutive patients who died within 24 h of hospital admission. The type of CUS and its findings were analysed in relation to the clinical and autopsy diagnoses. CUS was performed in 58% of patients - FoCUS in 83%, emergency echocardiography in 12%, and both types of CUS in 5% of cases. CUS was performed more frequently in patients without a history of CV disease (64 vs. 40%, p = 0.08) and when the time between admission and death was longer (6 vs. 2 h, p = 0.021). In 7% of patients, CUS was inconclusive. In 10% of patients, the ante-mortem cause of death could not be determined, while discrepancies between the clinical and post-mortem diagnosis were found in 26% of cases. In the multivariate logistic regression model, only conclusive CUS [odds ratio (OR) 2.76, 95% confidence interval (CI) 1.30-7.39, p = 0.044] and chest pain at presentation (OR 30.19, 95%CI 5.65 -161.22, p < 0.001) were independently associated with congruent clinical and autopsy diagnosis. In a tertiary university hospital, FoCUS was used more frequently than emergency echocardiography in critically ill patients with suspected cardiac emergencies. Chest pain at presentation and a conclusive CUS were associated with concordant clinical and autopsy diagnoses.

OBJECTIVE: The pre-test probability (PTP) model for obstructive coronary artery disease (CAD) was updated in 2019 by the European Society of Cardiology (ESC). To our knowledge, this model was never externally validated in a population with a high incidence of CAD. The aim of this study is to validate the new PTP ESC model in our population, which has a high CAD incidence, and to compare it with the previous PTP ESC model from 2013. METHODS: We retrospectively analysed 1294 symptomatic patients with suspected CAD referred to our centre between 2015 and 2019. In all patients, the PTP score was calculated based on age, gender, and symptoms according to the ESC model from 2013 (2013-ESC-PTP) and 2019 (2019-ESC-PTP). All patients underwent invasive coronary angiography (ICA). RESULTS: Of the 1294 patients, obstructive CAD was diagnosed in 533 patients (41.2%). The 2019-ESC-PTP model categorised significantly more patients into the low probability group (PTP < 15%) than the 2013-ESC-PTP model (39.8% vs. 5.6%, p < 0.001). Obstructive CAD prevalence was underestimated using 2019-ESC-PTP at all PTP levels (calibration intercept 1.15, calibration slope 0.96). The 2013-ESC-PTP overestimated obstructive CAD prevalence (calibration intercept -0.24, calibration slope 0.73). The discrimination measured with an area under the curve was similar for both models, indicating moderate accuracy of the models. CONCLUSION: In high-risk Serbian population, both the 2013 and 2019 ESC-PTP models had moderate accuracy in diagnosing CAD, with the 2019-ESC-PTP underestimating the prevalence of CAD and the 2013-ESC-PTP overestimating it. Further studies are warranted to establish PTP models for high-risk countries.
RESUMO
AIMS: One third of patients do not improve after cardiac resynchronization therapy (CRT). Septal flash (SF) and apical rocking (ApRock) are deformation patterns observed on echocardiography in most patients eligible for CRT. These markers of mechanical dyssynchrony have been associated to improved outcome after CRT in observational studies and may be useful to better select patients. The aim of this trial is to investigate whether the current guideline criteria for selecting patients for CRT should be modified and include SF and ApRock to improve therapy success rate, reduce excessive costs and prevent exposure to device-related complications in patients who would not benefit from CRT. METHODS: The AMEND-CRT trial is a multicentre, randomized, parallel-group, double-blind, sham-controlled trial with a non-inferiority design. The trial will include 578 patients scheduled for CRT according to the 2021 ESC guidelines who satisfy all inclusion criteria. The randomization is performed 1:1 to an active control arm ('guideline arm') or an experimental arm ('echo arm'). All participants receive a device, but in the echo arm, CRT is activated only when SF or ApRock or both are present. The outcome of both arms will be compared after 1 year. The primary outcome measures are the average change in left ventricular end-systolic volume and patient outcome assessed using a modified Packer Clinical Composite Score. CONCLUSIONS: The findings of this trial will redefine the role of echocardiography in CRT and potentially determine which patients with heart failure and a prolonged QRS duration should receive CRT, especially in patients who currently have a class IIa or class IIb recommendation.
RESUMO
In cardiac arrest survivors, postresuscitation myocardial stunning usually presents as either global left ventricular dysfunction or regional dyssynergy including the various forms of stress cardiomyopathy, in which rare variants may be difficult to diagnose. We present a patient with cardiac arrest during general anesthesia, in whom speckle tracking-derived myocardial strain helped to distinguish between the inverted variant of stress cardiomyopathy and global postresuscitation myocardial stunning.

Background: The uneven lipid-lowering statin effects and statin intolerance raise interest regarding the involvement of coadministration of statins and dietary supplements. This study aimed to evaluate the effects of octacosanol supplementation on markers of redox status in cardiovascular patients on chronic atorvastatin therapy. Methods: A double-blind, randomized, placebo-controlled, single-centre study was conducted. Redox status homeostasis parameters [i.e., advanced oxidation protein products (AOPP), pro-oxidant-antioxidant balance (PAB), total oxidant status (TOS), total antioxidant status (TAS), superoxide dismutase activity (SOD), total protein sulfhydryl (SHgroups), and paraoxonase 1 (PO N 1) activity] were assessed in 81 patients. According to favorable changes in lipid profile, patients were classified into two groups: responders (n = 35) and non-responders (n = 46), and followed for 13 weeks. A principal component analysis (PCA) was applied to explore the effect of octacosanol supplementation and the relationship between investigated parameters as predictors of responders' and non-responders' status. Results: Significant decrease in Oxy-score value was found at the endpoint compared to baseline in responders' group (21.0 (13.4-25.5) versus 15.1 (12.4-18.0); P < 0.01). PCA analysis extracted 4 significant factors in the both groups, whereas extracted factors containing "octacosanol status" variable explained 14.7% and 11.5% of the variance in responders' and non-responders' subgroups, respectively. Conclusions: Octacosanol supplementation leads to an improvement of lipid profile and markers of redox status in responders' group. New studies are needed to validate our results in order to find the best approach for personalized supplementation as a useful adjunct to standard statin therapy.
RESUMO
BACKGROUND: Traditional risk factors for cardiovascular disease (CVD) play an important role in the clinical evaluation of patients with symptoms suggestive of coronary artery disease (CAD). The utility of the diagonal earlobe crease (DELC) in predicting the presence of CAD is controversial. PURPOSE: To investigate the association between DELC, traditional CVD risk factors, and obstructive CAD. METHODS: This prospective study included 1377 patients (mean age 65⯱ 10 years, 64% male) who underwent invasive coronary angiography for suspected acute or chronic coronary syndromes. In addition to routine clinical assessment, all patients underwent visual examination of both earlobes for the presence of DELC. All assessments were made by three independent readers, with a majority vote in the case of disagreement. Obstructive CAD was defined by invasive coronary angiography as >â¯50% stenosis of the left main coronary artery or >â¯70% stenosis in any other major epicardial coronary artery. RESULTS: Bilateral DELC was observed more frequently in patients with obstructive CAD than in those without it (67% vs. 33%, pâ¯= 0.022). In the multivariate logistic regression model, bilateral DELC was independently associated with CAD (odds ratio [OR] 1.36, 95% confidence interval [CI] 1.07-1.74), along with smoking (OR 1.86, 95% CI 1.44-2.38), diabetes mellitus (OR 1.67, 95% CI 1.29-2.15), male sex (OR 2.04, 95% CI 1.61-2.58), and dyslipidemia (OR 1.54, 95% CI 1.12-2.30); however, the diagnostic accuracy of DELC was modest and resembled that of traditional CVD risk factors. CONCLUSION: Despite being independently associated with obstructive CAD, DELC is not a reliable stand-alone clinical marker of CAD due to modest diagnostic accuracy.

A randomized, double-blind, placebo-controlled study was conducted to investigate the influence of supplementation with a superoxide dismutase (SOD)-rich plant extract on markers of oxidative stress, zonulin levels and the performance of elite athletes. Participants were 30 international-level rowers, divided into an experimental group (n = 15) and a control group (n = 15). The rowers performed a maximal effort incremental test on a rowing ergometer at the beginning and at the end of the study. Markers of oxidative stress (total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), superoxide dismutase (SOD), glutathione peroxidase (GPx), advanced oxidation protein products (AOPPs), malondialdehyde (MDA), sulfhydryl (SH) groups, bilirubin, uric acid, albumin and zonulin) were determined in serum. A lower TOS (p = 0.010) and OSI (p = 0.004), a lower MDA (p = 0.001) and a higher level of SH groups (p = 0.031) were observed in the experimental group after supplementation. Physical performance was evaluated through metabolic efficiency, taking lactate levels and power output on the ergometer into account. After 6 weeks of supplementation, the relative increase in metabolic efficiency at a 4 mmol/L lactate concentration and maximal effort was significantly higher in the experimental group (p = 0.004 and p = 0.015, respectively). These results suggest that supplementation with a SOD-rich extract promotes lower oxidative stress, better antioxidant protection and, consequently, the better work performance of athletes.
RESUMO
More than 500 000 cardiovascular implantable electronic devices (CIEDs) are implanted in the European Society of Cardiology countries each year. The role of cardiovascular imaging in patients being considered for CIED is distinctly different from imaging in CIED recipients. In the former group, imaging can help identify specific or potentially reversible causes of heart block, the underlying tissue characteristics associated with malignant arrhythmias, and the mechanical consequences of conduction delays and can also aid challenging lead placements. On the other hand, cardiovascular imaging is required in CIED recipients for standard indications and to assess the response to device implantation, to diagnose immediate and delayed complications after implantation, and to guide device optimization. The present clinical consensus statement (Part 1) from the European Association of Cardiovascular Imaging, in collaboration with the European Heart Rhythm Association, provides comprehensive, up-to-date, and evidence-based guidance to cardiologists, cardiac imagers, and pacing specialists regarding the use of imaging in patients undergoing implantation of conventional pacemakers, cardioverter defibrillators, and resynchronization therapy devices. The document summarizes the existing evidence regarding the use of imaging in patient selection and during the implantation procedure and also underlines gaps in evidence in the field. The role of imaging after CIED implantation is discussed in the second document (Part 2).

Cardiac implantable electronic devices (CIEDs) improve quality of life and prolong survival, but there are additional considerations for cardiovascular imaging after implantation-both for standard indications and for diagnosing and guiding management of device-related complications. This clinical consensus statement (part 2) from the European Association of Cardiovascular Imaging, in collaboration with the European Heart Rhythm Association, provides comprehensive, up-to-date, and evidence-based guidance to cardiologists, cardiac imagers, and pacing specialists regarding the use of imaging in patients after implantation of conventional pacemakers, cardioverter defibrillators, and cardiac resynchronization therapy (CRT) devices. The document summarizes the existing evidence regarding the role and optimal use of various cardiac imaging modalities in patients with suspected CIED-related complications and also discusses CRT optimization, the safety of magnetic resonance imaging in CIED carriers, and describes the role of chest radiography in assessing CIED type, position, and complications. The role of imaging before and during CIED implantation is discussed in a companion document (part 1).

AIMS: To assess the level of transesophageal echocardiography (TOE) knowledge and skills of young cardiologists. METHODS AND RESULTS: A European Association of Cardiovascular Imaging (EACVI) online study using the first fully virtual simulation-based software was conducted in two periods (9-12 December 2021 and 10-13 April 2022). All young cardiologists eligible to participate (<40 years) across the world were invited to participate. After a short survey, each participant completed two tests: a theoretical test to assess TOE knowledge and a practical test using an online TOE simulator to investigate TOE skills. Among 716 young cardiologists from 81 countries, the mean theoretical test score was 56.8 ± 20.9 points, and the mean practical test score was 47.4 ± 7.2 points (/100 points max each), including 18.4 ± 8.7 points for the acquisition test score and 29.0 ± 6.7 points for the anatomy test score (/50 points max each). Acquisition test scores were higher for four-chamber (2.3 ± 1.5 points), two-chamber (2.2 ± 1.4 points) and three-chamber views (2.3 ± 1.4 points) than for other views (all P < 0.001). Prior participation to a TOE simulation-based training session, a higher number of TOE exams performed per week, and EACVI certification for TOE were independently associated with a higher global score (all P < 0.001). CONCLUSION: Online evaluation of young cardiologists around the world showed a relatively low level of TOE skills and knowledge. Prior participation to a TOE simulation-based training session, a higher number of TOE exams performed per week, and the EACVI certification for TOE were independently associated with a higher global score.
