Circulation, Volume 150, Issue Suppl_1, Page A4143723-A4143723, November 12, 2024. Introduction:Thrombocytosis, sometimes extreme, after acute Kawasaki disease (KD) is common and felt to be pathognomonic of this diagnosis, although has also been reported after multisystem inflammatory syndrome in children (MIS-C), a clinically similar condition. We sought to determine differences in factors associated with thrombocytosis for each condition.Methods:From 01/2020 to 10/2023 across 41 sites in 8 countries from the International KD Registry, 1674 MIS-C and 1290 contemporaneous KD patients with adequate laboratory data were included in the analysis. Age-related cutpoints (derived from the CALIPER Study of normal children/adolescents; AJCP 2020; 154:342) were applied to peak platelet counts to define thrombocytosis (age 647 x109/L; age 1 to 434; age 12 to 371). Associations of demographic, clinical, laboratory and outcome factors with thrombocytosis were determined for each diagnosis group.Results:Thrombocytosis was more prevalent after KD (57%) than MIS-C (49%; p

Circulation, Volume 150, Issue Suppl_1, Page A4142337-A4142337, November 12, 2024. Background:We previously demonstrated a significantly increased inpatient mortality of COVID-19 infection-induced male Takotsubo (TTS) patients during the early pandemic period. Since then, our management of COVID-19 prevention and treatment have evolved significantly, reducing both hospitalization and mortality rates. With these advancements, we have analyzed the clinical characteristics and outcomes of reported COVD-19-associated TTS patients since the initial pandemic.Research Question:What are the clinical characteristics and mortality outcomes of COVID-19-associated TTS patients especially in the context of improved prevention and treatment?Aims:To identify clinical characteristics and outcome correlates in patients with COVID-19-associated TTS.Methods:We completed a systematic review of 191 patients with TTS from 95 published case reports, 13 case series, and 4 observational cross-sectional/cohort studies published from April 1, 2020 to May 1, 2024 (PubMed). We performed clustering analysis using the clinical, imaging, and inpatient mortality data of 78 patients, which categorized groups of patients based on how closely associated or similar they are relative to other groups. Following this, we applied feature analysis to identify which features contributed the most to the clustering results.Results:Of all TTS cases, the mean age was 64.2±16.1 with 32.9% males. A total of 122 (63.9%) had COVID-19 infection, 21 (11.0%) had COVID-19 vaccination, and 50 (26.2%) patients had other triggers (2 patients had both COVID-19 infection and a non-infectious trigger). In-hospital mortality was 28.6% (16 of 56) for males and 13.2% (15 of 114) for females (p-value = 0.01). There was no association between COVID-19 vaccine administration and in-hospital mortality (0%, 0 of 21). There were notable differences in the clinical and demographic characteristics of TTS patients before and after September 2021 based on clustering analysis. Feature analysis indicated that COVID-19-induced TTS strongly correlated with in-hospital mortality and long-term adverse outcome in male patients.Conclusion:More male TTS patients were found during the pandemic than is expected of the traditional TTS archetype. A triad of “male, COVID-19 infection and TTS” appears to predict higher inpatient mortality. Compared to our prior study, inpatient mortality rates for TTS COVID patients have declined for all groups. Vaccine-induced TTS is associated with a benign clinical phenotype.

Circulation, Volume 150, Issue Suppl_1, Page A4127513-A4127513, November 12, 2024. Background:SARS-CoV-2 infection affects the cardiopulmonary system in both the acute and long-term phase. This study aimed to comprehensively assess symptoms and potential long-term impairments 6, 18 and 30 months in patients previously hospitalized for severe Covid-19 infection.Methods:This prospective registry included patients hospitalized for PCR-confirmed Covid-19 infection. Approximately 6 months post-discharge, follow-up examination included patient history, clinical examination, echocardiography, electrocardiogram, cardiac magnetic resonance imaging (cMRI), chest computed tomography (CT) scan, pulmonary function test (PFT), six-minute walk test (6MWT) and a comprehensive laboratory panel. Patients with pathologic findings during the first visit underwent a second (at 18 months) and third (at 30 months) follow-up examination. Those without pathologic findings or who refused further medical examinations were contacted via phone to inquire about symptoms.Results:Between July 2020 and April 2022, 200 patients (91% general ward, 9% intensive care unit) were recruited. Due to dropouts, the second visit was conducted in 170 patients, and the third visit in 139 (74 in person, 65 via telephone). Long Covid criteria were fulfilled by 73% at 6 months, 52% at 18 months and 49% at 30 months post-discharge, with fatigue being the most common symptom (Figure 1). Echocardiography at 6 months showed impaired left ventricular function in 15 patients, with normalization in 80% at 18 months and further 66% at 30 months (Figure 2). cMRI revealed pericardial effusions in 28 patients at 6 months, which resolved in 47% at 18 months and in further 60% at 30 months. Signs of peri- or myocarditis were present in 7 patients at 6 months and were resolved in all 4 patients who attended control studies at 18 months. Chest CT scans at 6 months identified post-infectious residues in 41 patients, with full recovery in 20% at 18 months without further normalization after 30 months.The length of in-hospital stay was identified as a significant predictor for persisting Long Covid 6 months after discharge (95% CI: 1.005 – 1.12, p=0.03).Conclusion:While the prevalence of Long Covid decreased over time, a significant symptom burden persisted at 6, 18 and even 30 months after severe Covid-19 infection. Structural and functional abnormalities were less frequent compared to reported symptoms, posing a challenge in substantiating the causes of these symptoms.

Circulation, Volume 150, Issue Suppl_1, Page A4139661-A4139661, November 12, 2024. Introduction:Troponin-defined myocardial injury or N-terminal pro-B-type natriuretic peptide (NT-proBNP) elevation frequently coincides with coronavirus disease 2019 (COVID-19). Our prior study (COVID-MI Registry Cohort-1) confirmed that high-sensitive troponin I (HsTnI) and NT-proBNP effectively stratified mortality risk. However, variants of severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) change rapidly, and it remains unclear whether these biomarkers are consistently effective in predicting prognosis of COVID-19 patients irrespective of epidemic periods.Research Questions:Can HsTnI or NT-proBNP stratify mortality risk in recent COVID-19 cohorts?Aims:To assess the potential of HsTnI and NT-proBNP levels for risk stratification in the recent COVID-19 waves.Methods:In the COVID-MI Registry Cohort-2, we enrolled 1115 consecutive COVID-19 patients admitted between October 2021 and October 2022, during the Omicron variant endemic. We collected data of HsTnI or NT-proBNP levels from hospital charts or using the samples in our hospital’s serum/plasma bank if the data were not available. The primary outcome measure was all-cause mortality.Results:On admission, more than one-third of patients were classified as having severe COVID-19. HsTnI and NT-proBNP levels were available for 427 and 414 patients, respectively. The median HsTnI and NT-proBNP levels were 16 (interquartile range [IQR]: 5-57) ng/L and 524 (IQR: 140-2056) pg/mL, respectively. We stratified the patients into three groups by HsTnI level:

Circulation, Volume 150, Issue Suppl_1, Page A4134935-A4134935, November 12, 2024. Introduction:Recent data demonstrated that the COVID-19 pandemic adversely affected cardiovascular fellows in training (cFIT) and faculty in terms of educational disruption and search for job prospects, respectively. However, less is known about the pandemic’s effect on cFIT and faculty in terms of general well-being, shifts in personal and professional priorities, quantitative measures of stress levels, and research productivity.Methods:A national survey targeting cFIT and faculty was developed to assess the effect of the pandemic two years later on these parameters. Fifty-four participants, including 21 cFIT and 33 faculty, responded to the survey. The survey was distributed between October 2021 and May 2022 to program directors of ACGME-accredited general cardiology fellowship programs in the United States.Results:30% of cFITs perceived impaired clinical training during the pandemic; 36% of fellows experienced a decline in their clinical skills in the cardiac catheterization lab, while 27% experienced a decrease in their echocardiographic skills. Additionally, a significant percentage of cFIT reported negative interference in their competencies in nuclear cardiology (27%) and electrophysiology (12%). Most participants (76%), including faculty and fellows, reported several health issues such as sleep problems, low energy, changes in appetite, difficulty concentrating, and restlessness due to the pandemic. 43% of the faculty and 61% of cFIT reported high rates of impaired short-term productivity (Figure).Conclusion:In this national survey, we found that two years after the onset of the COVID-19 pandemic, cardiology fellows and faculty continued to experience significant concerns for decreased hands-on training and diminished research productivity. While faculty were not distressed regarding decreased clinical competencies, concerns about short-term and long-term research productivity persisted. Faculty and fellows all experienced increased stress levels and impaired productivity. Although limited by a small sample size, which can introduce bias, these results signal the importance of performing a follow-up study on the impact of COVID-19 on wellness as well as the impact on career.

Circulation, Volume 150, Issue Suppl_1, Page A4137878-A4137878, November 12, 2024. Background:The COVID-19 pandemic in 2020 was marked by a sharp decrease in out-of-hospital cardiac arrest (OHCA) survival. Whether OHCA survival has recovered to pre-pandemic levels, and whether changes in OHCA survival are similar across communities of different racial and ethnic composition, is unknown.Methods:We included adult patients with non-traumatic OHCA from 2015-2022 in the Cardiac Arrest Registry to Enhance Survival registry. Using hierarchical multivariable regression, we calculated risk-adjusted rates of survival to hospital discharge during 2015-2019 (reference period) and compared this to survival rates during 2020, 2021, and 2022. We also examined whether the trajectory of survival over this period differed based on the racial/ethnic composition of the community served by the emergency medical service (EMS) agency, defined as predominantly White ( >80% White residents), majority Black or Hispanic ( >50% Black or Hispanic residents), or integrated (neither).Results:Of 485,079 patients with OHCA, mean age was 61.9 years; 64% were male, and 22% were of Black race with 7% of Hispanic ethnicity. Overall, risk-adjusted survival rates to hospital discharge for OHCA decreased from 10.1% in 2015-2019 to 8.4% in 2020 (P

Circulation, Volume 150, Issue Suppl_1, Page A4141163-A4141163, November 12, 2024. Background:The rising incidence of stroke among young adults is partly explained by underdiagnosis of risk factors such as hypertension. Current blood pressure cutoff values for hypertension diagnosis in adolescence are not based on cardiovascular outcomes and lack specificity for sex, even though female adolescents have lower blood pressure values.Methods:A nationwide, population-based, retrospective cohort study including data of all Israeli adolescents (16-19 years) who were evaluated prior to mandatory military service in 1985 through 2013. The medical evaluation included routine measurements of height, weight, and blood pressure. The primary outcome was the first occurrence of a stroke at a young age (≤52 years) as documented in the National Stroke Registry. Cox proportional hazard models were applied separately for males and females and adjusted for adolescent body mass index and sociodemographic variables. Diabetes status in adulthood, as documented in the National Diabetes Registry, was also accounted. Several sensitivity analyses were conducted, including the evaluation of ischemic stroke cases only as the outcome and stroke occurrence at a very young age (≤45 years).Results:The cohort comprised 1,897,048 adolescents (42.4% females). During 11,355,476 person-years of follow-up, there were 1,470 first stroke events, 1,233 (83.8%) cases were of ischemic etiology. In male adolescents, a diastolic blood pressure of ≥80 mmHg was associated with an adjusted hazard ratio (aHR) for stroke at a young age of 1.28 (95% confidence interval 1.05-1.58) (Image 1). In male adolescents with blood pressure of 70-79 mmHg, the aHR was comparable to that of the reference group (

Circulation, Volume 150, Issue Suppl_1, Page A4143772-A4143772, November 12, 2024. Introduction:Mitral valve prolapse (MVP) is the most common cause of primary mitral regurgitation and is estimated to affect between 1-3% of the general population. A subset of individuals with MVP develop malignant arrhythmias, often in the context of myocardial fibrosis. The genetics of MVP, and genetic factors explaining why only some individuals with MVP have adverse outcomes, remains poorly understood.Methods:We defined MVP using a combination of claims data and echocardiographic diagnosis across 15 cohorts spanning 5 countries and performed a meta-analysis of genome-wide association studies (GWAS) for MVP including 19,487 MVP cases among 2,247,054 individuals. Causal genes were prioritized using a combination of methods including the identification of variants in active promoters/enhancers using mitral valve ATAC-seq data from an external dataset. To determine whether prioritized genes may be differentially expressed in myocardial fibrosis, we compared single-cell RNA sequencing between fibrosed papillary muscles and normal left ventricular among two individuals with severe MVP.Results:There were 67 unique genome-wide significant (GWS; p

Circulation, Volume 150, Issue Suppl_1, Page A4139757-A4139757, November 12, 2024. Background:The COVID-19 pandemic has significantly exacerbated sleep problems. Pandemic-related lockdowns and drastic changes in daily life have disrupted sleep patterns, resulting in a marked increase in sleep disturbances.Research questions:This study aims to investigate the primary factors contributing to the increase in sleep disturbances during the COVID-19 pandemic in Korea. By utilizing nationally representative data encompassing various variables, this study seeks to identify COVID-19-related factors associated with sleep disturbances during the pandemic.Method:We analyzed data from the nationally representative Korea Community Health Survey conducted in 2020, including 216,809 adults. Changes in daily life due to COVID-19 were assessed by asking participants to score their current situation compared to their pre-pandemic situation, ranging from 100 (no change) to 0 (complete cessation of daily activities). COVID-19 concerns were assessed with five questions: 1) fear of contracting the virus; 2) fear of mortality if infected; 3) fear of blame from others; 4) concerns about the health of vulnerable family members; and 5) concerns about economic impacts. Sleep disturbances were defined as sleeping 5 hours or less per night on average. Logistic regression analyses with a complex sample design were performed to examine the relationship between COVID-19-related factors and sleep disturbances, adjusting for socioeconomic and health-related variables.Results:A high level of lifestyle changes due to COVID-19 (OR = 1.15, 95% CI = 1.11–1.19) and high COVID-19 concerns (OR = 1.04, 95% CI = 1.01–1.08) were associated with an increased likelihood of sleep disturbances. Conversely, resting during COVID-19 symptoms (OR = 0.81, 95% CI = 0.76–0.87), having support during quarantine (OR = 0.93, 95% CI = 0.89–0.97), and trust in the government and neighbors (OR = 0.92, 95% CI = 0.89–0.96) were associated with a decreased likelihood of sleep disturbances.Conclusion:These findings suggest that sleep disturbances during the COVID-19 pandemic were mediated by lifestyle disruptions and high levels of concern. Social support and trust mitigated the impact of COVID-19-related risk factors. As part of preparedness, improving the environment to facilitate adequate rest during illness, ensuring strong social support, and fostering high levels of trust in the government and neighbors may be important to protect sleep health during future public health emergencies.

Circulation, Volume 150, Issue Suppl_1, Page A4141859-A4141859, November 12, 2024. Background:Field activation of patients with ST-segment elevation myocardial infarction (STEMI) by Emergency Medical Services (EMS) during the COVID-19 (COVID) pandemic era involved a change in policy whereby patients underwent COVID-19 testing in the emergency department (ED) prior to Percutaneous Coronary Intervention (PCI) versus bypassing the ED to the Catheterization (Cath) Lab.Research Question:We aimed to compare In-Hospital Mortality and other performance metrics of field activated STEMI patients at a large rural health system during the COVID era to pre and post pandemic periods.Methods:Retrospective single-center (Essentia Health, Duluth, MN, USA) cohort study of consecutive patients with STEMI activation identified in the field by EMS prior to the COVID era (5/27/2018–3/26/2020), during the 22 months of the COVID testing policy (3/27/2020–1/25/2022), and post-COVID when ED bypass resumed (1/ 26/2022–11/26/2023). The main outcomes of this study were in-hospital mortality and common STEMI system performance metrics.Results:A total of 373 consecutive field activated STEMI cases were included (pre COVID [N =132], COVID [N = 104], post COVID [N = 137]). Pre COVID, 40.9% of EMS activated STEMI cases stopped in the ED prior to the Cath Lab, 97.1% during the COVID era, and 51.1% in the post-COVID era (p

Introduction
Post-COVID-19 condition, or syndrome, also known as long COVID, is an infection-associated chronic condition that can develop after a SARS-CoV-2 infection and last at least 3 months to years. Despite representing a high burden for the Unified Health System (SUS), which has affected millions of Brazilians, it has received limited attention in Brazil. Prevalence studies to date have failed to include a broad representation of the population, and there has been insufficient exploration of the impact on people’s lives and the burden of and barriers to accessing health services. This article presents the research protocol for the quantitative component of a mixed methods project to produce evidence to inform SUS’s provision of care for long COVID. The protocol was designed to study long COVID in SUS patients hospitalised for COVID-19 in a large city in Southeast Brazil to capture symptoms and factors associated with the syndrome, effects on quality of life and employment, health needs, use of health services and barriers to accessing necessary healthcare.

Methods and analysis
An ambidirectional cohort study to capture data retrospectively and prospectively from adults previously discharged from SUS hospitals for COVID-19. The study involves up to two telephone surveys with the patients or proxies selected from a sampling plan for population estimates. Survey questions include baseline and follow-up data on demographic, socioeconomic, comorbidities, work status, health-related quality of life, vaccination status, long COVID symptoms, healthcare needs, use and barriers to access. Descriptive and appropriate multivariable analyses will be employed.

Ethics and dissemination
The project was approved by the Research Ethics Committees of participant institutions and by the Brazilian National Research Ethics Commission. All participants provided verbal consent. We plan to publish articles in scientific journals and multimedia resources for SUS professionals and the general population.

Background
Increasing evidence has emerged for traditional, complementary and integrative medicine (TCIM) to treat COVID-19 which requires systematic summaries of the net benefits of interventions against standard care and one another. The study aims to conduct a systematic review and network meta-analysis (NMA) regarding TCIM therapies for treating mild/moderate acute COVID-19, potentially informing the WHO guideline development and clinical decision-making.

Methods and analysis
We will search Embase, MEDLINE, Virtual Health Library on Traditional Complementary and Integrative Medicine, Cochrane Central Register of Controlled Trials, WHO’s International Clinical Trials Registry Platform with additional searches of Chinese and Korean literature sources for randomised controlled trials comparing TCIM with placebo, standard care, no treatment or with an alternate type of TCIM to treat COVID-19. We will limit the search dates from 2020 to 28 March 2024. Reviewers will, in duplicate, screen eligible articles, extract data and evaluate the risk of bias. We will conduct frequentist network meta-analyses for network comparisons and each outcome. We will assess the certainty of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach and classify interventions from most to least effective or harmful.

Ethics and dissemination
This NMA is based on the existing trials and data which is not subject to ethical approval. We will publish the NMA in a peer-reviewed journal. This may provide methodological reference and clinical evidence for TCIM on future epidemic-prone diseases.

Objectives
This study aims to identify the factors influencing vaccine hesitancy, willingness and its variation over time in order to inform more responsive strategies for increasing vaccination uptake. The specific objectives are: (1) to describe and compare levels of COVID-19 vaccine hesitancy among the general population in rural and urban settings in West Africa over time and (2) to identify factors associated with COVID-19 vaccination willingness and hesitancy among the general population across five West African countries over time.

Design
Following a baseline survey (Wave I), three serial cross-sectional surveys (Waves II-IV) were implemented.

Setting
The study was conducted in Burkina Faso, Guinea, Mali, Senegal and Sierra Leone from November 2021 to July 2022.

Participants
A total of 13 571 study participants were included in the study (n=4373, n=4593 and n=4605 for survey Waves II, III and IV, respectively). Inclusion criteria were being 18 years or older, living in the study area and willing to provide informed consent. A two-stage sampling strategy was used to select the sample from among the general population.

Primary and secondary outcomes
Primary outcomes were the variability of vaccine hesitancy over time and across the five West African countries. Secondary outcomes were factors associated with vaccine willingness.

Results
A small but steady increase in hesitancy to COVID-19-vaccination can be observed across countries, with an upward trend of vaccine hesitancy reported by 952 participants (33.9 %) in Wave II, 1055 (37.3%) in Wave III and 1089 (38.1%) in Wave IV. Among the countries included, Senegal shows the highest level of vaccine hesitancy (‘Definitely no’ and ‘Probably no’ ranging from 50.2% to 56.0% and 26.2 to 28.3%, respectively). At the same time, Senegal has the lowest vaccination coverage overall. Across all five countries and survey waves, the primary factor associated with vaccination willingness is fear of experiencing severe COVID-19 disease (Wave II: OR 0.42, 95% CI 0.34 to 0.51, Wave III: OR 0.48, 95% CI 0.40 to 0.59 and Wave IV: OR 0.54, 95% CI 0.44 to 0.66). Perceived improved financial status seems to influence willingness to get vaccinated negatively (OR 0.57, 95% CI 0.40 to 0.81) and unlike in Western, Educated, Industrialised, Rich and Democratic countries, men seem more reluctant to get vaccinated than women (OR 0.77, 95%, CI 0.65 to 0.93).

Conclusions
Our findings suggest that vaccine hesitancy should be monitored over time to inform communication strategies, which are responsive to changes in vaccination-related public sentiments. Additionally, a focus on social solidarity and the importance of women in vaccination advocacy can help improve COVID-19 vaccination coverage in West Africa.

Objectives
To explore experiences of physiotherapists working with adults living with Long COVID in Canada.

Design
Cross-sectional descriptive qualitative study involving online semi-structured interviews.

Participants
We recruited physiotherapists in Canada who self-identified as having clinically treated one or more adults living with Long COVID in the past year.

Data collection
Using an interview guide, we inquired about physiotherapists’ knowledge of Long COVID, assessment and treatment experiences, perspectives on physiotherapists’ roles, contextual and implementation factors influencing rehabilitative outcomes, and their recommendations for Long COVID rehabilitation. Interviews were audio-recorded, transcribed verbatim and analysed using a group-based thematic analytical approach. We administered a demographic questionnaire to describe sample characteristics.

Results
13 physiotherapists from five provinces participated; most were women (n=8; 62%) and practised in urban settings (n=11; 85%). Participants reported variable amounts of knowledge of existing guidelines and experiences working with adults living with Long COVID in the past year. Physiotherapists characterised their experiences working with adults living with Long COVID as a dynamic process involving: (1) a disruption to the profession (encountering a new patient population and pivoting to new models of care delivery), followed by (2) a cyclical process of learning curves and evolving roles of physiotherapists working with persons living with Long COVID (navigating uncertainty, keeping up with rapidly emerging evidence, trial and error, adapting mindset and rehabilitative approaches and growing prominence of roles as advocate and collaborator). Participants recommended the need for education and training, active and open-minded listening with patients, interdisciplinary models of care, and organisational- and system-level improvements to foster access to care.

Conclusions
Physiotherapists’ experiences involved a disruption to the profession followed by a dynamic process of learning curves and evolving roles in Long COVID rehabilitation. Not all participants demonstrated an in-depth understanding of existing Long COVID rehabilitation guidelines. Results may help inform physiotherapy education in Long COVID rehabilitation.
