Objectives
To examine trajectories of functional limitations, fatigue, health-related quality of life (HRQL) and societal costs of patients referred to long COVID clinics.

Design
A population-based longitudinal cohort study using real-time user data.

Setting
35 specialised long COVID clinics in the UK.

Participants
4087 adults diagnosed with long COVID in primary or secondary care deemed suitable for rehabilitation and registered in the Living With Covid Recovery (LWCR) programme between 4 August 2020 and 5 August 2022.

Main outcome measures
Generalised linear mixed models were fitted to estimate trajectories of functional limitations, using the Work and Social Adjustment Scale (WSAS); scores of ≥20 indicate moderately severe limitations. Other outcomes included fatigue using the Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-F) reversed score (scores of ≥22 indicate impairment), HRQL using the EQ-5D-5L, and long COVID-related societal costs, encompassing healthcare costs and productivity losses.

Results
The mean WSAS score at 6 months after registration in the LWCR was 19.1 (95% CI 18.6, 19.6), with 46% of the participants (95% CI 40.3%, 52.4%) reporting a WSAS score above 20 (moderately severe or worse impairment). The mean change in the WSAS score over the 6-month period was –0.86 (95% CI –1.32, –0.41). The mean reversed FACIT-F score at 6 months was 29.1 (95% CI 22.7, 35.5) compared with 32.0 (95% CI 31.7, 32.3) at baseline. The mean EQ-5D-5L score remained relatively constant between baseline (0.63, 95% CI 0.62, 0.64) and 6 months (0.64, 95% CI 0.59, 0.69). The monthly societal cost per patient related to long COVID at 6 months was £931, mostly driven by the costs associated with working days lost.

Conclusions
Individuals referred to long COVID clinics in the UK reported small improvements in functional limitations, fatigue, HRQL and ability to work within 6 months of registering in the LWCR programme.

Circulation, Volume 150, Issue Suppl_1, Page A4126987-A4126987, November 12, 2024. Background:COVID-19 infection has been associated with a broad range of clinical manifestations. There are very few reported cases of COVID-19 patients presenting with syncope as an initial symptom. We present an extraordinary case of recurrent neurocardiogenic syncope in a COVID-19 patient.Case:A 66-year-old male presented after experiencing two episodes of syncope. He denied any prodromal or anginal symptoms. His medications included propranolol 10 mg twice daily for essential tremors. He had no family history of unexplained syncope or sudden cardiac death. He was hemodynamically stable and had one episode of fever at 102°F. Telemetry recording showed vagal-mediated sinus arrest and pauses without escape. Blood work showed normal cell counts, electrolytes, thyroid-stimulating hormone, and erythrocyte sedimentation rate, with a slightly elevated C-reactive protein of 22.2 mg/L. He tested positive for COVID-19 and had negative Lyme and Ehrlichia serologies.Decision Making:Due to symptomatic long sinus pauses, propranolol was discontinued, and he received a temporary pacemaker set at 50 beats per minute (bpm). He had another syncopal episode while being paced at 50 bpm, suggesting a neurocardiogenic mechanism, so the pacing rate was increased to 70 bpm. An echocardiogram showed a normal ejection fraction without any significant valvular disease. The syncope was determined to be vasovagal due to autonomic dysfunction in the setting of COVID-19. After 72 hours without further syncope, the temporary pacemaker was removed, and he was discharged home with an implantable loop recorder (ILR). A one-month follow-up showed no syncope, and ILR interrogation showed no bradycardia or pauses.Conclusion:Neurocardiogenic syncope with prolonged asystole and sinus pauses is an uncommon presentation of COVID-19 infection. The clinical course of autonomic dysfunction following COVID-19 is not very clear, and monitoring with an ILR is reasonable before considering permanent pacemaker implantation.

Data surrounding the benefits of statins in patients with coronavirus disease 2019 (Covid-19) are conflicting. We sought to better understand the impact of statins in the context of Covid-19-related inflammation.Methods:We leveraged the International Study of Inflammation in Covid-19, a prospective multicenter cohort study of patients hospitalized specifically for Covid-19 between February 1, 2020 and October 30, 2022. Participants underwent systematic assessment of biomarkers of inflammation. We used logistic regression modeling and inverse probability-of-treatment weighting (IPTW) to examine the association between prior statin use and the composite outcome of in-hospital death, need for mechanical ventilation, and need for renal replacement therapy.Results:A total of 4,464 patients were included in the study, of whom 1,364 (27.5%) were taking a statin prior to admission. There were 1,061 primary outcome events, including 540 deaths, 854 mechanical ventilation and 313 renal replacement therapy. Amongst biomarkers of inflammation, statin use was associated solely with lower levels of soluble urokinase plasminogen activator receptor (suPAR) after adjusting for known confounders. In multivariable logistic regression analysis, statin use was associated with lower odds of the composite outcome (adjusted odds ratio (aOR) 0.63, 95%CI[0.53-0.76]) compared to patients not on statins. Findings were consistent with IPTW (aOR 0.92, 95%CI [0.89- 0.95]). The proportion of the effect of statin on the primary outcome mediated by suPAR was estimated at 31.5%.Conclusion:Prior statin use is associated with improved outcomes and lower inflammation as measured by suPAR levels in patients hospitalized for Covid-19.

Introduction:Low physical activity (PA) has been identified as a risk factor for development of atrial fibrillation (AF). However, the effect of changes in PA on directly recorded AF burden has not been well studied. The COVID-19 pandemic offered an opportunity to observe whether changes in activity were correlated with changes in AF burden. To determine if reduced PA is associated with higher AF burden, we assessed daily PA and AF burden data from patients with cardiac implantable electronic devices (CIEDs) enrolled in a prospective clinical trial, Targeting Risk Interventions and Metformin for Atrial Fibrillation (TRIM-AF, NCT03603912).Methods:Daily AF burden and activity were determined from implantable cardiac devices with atrial leads. The pandemic lockdown period was analyzed for up to 1 year. Pre-pandemic periods were matched by month to pandemic periods. To test the potential confounding of aging, pre-pre-pandemic periods were matched by month to pre-pandemic periods. To reduce the confounding of study interventions, matched periods were taken on one side of the study enrollment date. For PA and AF burden, Gaussian linear mixed models and a Bayesian mixed effect model were fitted and adjusted for age, sex, and device manufacturers. A Gaussian model was used to correlate daily activity minutes and AF%. Time splines were added to adjust for non-linear time effects. Outcomes are reported as mean activity minutes and daily AF%.Results:Comparing Pandemic vs. Pre-periods (N=82 periods; 55 male, 27 female), daily activity minutes decreased by a mean of 13.16±1.06 minutes/day, and daily AF burden increased by 16% [5%-26%]. Comparing Pre vs. Pre-Pre-Pandemic periods (N=60 periods; 41 male, 19 female), mean activity decreased by 2.28±1.13 mins/day, and AF burden increased by 57% [50%-64%]. A significant negative correlation between activity and AF burden was demonstrated (coefficient -2.0, 95% CI -2.4, -1.6). A decrease in 2.0 activity minutes was associated with a 10% increase in AF burden.Conclusions:This natural history analysis of PA and AF burden demonstrated decreases in activity and increases in AF burden with time and the pandemic. Activity and AF burden were significantly negatively correlated.

Circulation, Volume 150, Issue Suppl_1, Page A4143488-A4143488, November 12, 2024. Background:Patients with acute decompensated heart failure (ADHF) often require admission to the Cardiac Care Unit (CCU). Clinical examination alone may be inadequate for management, leading to suboptimal diuretic regimens and prolonged hospital stays. The use of Point-of-care ultrasound (POCUS) to evaluate the lungs for pulmonary edema and inferior vena cava (IVC) for size and collapsibility can enhance volume status evaluation.Aim:Reduce the average duration of IV diuresis by 20% among patients admitted to the CCU for ADHF in 1 yearMethods:An algorithm for POCUS guided diuretic regimen escalation was implemented across three Plan-Do-Study-Act (PDSA) cycles. Patients who were intubated, on dialysis, or with isolated RV failure were excluded. PDSA-1 introduced the algorithm and provided training to a team of 5 residents. PDSA-2 included weekly reminders and recruitment of 14 residents to increase buy-in. PDSA-3 focused on incorporating POCUS assessments into nighttime care to facilitate early morning decision-making.Results:Process Measure: Quarterly compliance rates using the number of POCUS orders that were completed- Baseline (0%, n=23), PDSA-1 (0%, n=35), PDSA-2 (19%, n=15), PDSA-3 (31%, n=46).Outcome Measure: The average duration of IV diuresis progressively decreased through the year: Baseline (5 days), PDSA-1 (5.3 days), PDSA-2 (4.4 days), PDSA-3 (3.5 days). There was an increase of 6% in PDSA-1 compared to baseline, but PDSA-2 and 3 showed a progressive reduction of 12% and 30% respectively.Balancing Measure: The mean potassium supplementation showed variation throughout the year: Baseline (63.3 mg), PDSA-1 (141 mg), PDSA-2 (151.7 mg), PDSA-3 (75.7 mg), reflecting no significant negative impact from the intervention.Equity Lens: The duration of IV diuresis, which at baseline ranged from 3 to 8 days across different races, standardized to approximately 5 days for all races by PDSA-3.Conclusion:We progressively reduced the duration of IV diuresis using POCUS-guided lung and IVC assessments with a structured diuretic regimen. This demonstrated improved patient care from early decongestion and symptomatic relief. Additionally, we demonstrate that POCUS plays a crucial role in promoting health equity by providing an objective assessment of volume status across diverse racial groups. This integration promises optimized heart failure management and potential cost reductions from reduced length of stay, highlighting the value of POCUS in clinical practice.

Circulation, Volume 150, Issue Suppl_1, Page A4145229-A4145229, November 12, 2024. Background:Stress-induced cardiomyopathy (CM) is a form of acute transient left ventricular dysfunction triggered by underlying physiological stress which often leads to increased morbidity and mortality. Coronavirus disease 2019 (COVID-19) is thought to cause stress-induced CM due to overwhelming systemic inflammation. There is paucity of data regarding the impact of COVID-19 on in-hospital outcomes of patients with stress-induced CM. The purpose of this study is to investigate in-hospital outcomes, including mortality and cardiogenic shock, of patients with concomitant COVID-19 and stress-induced CM.Methods:We queried the 2020 USA National Inpatient Sample (NIS) Database in conducting this retrospective cohort study. We identified hospitalized adult patients ≥ 18 years old with stress-induced CM and concomitant COVID-19 using ICD-10 CM codes. We used a survey multivariable logistic and linear regression analysis to calculate adjusted odds ratios (aORs) for outcomes of interest. A p value of

Circulation, Volume 150, Issue Suppl_1, Page A4125636-A4125636, November 12, 2024. Background:Postural orthostatic tachycardia syndrome (POTS) is a prevalent cardiovascular disorder after COVID-19 infection. Although POTS is characterized by the presence of sinus tachycardia, other hemodynamic disturbances including blood pressure (BP) regulation, remain largely unexplored.Aims:We investigated BP changes using 24-hour ambulatory-BP-monitoring in patients with new-onset POTS after COVID-19 compared with pre-pandemic healthy controls.Methods:We performed a case-control study in 100 verified COVID-19 patients with new-onset POTS (mean age 40.0±12.9 years, 85% women) diagnosed by positive head-up tilt-testing versus 100 healthy controls (mean age 45.0±14.6 years, 70% women) from a population-based cohort with negative active standing test, no history of syncope, orthostatic intolerance, or endocrine disease. We analyzed 24-hour Systolic BP (SBP) and hypotensive SBP episodes (

Circulation, Volume 150, Issue Suppl_1, Page A4145299-A4145299, November 12, 2024. Background:COVID-19 can present with a wide spectrum of clinical manifestations ranging from asymptomatic to life-threatening. It is often thought of as a primarily pulmonary infection and different systemic presentations are sometimes overlooked. We present a case of COVID-19 induced myocarditis leading to hemodynamic instability and end-organ dysfunction.Case presentation:A 77-year-old male with a history of CKD, paroxysmal atrial fibrillation, and COPD was transferred to our hospital for a higher level of care due to worsening cardiogenic shock. He was cold and wet (Forrester class IV) with a High Sensitivity troponin of 331 and a BNP level of 21,503. EKG showed atrial fibrillation with RVR but no evidence of acute ischemic changes. A TTE was done which revealed an EF of 30-35% and diffuse hypokinesis with regional variation, a significant reduction from an EF of 50-55% just 4 weeks prior. The patient exhibited end-organ dysfunction, as evidenced by deranged liver function tests and a rise in creatinine from a baseline of 2 to 4.6, indicating congestive hepatopathy and cardiorenal syndrome respectively. The patient’s hemodynamics necessitated milrinone and norepinephrine infusions and efforts to wean them off were unsuccessful due to repeated failed fluid bolus challenges. Considering the patient’s clinical picture, there was a strong suspicion of viral-induced cardiomyopathy, and a COVID-19 infection was confirmed by PCR testing; his last COVID-19 booster dose was in 2021. The patient was promptly started on remdesivir and IV steroids. Unfortunately, the patient’s condition continued to deteriorate, and he succumbed to his illness.Discussion:A myriad of cardiovascular manifestations have been implicated with COVID-19, including ACS, myocarditis, and heart failure. Although the exact underlying mechanisms for each of these conditions are unclear, a complex interplay between direct viral injury, systemic inflammation, and cytokine storm has been hypothesized. Our case illustrates the quick progression of heart failure into cardiogenic shock requiring pressor support, with subsequent rapid decompensation rendering CMR, cardiac catheterization, and biopsy timely impractical. It serves as a reminder to explore COVID-19 as a potential cause of biventricular failure in individuals with no evident reason and rapid clinical deterioration, particularly as early initiation of antiviral therapy could improve prognoses.

Circulation, Volume 150, Issue Suppl_1, Page A4140179-A4140179, November 12, 2024. Background:COVID-19 has led to significant global morbidity and mortality. Its impact on patients with hypertrophic cardiomyopathy (HCM) remains unclear.Aim:To evaluate the impact of COVID-19 infection on the readmission rate and associated outcomes in patients with HCM.Methods:In a retrospective study using the 2020 National Readmission Database, we collected data on patients with HCM who were admitted with the principal diagnosis of COVID-19. The primary outcome was the all-cause 30-day readmission rate. Secondary outcomes were common causes of readmission, in-hospital mortality, and resource utilization.Results:In 2020, a total of 1503 patients with HCM (mean age 67 years, 49% female) were hospitalized for COVID-19. Among them, 1216 (80.9%) were discharged alive and 180 (14.8%) were readmitted within 30 days. In-hospital mortality for readmissions remained relatively unchanged compared with index admissions (15.4% vs 19.0%, P=.34; Table 1). The most common cause of readmission was COVID-19 infection (38%), followed by other infections (11%) and acute kidney injury (4%). The most common cardiac cause for readmission was paroxysmal atrial fibrillation (2%). The mean length of stay for readmissions was relatively similar to the index admission (7.8 vs 9.9 days, P=.43). The mean hospital charge associated with readmission was $84,976 (total hospital charges were $15.2 million). The mean hospital cost associated with readmissions was $24,603 (total hospital costs were $4.4 million). A higher Charlson comorbidity index score was the main independent predictor of higher readmission rates.Conclusions:This study highlights the significant burden of COVID-19 on patients with HCM. Despite efforts to reduce readmission rates, a considerable percentage of patients experienced readmission within 30 days, largely attributed to COVID-19 infection. Close follow-up after discharge could prevent such readmission and the associated high mortality rates.

Circulation, Volume 150, Issue Suppl_1, Page A4145096-A4145096, November 12, 2024. Introduction:Postural orthostatic tachycardia syndrome (POTS) and Inappropriate sinus tachycardia (IST) are common manifestations of cardiovascular dysautonomia (CVAD) in patients with post-COVID-19 syndrome. Studies regarding differences between post-COVID-19 POTS and post-COVID-19 IST have been sparse and based on small patient series.Aims:To examine clinical differences between POTS and IST in patients with post-COVID-19 syndrome.Methods:A cross-sectional observational study based on a dataset of patients diagnosed with post-COVID-19 syndrome and POTS/IST, at Karolinska University Hospital, Stockholm in 2020-2023, was performed. Data was retrieved using patients’ medical records. ANOVA, chi-square tests and Fisher’s exact tests were used for analysis.Results:A total of 200 patients diagnosed with post-COVID POTS/IST (ICD-10 codes, I.498 + U.099) were included (female, 85%) and divided into a POTS-group (n=110) and IST-group (n=90). Sixty-one patients (31%) met the diagnostic criteria of both and were included in the IST-group. The mean ages were 38 years for the POTS-group and 42 years for the IST-group (p=0.027). Hypertension was more common within the IST-group (p

Circulation, Volume 150, Issue Suppl_1, Page A4140218-A4140218, November 12, 2024. Background:Prior data indicated a reduction in mortality among STEMI (ST-elevation myocardial infarction) patients with COVID-19 from 2020 to 2021 in the United States.Objective:To describe national trends and determinants of outcomes among STEMI patients with COVID-19 from 2020-2021.Methods:A retrospective cohort study was conducted using the 2020-2021 Nationwide Inpatient Sample of adults diagnosed with STEMI and COVID-19, assessing in-hospital mortality and the use of percutaneous coronary intervention (PCI), mechanical ventilation, and mechanical circulatory support (MCS).Results:The study included 6,195 STEMI patients with COVID-19 and revealed stable mortality (18% in 2020 to 21% in 2021,p=0.06). Demographic shifts occurred, with White patients increasing from 52% in 2020 to 66% in 2021 (p

Circulation, Volume 150, Issue Suppl_1, Page A4141333-A4141333, November 12, 2024. Background:COVID-19 is a multiorgan disease characterized by a prothrombotic state and increased risk of venous thromboembolism (VTE), especially in hospitalized patients. Although prior studies have attempted to identify predictors of VTE, restricted sample size and use of administrative claims data have limited such analyses. We conducted a multivariable analysis to identify predictors of VTE in hospitalized patients with COVID-19 in a multicenter patient-level registry.Methods:We utilized data from the CORONA-VTE Network, a US multicenter registry of 10,420 adult (≥18 years) patients with PCR-confirmed COVID-19 of whom 3,844 were hospitalized. The primary outcome was time-to-first-event for a composite of adjudicated pulmonary embolism and deep vein thrombosis (e.g. lower extremity, mesenteric, gonadal vein, etc.) during 90-day follow-up. The candidate variables were selected by a priori clinical consensus. The variables with ≥20% missing data were excluded, whereas those with missing data
