Echocardiographic features of COVID-19 patients without significant baseline cardiovascular disease.

Objective. To assess the relationship between the severity of COVID-19 in patients without significant baseline cardiovascular pathology and various echocardiographic parameters of myocardial dysfunction. Material and methods. 46 patients with COVID-19 were included in our study: 33 patients of moderate severity and 13 - with severe disease. On days 1 and 9 upon admission, all patients underwent an echocardiographic study with standard assessment of the both ventricles function, as well as an assessment of their global longitudinal strain (GLS). Comparison of the studied parameters was carried out both between groups of patients and within each group in dynamics. Results. On day 1patients in the severe group had higher values of the systolic gradient on the tricuspid valve (22.0 [21.0;26.0] vs 30.0 [24.0;34.5] mm Hg, p = 0.02), systolic excursion of the plane of the tricuspid ring (2.3 [2.1;2.4] vs 2.0 [1.9;2.2] mm, p = 0.016), E/e' ratio (9.5 [7.7;8.9] vs 7.5 [6.8;9.3], p = 0.03). At day 9 among patients in the severe group, there was a decrease in end-diastolic (111.0 [100.0;120.0] vs 100.0 [89.0;105.0] ml, p = 0.03) and of end-systolic (35.5 [32.0;41, 2] vs 28.0 [25.0;31.8] ml, p < 0.01) volumes of the left ventricle. There was a decrease in GLS of the both ventricles compared to general accepted values. In dynamics, there was an increase in the GLS of the right ventricle in both groups, but it was more pronounced among severe group of patients (day 1 -18.5 [-15.2;-21.1] vs -20.2 [-15.8.1;-21.1] %, p = 0.03). The troponin levels were in the normal range. Conclusion. In COVID-19 patients without significant baseline cardiovascular pathology, there is a transient decrease in longitudinal strain of both ventricles, even in the absence of clinical and laboratory signs of acute myocardial injury.Copyright © Creative Cardiology 2021.

Acute or chronic? Failing left ventricle in a 34 year old

Submission content Introduction: An unusual case of a very young patient without previously known cardiac disease presenting with severe left ventricular failure, detected by a point of care echocardiogram. Main Body: A 34 year old previously well man was brought to hospital after seeing his general practitioner with one month of progressive shortness of breath on exertion. This began around the time the patient received his second covid-19 vaccination. He was sleeping in a chair as he was unable to lie flat. Abnormal observations led the GP to call an ambulance. In the emergency department, the patient required oxygen 5L/min to maintain SpO2 >94%, but he was not in respiratory distress at rest. Blood pressure was 92/53mmHg, mean 67mmHg. Point of care testing for COVID-19 was negative. He was alert, with warm peripheries. Lactate was 1.0mmol/L and he was producing more than 0.5ml/kg/hr of urine. There was no ankle swelling. ECG showed sinus tachycardia. He underwent CT pulmonary angiography which demonstrated no pulmonary embolus, but there was bilateral pulmonary edema. Troponin was 17ng/l, BNP was 2700pg/ml. Furosemide 40mg was given intravenously by the general medical team. Critical care outreach asked for an urgent intensivist review given the highly unusual diagnosis of pulmonary edema in a man of this age. An immediate FUSIC Heart scan identified a dilated left ventricle with end diastolic diameter 7cm and severe global systolic impairment. The right ventricle was not severely impaired, with TAPSE 18mm. There was no significant pericardial effusion. Multiple B lines and trace pulmonary effusions were identified at the lung bases. The patient was urgently discussed with the regional cardiac unit in case of further deterioration, basic images were shared via a cloud system. A potential diagnosis of vaccination-associated myocarditis was considered,1 but in view of the low troponin, the presentation was felt most likely to represent decompensated chronic dilated cardiomyopathy. The patient disclosed a family history of early cardiac death in males. Aggressive diuresis was commenced. The patient was admitted to a monitored bed given the potential risk of arrhythmia or further haemodynamic deterioration. Advice was given that in the event of worsening hypotension, fluids should not be administered but the cardiac centre should be contacted immediately. Formal echocardiography confirmed the POCUS findings, with ejection fraction <35%. He was initiated on ACE inhibitors and beta adrenergic blockade. His symptoms improved and he was able to return home and to work, and is currently undergoing further investigations to establish the etiology of his condition. Conclusion(s): Early echocardiography provided early evidence of a cardiac cause for the patient's presentation and highlighted the severity of the underlying pathology. This directed early aggressive diuresis and safety-netting by virtue of discussion with a tertiary cardiac centre whilst it was established whether this was an acute or decompensated chronic pathology. Ultrasound findings: PLAX, PSAX and A4Ch views demonstrating a severely dilated (7cm end diastolic diameter) left ventricle with global severe systolic impairment.

The association between the elevated serum levels of cardiac Trop I and mortality in patients with and without pre-existing CAD in COVID-19 patients: A retrospective observational study

Background: COVID-19 has appeared as a pandemic and public health issue at a universal level. First documented as a respiratory disease, COVID-19 has been found to interrelate with and disturb the cardiovascular system causing myocardial injury and also cardiac dysfunction. Initial documentation of cardiac pathology can play a substantial role in dropping the death rate. This study emphasizes on the relationship between the serum levels of cardiac Trop I and prognosis in patients with and without pre-existing CAD in COVID-19 patients. Aims and Objectives: The first objective was to explore the association among the serum levels of cardiac Trop I and bad prognosis in patients with antiquity of CAD and without CAD. The secondary objective was to explore and understand whether increased Trop I is an appreciated prognostic indicator for COVID-19 patient antagonistic prognosis. Material(s) and Method(s): This was conducted as a retrospective observational study in which a whole of 45 patients admitted in COVID Hospital of Malabar Medical College and Research Center category C were studied. The medical record of the patients whose COVID-19 confirmation done by combined conclusions of reverse transcription PCR, symptoms, and chest X-ray was studies by the team. Result(s): Mean age of the study participants was 59.3 +/- 13.7. Every study participants had elevated Trop I levels with a median Trop I in study subjects being 397.9. There was a statistically significant elevation in Trop I levels in patients with CAD linked with non-CAD patients with a median IQR of 641.6 and P = 0.003 and there was a significant increase in Trop I levels in patients who expired related to patients who got discharged with a median IQR of 587.3 and P = 0.003. Conclusion(s): From this study, we accomplish that rise in cardiac troponin-I level is connected with elevated mortality in patients with COVID-19. Hence, it can be used as significant biomarker of disease evolution, hospitalization, and worse prognosis in COVID-19 patients.Copyright © 2023, Mr Bhawani Singh. All rights reserved.

Bilateral Spontaneous Pneumothorax in a Child with Multisystem Inflammatory Syndrome Associated with COVID-19

Introduction: Spontaneous pneumothorax is a rare complication of coronavirus disease 2019 (COVID-19), primarily reported in adults. Pediatric cases with bilateral pneumothorax are much less reported. Case Presentation: We presented the case of a five-year-old previously healthy boy who developed persistent fever, abdominal pain, generalized maculopapular rash, and dyspnea before admission. His chest computed tomography (CT) showed a viral involvement pattern of pneumonia suggestive of COVID-19. Subsequently, he was confirmed with multisystem inflammatory syndrome in children (MIS-C). While he responded well to the therapies, on the fifth day of admission, he developed respiratory distress again. A chest roentgenogram showed bilateral spontaneous pneumothorax. Bilateral chest tubes were inserted, and his condition improved sig-nificantly after five days of admission to the intensive care unit. Two weeks later, he was discharged in good condition. Conclusion(s): Children with MIS-C associated with COVID-19 may develop primary spontaneous pneumothorax. Owing to the clinical picture overlapping with MIS-C associated with COVID-19, the timely diagnosis of pneumothorax may be challenging in such patients.Copyright © 2022, Author(s).

Direct bilirubin and the neutrophil-to-monocyte ratio timely predict intensive care unit admission in patients with severe acute respiratory syndrome coronavirus-2 infection (COVID-19)

Objective: Intensive care units (ICUs) collapsed under the global wave of coronavirus disease 2019 (COVID-19). Thus, we designed a clinical decision-making model that can help predict at hospital admission what patients with COVID-19 are at higher risk of requiring critical care. Method(s): This was a cross-sectional study in 119 patients that met hospitalization criteria for COVID-19 including less than 30 breaths per minute, peripheral oxygen saturation < 93%, and/or >= 50% lung involvement on imaging. Depending on the need for critical care, patients were retrospectively assigned to ICU and non-ICU groups. Demographic, clinical, and laboratory parameters were collected at admission and analyzed by classification and regression tree (CRT). Result(s): Forty-five patients were admitted to ICU and 80% of them were men older than 57.13 +/- 12.80 years on average. The leading comorbidity in ICU patients was hypertension. The CRT revealed that direct bilirubin (DB) > 0.315 mg/dl together with the neutrophil-to-monocyte ratio (NMR) > 15.90 predicted up to correctly in 92% of the patients the requirement of intensive care management, with sensitivity of 93.2%. Preexisting comorbidities did not influence on the tree growing. Conclusion(s): At hospital admission, DB and NMR can help identify nine in 10 patients with COVID-19 at higher risk of ICU admission.Copyright © 2022 Sociedad Medica del Hospital General de Mexico.

Cardiac manifestations of post-COVID syndrome in children and adolescents.

The aim of the research. To study the features of cardiovascular system disorders in post-covid syndrome (PCS) in children and adolescents after a mild form of coronavirus infection (COVID-19). Material and methods. From 260 children and adolescents after a mild form of COVID-19, a total of 30 patients aged 7-17 years with cardiac manifestations of PCS were selected. Therewith, 32 patients with an uncomplicated form of the disease were selected to form a comparison group. In 3 and 6 months after disease onset, a comprehensive examination of patients was performed with a questionnaire on the subjective scale for MFI-20 assessment asthenia (Multidimensional Fatigue Inventory-20), electrocardiography (ECG), echocardiography;daily monitoring of ECG and blood pressure. The biochemical blood test included assay of creatine phosphokinase-MB (CPK-MB), troponin I and lactate dehydrogenase (LDH). Results. The incidence of PCS with cardiac manifestations amounted to 11.5 %. After 3 months from the disease onset, complaints of pain and discomfort in the chest, palpitations, fatigue, and poor exercise tolerance persisted. Asthenic syndrome was diagnosed in 70 % of patients. The "general asthenia" indicator totalled14 [12;16] points (p<0.001) and was associated with the age of patients (r=+0.5;p<0.05). Arrhythmic syndrome and conduction disorders were detected in 67% of children. Labile arterial hypertension and hypotension occurred in 23 % of the adolescents. The increase in CPK-MB remained in 17% of the children, LDH - in 10%. In the sixth month after the onset of the disease, there were no significant differences in the results of the examination in the observation groups. However, a decrease in the level of resistance within 6 months was recorded in 43.3% of the schoolchildren with PCS (p<0.001). Conclusion. The data obtained indicate the need for early verification of cardiopathies in children with COVID-19, determination of a set of therapeutic and rehabilitation measures as well as ECG monitoring.Copyright © 2022, Krasnoyarsk State Medical University.

Interpreting High Sensitivity Troponins in Various Acute Clinical Settings - Increased Significance to the Present.Day Cardiologist

High-sensitivity cardiac troponins expedite the evaluation of patients with chest pain in the emergency department. The utility of troponins extends beyond the acute coronary syndromes to accurate the diagnosis of myocardial injury. Troponins are best friends for physicians;however, they are a double-edged sword if not interpreted appropriately. Misdiagnosis is harmful with regard to patient outcomes. The present review focuses on the recent updates in the understanding and interpretation of high-sensitivity troponins in various acute clinical settings. Common mistakes and gray zones in the interpretation of troponins, the concept of myocardial injury versus infarction, newer entities like myocardial infarction (MI) with Nonobstructive Coronary Arteries, recent controversies over the definition of periprocedural MI, complementary role of imaging in the diagnosis of myocardial injury and the role of troponins in the current COVID-19 pandemic are discussed.Copyright © 2022 Saudi Center for Organ Transplantation.

The impact of deprivation on Respiratory Support Unit outcomes in COVID-19 patients, and highlights from wave 2 data in Portsmouth

Background: The second wave of the COVID-19 pandemic caused significant demand for beds capable of delivering enhanced respiratory support. NHS England recommended the use of CPAP for patients with COVID-19 respiratory failure, a treatment which can be offered outside of a critical care facility, and on a Respiratory High Care/ Support Unit (RSU). The enhancement of Portsmouth's RSU provided CPAP and NIV for patients with COVID-19 respiratory failure. With our intensive care facilities at 300% their normal capacity, this greatly alleviated bed pressures on critical care. Varied levels of deprivation exist in Portsmouth's dense population. Deprivation has an impact on overall health, however the effect of postcode on outcomes for people going onto support for COVID-19 respiratory failure, is unknown. Method(s): Retrospective cohort analysis of consecutive patients admitted to Respiratory Support Unit during the second wave of the COVID-19 pandemic, from 02/11/2020 to 31/01/2021. 227 patients were included in the study with 8 removed due to incomplete data, all of the patients received respiratory support in the form of CPAP or NIV. We collected multivariate data including biochemical markers, demographics, oxygenation status, co-morbidities and outcomes. Outcomes measured were: 1) Death in RSU, 2) Discharge from RSU or 3) Intubation and Ventilation. To measure deprivation, we linked a persons postcode to an area called an LSOA (Lower-layer Super Output Area). These are small areas of similar population size, each of which has a deprivation score (ie. top 10%, to the lowest 10% areas of deprivation in the UK). This is measured using an 'index of multiple deprivation'. An individual's outcome from the RSU was then analysed in relation to the deprivation score allocated to their postcode. Result(s): We observed a significant number of patients discharged from RSU, without needing invasive mechanical ventilation. 80/219 were discharged directly. 45/219 died in RSU, and 94 were eventually admitted to ITU. The average stay on CPAP or NIV before needing admission to ITU was 3 days. Some biochemical markers which stood out in relation to the outcomes described were as follows: average LDH, D-dimer and Troponin levels were higher in those who were admitted to intensive care. In patients who died, the PCT was significantly higher on average when compared to the other two groups. In the group who were discharged, mean lymphocyte count was >1, in the other two groups this was <1. From our observations in Portsmouth, there is a negative correlation between deprivation and lower aged individuals admitted for COVID-19 related respiratory support. Overall, we also saw disproportionate representation of those from the most deprived 50% of the UK in our respiratory support unit. Conclusion(s): CPAP and NIV can effectively be used in an RSU during a spike of COVID-19, to safely minimise demand on critical care services. Deprivation may have an impact on outcomes in patients needing respiratory support related to COVID-19. Deprivation levels may help predict risk of needing enhanced respiratory support in certain age groups. Multiple biochemical markers may be of prognostic value in COVID-19.

Cannabis-Induced Catatonia in a 15-Year-Old Male: A Case Report

Introduction: Catatonia is a syndrome of primarily psychomotor disturbances most common in psychiatric mood disorders but that also rarely has been described in association with cannabis use. Case Presentation: A 15-year-old White male presented with left leg weakness, altered mental status, and chest pain, which then progressed to global weakness, minimal speech, and a fixed gaze. After ruling out organic causes of his symptoms, cannabis-induced catatonia was suspected, and the patient responded immediately and completely to lorazepam administration. Discussion(s): Cannabis-induced catatonia has been described in several case reports worldwide, with a wide range and duration of symptoms reported. There is little known about the risk factors, treatment, and prognosis of cannabis-induced catatonia. Conclusion(s): This report emphasizes the importance of clinicians maintaining a high index of suspicion to accurately diagnose and treat cannabis-induced neuropsychiatric conditions, which is especially important as the use of high-potency cannabis products in young people increases.Copyright © 2023, State Medical Society of Wisconsin.

ECMO in acute fulminant myocarditis in pediatrics

Objectives: To describe our experience in ECMO for acute myocarditis Methods: Descriptive, retrospective study (2018-2022) of a cohort of 8 patients < 16 years with acute myocarditis who were assisted on ECMO. Result(s): 8 patients were collected, (6 females), with a mean age 7;8 years [range 0;1-13;8]. In 7/8, the reason for cannulation was hemodynamic instability refractory to medical treatment, with a mean inotropic score of 70 [range 10-122]. Sixty-two percent presented cardiorespiratory arrest prior to cannulation and 2 of them needed ECRP. The mean precannulation troponin level was 1498 ng/ml [range 89-6212]. Primary transport was performed in 4 patients. ECMO was peripheral veno-arterial in 100%, jugulo-carotid in 2/8 and femoro-femoral in 6/8. All patients underwent atrioseptostomy. They received treatment with levosimendan, immunoglobulins, corticoids and carnitine. In 4 acute infectious etiology was confirmed (parvovirus, influenza and SARSCoV2), another one was due to PIMS-TS and in 3 no etiology was found. Six patients underwent myocardial biopsy and 5 of them showed inflammatory infiltrates. The mean time on ECMO was 8 days [range 3-14], 2 of them requiring 2 ECMO courses. The mean length of PICU stay was 21 days [range 10-50]. Two were transferred to a heart transplant center. The main complications were arterial hypertension (88%), bleeding (63%), neurological (50%), arrhythmias (38%), coagulopathy (38%) and infectious (38%). One patient required renal replacement therapy. 1 patient died, 2 had moderate neurological sequels. Conclusion(s): ECMO is a therapeutic option in patients with fulminant myocarditis refractory to medical treatment and may help improve their prognosis.

Metabolic risks and prognosis of COVID-19: are dietary patterns important? (Special Issue: The relationship between nutrition and COVID-19.)

Purpose: This study aims to identify the dietary patterns of two groups of subjects (with and without COVID-19), and to assess the relationship of findings with the prognosis of COVID-19 and metabolic risk parameters. Design/methodology/approach: This study included 100 individuals in the age range of 19-65 years. The medical history, and data on biochemical, hematological and inflammatory indicators were retrieved from the files. A questionnaire for the 24-h food record and the food intake frequency was administered in face-to-face interviews, and dietary patterns of subjects were assessed. Findings: In individuals with COVID-19, the hip circumference, the waist-hip ratio and the body fat percentage were significantly higher (p < 0.05), and the muscle mass percentage was significantly lower (p < 0.05). Mediterranean diet adherence screener (MEDAS), dietary approaches to stop hypertension (DASH) and healthy eating index-2015 (HEI-2015) scores were low in the two groups. A linear correlation of DASH scores was found with the muscle mass percentage (p = 0.046) and a significant inverse correlation of with the body fat percentage (p = 0.006). HEI-2015 scores were significantly and negatively correlated with body weight, body mass index, waist circumference, hip circumference and neck circumference (p < 0.05). Every one-unit increase in MEDAS, DASH and HEI-2015 scores caused reductions in C-reactive protein levels at different magnitudes. Troponin-I was significantly and negatively correlated with fruit intake (p = 0.044), a component of a Mediterranean diet and with HEI-2015 total scores (p = 0.032). Research limitations/implications: The limitation of this study includes the small sample size and the lack of dietary interventions. Another limitation is the use of the food recall method for the assessment of dietary patterns. This way assessments were performed based on participants' memory and statements. Practical implications: Following a healthy diet pattern can help reduce the metabolic risks of COVID-19 disease. Originality/value: Despite these limitations, this study is valuable because, to the best of the authors' knowledge, it is the first study demonstrating the association of dietary patterns with disease prognosis and metabolic risks concerning COVID-19. This study suggests that dietary patterns during the COVID-19 process may be associated with several metabolic risks and inflammatory biomarkers.

The impact of daily troponin I and D-dimer serum levels on mortality in COVID-19 pneumonia patients.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an infection resulting in very high morbidity and mortality rates globally. Limited data are available on the cardiovascular manifestations in these patients. The aim of this study was to analyse the daily troponin I and D-dimer levels and their impact on the need for intensive care and on mortality rates of COVID-19-infected patients. METHODS: Two-hundred and five patients who were hospitalised between 20 March and 5 May 2020, with a diagnosis of moderate-to-severe COVID-19 pneumonia, were analysed retrospectively. Serum troponin I and D-dimer levels were recorded for at least 10 days after admission. RESULTS: The average age was higher in the group of patients who died compared to the group who were discharged (67.79 ± 14.9 vs 56.87 ± 18.15 years, respectively, p < 0.001). The presence of hypertension, diabetes mellitus, previous coronary bypass surgery, heart failure, chronic renal failure and chronic obstructive pulmonary disease statistically significantly affected mortality rates (p = 0.003, 0.004, 0.045, 0.02, 0.003, 0.007, respectively). The first 10 days of measurements of troponin I and D-dimer were associated with intensive care requirements and mortality (p < 0.001). Both troponin I and D-dimer were higher in the group who died compared to the patients requiring intensive care. Troponin I values of ≥ 16.05 pg/ml on the seventh day were related to the need for intensive care [area under the curve (AUC) 0.896, sensitivity 78.6%, specificity 78.3%, p < 0.001). Troponin I values ≥ 30.25 pg/ml on the ninth day were related to mortality (AUC 0.920, sensitivity 89.5%, specificity 89.3%, p < 0.001). D-dimer values ≥ 878 hg/ml on the second day were associated with intensive care need (AUC 0.896, sensitivity 78.6%, specificity 78.3%, p < 0.001). D-dimer values ≥ 1 106 hg/ml on the 10th day were associated with mortality (AUC 0.817, sensitivity 68.4%, specificity 65.2%, p < 0.001). It was observed that hospitalisation periods ≥ 9.5 days were associated with mortality (AUC 0.738, sensitivity 68.4%, specificity 65.9%, p < 0.001). CONCLUSIONS: We showed that hospitalisations ≥ 9.5 days in duration were related to increased mortality rates. Troponin I and D-dimer follow-up values in the serum were more effective than other inflammatory markers in predicting mortality and the need for intensive care. A high troponin I value should alert the clinician in terms of clinical deterioration.

New Insights on the Mechanisms of Myocardial Injury in Hypertensive Patients With COVID-19.

PURPOSE: Myocardial injury is common in hypertensive patients with 2019 coronavirus disease (COVID-19). Immune dysregulation could be associated to cardiac injury in these patients, but the underlying mechanism has not been fully elucidated. METHODS: All patients were selected prospectively from a multicenter registry of adults hospitalized with confirmed COVID-19. Cases had hypertension and myocardial injury, defined by troponin levels above the 99th percentile upper reference limit, and controls were hypertensive patients with no myocardial injury. Biomarkers and immune cell subsets were quantified and compared between the two groups. A multiple logistic regression model was used to analyze the associations of clinical and immune variables with myocardial injury. RESULTS: The sample comprised 193 patients divided into two groups: 47 cases and 146 controls. Relative to controls, cases had lower total lymphocyte count, percentage of T lymphocytes, CD8+CD38+ mean fluorescence intensity (MFI), and percentage of CD8+ human leukocyte antigen DR isotope (HLA-DR)+ CD38-cells and higher percentage of natural killer lymphocytes, natural killer group 2A (NKG2A)+ MFI, percentage of CD8+CD38+cells, CD8+HLA-DR+MFI, CD8+NKG2A+MFI, and percentage of CD8+HLA-DR-CD38+cells. On multivariate regression, the CD8+HLA-DR+MFI, CD8+CD38+MFI, and total lymphocyte count were associated significantly with myocardial injury. CONCLUSION: Our findings suggest that lymphopenia, CD8+CD38+MFI, and CD8+HLA-DR+MFI are immune biomarkers of myocardial injury in hypertensive patients with COVID-19. The immune signature described here may aid in understanding the mechanisms underlying myocardial injury in these patients. The study data might open a new window for improvement in the treatment of hypertensive patients with COVID-19 and myocardial injury.

Viral Myopericarditis and Viral Encephalitis as Manifestations of Covid-19 Infection: A Case Report

Intro: Coronavirus disease (COVID-19) is currently a global health crisis and is caused by a new strain of coronavirus. However, emerging literature of case reports noted possible extrapulmonary manifestations of the disease. Because COVID 19 is a relatively new disease, at present, little existing literature tackles the diagnosis and therapeutic management of COVID-19-related conditions outside the pulmonary system. Method(s): This is a case of a 24-year-old male presented with the chief complaint of sudden stiffening of all extremities. Non-contrast computed tomography (CT) scan was unremarkable. Chest X-ray revealed interstitial pneumonia and SARS-CoV-2 RT-PCR (OPS/NPS) was positive. Electrocardiogram (ECG) findings showed supraventricular tachycardia and had elevated Troponin I levels. Pertinent physical findings noted were slurring of speech, dysmetria, and vertical nystagmus. Finding(s): The patient was initially treated as a case of Bacterial Abscess versus Viral encephalitis. Pericardial ultrasound revealed small pericardial effusion and was started on Colchicine. Repeat cranial CT scan noted unremarkable results but due to persistence of symptoms, the patient was started with Dexamethasone. On Day 16 of illness, the patient was noted to have full resolution of symptoms. Rapid antibody testing was done which revealed positive for both IgG and IgM hence the patient was discharged with the final diagnosis of Viral Myopericarditis resolved, Viral encephalitis resolved, COVID-19 pneumonia recovered. Conclusion(s): Extrapulmonary manifestations have been reported increasingly as an atypical presentation of COVID 19 infection. Early recognition of viral myopericarditis and viral encephalitis as a manifestation of COVID 19 can lead to the initiation of proper treatment and management. More reports on these cases can aid future studies on diagnostics and therapeutic approaches during the COVID-19 pandemic.Copyright © 2023

Covid-19 Vaccine-Induced Myositis

Background/Aims Through the COVID pandemic there have emerged reports of autoimmunity or new rheumatic diseases presenting in patients after they had COVID-19. This is thought to be caused by cross-reactivity of the COVID-19 spike protein to human antigens. Given the use of mRNA COVID-19 vaccinations which express the spike protein we might expect to see presentation of new rheumatic diseases following their use. We discuss a case where this appears to have occurred. Methods Our patient is a 24-year-old male with mixed phenotype acute leukaemia who had been treated with allogenic stem cell transplant and was currently in remission. He presented with fevers, palpitations, myalgia and bilateral arm and leg swelling. Symptoms began the day after receiving the first dose of an mRNA COVID-19 vaccination (Pfizer/BioNTech.) There were no other symptoms or recent change in medications. Physical examination revealed tender oedema in his forearms, biceps and thighs bilaterally with sparring of the hands. He had reduced power with shoulder (MRC 3/5), elbow (4), wrist (4+) and hip (4) movements. Observations revealed tachycardia and fevers up to 40C. Results Laboratory studies showed markedly elevated C-reactive protein (202), creatinine kinase (6697) and troponin (593) whilst investigations for infection were negative. An autoimmune panel was positive for anti- PM-SCL-75-Ab. An electrocardiogram showed sinus tachycardia. Echocardiogram was normal. Bilateral upper limb dopplers revealed no deep vein thrombus. An MRI of his thighs showed diffuse symmetrical oedema within the muscles, in keeping with an inflammatory myositis. A quadricep muscle biopsy showed evidence of MHC class 1 up-regulation, suggesting an inflammatory process. In addition, there were numerous macrophages evident in the endomysium. While this can be seen in graft-versus-host disease (GVHD), they would usually be found in the perimysium. After discussion between haematology, rheumatology and neurology, this was felt to be a case of vaccine induced myositis and myocarditis. Autoimmune myositis was thought to be less likely due to the relative sparing of the hands and the absence of Raynaud's phenomenon. 1 gram of intravenous methylprednisolone was then given for 3 days. The patient had a marked response with defervescence, improving laboratory markers, improved myalgia and decreased limb swelling. The patient was stepped down to a reducing regime of prednisolone and discharged. Due to relapse whilst weaning he has started on mycophenalate mofetil and rituximab and now continues to improve. Conclusion There are case reports of myositis following COVID-19 vaccination but our patient's case is complicated by the differential diagnosis of GVHD and concurrent myocarditis. Ongoing work is needed to clarify the exact link between vaccination and the presentation of a new inflammatory myositis, but it is important to recognise and start treatment early in order to preserve muscle bulk and ensure recovery.

Atrial Torsades De Pointes Post Covid Myocarditis

Background: Among patients with COVID-19 infection, the risk of adverse cardiovascular outcome, particularly myocarditis and dysrhythmias remain elevated at least up to one year after infection. We present a case of atrial tachycardia and atrial Torsades de Pointes from COVID myocarditis, persisted 6 months after infection, which was successfully managed by ablation. Objective(s): A 25-year-old female presented with mild COVID-19 infection, Omicron variant, in May 2022. One month after, her Covid infection resolved;she presented with symptomatic atrial tachycardia, paroxysmal atrial fibrillation and flutter. ECG showed multiple blocked premature atrial contractions (PAC) (Figure 1A). Holter monitor showed PAC triggered atrial tachycardia degenerating to paroxysmal atrial fibrillation, atrial Torsades de Pointes. She has mild persistent troponin elevation. Echocardiography was normal. Cardiac MRI showed evidence of mild myocarditis with subepicardial late Gadolinium enhancement (LEG) along the lateral mid-apical left ventricular wall and edema. (Figure 1B). She was treated with Colchicine for 2 months. Repeat cardiac MRI 4 months after COVID infection showed resolution of edema and LGE. However, her symptomatic PAC and atrial tachycardia did not respond to betablocker and amiodarone. She underwent electrophysiology study. Activation mapping of PAC using CARTO revealed earliest activation at the right anterior atrial wall, with close proximity to tricuspid valve;unipolar signal showed QS pattern, bipolar signal showed 16 msec pre-PAC (Figure 1C and 1D). Mechanical pressure from ThermoCool SmartTouch ablation catheter (Biosense Webster Inc.) at this site suppressed the PAC. Radiofrequency ablation resulted with an initial acceleration and then disappearance of the PAC. We did not isolate pulmonary veins or ablate cavotricuspid isthmus. Post ablation, PAC and atrial fibrillation were not inducible on Isoproterenol. Method(s): N/A Results: Covid myocarditis can result in dysrhythmia that lingers long after Covid myocarditis has resolved. Covid myocarditis can be caused by direct viral invasion of myocytes or more commonly is inflammatory related to cytokine release and edema. Our case demonstrates that dysrhythmias can persist despite resolution of myocarditis. Catheter ablation can successfully to treat these arrhythmias. Conclusion(s): This case highlights the importance of recognizing cardiac dysrhythmia as possible the long-term cardiac complications of COVID-19, requiring specific treatment such as catheter ablation.

Predictive Value of Myocardial injury in Patients with COVID-19 Admitted to a Quaternary Hospital in the City of Rio de Janeiro

Abstract Background In Brazil the factors involved in the risk of death in patients with COVID-19 have not been well established. Objective To analyze whether elevations of high-sensitivity troponin I (hTnI) levels influence the mortality of patients with COVID-19. Methods Clinical and laboratory characteristics of hospitalized patients with COVID-19 were collected upon hospital admission. Univariate and binary logistic regression analyzes were performed to assess the factors that influence mortality. P-value<0.05 was considered significant. Results This study analyzed192 patients who received hospital admission between March 16 and June 2, 2020 and who were discharged or died by July 2, 2020. The mean age was 70±15 years, 80 (41.7%) of whom were women. In comparison to those who were discharged, the 54 (28.1%) who died were older (79±12 vs 66±15years; P=0.004), and with a higher Charlson´s index (5±2 vs 3±2; P=0.027). More patients, aged≥60years (P <0.0001), Charlson´s index>1 (P=0.004), lung injury>50% in chest computed tomography (P=0.011), with previous coronary artery disease (P=0.037), hypertension (P=0.033), stroke (P=0.008), heart failure (P=0.002), lymphocytopenia (P=0.024), high D-dimer (P=0.024), high INR (P=0.003), hTnI (P<0.0001), high creatinine (P<0.0001), invasive mechanical ventilation (P<0.0001), renal replacement therapy (P<0.0001), vasoactive amine (P<0.0001), and transfer to the ICU (P=0.001), died when compared to those who were discharged. In logistic regression analysis, elevated hTnI levels (OR=9.504; 95% CI=1.281-70.528; P=0.028) upon admission, and the need for mechanical ventilation during hospitalization (OR=46.691; 95% CI=2.360-923.706; P=0.012) increased the chance of in-hospital mortality. Conclusion This study suggests that in COVID-19 disease, myocardial injury upon hospital admission is a harbinger of poor prognosis.

Prevalence of arrhythmia in COVID-19 patients with mild/moderate and severe illness: a prospective cohort study.

OBJECTIVES: The type of arrhythmias, and their prevalence in mild/moderate and severe COVID-19 patients admitted to the hospital are unknown from a prospective cohort study. METHODS: We did continuous electrocardiograms along with multiple ECGs in 305 consecutive hospitalized COVID-19 patients. RESULTS: The incidence of arrhythmias was 6.8% (21/305) in the target population. The incidence of arrhythmias was 9.2% (17/185) in patients with severe COVID-19 illness and 3.3% (4/120) in patients with mild/moderate COVID-19 illness with no significant difference (p = 0.063). All the arrhythmias were new-onset arrhythmias in this study. 95% (20/21) of these arrhythmias were atrial arrhythmia with 71.42% (15/21) being atrial fibrillation and one episode of sustained polymorphic ventricular tachycardia. No episode of high-grade atrioventricular block, sustained monomorphic ventricular arrhythmia, or torsades de pointes arrhythmias were observed in this study. The patients with arrhythmias were admitted to the intensive care unit (80.9% vs. 50.7%; p: 0.007), were on a ventilator (47.6% vs. 21.4%; p: 0.006), and had high in-hospital mortality (57.1% vs. 21.1%; p: 0.0001) than patients without arrhythmias. CONCLUSION: Atrial arrhythmias were the most frequent arrhythmias in hospital-admitted COVID-19 patients with atrial fibrillation being the most common arrhythmia.
