Acute symptomatic COVID-19 myocarditis: Case series

Background Coronavirus disease 2019 COVID-19 still remains a major cause of morbidity and mortality worldwide, mainly due to Acute Respiratory Distress Syndrome (ARDS). Nevertheless, other extra-pulmonary pathological aspects of COVID-19, notably cardiovascular, were disclosed as the global understanding of the pathogen agent advanced. Objectives To detect and evaluate acute myocarditis in patients with active and symptomatic COVID-19 infection. Materials and methods In this prospective analysis, patients presented with active COVID-19 illness and meeting the inclusion criteria were identified at the University Hospital Complex of Rabat between January and September 2021. Results Fifteen patients (8 males and 7 females) aged from 17 to 52 were included during the analysis period, the average delay between the confirmation of COVID-19 and the onset of myocarditis symptomatology was 17 days. The symptomatology was dominated by chest pain, unexplained cardiogenic shock and palpitations. The ECG showed essentially diffuse repolarization disorders. The inflammatory markers were significantly disturbed with an elevation of ultra-sensitive cardiac troponin I in all patients. Cardiac MRI showed impaired global longitudinal strain (GLS) myocardial edema, early and late subepicardial Gadolinium enhancement, compared to the control group (p < 0,01). Conclusion Cardiac involvement was detected in a proportion of patients with active COVID-19. Age, gender, clinical and electrical presentations didn't seem to influence the diagnosis. Cardiac MRI played an essential role for detecting and evaluating active myocarditis. Patients who presented myocardial injury had to have a longer follow-up as current understanding of long-term prognosis is still lacking.

Acute myocarditis and acute myopathy as the first manifestations of COVID-19, a case report

Coronavirus disease 2019 (COVID-19) mainly manifests with flu-like and respiratory symptoms such as fever, chill, myalgia, cough, dyspnea and in severe cases, it leads to acute respiratory distress syndrome and respiratory failure. However, there is evidence of extra-pulmonary involvements in patients with COVID-19. Some case reports and studies have reported severe and life-threatening complications related to COVID-19 such as cardiovascular complications (acute heart failure, myocarditis, acute coronary syndrome, thromboembolic events) and neuromuscular complications (stroke, transient ischemic attack, myositis, myopathy, Guillain-Barre syndrome). Here, we report a 51-year-old woman without a previous history of cardiovascular disease or neuromuscular disease referred to the emergency department of our hospital with new onset severe respiratory distress and progressive symmetric quadriparesis. We concluded that, the patient was infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and we therefore have encountered acute myocarditis and acute myopathy due to COVID-19 disease. In the intensive care unit (ICU), the patient was treated with oxygen therapy without mechanical ventilation, dexamethasone, intravenous human immunoglobulin (IVIG), beta interferon and remdesivir. The clinical feature, cardiac, respiratory, neuromuscular and hemodynamic parameters improved clearly five days after taking above mentioned treatments. The troponin, N-terminal pro-B type natriuretic peptide (NTproBNP), creatine phosphokinase (CPK), returned to normal values. Following improvement of cardiac and neurologic problems, the patient was transferred from ICU to general ward and then after 10 days, she was discharged with oral anticoagulant, anti-platelet, low-dose of corticosteroids and other conservative treatments. © 2023 The Author(s);Published by Society of Diabetic Nephropathy Prevention.

Immunomodulating Therapies in Acute Myocarditis and Recurrent/Acute Pericarditis.

The field of inflammatory disease of the heart or "cardio-immunology" is rapidly evolving due to the wider use of non-invasive diagnostic tools able to detect and monitor myocardial inflammation. In acute myocarditis, recent data on the use of immunomodulating therapies have been reported both in the setting of systemic autoimmune disorders and in the setting of isolated forms, especially in patients with specific histology (e.g., eosinophilic myocarditis) or with an arrhythmicburden. A role for immunosuppressive therapies has been also shown in severe cases of coronavirus disease 2019 (COVID-19), a condition that can be associated with cardiac injury and acute myocarditis. Furthermore, ongoing clinical trials are assessing the role of high dosage methylprednisolone in the context of acute myocarditis complicated by heart failure or fulminant presentation or the role of anakinra to treat patients with acute myocarditis excluding patients with hemodynamically unstable conditions. In addition, the explosion of immune-mediated therapies in oncology has introduced new pathophysiological entities, such as immune-checkpoint inhibitor-associated myocarditis and new basic research models to understand the interaction between the cardiac and immune systems. Here we provide a broad overview of evolving areas in cardio-immunology. We summarize the use of new imaging tools in combination with endomyocardial biopsy and laboratory parameters such as high sensitivity troponin to monitor the response to immunomodulating therapies based on recent evidence and clinical experience. Concerning pericarditis, the normal composition of pericardial fluid has been recently elucidated, allowing to assess the actual presence of inflammation; indeed, normal pericardial fluid is rich in nucleated cells, protein, albumin, LDH, at levels consistent with inflammatory exudates in other biological fluids. Importantly, recent findings showed how innate immunity plays a pivotal role in the pathogenesis of recurrent pericarditis with raised C-reactive protein, with inflammasome and IL-1 overproduction as drivers for systemic inflammatory response. In the era of tailored medicine, anti-IL-1 agents such as anakinra and rilonacept have been demonstrated highly effective in patients with recurrent pericarditis associated with an inflammatory phenotype.

Anti-SARS-CoV-2 vaccine-induced myocarditis - real but, in general, rare and mild: A consensus statement from the Studies Committee of the Portuguese Society of Cardiology.

Acute myocarditis (especially) and pericarditis have been consistently associated with the administration of vaccines against SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), generating anxiety in the general population, uncertainty in the scientific community and obstacles to ambitious mass vaccination programs, especially in foreign countries. Like some of its European counterparts, the Portuguese Society of Cardiology (SPC), through its Studies Committee, decided to take a position on some of the most pressing questions related to this issue: (i) How certain are we of this epidemiological association? (ii) What is the probability of its occurrence? (iii) What are the pathophysiological bases of these inflammatory syndromes? (iv) Should their diagnosis, treatment and prognosis follow the same steps as for typical idiopathic or post-viral acute myopericarditis cases? (v) Is the risk of post-vaccine myocarditis great enough to overshadow the occurrence of serious COVID-19 disease in unvaccinated individuals? In addition, the SPC will issue clinical recommendations and offer its outlook on the various paths this emerging disease may take in the future.

Acute Myocarditis and Heart Failure Associated with Multisystem Inflammatory Syndrome in Adults: A Rare Sequela of Coronavirus 2 Infection.

During the current pandemic, acute coronavirus disease 2019 (COVID-19) due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) provokes overwhelming inflammatory response leading to a wide range of clinical presentations including, a rare multisystem inflammatory syndrome and cardiac injury. Not only during the acute phase of the disease but a delayed immunologic response to SARS-CoV-2 infection among people with hyperinflammatory illness several weeks postacute phase of the infection is recently recognized. We report a young adult male who presented with acute myocarditis and heart failure associated with laboratory evidence of hyperinflammatory syndrome 5 weeks after a full recovery from COVID-19 infection. We believe that health-care providers need to be aware and recognize this syndrome as a rare sequela of COVID-19 infection.

Acute myocarditis in children: Features and outcomes of COVID-19 and NON-COVID patients

Background and Aim: The objective of the study was to assess the features of acute myocarditis and compare Covid19 and non-Covid19 cases. Method(s): Patients lt;18y with acute myocarditis (proved by virology and/or MRI and/or complete recovery of myocardial function) were included. Clinical data, echocardiographic parameters and outcomes were collected. Cases were divided in groups I (non-Covid), II (Covid). Result(s): From 1983 to 2021, 139 patients were included: 76 patients in group I and 63 in group II, 67males (31 in group I = 40% vs 36 in II = 57%). Mean age at diagnosis was 6.8 years: 4.2 years in group I vs 9.9 years in II. Heart failure (HF) was present at onset in 78% of cases in group I and 50% in group II: severe HF was more frequent in group I, chest pain was more frequent in II. Mean left ventricular shortening fraction (LVSF) at diagnosis was 23.8%: 18.4% in groups I vs 31.6% in II (plt;0.05). Mitral regurgi-tation was present in 63.8% of cases = 76.5% vs 43.8% respectively in groups I and II, pericarditis in 16.4% (no difference between groups), thromboembolic events occurred in 7% and arrhythmias in 10% ((all in group I). Virus was positive in 37.5% in group I and SARS-Cov2 positive in all of group II. Inotrope support was needed in 47%, mechanical circulatory support in 8% in group I only. Eleven patients died in group I, no death occurred in group II. One was transplanted(3rdmonth) and 19 have sequellae in group I. Complete recovery occurred in 74% of all cases: 40 of group I (58%) and all of group II (100%): time to recovery was longer in group I (2 years) than in group I (2 weeks). Mean LVSF improved from 18.4% at onset, to 24.6% at 1st month, 26.5% at 3rd month, 30.7% at 6th month and 38% at last FU in group I, while mean LVSF normalized within 2 weeks after onset in group II. Conclusion(s): Myocardial dysfunction and heart failure were less fre-quent, and complete recovery occurred promptly in COVID cases, while myocardial improvement progressed slowly within first 6months and beyond in half of non-COVID cases.

A Case Report for Acute Myopericarditis After NVX-CoV2373 (Novavax®) COVID-19 Vaccination.

Post-vaccination myocarditis after administration of the NVX-CoV2373 coronavirus disease 2019 (COVID-19) vaccine has been reported in a limited population. We report the first biopsy-proven case of myopericarditis after administration of second dose of NVX-CoV2373 COVID-19 vaccine (Novavax®) in Korea. A 30-year-old man was referred to emergency department with complaints of chest pain and mild febrile sense for two days. He received the second dose vaccine 17 days ago. Acute myopericarditis by the vaccination was diagnosed by cardiac endomyocardial biopsy. He was treated with corticosteroid 1 mg/kg/day for 5 days and tapered for one week. He successfully recovered and was discharged on the 12th day of hospitalization. The present case suggests acute myopericarditis as a vaccination complication by Novavax® in Korea.

Acute Myocarditis in a Patient Following mRNA-1273 SARS-CoV-2 Vaccination.

We herein report a case of acute myocarditis possibly related to the second dose of an mRNA-coronavirus disease 2019 vaccine in a 45-year-old woman with no remarkable medical history. She had a fever for one week following the second dose of the mRNA-1273 severe acute respiratory syndrome coronavirus 2 vaccine. One week later, she presented with chest pain and electrocardiogram changes. Her serum troponin levels were elevated upon admission. Echocardiography showed segmental wall motion abnormalities of the apex, apical portion of the anterior and inferior walls. The findings of cardiac magnetic resonance imaging were consistent with acute myocarditis.

Acute Myocarditis Following Vaccination With the First Dose of the mRNA-1273 Vaccine.

Viral infections are a common cause of acute myocarditis. However, vaccines including influenza and smallpox have also been rarely implicated. Recently, the coronavirus disease 2019 (COVID-19) vaccines have been associated with acute myocarditis. We describe a case of acute myocarditis in a 19-year-old male 2 days after the initial dose of the COVID-19 mRNA-1273 vaccine. He presented with chest pain radiating to his left arm and bilateral shoulders. COVID, influenza, coxsackie, respiratory syncytial virus polymerase chain reaction (PCR) tests were negative. Electrocardiogram revealed diffuse ST-segment elevation. Initial Troponin was 15.7 ng/mL. A coronary angiogram revealed patent coronary arteries and no wall motion abnormality. A transthoracic echocardiogram showed diffuse hypokinesis with an ejection fraction of 49%. Cardiac magnetic resonance scan was aborted after 2 attempts due to severe claustrophobia. His chest pain resolved following initiation of aspirin, tylenol, colchicine, lisinopril, and metoprolol.

Case Report: Disappearance of Late Gadolinium Enhancement and Full Functional Recovery in a Young Patient With SARS-CoV-2 Vaccine-Related Myocarditis.

Acute myocarditis was recently demonstrated in previously healthy young male patients after receipt of mRNA SARS-CoV-2 vaccines. Herein, we report on a 21-year-old man who presented with acute fatigue, myalgia, and chest pain 2 days after his second SARS-CoV-2 vaccination with BNT162b2. Cardiac magnetic resonance (CMR) showed acute myocarditis, with mildly impaired LV-function and abundant subepicardial late gadolinium enhancement (LGE). Control CMR after 3 months showed full functional recovery and complete disappearance of LGE. The benefits of SARS-CoV-2 vaccination may significantly exceed the very rare and, in this case, fully reversible adverse effects.

Ventricular tachycardia from myocarditis following COVID-19 vaccination with tozinameran (BNT162b2, Pfizer-BioNTech).

To combat the coronavirus disease 2019 (COVID-19) pandemic, many countries have started population vaccination programs using messenger ribonucleic acid (mRNA) vaccines. With the widespread use of such vaccines, reports are emerging worldwide, of the vaccine's association with the development of myocarditis. Younger men are more likely to develop postvaccine myocarditis, which usually presents as self-limiting chest pain within a week after the second dose. We present a case of myocarditis following vaccination with tozinameran (BNT162b2, Pfizer-BioNTech), which presented late, with ventricular tachycardia (VT) reduced left ventricular ejection fraction (LVEF).

Cardiac magnetic resonance findings in acute myocarditis after mRNA COVID-19 vaccination.

There is increasing evidence for myocarditis as a complication of the mRNA coronavirus disease 2019 (COVID-19) vaccination. We report the case of a 20-year-old previously healthy man who presented with fever and chest pain 2 days after the second dose of mRNA-1273 vaccine. Electrocardiogram and laboratory studies showed extensive ST-segment elevation accompanied by elevated cardiac biomarkers. Cardiac magnetic resonance (CMR) revealed late gadolinium enhancement (LGE) characteristics of myocarditis. The patient rapidly improved with conservative management and was discharged on hospital day 6. As an advantage over previous reports, we performed a 1-month follow-up CMR. It showed improvement in myocardial edema but persistence of LGE which may indicate irreversible fibrosis. CMR may be useful not only for diagnosis but also for prognostic evaluation of myocarditis after COVID-19 mRNA vaccination. .

Myocardial involvement in children with post-COVID multisystem inflammatory syndrome: a cardiovascular magnetic resonance based multicenter international study-the CARDOVID registry.

BACKGROUND: Recent evidence shows an association between coronavirus disease 2019 (COVID-19) infection and a severe inflammatory syndrome in children. Cardiovascular magnetic resonance (CMR) data about myocardial injury in children are limited to small cohorts. The aim of this multicenter, international registry is to describe clinical and cardiac characteristics of multisystem inflammatory syndrome in children (MIS-C) associated with COVID-19 using CMR so as to better understand the real extent of myocardial damage in this vulnerable cohort. METHODS AND RESULTS: Hundred-eleven patients meeting the World Health Organization criteria for MIS-C associated with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), having clinical cardiac involvement and having received CMR imaging scan were included from 17 centers. Median age at disease onset was 10.0 years (IQR 7.0-13.8). The majority of children had COVID-19 serology positive (98%) with 27% of children still having both, positive serology and polymerase chain reaction (PCR). CMR was performed at a median of 28 days (19-47) after onset of symptoms. Twenty out of 111 (18%) patients had CMR criteria for acute myocarditis (as defined by the Lake Louise Criteria) with 18/20 showing subepicardial late gadolinium enhancement (LGE). CMR myocarditis was significantly associated with New York Heart Association class IV (p = 0.005, OR 6.56 (95%-CI 1.87-23.00)) and the need for mechanical support (p = 0.039, OR 4.98 (95%-CI 1.18-21.02)). At discharge, 11/111 (10%) patients still had left ventricular systolic dysfunction. CONCLUSION: No CMR evidence of myocardial damage was found in most of our MIS-C cohort. Nevertheless, acute myocarditis is a possible manifestation of MIS-C associated with SARS-CoV-2 with CMR evidence of myocardial necrosis in 18% of our cohort. CMR may be an important diagnostic tool to identify a subset of patients at risk for cardiac sequelae and more prone to myocardial damage. CLINICAL TRIAL REGISTRATION: The study has been registered on ClinicalTrials.gov, Identifier NCT04455347, registered on 01/07/2020, retrospectively registered.

Cardiovascular magnetic resonance findings in young adult patients with acute myocarditis following mRNA COVID-19 vaccination: a case series.

BACKGROUND: Messenger RNA (mRNA) coronavirus disease of 2019 (COVID-19) vaccine are known to cause minor side effects at the injection site and mild global systemic symptoms in first 24-48 h. Recently published case series have reported a possible association between acute myocarditis and COVID-19 vaccination, predominantly in young males. METHODS: We report a case series of 5 young male patients with cardiovascular magnetic resonance (CMR)-confirmed acute myocarditis within 72 h after receiving a dose of an mRNA-based COVID-19 vaccine. RESULTS: Our case series suggests that myocarditis in this setting is characterized by myocardial edema and late gadolinium enhancement in the lateral wall of the left ventricular (LV) myocardium, reduced global LV longitudinal strain, and preserved LV ejection fraction. All patients in our series remained clinically stable during a relatively short inpatient hospital stay. CONCLUSIONS: In conjunction with other recently published case series and national vaccine safety surveillance data, this case series suggests a possible association between acute myocarditis and COVID-19 vaccination in young males and highlights a potential pattern in accompanying CMR abnormalities.

Acute myocarditis after a second dose of the mRNA COVID-19 vaccine: a report of two cases.

We report two cases of myocarditis, in two young and previously healthy individuals, temporally related to the second dose of the mRNA-COVID-19 vaccine. Both patients developed acute chest pain, changes on electrocardiogram (ECG), and elevated serum troponin within two days of receiving their second dose. Cardiac magnetic resonance (CMR) findings were consistent with acute myocarditis.

Acute myocarditis related to Covid-19 infection: 2 cases report.

INTRODUCTION AND IMPORTANCE: Since COVID 19 was described for the first time in December 2019, we have not stopped discovering its different clinical manifestations. Despite the respiratory complication which is the most common symptomatology, multi-organ dysfunction and multiple cardiovascular complications were described such as acute myocarditis, heart failure and even arrhythmias. CASES PRESENTATION: Two patients aged 26 and 56 year-old, developed acute myocarditis related to Covid-19 infection but with different symptomatology. CASE 1: Presented to the emergency room with digestive symptomatology, Covid-19 infection was confirmed by a positive chest CT scan and positive COVID-19 serology testing. Clinical, biological, radiological findings allowed making the diagnosis of a Covid-19 infection with a bacterial superinfection complicated by a fulminant myocarditis. CASE 2: Presented to the emergency department with a chest pain, dyspnoea, paroxistic cough, myalgia and fever. A Covid-19 infection was confirmed. The electrocardiogram showed a diffuse ST elevation, echocardiography showed normal systolic function and the high-sensitivity cardiac troponin I level was high. Invasive coronary angiography was performed, revealing angiographically normal coronary arteries. CLINICAL DISCUSSION: Our 2 cases were treated differently, case 1 received antibiotherapy because of the bacterial superinfection and inotropic support for the septic and cardiogenic choc. Contrarily to case 2 who received inotropic support, immunoglobulin and corticosteroid. With a total recovery for both patients. CONCLUSION: This article can help in considering cardiac affection due to SARS-CoV2, even with poor respiratory symptomatology, and to insist on the importance of the cardiac evaluation for young patients with a sever Covid-19 infection.

Chest pain and high troponin level without significant respiratory symptoms in young patients with COVID-19.

BACKGROUND: Of all patients infected with COVID-19, 95% have mild symptoms, but 5% may experience severe illness. There are reports of myocardial injury associated with the COVID19 infection in middle-aged and old people with baseline cardiac conditions. Acute myocardial injury has been suggested as a marker for disease severity. Sometimes it is hard to differentiate between acute coronary syndrome and acute myocarditis; hence detailed history taking, lab tests and imaging will be necessary. CASE PRESENTATION: Herein, we described two young patients presenting with chest pain and no significant respiratory symptoms, one without cardiovascular risk factors and another one with diabetes mellitus and cigarette smoking. COVID-19 was documented with real-time reverse-transcriptase-polymerase chain reaction (rRT-PCR). CONCLUSION: Early Chest CT scan besides coronary CT angiogram (if available) in suspicious cases can help physician to make fast decisions. These two cases both had complication-free hospital stay. Despite markedly high on-admission troponin levels, which is known as a marker of poor prognosis they discharged in good condition. One month follow-up was also uneventful.

A Case of Hemolytic Anemia With Acute Myocarditis and Cardiogenic Shock: A Rare Presentation of COVID-19.

Coronavirus disease 2019 (COVID-19) cases are on the rise globally, and mortality- and survival-related data are emerging every day. In addition, upcoming reports are suggestive of increased risk of cardiac ailments in high-risk patients. In the context of cardiac involvement, acute myocarditis has become one of the unexplored areas in COVID-19 patients, which could influence the long-term outcomes. In this report, we present a rare case that warrants further study on the subject due to the paucity of data in the literature. To date, no case of severe hemolytic anemias with stress cardiomyopathy/acute myocarditis in a patient of COVID-19 has been formally reported in the literature. The bedside echocardiogram had shown a possibility of acute myocarditis. The patient's marked left ventricular (LV) functional recovery without coronary intervention further corroborates the same. Clinicians should be aware of the diversity of cardiovascular/hematological complications, as well as focused cardiac ultrasound study and the importance of echocardiography as a good screening modality for cardiovascular and hematological complications of COVID-19 infection.
