Cardiac Tamponade Secondary to COVID-19

Association between echocardiographic features, troponin levels, and survival time in hospitalized COVID-19 patients with cardiovascular events

Introduction

This study aims to explore the predictive roles of echocardiographic parameters and biomarkers in determining outcomes among hospitalized COVID-19 patients experiencing cardiovascular events.

Methods

A retrospective cohort study was conducted involving 49 COVID-19 patients who encountered cardiovascular events during hospitalization and underwent echocardiography. Our findings revealed notable associations between echocardiographic parameters and survival time.

Results

A decrease in left ventricular ejection fraction (LVEF) of 10% was linked to a 20% reduction in survival time (TR: 0.80, 95% CI: 0.67 - 0.96, p = .017). Similarly, an increase in left ventricular (LV) volume by 10 mL was associated with a 9% decrease in survival time (TR: 0.91, 95% CI: 0.84 - 0.98, p = .011). Moreover, an increase in left atrial (LA) volume by 10 mL corresponded to an 8% decrease in survival time (TR: 0.92, 95% CI: 0.86 - 0.99, p = .026). Additionally, each 1 cm increase in right ventricular (RV) diameter was linked to a 22% reduction in survival time (TR: 0.78, 95% CI: 0.61 - 0.99, p = .043). Furthermore, a 10 mL increase in right atrial (RA) volume was associated with a 12% decrease in survival time (TR: 0.88, 95% CI: 0.78 - 0.98, p = .017). Notably, a tenfold rise in troponin levels was linked to a 33% decrease in survival time (TR: 0.67, 95% CI: 0.48 - 0.93, p = .014).

Conclusions

Our study emphasizes the significant associations between various echocardiographic parameters and troponin levels with reduced survival time among COVID-19 patients experiencing cardiovascular events. These findings highlight the potential utility of echocardiography and troponin assessment in predicting outcomes and guiding management strategies in this patient population.

Incidence and Impact of Takotsubo Syndrome in Hospitalized Patients With COVID-19

BACKGROUND

Takotsubo syndrome has been reported in patients with COVID-19, although minimal data are available. This investigation assessed the incidence and impact of takotsubo syndrome on patients hospitalized with COVID-19.

METHODS

A retrospective cohort study was conducted using International Statistical Classification of Diseases, Tenth Revision, codes to identify patients with a primary diagnosis of COVID-19 with or without takotsubo syndrome in the National Inpatient Sample 2020 database. Outcomes between groups were compared after propensity score matching for patient and hospital demographics and comorbidities.

RESULTS

A total of 211,448 patients with a primary diagnosis of COVID-19 were identified. Of these, 171 (0.08%) had a secondary diagnosis of takotsubo syndrome. Before matching, patients with COVID-19 and takotsubo syndrome, compared with patients without takotsubo syndrome, were older (68.95 vs 64.26 years; P < .001); more likely to be female (64.3% vs 47.2%; P < .001); and more likely to have anxiety (24.6% vs 12.8%; P < .001), depression (17.5% vs 11.4%; P = .02), and chronic obstructive pulmonary disease (24.6% vs 14.7%; P < .001). The takotsubo syndrome group had worse outcomes than the non-takotsubo syndrome group for death (30.4% vs 11.1%), cardiac arrest (7.6% vs 2.1%), cardiogenic shock (12.9% vs 0.4%), length of hospital stay (10.7 vs 7.5 days), and total charges ($152,685 vs $78,468) (all P < .001). After matching and compared with the non-takotsubo syndrome group (n = 508), the takotsubo syndrome group (n = 170) had a higher incidence of inpatient mortality (30% vs 14%; P < .001), cardiac arrest (7.6% vs 2.8%; P = .009), and cardiogenic shock (12.4% vs 0.4%; P < .001); a longer hospital stay (10.7 vs 7.6 days; P < .001); and higher total charges ($152,943 vs $79,523; P < .001).

CONCLUSION

Takotsubo syndrome is a rare but severe in-hospital complication in patients with COVID-19.

Subacute hemorrhagic pericardial tamponade after COVID-19 infection mimicking carcinomatous pericarditis: a case report

Background

Coronavirus disease (COVID-19)-associated acute pericarditis has recently received much attention owing to its high frequency associated with pericardial tamponade (PT), showing unfavorable prognosis. However, early diagnosis and treatment remain challenging in cases of non-specific signs and symptoms.

Case presentation

A 64-year-old man was admitted to our hospital for acute osteomyelitis of the toes and was properly treated with antimicrobial agents. Three days after admission, the patient developed mild COVID-19 without pneumonia, for which early anti-COVID-19 agents were initiated. Nevertheless, the patient developed hemorrhagic PT due to acute pericarditis 2 weeks later, which was confirmed by cardiac magnetic resonance, requiring an urgent pericardiocentesis. Although cytological analysis of the hemorrhagic pericardial fluid strongly suggested adenocarcinoma, the atypical cells were eventually proven to be mesothelial cells with reactive atypia. Furthermore, lymph nodes swelling with abnormal 2-[18F]-fluoro-2-deoxy-D-glucose accumulation on imaging were suggestive of malignancy. However, biopsy examination revealed multiple non-caseating granulomas in the lymph node, unlikely due to malignancy. Eventually, the temporal association of the preceding COVID-19 with the occurrence of subacute PT without other identifiable cause led to a final diagnosis of COVID-19-associated acute pericarditis. With anti-inflammatory and corticosteroids treatment, the patient's symptoms involving the pericardial structure and function were completely resolved along with improvements in size of the affected lymphadenopathies.

Conclusions

We encountered a unique case of COVID-19-associated acute pericarditis exhibiting hemorrhagic PT. This case underscores the residual risk of delayed pericardial involvement even in patients with mild COVID-19 who receive early treatment, and the recognition that COVID-19 may cause various cytomorphological and histological features. Additionally, the importance of considering this rare entity as a cause of hemorrhagic pericardial effusions should be highlighted.

Takotsubo syndrome before and during the COVID-19 pandemic in Austria: a retrospective cohort study (TOSCA-19)

AIMS

This study aims to investigate the prevalence of Takotsubo syndrome (TTS) as a percentage of the total number of acute coronary syndrome (ACS), including non-STE-elevation myocardial infarction and ST-elevation myocardial infarction, as well as the short-term outcome of TTS patients before and during the COVID-19 pandemic.

METHODS AND RESULTS

We compared patients from two different periods: (i) Period 1 (before the COVID-19 pandemic): 1 March to 30 December 2019, and (ii) Period 2 (during the COVID-19 pandemic): 1 March to 30 December 2020. The retrospective database was created from the archives of the participating hospitals or electronic hospital systems by trained medical personnel. The subjects' medical history, cardiovascular risk factors, laboratory values, echocardiography findings, and an in-hospital outcome were variables of interest. Furthermore, propensity score matching analysis was performed to evaluate the short-term prognosis in TTS and ACS patients. Altogether six Austrian centres-(i) 3rd Medical Department of Cardiology and Intensive Care Medicine, Clinic Ottakring, Vienna, Austria; (ii) 5th Medical Department of Cardiology, Clinic Favoriten, Vienna, Austria; (iii) 2nd Medical Department, Hanusch Hospital, Vienna, Austria; (iv) University Clinic of Internal Medicine III, Cardiology and Angiology, Medical University of Innsbruck, Austria; (v) Department of Cardiology, University Hospital Graz, Graz, Austria; (vi) Department of Cardiology and Intensive Medicine, Kepler University Clinic, Linz, Austria-participated in the study. During period 1, 87 (3.5%) patients out of 2482 ACS patients had TTS in all participating centres. During period 2, 71 (2.7%) patients out of 2572 ACS patients had TTS in all participating centres. Accordingly, the prevalence of TTS remained stable irrespective of potential psychologic stress during the COVID pandemic. Furthermore, the baseline characteristics of TTS patients did not change during the COVID-19 pandemic. The prevalence of in-hospital complications [cardiogenic shock (4.6% vs. 4.3%, P = 0.925), ventricle thrombus (1.1% vs. 1.4%, P = 0.885) and in-hospital bleeding (3.4% vs. 1.4%, P = 0.417)] remained stable. The all-cause in-hospital mortality of TTS patients did not change during the COVID-19 pandemic [χ2 (2) = 0.058, P = 0.810]. Moreover, a propensity score matching analysis of all-cause in-hospital mortality between matched TTS and ACS patients showed higher in-hospital mortality in ACS patients during COVID-19 pandemic (P = 0.043).

CONCLUSIONS

Despite the well-known increased psychologic stress during the COVID-19 pandemic, the prevalence of TTS during the COVID-19 pandemic and the short-term clinical outcome in Austria remained unimpacted.

Prognostic value of R wave peak time in COVID-19 pneumonia

BACKGROUND

R wave peak time (RWPT) is also known as intrinsicoid deflection time or ventricular activation time. It shows the conduction time from the endocardium in the ventricle to the epicardium. It provides diagnostic and prognostic information for many cardiovascular diseases, such as RWPT prolongation, left ventricular hypertrophy, volume overload, conduction system abnormalities, and myocardial ischemia. Objectives The aim of this study is to investigate the relationship between COVID-19 mortality and RWPT in superficial ECG.

METHODS

This study retrospectively examined 640 patients diagnosed with COVID-19 and treated in an intensive care unit at a single center between January 2021 and June 2022. All patients included in the study had clinical and radiological characteristics and signs of COVID-19 pneumonia.

RESULTS

640 patients included in the study were divided into 2 groups: surviving and deceased. There were 510 patients in the surviving group and 130 patients in the deceased group. The deceased group was found to be significantly older. The number of patients with COPD was higher in the deceased group. Troponin, lactate dehydrogenase (LDH), C-reactive protein (CRP), D-dimer and T-peak to T-end interval(Tpe) and RWPT were found to be significantly increased in the deceased group. In binary logistic regression analysis; age, COPD, LDH, CRP, troponin, D-dimer, Tpe interval, RWPT were determined as independent risk factors for mortality.

CONCLUSIONS

Prolonged RWPT is useful in risk stratification for COVID-19 pneumonia mortality.

COVID-19-Induced Cardiac Tamponade: A Case Study and a Literature Review

COVID-19 presentation is heterogeneous. As a viral illness, it could cause pericardial effusion leading to cardiac tamponade. We present a patient coursing with this viral illness that was found to have cardiac tamponade. We report a case of a 79-year-old female who presented with shortness of breath and dry cough for one week and resulted positive for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Her initial chest X-ray showed a bottle-shaped heart. Computed chest tomography showed pericardial effusion, and an echocardiogram confirmed moderated pericardial effusion with signs of tamponade. He improved with conservative therapy with colchicine, ibuprofen, cefepime, dexamethasone, dolutegravir, and apixaban for pulmonary emboli. An early approach in cardiac tamponade induced by COVID-19 is crucial to promptly address an aggressive directed therapy, avoiding potential complications or unnecessary procedures.

Comorbidities and clinical complications associated with SARS-CoV-2 infection: an overview

The novel severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) causes major challenges to the healthcare system. SARS-CoV-2 infection leads to millions of deaths worldwide and the mortality rate is found to be greatly associated with pre-existing clinical conditions. The existing dataset strongly suggests that cardiometabolic diseases including hypertension, coronary artery disease, diabetes and obesity serve as strong comorbidities in coronavirus disease (COVID-19). Studies have also shown the poor outcome of COVID-19 in patients associated with angiotensin-converting enzyme-2 polymorphism, cancer chemotherapy, chronic kidney disease, thyroid disorder, or coagulation dysfunction. A severe complication of COVID-19 is mostly seen in people with compromised medical history. SARS-CoV-2 appears to attack the respiratory system causing pneumonia, acute respiratory distress syndrome, which lead to induction of severe systemic inflammation, multi-organ dysfunction, and death mostly in the patients who are associated with pre-existing comorbidity factors. In this article, we highlighted the key comorbidities and a variety of clinical complications associated with COVID-19 for a better understanding of the etiopathogenesis of COVID-19.

Colchicine Drug Interaction Errors and Misunderstandings: Recommendations for Improved Evidence-Based Management

Colchicine is useful for the prevention and treatment of gout and a variety of other disorders. It is a substrate for CYP3A4 and P-glycoprotein (P-gp), and concomitant administration with CYP3A4/P-gp inhibitors can cause life-threatening drug-drug interactions (DDIs) such as pancytopenia, multiorgan failure, and cardiac arrhythmias. Colchicine can also cause myotoxicity, and coadministration with other myotoxic drugs may increase the risk of myopathy and rhabdomyolysis. Many sources of DDI information including journal publications, product labels, and online sources have errors or misleading statements regarding which drugs interact with colchicine, as well as suboptimal recommendations for managing the DDIs to minimize patient harm. Furthermore, assessment of the clinical importance of specific colchicine DDIs can vary dramatically from one source to another. In this paper we provide an evidence-based evaluation of which drugs can be expected to interact with colchicine, and which drugs have been stated to interact with colchicine but are unlikely to do so. Based on these evaluations we suggest management options for reducing the risk of potentially severe adverse outcomes from colchicine DDIs. The common recommendation to reduce the dose of colchicine when given with CYP3A4/P-gp inhibitors is likely to result in colchicine toxicity in some patients and therapeutic failure in others. A comprehensive evaluation of the almost 100 reported cases of colchicine DDIs is included in table form in the electronic supplementary material. Colchicine is a valuable drug, but improvements in the information about colchicine DDIs are needed in order to minimize the risk of serious adverse outcomes.

Takotsubo Cardiomyopathy and COVID-19: A Case Report and Literature Review

BACKGROUND

Takotsubo cardiomyopathy is characterized by transient regional ventricular abnormalities in the absence of coronary artery disease and is reported as a complication of COVID-19.

CASE PRESENTATION

It can have a diverse clinical presentation, occasionally resembling an acute coronary syndrome, and progress to acute heart failure and cardiogenic shock, adversely affecting patients' prognosis. A high index of suspicion and a thorough diagnostic approach supported by ancillary studies like echocardiography and coronary angiography is key for an accurate diagnosis and correct medical treatment. Herein, we report a patient with severe COVID-19 who developed Takotsubo cardiomyopathy.

CONCLUSION

We also present a detailed literature review regarding the relationship between COVID-19 and Takotsubo cardiomyopathy.

Takotsubo syndrome and COVID‐19: A systematic review

Background and Aims

Takotsubo syndrome (TTS), also known as stress cardiomyopathy, is characterized by acute and transient left ventricular dysfunction and has increased during the COVID-19 pandemic. Herein, we aim to review studies on TTS that were associated with COVID-19 infection, vaccine, and other COVID-19-related etiologies including psychosocial stressors.

Methods

We systematically searched PubMed, EMBASE, and Scopus up to May 12, 2022. We included case reports, case series, and original articles that reported at least one TTS case associated with COVID-19, or TTS cases after receiving COVID-19 vaccines, or TTS cases secondary to psychological stress due to the COVID-19 pandemic. The quality assessment was conducted using the Joanna Briggs Institute checklist.

Results

Sixty-seven articles including 102 cases were included. Hypertension was the most frequently accompanying comorbidity (N = 67 [65.6%]) and the mean left ventricular ejection fraction was 36.5%. Among COVID-19 patients, the in-hospital mortality rate was 33.3%. On the other hand, only one COVID-19-negative individual expired (2.3%). The most common presenting clinical symptom was dyspnea in 42 (73.6%) patients. the mean time interval from the first symptom to admission was 7.2 days. The most common chest imaging finding was ground-glass opacity which was reported in 14 (31.1%) participants. The most common abnormalities were T-wave inversion in 35 (43.2%) and ST-segment elevation in 30 (37%). Brain natriuretic peptide and troponin were elevated in 94.7% and 95.9% of participants, respectively.

Conclusion

The TTS in patients with COVID-19 is almost rare, whereas it could lead to a great mortality and morbidity. An individual with COVID-19, especially an elderly woman, presented with dyspnea in addition to a rise in brain natriuretic peptide and troponin should be evaluated for TTS.

Acute Pericarditis as the Primary Presentation of COVID-19 Infection followed by Guillain-Barre Syndrome in a Healthy Young Man: A Case Report

Background

Symptomatic COVID-19 infection most often presents as acute respiratory distress syndrome. Acute pericarditis and Guillain-Barré syndrome are rare extrapulmonary manifestations of this infection.

Case Presentation

A 27-year-old man presented with chest pain, with negative troponin and typical electrocardiographic findings, resulting in a diagnosis of acute pericarditis. He had no respiratory symptoms, nor the chest computerized tomography (CT) scan findings of COVID-19, and his Polymerase chain reaction (PCR) was negative. One week later, he developed clinical symptoms of Guillain-Barre syndrome, along with respiratory manifestations of COVID-19. His repeat chest CT scan and PCR test confirmed COVID-19 infection. After 17 days of hospital stay, he improved clinically and was discharged.

Conclusion

This is the first case of acute pericarditis as the primary presentation of COVID-19 in the absence of respiratory symptoms and a clear chest CT scan, followed by the development of Guillain-Barré syndrome and respiratory tract manifestations of COVID-19. Clinicians should be aware of the extrapulmonary presentation of COVID-19 infection.

Efficacy and safety profile of corticosteroids and non-steroidal anti-inflammatory drugs in COVID-19 management: A narrative review

Due to the fact that coronavirus disease 2019 (COVID-19) is still prevalent, and current reports show that some parts of the world have seen increase in incidence, it is relevant that health professionals and scientists know about recent or novel trends, especially drug treatments. Additionally, the safety profiles of these drug treatments need to be documented and shared with the public. Some studies have demonstrated the clinical benefits of non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids in COVID-19 treatment. On the contrary, others have also reported that NSAIDs and corticosteroids may worsen symptoms associated with COVID-19. While some researchers have suggested that corticosteroids may be helpful if used in the early stages of COVID-19, there are still some conflicting findings regarding the use of corticosteroids in certain viral infections. Our review suggests that methylprednisolone, dexamethasone, and ibuprofen have therapeutic potential in reducing mortality due to COVID-19 among hospitalized patients. This review also highlights the fact that the use of NSAIDs is not associated with adverse outcomes of COVID-19. In reality, evidence suggests that NSAIDs do not increase the risk of COVID-19 infections. Also, the literature reviewed suggests that corticosteroid treatment in COVID-19 was linked with a decrease in all-cause mortality and disease progression, without increase in adverse events when compared to no corticosteroid treatment.

Cardiac complications in patients with COVID-19: a systematic review

Cardiac complications in patients with COVID-19 have been described in the literature with an important impact on outcome. The primary objective of our systematic review was to describe the kind of cardiac complications observed in COVID-19 patients and to identify potential predictors of cardiovascular events. The secondary aim was to analyze the effect of cardiac complications on outcome.

We performed this systematic review according to PRISMA guidelines using several databases for studies evaluating the type of cardiac complications and risk factors in COVID-19 patients. We also calculated the risk ratio (RR) and 95% CI. A random-effects model was applied to analyze the data. The heterogeneity of the retrieved trials was evaluated through the I² statistic. Our systematic review included 49 studies. Acute cardiac injury was evaluated in 20 articles. Heart failure and cardiogenic shock were reported in 10 articles. Myocardial infarction was evaluated in seven of the papers retrieved. Takotsubo, myocarditis, and pericardial effusion were reported in six, twelve, and five articles, respectively. Arrhythmic complications were evaluated in thirteen studies. Right ventricular dysfunction was evaluated in six articles. We included 7 studies investigating 2115 patients in the meta-analysis. The RR was 0.20 (95% CI: 0.17 to 0.24; P < 0.00001, I² = 0.75). Acute cardiac injury represented the prevalent cardiac complications observed in COVID-19 patients (from 20 to 45% of the patients). Patients with acute cardiac injury seemed to be significantly older, with comorbidities, more likely to develop complications, and with higher mortality rates. Acute cardiac injury was found to be an independent risk factor for severe forms of SARS-CoV-2 infection and an independent predictor of mortality. Due to the scarce evidence, it was not possible to draw any conclusion regarding Takotsubo, myocarditis, pleural effusion, and right ventricular dysfunction in COVID-19 patients. Noteworthy, possible arrhythmic alterations (incidence rate of arrhythmia from 3 to 60%) in COVID-19 patients have to be taken into account for the possible complications and the consequent hemodynamic instabilities. Hypertension seemed to represent the most common comorbidities in COVID-19 patients (from 30 to 59.8%). The prevalence of cardiovascular disease (CVD) was high in this group of patients (up to 57%), with coronary artery disease in around 10% of the cases. In the majority of the studies retrieved, patients with CVD had a higher prevalence of severe form, ICU admission, and higher mortality rates.

Myocarditis Related to COVID-19 and SARS-CoV-2 Vaccination

The coronavirus disease of 2019 (COVID-19) has been a cause of significant morbidity and mortality worldwide. Among the short- and long-term consequences of COVID-19, myocarditis is a disease to be taken into consideration. Myocarditis, in general, is related to a poor prognosis. However, the epidemiology and prognosis of myocarditis related to COVID-19 are currently unknown. While vaccination against COVID-19 is of great benefit at a public health level, the risk of myocarditis should be considered in the context of the global benefits of vaccination. In this narrative review, we will summarize the etiopathogenic bases, the epidemiology, the clinical manifestations, the course, diagnosis, prognosis, and the treatment of myocarditis related to SARS-CoV-2, as well as myocarditis secondary to mRNA vaccines.

Potential Cardiac Tamponade Development Secondary to SARS-CoV-2 Infection

Upon initial discovery in late 2019, severe acute respiratory syndrome coronavirus 2, SARS-CoV-2, has managed to spread across the planet. A plethora of symptoms affecting multiple organ systems have been described, with the most common being nonspecific upper respiratory symptoms: cough, dyspnea, and wheezing. However, the cardiovascular system is also at risk following COVID-19 infection. Numerous cardiovascular complications have been reported by physicians globally, in particular cardiac tamponade Physicians must hold a high index of suspicion in identifying and treating patients with cardiac tamponade who may have contracted the novel coronavirus. This review will describe the current epidemiology and pathophysiology of SARS-CoV-2 and cardiac tamponade, highlighting their clinical course progression and the implications it may have for the severity of both illnesses. The paper will also review published case reports of cardiac tamponade, clinical presentation, and treatment of this complication, as well as the disease as a whole.

Subacute Cardiac Tamponade in a COVID-19 Patient Despite Negative Testing

COVID-19 infection has been documented to cause a wide range of symptoms including cardiac complications. We present a case of subacute cardiac tamponade in a patient infected with COVID-19 in the absence of respiratory symptoms; we also review the current literature on this rare sequela. Our patient is a 67-year-old man who presented to the hospital due to intermittent chest pain for three weeks. COVID-19 polymerase chain reaction (PCR) testing was negative two times. He had an outpatient echocardiogram that showed a moderate pericardial effusion about a week prior to the hospital presentation. On admission, a repeat echocardiogram showed a large pericardial effusion with tamponade physiology. Pericardiocentesis did not reveal a clear etiology of the hemorrhagic effusion but four days later, the patient was found to be positive for COVID-19 infection without any clear respiratory illness. Given the absence of other etiology and negative workup, cardiac tamponade was attributed to pericardial inflammation from this virus and our patient improved with colchicine and steroids. We, therefore, advise providers to consider COVID-19 as a cause of hemorrhagic, cryptogenic cardiac tamponade despite negative COVID-19 testing. We also review 42 additional reported cases of cardiac tamponade in patients infected with COVID-19. COVID-19 can cause cardiac tamponade even in the absence of pulmonary disease. This case and literature review highlight tamponade as a rare complication of COVID-19 and should be considered in the differential of any acute deterioration in this patient population.

Takotsubo Syndrome during COVID-19 Pandemic in the Veneto Region, Italy

Background: During the COVID-19 pandemic, the risk of SARS-CoV-2 infection, the public health measures of social distancing, the freedom limitations, quarantine, and the enforced homeworking under the lockdown period, as well as medical causes including COVID-19 infection per se, may have caused major emotional distress, especially in the most vulnerable patients. We aimed to evaluate the variations in the number of admissions due to Takotsubo syndrome (TTS) during the COVID-19 pandemic in the Veneto region. Methods: We retrospectively reviewed and analyzed the number of admissions because of TTS in 13 Divisions of Cardiology located in the Veneto region, the northeastern area of Italy, covering a population of more than 2.5 million inhabitants, during the two major pandemic waves of COVID-19 (the first between 15 March and 30 April 2020 and the second between 15 November and 30 December 2020) that occurred in 2020. Results: In total, 807 acute coronary syndromes were admitted in the 13 enrolling hospitals. Among these, 3.9% had TTS. Compared to the corresponding 2018 and 2019 time periods, we observed a significant increase in the number of TTS cases (+15.6%, p = 0.03 and +12.5%, p = 0.04, comparing 2018 to 2020 and 2019 to 2020, respectively). Geographical distribution of the TTS cases reflected the broad spread of the SARS-CoV-2 infection with a significant direct relationship between TTS incidence and the number of COVID-19 infections according to Pearson’s correlation (r = 0.798, p < 0.001). Conclusions: The higher incidence of TTS during the 2020 COVID-19 pandemic waves, especially in the areas that were hit hardest in terms of morbidity and mortality by the SARS-CoV-2 infection, suggest a strong direct and/or indirect role of COVID-19 in the pathogenesis of TTS.

Electrocardiographic Abnormalities in Hospitalized Patients with COVID-19 and the Associations with Clinical Outcome

The cardiovascular (CV) system can often be affected during SARS-CoV-2 infection and several acute manifestations, such as myocardial infarction, pericarditis, myocarditis and arrhythmias have been described. We provide a retrospective overview of electrocardiographic (ECG) features and their relationship with clinical outcomes in a cohort of patients admitted to our COVID-19 Unit between November 2020 and May 2021. Resting standard 12-lead ECGs were performed in all patients at admission and in those recovering from SARS-CoV-2 infection also at discharge. Clinical and serological records alongside ECG measurements were retrospectively evaluated and statistical analysis was performed to identify relationships between variables. A total of 123 patients (44% females) with a mean age of 73.9 years were enrolled. Ninety-five (77%) patients recovered from SARS-CoV-2 infection and were discharged while 28 (23%) died in hospital. Almost 90% of patients displayed at least one CV risk factor and 41 (33%) patients had at least one previous CV event. We observed that heart rate, corrected QT interval dispersion (QTcd) and inverted T waves are independently associated with in-hospital death and inverted T waves show the strongest association. This association remained significant even after correcting for the number of CV risk factors at baseline and for the type of CV risk factor at baseline. Our study demonstrated that some ECG abnormalities at admission are independently associated with in-hospital death regardless of pre-existing CV risk factors. These findings may be of particular relevance in clinical settings with limited access to advanced techniques, such as cardiac magnetic resonance and could help improve the outcomes of patients with cardiac involvement related to SARS-CoV-2 infection.

COVID-19 Myopericarditis With Pericardial Effusion Complicated With Cardiac Tamponade and Rhabdomyolysis

COVID-19 infection is a complex multi-organ disease, including the cardiovascular system, which may present with myocarditis. A 42-year-old female presented to our ED with generalized weakness, myalgia, and epigastric pain. Laboratory workup showed a positive SARS-CoV-2 polymerase chain reaction (PCR). An ECG showed sinus tachycardia with low voltage. A bedside echocardiogram showed a pericardial effusion with cardiac tamponade. An emergent pericardiocentesis was performed with immediate hemodynamic improvement. The patient was admitted to the coronary care unit (CCU), and colchicine and ibuprofen were started for pericarditis. Pericardial fluid bacterial and fungal cultures were negative, and serum antinuclear antibodies were also negative. On day 5 of hospitalization, creatine kinase (CK) level was high compared to on presentation. COVID-induced rhabdomyolysis was suspected and was dramatically improved with IV fluids. The patient was discharged on day 7 of admission. Our case shows that COVID-19 can present with an uncommon presentation like cardiac tamponade. Further studies are warranted to better understand the pathogenesis and management of COVID-19 myopericarditis.

COVID-19-Induced Myopericarditis Leading to Cardiac Tamponade: An Unusual Case Presentation

Coronavirus disease 2019 (COVID-19) can manifest differently in different patients, ranging from asymptomatic carriers to acute respiratory distress syndrome (ARDS). Cardiac involvement may occur with COVID-19 even without respiratory tract signs and symptoms of infection. Cardiac manifestations like heart failure (HF), myopericarditis, and cardiac arrhythmias are commonly reported. Cardiac injury with troponin leak is associated with increased mortality in COVID-19, and its clinical and radiographic features are difficult to distinguish from those of HF. COVID-19 is also known to cause pericardial inflammation, likely via direct cytotoxic effects or immune-mediated mechanisms. However, the definite mechanism is still unclear. We present here a case of myopericarditis complicated by pericardial effusion and cardiac tamponade in a COVID-19 infected patient with minimal pulmonary involvement.

A Real Pandora's Box in Pandemic Times: A Narrative Review on the Acute Cardiac Injury Due to COVID-19

The intricate relationship between severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the cardiovascular system is an extensively studied pandemic topic, as there is an ever-increasing amount of evidence that reports a high prevalence of acute cardiac injury in the context of viral infection. In patients with Coronavirus disease 2019, COVID-19, a significant increase in serum levels of cardiac troponin or other various biomarkers was observed, suggesting acute cardiac injury, thus predicting both a severe course of the disease and a poor outcome. Pathogenesis of acute cardiac injury is not yet completely elucidated, though several mechanisms are allegedly involved, such as a direct cardiomyocyte injury, oxygen supply-demand inequity caused by hypoxia, several active myocardial depressant factors during sepsis, and endothelial dysfunction due to the hyperinflammatory status. Moreover, the increased levels of plasma cytokines and catecholamines and a significantly enhanced prothrombotic environment may lead to the destabilization and rupture of atheroma plaques, subsequently triggering an acute coronary syndrome. In the present review, we focus on describing the epidemiology, pathogenesis, and role of biomarkers in the diagnosis and prognosis of patients with acute cardiac injury in the setting of the COVID-19 pandemic. We also explore some novel therapeutic strategies involving immunomodulatory therapy, as well as their role in preventing a severe form of the disease, with both the short-term outcome and the long-term cardiovascular sequelae being equally important in patients with SARS-CoV-2 induced acute cardiac injury.

Prognostic Value of T-wave Positivity in Lead aVR in COVID-19 Pneumonia

OBJECTIVE

T-wave positivity in the lead aVR is a marker of ventricular repolarization abnormality and provides information on short- and long-term cardiovascular mortality in heart failure patients, those with anterior myocardial infarction, and patients who underwent hemodialysis for various reasons. The aim of this study was to investigate the relationship between T-wave positivity in the lead aVR on superficial electrocardiogram and mortality from COVID-19 pneumonia.

METHODS

This study retrospectively included 130 patients who were diagnosed with COVID-19 and treated as an outpatient or in the thoracic diseases ward in a single center between January 2021 and June 2021. All patients included in the study had clinical and radiological features and signs of COVID-19 pneumonia. The COVID-19 diagnosis of all patients was confirmed by polymerase chain reaction detected from an oropharyngeal swab.

RESULTS

A total of 130 patients were included in this study. Patients were divided into two groups: survived and deceased. There were 55 patients (mean age: 64.76-14.93 years, 58.18 male, 41.12% female) in the survived group and 75 patients (mean age: 65-15 years, 58.67 male, 41.33% female) in the deceased group. The univariate and multivariate regression analyses showed that positive transcatheter aortic valve replacement (OR 5.151; 95%CI 1.001-26.504; p=0.0012), lactate dehydrogenase (OR 1.006; 95%CI 1.001-1.010; p=0.012), and d-dimer (OR 1.436; 95%CI 1.115-1.848; p=0.005) were independent risk factors for mortality.

CONCLUSION

A positive transcatheter aortic valve replacement is useful in risk stratification for mortality from COVID-19 pneumonia.

Clinical variants of myocardial involvement in COVID-19-positive patients: a cumulative experience of 2020

Myocardial injury, diagnosed by troponin elevation, is common in COVID-19 patients, but cardiac involvement with clinical manifestations occurs less frequently. We analyzed the literature on COVID-19 (2020) and systematically reviewed the cases where individual patient data were presented. We searched PubMed and Google Scholar for "COVID," "COVID-19," and "coronavirus" in combination with "myocarditis," "heart failure," "takotsubo," "cardiomyopathy," and "cardiogenic shock." We identified 90 cases of COVID-19 with myocardial involvement, mean age 52.9 ± 18.3 years, 54.5% males. Of them, 55 survived (61.1%), 20 died (22.2%), and in 15 (16.7%) the outcome was unknown at the time of publication. Among patients with known outcome, mortality was 26%. The nadir LVEF was 31.7 ± 13.1% and recovered to 50.1 ± 16.0%. Pericardial effusion was a common finding, reported in 21 (23.3%) of patients, including moderate size effusion in 8.9% and large in 7.8%. The effusion caused tamponade in 11 (12.2%) of patients. Out of 83 patients who experienced a decrease in LVEF, 30 could be classified as takotsubo syndrome. The takotsubo patients were older than those with myocarditis, and with relatively high proportion of males. About one third of the cases was complicated by cardiogenic shock. Myocardial involvement in COVID-19 patients most often presents as a new, rapid decrease in LVEF, although normal LVEF or takotsubo-like wall motion pattern does not rule out myocarditis. Moderate and large pericardial effusion is common, and cardiac tamponade occurs in 12.2% of patients. Cardiogenic shock develops in one third of the patients. Mortality appears to be high at 26%.

The Evolving Role of Echocardiography During the Coronavirus Disease 2019 Pandemic

Coronavirus disease 2019 (COVID-19) has been associated with a wide spectrum of cardiovascular manifestations. Since the beginning of the pandemic, echocardiography has served as a valuable tool for triaging, diagnosing and managing patients with COVID-19. More recently, speckle-tracking echocardiography has been shown to be effective in demonstrating subclinical myocardial dysfunction that is often not detected in standard echocardiography. Echocardiographic findings in COVID-19 patients include left or right ventricular dysfunction, including abnormal longitudinal strain and focal wall motion abnormalities, valvular dysfunction and pericardial effusion. Additionally, some of these echocardiographic abnormalities have been shown to correlate with biomarkers and adverse clinical outcomes, suggesting an additional prognostic value of echocardiography. With increasing evidence of cardiac sequelae of COVID-19, the use of echocardiography has expanded to patients with cardiopulmonary symptoms after recovery from initial infection. This article aims to highlight the available echocardiographic tools and to summarize the echocardiographic findings across the full spectrum of COVID-19 disease and their correlations with biomarkers and mortality.

New Perspectives on Long COVID Syndrome: The Development of Unusually Delayed and Recurring Pericarditis After a Primary SARS-CoV-2 Infection

Since the start of the COVID-19 pandemic in early 2020, pericarditis has been identified as a COVID-19 complication. We report a case where the development of pericarditis was unusually delayed after the initial COVID infection. The reported onset of pericarditis and pericardial effusion is anywhere from a few days to a few months after infection. Our case surmises that a latent complication of COVID-19 can manifest more than one year after the initial infection.

A forty-three-year-old male with a past medical history of SARS-CoV-2 infection in September 2020 presented in September 2021 and January 2022 with recurrent sharp chest pain and shortness of breath. During both admissions, he was diagnosed with acute pericarditis, and his workup was significant for elevations in D-dimer and CRP as well as pericardial and pleural effusions.

Recurring pericardial symptoms and persistent elevations in D-dimer and CRP point toward a COVID etiology, particularly in the absence of other factors associated with pericarditis. Our case highlights the importance of recognizing this latent complication one year after the initial infection and how the symptoms can persist beyond the one-year period.

Assessment of COVID-19 deaths from cardiological perspective

BACKGROUND

COVID-19 can cause a variety of cardiac complications and a range of electrocardiographic abnormalities. We analysed cardiological parameters including ECG and high-sensitivity troponin T (hs-TnT) level and their association with mortality in hospitalised patients with COVID-19.

METHODS

We retrospectively analysed the demographics, comorbidities, laboratory findings and electrocardiographic parameters of 453 consecutive patients, whose outcome was clear, died or discharged. Findings were compared between survivors and non-survivors. Also, the same comparison was made between cardiac injury and no-cardiac injury subgroups.

RESULTS

The cardiac injury group had significantly higher in-hospital mortality than the no-cardiac injury group. Also, frequencies of atrial fibrillation, axis change, ST-segment/T-wave change, fragmented QRS, premature atrial/ventricular contraction was found to be higher in the cardiac injury group. Moreover, non-survivors had longer QRS intervals, more frequent ST-segment/T-wave changes and isolated S1Q3T3 pattern than surviving patients. Laboratory results showed median values of hs-TnT at the admission of 4.95 ng/L (IQR, 3-12.35) with concentrations markedly higher in the non-surviving patients vs survivors. Hs-TnT value along with age and respiratory rate was found to be an independent predictor of in-hospital mortality in hospitalised patients with COVID-19. Comorbidities were more frequently reported in non-surviving and cardiac injury groups than those surviving and without cardiac injury.

CONCLUSIONS

In COVID-19 patients, both elevated hs-TnT and ECG abnormalities, suggesting cardiac involvement, on admission portends an ominous prognosis and indicates at higher risk of in-hospital mortality. Prioritised treatment and more aggressive therapeutic strategies could be planned to avoid the occurrence of death in these patients.

Systemic lupus erythematosus after coronavirus disease-2019 (COVID-19) infection: Case-based review

Background

Coronavirus disease-2019 (COVID-19) is a novel infectious disease, which presents with various clinical manifestations. There is growing evidence of an association between COVID-19 infection and autoimmune diseases. The aim of this case report was to demonstrate the association of COVID-19 infection and the development of systemic lupus erythematosus (SLE).

Case presentation

A 38 year old Iranian woman presented with progressive icterus, pleuritic chest pain, palpitation, dyspnea, photosensitivity and arthralgia 18-days after COVID-19 symptoms proved by a positive polymerized chain reaction (PCR). The chest and abdomen computerized tomography (CT) scan showed pericardial and pleural effusion and enlarged liver and abdominal lymph nodes. Antinuclear antibody (ANA), anti-double stranded deoxyribonucleic acid (anti-ds DNA) antibody and perinuclear anti-neutrophil cytoplasmic antibody (P-ANCA) were positive. She was diagnosed as SLE and was successfully treated with prednisolone 30 mg daily, hydroxychloroquine 200 mg daily and azathioprine 150 mg daily and she remarkably improved. Repeated anti-ds DNA antibody was positive. Due to nausea and abdominal discomfort, azathioprine was discontinued and replaced with mycophenolate mofetil 1500 mg daily. In the article, similar cases were presented; the mean interval between COVID symptoms and SLE presentations was 24.86 days. Pulmonary and renal involvements were the most common presentations of SLE triggered by COVID-19. The most frequently reported autoantibody was ANA.

Conclusion

It is necessary to be aware of the development of lupus disease in COVID-19 infected patients, because prompt diagnosis and treatment is very important to improve their outcome.

Cardiac tamponade - an unexpected "long COVID-19" complication

INTRODUCTION

Year 2020 has been a cornerstone in medical research due to the COVID-19 pandemic outbreak. The process of understanding the condition brought to light certain organ involvement like pulmonary or kidney damage or endocrine disbalances, while connection to other types of organ impairment remain unclear. SARS-CoV-2 has previously been incriminated in cardiac involvement, ranging from mild symptoms to more severe occurrences such as myocarditis, arrythmias or heart failure, thus complicating the acute-phase management and worsening patients' prognosis. Despite being reported as an acute manifestation in critical COVID-19, cardiac tamponade seems to also occur as a "long- COVID19" complication. The latter is a distinct yet unclear entity associated with remanent fatigue or cough, but more severe sequelae like vasculitis or polyneuropathy can occsur.

CASE REPORT

We report the case of a 42-year-old patient admitted in the intensive care unit for severe respiratory and renal dysfunction one month after an initial mild episode of COVID-19. RT-PCR for SARS-CoV-2 on admission was negative. Initial imaging through CT and heart ultrasound revealed the presence of pericardial effusion but no signs of tamponade were initially obvious. Twelve hours later, the patient's state deteriorated with cardiocirculatory failure and signs of obstructive shock. Agents responsible for severe acute respiratory infection (SARI) such as influenza A and B, adenovirus, Bordetella pertussis, Mycoplasma pneumoniae, coxsackie virus, Chlamydia pneumoniae or parainfluenza viruses were ruled out. Surprisingly, RT-PCR testing for SARS-CoV-2 came back positive, although the initial test was negative. Repeated imaging confirmed massive circumferential pericardial effusion for which emergency pericardiocentesis was performed. Fluid was an exudate and histopathology reported chronic inflammation. RT-PCR testing for Mycoplasma tuberculosis in the pericardial tissue came back negative.

CONCLUSIONS

The case is to our knowledge among the first to report cardiac tamponade one month after mild COVID-19 infection. The aim of this case report is to raise awareness in the medical community on the possibility of severe complications targeting major organs in the long-COVID-19 phase.

Imaging Findings of COVID-19-Related Cardiovascular Complications

Other than respiratory disease, patients with coronavirus disease 2019 (COVID-19) commonly have cardiovascular manifestations, which are recognized as significant risk factors for increased mortality. COVID-19 patients may present with a wide spectrum of clinical presentations ranging from asymptomatic heart disease detected incidentally by cardiac investigations (troponin, BNP, and imaging) to cardiogenic shock and sudden cardiac death. In this broad clinical course, advanced imaging plays an important role in the diagnosis of different patterns of myocardial injury, risk stratification of COVID-19 patients, and in detecting potential cardiac side effects of the current treatments and vaccines against the severe acute respiratory syndrome.

Coronavirus Disease 2019 (COVID-19) and Severe Pericardial Effusion: From Pathogenesis to Management: A Case Report Based Systematic Review

The Severe acute respiratory syndrome coronavirus-2 (SARS-COV-2) created a global pandemic that continues to this day. In addition to pulmonary symptoms, the virus can have destructive effects on other organs, especially the heart. For example, large pericardial effusion has been observed as a critical and life-threatening finding in Coronavirus disease of 2019 (COVID-19) patients. In this case report based systematic review, we review the reports of moderate to severe pericardial effusion associated with tamponade physiology. Direct cardiomyocyte and pericardium invasion, inflammation and cytokine storms and oxidative stress due to acute respiratory distress syndrome, are the pathogenesis of this phenomenon. The results showed that the manifestations of this finding are variable. Pericardial effusion can be seen as a delayed complication, accompanied by myocarditis or pericarditis, isolated, or with acute respiratory distress syndrome. In most patients, emergency percutaneous pericardiocentesis was performed, and fluid analysis was often exudative in 3 pattern of hemorrhagic, serous, and serosanguinous. Medical treatment and follow-up are recommended, especially in cases of pericarditis.

Myocarditis and pericarditis: Case definition and guidelines for data collection, analysis, and presentation of immunization safety data

Myocarditis and/or pericarditis (also known as myopericarditis) are inflammatory diseases involving the myocardium (with non-ischemic myocyte necrosis) and/or the pericardial sac. Myocarditis/pericarditis (MPC) may present with variable clinical signs, symptoms, etiologies and outcomes, including acute heart failure, sudden death, and chronic dilated cardiomyopathy. Possible undiagnosed and/or subclinical acute myocarditis, with undefined potential for delayed manifestations, presents further challenges for diagnosing an acute disease and may go undetected in the setting of infection as well as adverse drug/vaccine reactions. The most common causes of MPC are viral, with non-infectious, drug/vaccine associated hypersensitivity and/or autoimmune causes being less well defined and with potentially different inflammatory mechanisms and treatment responses. Potential cardiac adverse events following immunization (AEFIs) encompass a larger scope of diagnoses such as triggering or exacerbating ischemic cardiac events, cardiomyopathy with potential heart failure, arrhythmias and sudden death. The current published experience does not support a potential causal association with vaccines based on epidemiologic evidence of relative risk increases compared with background unvaccinated incidence. The only evidence supporting a possible causal association of MPC with a vaccine comes from case reports. Hypersensitivity MPC as a drug/vaccine induced cardiac adverse event has long been a concern for post-licensure safety surveillance, as well as safety data submission for licensure. Other cardiac adverse events, such as dilated cardiomyopathy, were also defined in the CDC definitions for adverse events after smallpox vaccination in 2006. In addition, several groups have attempted to develop and improve the definition and adjudication of post-vaccination cardiovascular events. We developed the current case definitions for myocarditis and pericarditis as an AEFI building on experience and lessons learnt, as well as a comprehensive literature review. Considerations of other etiologies and causal relationships are outside the scope of this document.

Stress-Induced Cardiomyopathy—Considerations for Diagnosis and Management during the COVID-19 Pandemic

The novel coronavirus disease 2019 (COVID-19) is associated with several cardiovascular manifestations including myocardial injury, myocarditis, arrhythmia, and pulmonary embolism. Rare cases of stress-induced cardiomyopathy, or takotsubo syndrome have also been reported during the acute infection, and secondary to stress following lockdown and self-isolation. Diagnosis in the setting of the acute infection is challenging since conventional imaging modalities such as transthoracic echocardiography and coronary angiography should be restricted to minimize physician-patient contact until the patients is tested negative for COVID-19. The use of point of care hand-held ultrasound is appropriate for this purpose. The overall course of the disease seems to be similar to takotsubo in the general population. Physicians should be familiar with the clinical presentation, possible complications, and management of takotsubo during COVID-19 outbreak. Here, we review the special considerations in the diagnosis and management of takotsubo syndrome during the current pandemic.

Case Report: Recurrent pericardial tamponade in a child with COVID-19

BACKGROUND

Pericarditis is rare in Coronavirus disease 2019 (Covid-19) infection and only a few cases were reported in children.

CASE PRESENTATION

We present the case of a 15-year-old boy with symptoms of high fever and worsening chest pain during COVID-19 infection. Chest computer tomography (CT) and echocardiography confirmed pericardial tamponade requiring urgent drainage. Despite antiviral drug treatment, after 18 days severe attack developed requiring repeated pericardiocentesis. High dose ibuprofen, colchicin and the interleukin-1 antagonist, anakinra were given. Clinical symptoms and laboratory parameters improved after seven days of treatment. Autoinflammatory diseases were also suspected in the background the severe pericarditis, but genetic analysis ruled out any mutations.

CONCLUSION

Pericarditis associated with COVID-19 infection may present in the acute phase or later as MIS-C. Though pericardial tamponade related to ongoing Covid-19 infection is rare in children, even biological treatment with interleukin-1 antagonist may be needed to control the inflammation.

[Acute myocardial infarction and cardiogenic shock in patient with COVID-19]

The conditions of the pandemic caused by the novel coronavirus infection (COVID-19) are associated with overloading intensive care units, conversion of hospitals, and changes in routing of patients with acute cardiovascular pathology. At the same time, medical practice is still challenged to provide medical care to patients with acute coronary syndrome (ACS). Patients with COVID-19 and acute myocardial infarction (AMI) are at a higher risk of death while the incidence of this combination of diseases will be growing. This article describes a case of diagnosis and treatment of COVID-19 in a 69-year-old patient who was urgently hospitalized with cardiogenic shock associated with ACS, electrocardiographic signs of complete left bundle branch block, and left ventricular ejection fraction of 19 %. Coronary angiography with stenting was successfully performed in the conditions of extracorporeal membrane oxygenation. The patient received long-term intensive therapy in the intensive care unit followed by symptomatic treatment in the cardiac surgery unit. The patient's condition gradually improved and he was discharged from the hospital on the 56th day. The strategy of intensive care and active follow-up helped saving life of the patient with COVID-19 and AMI.

Cardiac tamponade as a presentation of COVID-19 after cardiac surgery

We present two patients who turned positive for coronavirus disease 2019 (COVID-19) after elective cardiac surgery, developing postoperative pericardial effusion with tamponade. One of the patients who presented with tamponade had no other symptoms of COVID-19 infection. COVID-19 can rarely present with cardiac manifestations including pericardial effusion and tamponade. In the post cardiac surgery setting, this effect of the virus may be accentuated. Hence, a high index of suspicion and prompt management are the keys for a successful outcome.

Myocarditis associated with Covid-19 disease: A systematic review of published case reports and case series

BACKGROUND

Covid-19 is an extremely contagious illness caused by the severe acute respiratory syndrome (SARS-CoV-2) virus. The cardiac involvement in such a public health emergency disease has not been well studied and a conflicting evidence exists on this issue.

OBJECTIVE

This systematic review article aimed to compile and illustrate clinical characteristics, diagnostic findings, management, and outcomes manifesting in myocarditis linked with Covid-19.

METHODS

A literature search was accomplished for published eligible articles with MEDLINE/PubMed and Embase databases. All eligible case reports and case series were included from around the world without any language restrictions. For this review, inclusion criteria were laboratory-confirmed SARS-CoV-2 infection cases reporting a diagnosis of acute myocarditis.

RESULTS

Data from 41 studies describing myocarditis in 42 Covid-19 patients was obtained. The median age of these patients was 43.4 years, with 71.4% of them being men. Fever was the most prevalent presenting symptoms seen in 57% of patients. Hypertension was the most pervasive comorbidity accompanying these patients. Cardiac biomarkers troponin and brain natriuretic peptide (BNP) were raised in almost 90% and 87% of patients, respectively. Electrocardiogram findings were nonspecific and included ST-segment and T-wave changes. Echocardiogram commonly showed left ventricular systolic dysfunction with increased heart size. Cardiac magnetic resonance imaging (CMRI) exhibited myocardial edema and injury. The most prevalent histopathological feature appreciated was diffuse lymphocytic inflammatory infiltrates. Antivirals and corticosteroids were the most frequently used medications. About 38% of patients also needed vasopressor assistance. Out of 42 patients, 67% recovered, and eight died.

CONCLUSION

Because of the risk of a sudden worsening of patients conditions and myocarditis association with considerable mortality and morbidity, a knowledge of this cardiac complication of Covid-19 disease is crucial for healthcare professionals.

Immunologic Dysregulation and Hypercoagulability as a Pathophysiologic Background in COVID-19 Infection and the Immunomodulating Role of Colchicine

In 2020, SARS-COV-2 put health systems under unprecedented resource and manpower pressure leading to significant number of deaths. Expectedly, researchers sought to shed light on the pathophysiologic background of this novel disease (COVID-19) as well as to facilitate the design of effective therapeutic modalities. Indeed, early enough the pivotal role of inflammatory and thrombotic pathways in SARS-COV-2 infection has been illustrated. The purpose of this article is to briefly present the epidemiologic and clinical features of COVID-19, analyze the pathophysiologic importance of immunologic dysregulation and hypercoagulability in developing disease complications and finally to present an up-to-date systematic review of colchicine's immunomodulating capacity in view of hindering coronavirus complications.

Prevalence of abnormal cardiovascular magnetic resonance findings in recovered patients from COVID-19: a systematic review and meta-analysis

BACKGROUND

The prevalence of abnormal cardiovascular magnetic resonance (CMR) findings in recovered coronavirus disease 2019 (COVID-19) patients is unclear. This study aimed to investigate the prevalence of abnormal CMR findings in recovered COVID-19 patients.

METHODS

A systematic literature search was performed to identify studies that report the prevalence of abnormal CMR findings in recovered COVID-19 patients. The number of patients with abnormal CMR findings and diagnosis of myocarditis on CMR (based on the Lake Louise criteria) and each abnormal CMR parameter were extracted. Subgroup analyses were performed according to patient characteristics (athletes vs. non-athletes and normal vs. undetermined cardiac enzyme levels). The pooled prevalence and 95% confidence interval (CI) of each CMR finding were calculated. Study heterogeneity was assessed, and meta-regression analysis was performed to investigate factors associated with heterogeneity.

RESULTS

In total, 890 patients from 16 studies were included in the analysis. The pooled prevalence of one or more abnormal CMR findings in recovered COVID-19 patients was 46.4% (95% CI 43.2%-49.7%). The pooled prevalence of myocarditis and late gadolinium enhancement (LGE) was 14.0% (95% CI 11.6%-16.8%) and 20.5% (95% CI 17.7%-23.6%), respectively. Further, heterogeneity was observed (I2 > 50%, p < 0.1). In the subgroup analysis, the pooled prevalence of abnormal CMR findings and myocarditis was higher in non-athletes than in athletes (62.5% vs. 17.1% and 23.9% vs. 2.5%, respectively). Similarly, the pooled prevalence of abnormal CMR findings and LGE was higher in the undetermined than in the normal cardiac enzyme level subgroup (59.4% vs. 35.9% and 45.5% vs. 8.3%, respectively). Being an athlete was a significant independent factor related to heterogeneity in multivariate meta-regression analysis (p < 0.05).

CONCLUSIONS

Nearly half of recovered COVID-19 patients exhibited one or more abnormal CMR findings. Athletes and patients with normal cardiac enzyme levels showed a lower prevalence of abnormal CMR findings than non-athletes and patients with undetermined cardiac enzyme levels. Trial registration The study protocol was registered in the PROSPERO database (registration number: CRD42020225234).

Echocardiography, lung ultrasound, and cardiac magnetic resonance findings in COVID-19: A systematic review

BACKGROUND

The manifestations of COVID-19 as outlined by imaging modalities such as echocardiography, lung ultrasound (LUS), and cardiac magnetic resonance (CMR) imaging are not fully described.

METHODS

We conducted a systematic review of the current literature and included studies that described cardiovascular manifestations of COVID-19 using echocardiography, CMR, and pulmonary manifestations using LUS. We queried PubMed, EMBASE, and Web of Science for relevant articles. Original studies and case series were included.

RESULTS

This review describes the most common abnormalities encountered on echocardiography, LUS, and CMR in patients infected with COVID-19.

Rheumatological complications of Covid 19

Introduction

COVID-19 has caused unprecedented hardships in the 21st century with more than 150 million infections. Various immunological phenomena have been described during the course of the infection, and this infection has also triggered autoimmunity. Rheumatological illnesses have been described following resolution of the acute infection; hence we sought to conduct a review of the rheumatological complications of COVID-19.

Methods

We conducted a literature search for articles relating to sequelae of COVID-19 from Jan 2020 to 30th April 2021.

Results

We found a number of reports of inflammatory arthritis after SARS-CoV-2 infection. SLE and renal disease have been described, and vasculitis also appears to be a common complication. Rhabdomyolysis and myositis has also been reported in a number of patients. We also found some evidence of large vessel vasculitis in ‘long COVID’ patients.

Conclusions

This review highlights a number of important complications such as inflammatory arthritis, lupus-like disease, myostis and vasculitis following SARS-CoV-2 infection.

Rescue Venoarterial Extracorporeal Membrane Oxygenation After Cardiac Arrest in COVID-19 Myopericarditis: A Case Report

Coronavirus Disease-2019 (COVID-19) has been associated with potentially life threatening cardiovascular complications, including fulminant myocarditis and cardiac tamponade. Optimal management strategies are still unclear, including the role of immunomodulatory therapies and extracorporeal membrane oxygenation (ECMO) in the context of cardiogenic shock. We report a case of a middle-aged female with COVID-19 who developed respiratory distress and hemodynamic deterioration with elevated troponin levels on the seventh day of symptoms. Echocardiography demonstrated pericardial effusion with diastolic restriction of the right ventricle. Cardiac arrest developed during pericardiocentesis, resulting in emergency thoracotomy and pericardial drainage. Venoarterial ECMO was subsequently initiated due to refractory cardiogenic shock. Tocilizumab, immunoglobulin, methylprednisolone and convalescent plasma were added to supportive care, with progressive recovery of cardiac function and successful weaning from mechanical ventilation. This case highlights the potential role of ECMO, convalescent plasma and immunomodulatory therapies in the management of cardiogenic shock associated with COVID-19 myopericarditis.

Cardiogenic shock following cardiac tamponade and Takotsubo in COVID-19

Introduction: Takotsubo is often described as stress-induced cardiomyopathy and is a known cause of heart failure. Objective: Review the clinical course of a young coronavirus disease 2019 (COVID-19) patient who developed Takotsubo following cardiac tamponade. Case presentation: A 42-year-old woman presented to the emergency department with fever, altered mental status and hypoxia. She was ultimately found to be in cardiac tamponade and within 2 hours of a pericardiocentesis she developed Takotsubo and was in cardiogenic shock. Her family decided to place her on comfort measures and she died the same day. Discussion: This case illustrates the increasing number of cardiovascular complications being reported in COVID-19 and highlights the importance of clinicians to be aware of these challenges. Conclusion: Here, we report a distinct presentation of cardiogenic shock in a young COVID-19 patient. The rapid onset of her suspected Takotsubo and the severity of her disease were striking features in this case.

Covid and Cardiovascular Diseases: Direct and Indirect Damages and Future Perspective

SARS-CoV-2 infection determines a disease that predominantly affects lungs. However the cytokines storms, determined by the huge immune response to the infection, could affect also other organs and apparatus such as heart and vessels. Beyond the acute inflammation itself also hypercoagulative status has been linked to SARSCoV-2 infection and this surely relates to the increase seen in prevalence of pulmonary embolism and myocardial infarction. A number of cardiac abnormalities and pathologies have been observed, with special attention to cardiac arrhythmias and myocardial involvement. Furthermore, indirect damages determined by the reduction in acute and chronic cardiovascular care, results in a strong mortality and morbidity outcomes in cardiological patients. In this review we will summarise current knowledge on both direct and indirect cardiovascular damages determined by the SARS-CoV-2 pandemia.

COVID-19 and Cardiomyopathy: A Systematic Review

Background: Cardiomyopathies (CMPs) due to myocytes involvement are among the leading causes of sudden adolescent death and heart failure. During the COVID-19 pandemic, there are limited data available on cardiac complications in patients with COVID-19, leading to severe outcomes.

Methods: We conducted a systematic search in Pubmed/Medline, Web of Science, and Embase databases up to August 2020, for all relevant studies about COVID-19 and CMPs.

Results: A total of 29 articles with a total number of 1460 patients were included. Hypertension, diabetes, obesity, hyperlipidemia, and ischemic heart disease were the most reported comorbidities among patients with COVID-19 and cardiomyopathy. In the laboratory findings, 21.47% of patients had increased levels of troponin. Raised D-dimer levels were also reported in all of the patients. Echocardiographic results revealed mild, moderate, and severe Left Ventricular (LV) dysfunction present in 17.13, 11.87, and 10% of patients, respectively.

Conclusions: Cardiac injury and CMPs were common conditions in patients with COVID-19. Therefore, it is suggested that cardiac damage be considered in managing patients with COVID-19.

Subacute effusive-constrictive pericarditis in a patient with COVID-19

We report the case of a previously healthy young woman, who developed a severe form of COVID-19 with massive pneumonia and acute pericarditis in whom constrictive physiology developed rapidly. To our knowledge, this represents the second reported case of SARS-CoV-2 constrictive pericarditis, a rare, but severe cardiac complication.

The Synergy of ADAM17-Induced Myocardial Inflammation and Metabolic Lipids Dysregulation During Acute Stress: New Pathophysiologic Insights Into Takotsubo Cardiomyopathy

Due to its reversible nature, Takotsubo cardiomyopathy (TTC) is considered an intriguing and fascinating cardiovascular disease characterized by a transient wall motion abnormality of the left ventricle, affecting more than one coronary artery territory, often in a circumferential apical distribution. Takotsubo cardiomyopathy was discovered by a Japanese cardiovascular expert and classified as acquired primary cardiomyopathy by the American Heart Association (AHA) in 1990 and 2006, respectively. Regardless of the extensive research efforts, its pathophysiology is still unclear; therefore, there are no well-established guidelines specifically for treating and managing TTC patients. Increasing evidence suggests that sympatho-adrenergic stimulation is strongly associated with the pathogenesis of this disease. Under acute stressful conditions, the hyperstimulation of beta-adrenergic receptors (β-ARs) resulting from excessive release of catecholamines induces intracellular kinases capable of phosphorylating and activating “A Disintegrin and Metalloprotease 17” (ADAM17), a type-I transmembrane protease that plays a central role in acute myocardial inflammation and metabolic lipids dysregulation which are the main hallmarks of TTC. However, our understanding of this is limited; hence this concise review provides a comprehensive insight into the key role of ADAM17 in acute myocardial inflammation and metabolic lipids dysregulation during acute stress. Also, how the synergy of ADAM17-induced acute inflammation and lipids dysregulation causes TTC is explained. Finally, potential therapeutic targets for TTC are also discussed.

Pericardial Diseases in COVID19: a Contemporary Review

PURPOSE OF REVIEW

Coronavirus disease 2019 (COVID19) involves the heart, including pericardium. This article reviews the possible pathophysiological mechanisms in pericardial involvement in COVID19 and pericardial manifestations of COVID19. It also summarizes the patients with pericarditis secondary to COVID19 and outlines the contemporary treatment strategies in this patient population.

RECENT FINDINGS

A high degree of suspicion is required to identify the pericardial involvement in COVID19 patients. It is proposed that an underlying hyperinflammatory reaction in COVID19 leads to pericardial inflammation. Acute pericarditis with or without myocardial involvement is diagnosed on clinical presentation, serum inflammatory markers, electrocardiogram, and echocardiogram. Multimodality imaging may also have an additional diagnostic value. Patients are usually managed medically, but some patients develop a life-threatening pericardial tamponade necessitating pericardial drainage. Pericardial involvement is an important clinical manifestation of COVID19 requiring a proper workup. Timely diagnosis and a specific management plan based on the presentation and concomitant organ involvement usually lead to a complete recovery.

Cardiac Involvement in COVID-19 Patients: A Contemporary Review

Background: The widely variable clinical manifestations of SARS-CoV2 disease (COVID-19) range from asymptomatic infections to multiple organ failure and death. Among the organs affected is the heart. This does not only affect people who already have previous cardiovascular problems, but also healthy people. This is a reason not to overlook any symptoms or to perform targeted examinations, even if apparently unrelated to the heart, for quick recognition and timely therapy. Aim of the study: This review recapitulates the current state of knowledge on the potential mechanisms and manifestation of myocarditis in patients with COVID-19 infection. Methods: A web-based search of published data was performed for all relevant studies on patients diagnosed with a COVID-19-induced acute myocarditis, and a total of 50 reports were included. The analysis of the studies evaluated highlights a male predominance, with the average age of patients being 55 years. The most common presenting symptoms included fever, shortness of breath, cough, and chest pain. Among ECG changes, non-specific ST-segment and T-wave amplitude alterations and ventricular tachycardia episodes were reported. Finally, we wanted to use a general evaluation without distinguishing between various countries, taking into consideration only the peer or reviewer, regardless of the declared value of the journals that have been published. Results and critical findings: The most common presenting symptoms included fever, shortness of breath, cough, and chest pain. Among ECG changes, non-specific ST-segment and T-wave amplitude alterations and ventricular tachycardia episodes were reported. In most patients, elevated levels of cardiac and inflammatory biomarkers were measured. Left ventricular dysfunction and hypokinesis were commonly exhibited symptoms. Cardiac Magnetic Resonance Imaging (CMRI) confirmed the diagnosis of myocarditis with features of cardiac edema and cardiac injury. Nine patients underwent histopathological examination. Treatment with corticosteroids and immunoglobulins was the most applied strategy following the administration of antivirals. Discussion: Despite the exponentially growing knowledge on the management of COVID-19 infection, current available data on SARS-CoV2-correlated myocarditis are still limited, and several difficulties may be encountered in the differential diagnosis of acute myocarditis in the context of COVID-19 disease. Conclusions: While diagnostic criteria and evaluation strategies for myocarditis are well described, no guidelines for the diagnosis and treatment of myocarditis in COVID-19 patients have yet been established. Therefore, further research is needed to advance the understanding of this disease process and define the most appropriate strategic approach in these patients.
