Abstract
Clozapine is a uniquely effective antipsychotic indicated for treatment-resistant schizophrenia. However, its use is underutilised and often delayed for years due to potential adverse reactions including myocarditis and cardiomyopathy. The purpose of this study was to conduct a retrospective review of the clinical records of patients initiating clozapine in the Auckland District Health Board (ADHB) region to determine the incidence of clozapine-associated myocarditis and cardiomyopathy and to identify potential risk factors associated with these cardiotoxicities. The incidence of clozapine-associated myocarditis and cardiomyopathy over a two-year period in the ADHB region was 3.8% and 1.3% respectively.

Abstract
Recent studies have suggested that malaria may affect the cardiovascular system. The aim of this systematic review and meta-analysis was to determine the prevalence of cardiovascular complications in symptomatic malaria patients. We searched databases such as Pubmed, Embase, Cochrane, and Web of Science (January 1950-April 2020) for studies reporting on cardiovascular complications in adults and children with malaria. Cardiovascular complications were defined as abnormalities in electrocardiogram (ECG), cardiac biomarkers, and echocardiography on admission or during outpatient examination. Studies of patients with known heart disease or cardiovascular evaluation performed after the start of intravenous antimalarial medication were excluded. The study was registered in International Prospective Register of Systematic Reviews (PROSPERO) (No.: CRD42020167672). The literature search yielded 1,243 studies, and a total of 43 studies with symptomatic malaria patients were included. Clinical studies (n = 12 adults; n = 5 children) comprised 3,117 patients, of which a majority had Plasmodium falciparum (n = 15) and were diagnosed with severe malaria (n = 13). In random-effects models of adults, the pooled prevalence estimate for any cardiovascular complication was 7% (95% CI: 5-9). No meta-analysis was conducted in children, but the range of abnormal ECG was 0-8%, cardiac biomarkers 0-57%, and echocardiography 4-9%. We analyzed 33 cases (n = 10 postmortem), in which the most common cardiovascular pathologies were myocarditis and acute coronary syndrome. All histopathological studies found evidence of parasitized red blood cells in the myocardium. Cardiovascular complications are not uncommon in symptomatic adults and children with malaria. Additional studies investigating malaria and cardiovascular disease are encouraged.

Abstract
PURPOSE OF REVIEW The clinical syndrome of coronavirus disease 2019 (COVID-19) has become a global pandemic leading to significant morbidity and mortality. Cardiac dysfunction is commonly seen in these patients, often presenting as clinical heart failure. Accordingly, we aim to provide a comprehensive review on COVID-19 myocarditis and its long-term heart failure sequelae. RECENT FINDINGS Several suspected cases of COVID-19 myocarditis have been reported. It is often not clear if the acute myocardial dysfunction is caused by myocarditis or secondary to generalized inflammatory state of cytokine release or microvascular thrombotic angiopathy. Ischemia may also need to be ruled out. Regardless, myocardial dysfunction in these patients is associated with poor overall prognosis. Laboratory testing, echocardiography, cardiac magnetic resonance imaging, and even endomyocardial biopsy may be needed for timely diagnosis. Several treatment strategies have been described, including both supportive and targeted therapies. SUMMARY COVID-19 can cause a spectrum of ventricular dysfunction ranging from mild disease to fulminant myocarditis with hemodynamic instability. Future research is needed to understand the true prevalence of COVID-19 myocarditis, as well as to better define various diagnostic protocols and treatment strategies.

Abstract
Background In 2017, a diphtheria outbreak occurred in several provinces in Indonesia. The aim of this study was to identify predictors of mortality outcome of pediatric patients with clinical diphtheria. Methods A retrospective cohort study was conducted using patient medical records at five referral hospitals in the Province of Jakarta and one in Tangerang District, Banten Province during January 2017 to 31 August 2018. All children in the age group of 1–18 years old discharged with diagnosis of clinical diphtheria formed the study group. All anonymized patient data were evaluated for demographic issues, clinical features, immunization status, complication, laboratory profiles and outcome. Results A total of 283 patients with clinical diphtheria were included in the study group with case fatality rate of 3.5%. All mortal patients had the complication of myocarditis. Regression analyses revealed factors for predicting mortality. Incomplete primary diphtheria toxoid immunization, stridor, bull neck, leukocytosis ≥15 x109 cells/L and thrombocytopenia ≤150 x109 cells/L in each combination for 2 predictors modeling were correlated with death. Conclusions We report key predictors of mortality in pediatric patients with clinical diphtheria. The presence of these features when admitted to the hospital must be taken into account, because they can lead to fatal outcome.

Abstract
BACKGROUND This study aims to investigate the role of free triiodothyronine (fT3) in predicting poor prognosis of adult patients with acute myocarditis. METHODS A total of 173 consecutive adult patients with acute myocarditis completed thyroid function evaluations. They were divided into two groups according to fT3 levels: low fT3 group (n = 54, fT3 < 3.54 pmol/liter) and normal fT3 group (n = 119, fT3 ≥ 3.54 pmol/liter). The primary endpoint was major adverse cardiac events (MACE). RESULTS During the 3.5 ± 2.8 years follow-up, the rate of MACE was 29.6% versus 3.5% in low fT3 group versus normal fT3 group, respectively (P < 0.0001). Long-term at 8 years MACE-free survival were lower in low fT3 group versus normal fT3 group (52.9% versus 92.3%, log-rank P < 0.0001), respectively. Univariate Cox analysis showed that left ventricular ejection fraction (LVEF) < 50% [hazard ratio (HR) 10.231, 95% confidence interval (CI): 3.418-30.624, P < 0.0001) and low fT3 level (HR 0.360, 95% CI: 0.223-0.582, P < 0.0001) were strongest two predictors of MACE. After adjustment for traditional risk predictors, the prognostic value of fT3 status was still significant (HR 0.540, 95% CI: 0.316-0.922, P = 0.024). Compared with normal fT3 group, those in low fT3 group were at a much higher risk of MACE (HR 5.074, 95% CI: 1.518-16.964, P = 0.008). CONCLUSIONS Low T3 syndrome was a strong predictor of poor prognosis in adult patients with acute myocarditis. These findings suggest that fT3 level could serve as a biomarker for risk stratification in acute myocarditis patients.

Abstract
BACKGROUND COVID-19 was initially considered to be a respiratory illness, but current findings suggest that SARS-CoV-2 is increasingly expressed in cardiac myocytes as well. COVID-19 may lead to cardiovascular injuries, resulting in myocarditis, with inflammation of the heart muscle. OBJECTIVE This systematic review collates current evidence about demographics, symptomatology, diagnostic, and clinical outcomes of COVID-19 infected patients with myocarditis. METHODS In accordance with PRISMA 2020 guidelines, a systematic search was conducted using PubMed, Cochrane Central, Web of Science and Google Scholar until August, 2021. A combination of the following keywords was used: SARS-CoV-2, COVID-19, myocarditis. Cohorts and case reports that comprised of patients with confirmed myocarditis due to COVID-19 infection, aged >18 years were included. The findings were tabulated and subsequently synthesized. RESULTS In total, 54 case reports and 5 cohorts were identified comprising 215 patients. Hypertension (51.7%), diabetes mellitus type 2 (46.4%), cardiac comorbidities (14.6%) were the 3 most reported comorbidities. Majority of the patients presented with cough (61.9%), fever (60.4%), shortness of breath (53.2%), and chest pain (43.9%). Inflammatory markers were raised in 97.8% patients, whereas cardiac markers were elevated in 94.8% of the included patients. On noting radiographic findings, cardiomegaly (32.5%) was the most common finding. Electrocardiography testing obtained ST segment elevation among 44.8% patients and T wave inversion in 7.3% of the sample. Cardiovascular magnetic resonance imaging yielded 83.3% patients with myocardial edema, with late gadolinium enhancement in 63.9% patients. In hospital management consisted of azithromycin (25.5%), methylprednisolone/steroids (8.5%), and other standard care treatments for COVID-19. The most common in-hospital complication included acute respiratory distress syndrome (66.4%) and cardiogenic shock (14%). On last follow up, 64.7% of the patients survived, whereas 31.8% patients did not survive, and 3.5% were in the critical care unit. CONCLUSION It is essential to demarcate COVID-19 infection and myocarditis presentations due to the heightened risk of death among patients contracting both myocardial inflammation and ARDS. With a multitude of diagnostic and treatment options available for COVID-19 and myocarditis, patients that are under high risk of suspicion for COVID-19 induced myocarditis must be appropriately diagnosed and treated to curb co-infections.

Abstract
ABSTRACT Pediatric inflammatory multisystem syndrome temporally associated with severe acute respiratory syndrome coronavirus 2 (PIMS-TS) is infrequent, but children might present as a life-threatening disease. In a systematic quantitative review, we analyzed 11 studies of PIMS-TS, including 468 children reported before July 1, 2020. We found a myriad of clinical features, but we were able to describe common characteristics: previously healthy school-aged children, persistent fever and gastrointestinal symptoms, lymphopenia, and high inflammatory markers. Clinical syndromes such as myocarditis and Kawasaki disease were present in only one third of cases each one. Pediatric intensive care unit admission was frequent, although length of stay was less than 1 week, and mortality was low. Most patients received immunoglobulin or steroids, although the level of evidence for that treatment is low. The PIMS-ST was recently described, and the detailed quantitative pooled data will increase clinicians' awareness, improve diagnosis, and promptly start treatment. This analysis also highlights the necessity of future collaborative studies, given the heterogeneous nature of the PIMS-TS.

Abstract
Myocarditis is an inflammatory disease of the myocardium with high morbidity and mortality; however, definite prognostic factors are still unclear. Therefore, we aimed to evaluate the predictor of clinical outcomes of acute myocarditis focusing on electrocardiographic findings. The overall result of the study consists of a total of 51 patients demonstrated that wide QRS duration is a meaningful factor for predicting the fulminant course of acute myocarditis. This finding may encourage timely mechanical support resulting in better clinical outcomes.

Abstract
AIMS To determine the frequency and pattern of cardiac complications in patients hospitalised with coronavirus disease (COVID-19). METHODS AND RESULTS CAPACITY-COVID is an international patient registry established to determine the role of cardiovascular disease in the COVID-19 pandemic. In this registry, data generated during routine clinical practice are collected in a standardised manner for patients with a (highly suspected) severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection requiring hospitalisation. For the current analysis, consecutive patients with laboratory confirmed COVID-19 registered between 28 March and 3 July 2020 were included. Patients were followed for the occurrence of cardiac complications and pulmonary embolism from admission to discharge. In total, 3011 patients were included, of which 1890 (62.8%) were men. The median age was 67 years (interquartile range 56-76); 937 (31.0%) patients had a history of cardiac disease, with pre-existent coronary artery disease being most common (n=463, 15.4%). During hospitalisation, 595 (19.8%) patients died, including 16 patients (2.7%) with cardiac causes. Cardiac complications were diagnosed in 349 (11.6%) patients, with atrial fibrillation (n=142, 4.7%) being most common. The incidence of other cardiac complications was 1.8% for heart failure (n=55), 0.5% for acute coronary syndrome (n=15), 0.5% for ventricular arrhythmia (n=14), 0.1% for bacterial endocarditis (n=4) and myocarditis (n=3), respectively, and 0.03% for pericarditis (n=1). Pulmonary embolism was diagnosed in 198 (6.6%) patients. CONCLUSION This large study among 3011 hospitalised patients with COVID-19 shows that the incidence of cardiac complications during hospital admission is low, despite a frequent history of cardiovascular disease. Long-term cardiac outcomes and the role of pre-existing cardiovascular disease in COVID-19 outcome warrants further investigation.

Abstract
The influence of checkpoint inhibitors on the balance between activation and inhibition of T-lymphocytes is strong. The development of checkpoint inhibitors has led to treatments for many malignancies but has also facilitated auto-immune disease. These immunotherapeutic agents could exacerbate already present autoimmune disease or could cause new complications in patients with no prior history of autoimmunity. Monoclonal antibodies targeting immune check points, namely anti-CTLA4 or anti-PD-1/PD-L1, are generally well tolerated; however, treatment with these drugs is associated with a variety of adverse events, such as cardiotoxicity, among others. The main mechanism of cardiac damage is lymphocytic myocarditis, which can consequently cause many symptoms of cardiovascular disease - from asymptomatic elevation of cardiac markers, heart failure, and arrhythmias to cardiogenic shock. Other adverse events include pericardium damage or Tako-tsubo cardiomyopathy. The author declares she has no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers.

Abstract
Toxoplasmosis is a common disease caused by Toxoplasma gondii, a parasite with high prevalence in tropical regions. Most infections show minimal symptoms, but immunocompromised patients tend to have a poor prognosis. Cardiovascular manifestations in toxoplasmosis are rare and reported in a limited number of patients. As part of the "Neglected Tropical Diseases and Other Infectious Diseases Affecting the Heart" (NET-Heart) project, this paper aims to systematically review all available information regarding the cardiovascular implications of toxoplasmosis. Relevant studies were identified in the MEDLINE and/or PubMed database, and 48 articles were ultimately included. This was completed according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Cardiac compromise in toxoplasmosis mainly involves myocarditis, and complications vary widely in severity. Toxoplasmic myocarditis is challenging to diagnose, as endomyocardial biopsy is usually required. This article provides a summary of cardiac toxoplasmosis, including an original algorithm facilitating diagnosis and treatment.

Abstract
Myocarditis is an inflammatory disease of the heart that may occur because of infections, immune system activation, or exposure to drugs. The diagnosis of myocarditis has changed due to the introduction of cardiac magnetic resonance imaging. We present an expert consensus document aimed to summarize the common terminology related to myocarditis meanwhile highlighting some areas of controversies and uncertainties and the unmet clinical needs. In fact, controversies persist regarding mechanisms that determine the transition from the initial trigger to myocardial inflammation and from acute myocardial damage to chronic ventricular dysfunction. It is still uncertain which viruses (besides enteroviruses) cause direct tissue damage, act as triggers for immune-mediated damage, or both. Regarding terminology, myocarditis can be characterized according to etiology, phase, and severity of the disease, predominant symptoms, and pathological findings. Clinically, acute myocarditis (AM) implies a short time elapsed from the onset of symptoms and diagnosis (generally <1 month). In contrast, chronic inflammatory cardiomyopathy indicates myocardial inflammation with established dilated cardiomyopathy or hypokinetic nondilated phenotype, which in the advanced stages evolves into fibrosis without detectable inflammation. Suggested diagnostic and treatment recommendations for AM and chronic inflammatory cardiomyopathy are mainly based on expert opinion given the lack of well-designed contemporary clinical studies in the field. We will provide a shared and practical approach to patient diagnosis and management, underlying differences between the European and US scientific statements on this topic. We explain the role of histology that defines subtypes of myocarditis and its prognostic and therapeutic implications.

Abstract
We aimed to characterize the epidemiology, diagnostic peculiarities and outcome determinants of bacterial myocarditis. Two cases from our institution and literature reports were collected ending up with a total of 66 cases. In 37 (56%) patients, the diagnosis was confirmed by magnetic resonance and histopathological criteria. The other patients were classified as having possible myocarditis. Only occurrence of rhythm disturbances was associated with the specific diagnosis of myocarditis (p = 0.04). Thirty-two (48%) patients presented with severe sepsis that was associated with a worse prognosis. At multivariate analysis, left ventricular ejection fraction (LVEF) at admission and heart rhythm disturbances were associated with incomplete recovery (odds ratio (OR) 1.1, 95% (CI) 1.03–1.2, p = 0.004 and OR 6.6, 95% CI 1.35–32.5, p = 0.02, respectively). In summary, bacterial myocarditis is uncommon. Most commonly, it is secondary to septic dissemination of bacteria or to transient secondary myocardial toxicity.

Abstract
Since early 2020, the world has been facing a pandemic caused by the novel coronavirus SARS-CoV-2. Although this positive single-stranded RNA virus primarily causes pulmonary infection and failure, it has been associated with multiple cardiovascular diseases including troponin elevation, myocarditis, and cardiac arrhythmias. Cardiac patients are susceptible to developing more severe infection from SARS-COV-2, making management complicated. In this review we discuss the cardiac manifestations of COVID-19 infections as well as considerations for the management of primary cardiac pathologies during this pandemic.

Abstract
Fulminant myocarditis (FM) is an uncommon syndrome characterized by sudden and severe diffuse cardiac inflammation often leading to death resulting from cardiogenic shock, ventricular arrhythmias, or multiorgan system failure. Historically, FM was almost exclusively diagnosed at autopsy. By definition, all patients with FM will need some form of inotropic or mechanical circulatory support to maintain end-organ perfusion until transplantation or recovery. Specific subtypes of FM may respond to immunomodulatory therapy in addition to guideline-directed medical care. Despite the increasing availability of circulatory support, orthotopic heart transplantation, and disease-specific treatments, patients with FM experience significant morbidity and mortality as a result of a delay in diagnosis and initiation of circulatory support and lack of appropriately trained specialists to manage the condition. This scientific statement outlines the resources necessary to manage the spectrum of FM, including extracorporeal life support, percutaneous and durable ventricular assist devices, transplantation capabilities, and specialists in advanced heart failure, cardiothoracic surgery, cardiac pathology, immunology, and infectious disease. Education of frontline providers who are most likely to encounter FM first is essential to increase timely access to appropriately resourced facilities, to prevent multiorgan system failure, and to tailor disease-specific therapy as early as possible in the disease process.

Abstract
Fulminant myocarditis (FM) is a rare, distinct form of myocarditis that has been difficult to classify. Since 1991, the definition of FM has evolved, and it is currently considered an acute illness with hemodynamic derangement and arrhythmias due to a severe inflammatory process requiring support of cardiac pump function and/or urgent management of serious arrhythmias. Diagnosis is aided through use of biomarkers and cardiac imaging, but endocardial biopsy remains the gold standard. Recent evidence has revealed that patients with FM are significantly more likely to die or require heart transplantation than those with the nonfulminant form, refuting previous studies proposing a paradoxically low mortality in patients with FM. Acute hemodynamic derangement is managed by intensive contemporary pharmacologic and interventional approaches, whereas the role of immunosuppressive therapy has not been clarified. Early recognition and aggressive management are essential for favorable outcomes. In conclusion, FM is an inflammatory process requiring intensive support, and it causes a higher morbidity and mortality than acute nonfulminant myocarditis.

Carditis in Acute Rheumatic Fever in a High-Income and Moderate-Risk Country. J Pediatr 2019; 215:187-191.

Abstract
OBJECTIVE To describe clinical presentation, electrocardiographic, and echocardiographic characteristics of carditis at the time of diagnosis of acute rheumatic fever (ARF) over a 13-year period. STUDY DESIGN A single-center retrospective chart analysis was conducted involving all consecutive patients diagnosed with ARF between 2003 and 2015. Patient age, sex, clinical characteristics, recent medical history for group A streptococcal pharyngotonsillitis and antibiotic treatment, and laboratory, echocardiographic, and electrocardiographic findings were recorded. RESULTS Of 98 patients (62 boys, mean age 8.81 ± 3.04 years), 59 (60.2%) reported a positive history of pharyngotonsillitis; 48 (49%) had received antibiotic (mean duration of treatment of 5.9 ± 3.1 days), and, among these, 28 (58.3%) had carditis. Carditis was the second most frequent finding, subclinical in 27% of patients. Mitral regurgitation was present in 49 of 56 patients (87.5%) and aortic regurgitation in 36/56 (64.3%) no stenosis was documented. CONCLUSIONS ARF is still present in high-income countries and can develop despite primary prophylaxis, especially when given for a short course. Our findings highlight the need for 10 days of antistreptococcal treatment to prevent ARF. Echocardiography is important because 27% of cases with carditis were subclinical.

Abstract
Background The predictive value of adiposity indices and the newly developed index for cardiometabolic risk factors and cardiovascular diseases (CVDs) remains unclear in the Chinese population. This study aimed to compare the predictive value of A Body Shape Index with other 5 conventional obesity-related anthropometric indices (body mass index, waist circumference, hip circumference, waist-to-hip ratio, waist-to-height ratio) in Chinese population. Methods and Results A total of 44 048 participants in the study were derived from the baseline data of the PURE-China (Prospective Urban and Rural Epidemiology) study in China. All participants' anthropometric parameters, CVDs, and risk factors (dyslipidemia, abnormal blood pressure, and hyperglycemia) were collected by standard procedures. Multivariable logistic regression models and receiver operator characteristic curve analysis were used to evaluate the predictive values of obesity-related anthropometric indices to the cardiometabolic risk factors and CVDs. A positive association was observed between each anthropometric index and cardiometabolic risk factors and CVDs in all models (P<0.001). Compared with other anthropometric indices (body mass index, waist circumference, hip circumference, waist-to-hip ratio, and A Body Shape Index), waist-to-height ratio had significantly higher areas under the curve (AUCs) for predicting dyslipidemia (AUCs: 0.646, sensitivity: 65%, specificity: 44%), hyperglycemia (AUCs: 0.595, sensitivity: 60%, specificity: 45%), and CVDs (AUCs: 0.619, sensitivity: 59%, specificity: 41%). Waist circumference showed the best prediction for abnormal blood pressure (AUCs: 0.671, sensitivity: 66%, specificity: 40%) compared with other anthropometric indices. However, the new body shape index did not show a better prediction to either cardiometabolic risk factors or CVDs than that of any other traditional obesity-related indices. Conclusions Waist-to-height ratio appeared to be the best indicator for dyslipidemia, hyperglycemia, and CVDs, while waist circumference had a better prediction for abnormal blood pressure.

Abstract
Lymphocytic myocarditis is an inflammatory disease of the heart that may present in a myriad of fashions ranging from mild febrile illness to florid myocarditis and cardiogenic shock. Given its nonspecific clinical presentation, the diagnosis of lymphocytic myocarditis is often challenging. The authors describe four cases of lymphocytic myocarditis in young women who presented with cardiogenic shock. Two patients survived and two died. This presentation has not been seen previously in Hawai'i and the public awareness of this condition is critical. Early diagnosis and the prompt initiation of biventricular mechanical circulatory support appear to have been critical in improving patient survival.
