Essential Cardiology

Coronavirus disease COVID has affected patients across all age groups, with a wide range of illness severity from asymptomatic carriers to severe multi-organ dysfunction and death.

Although early reports have shown that younger age groups experience less severe disease than older adults, our understanding of this phenomenon is in continuous evolution. Children with MIS-C may demonstrate signs and symptoms of Kawasaki disease, but also have some distinct differences. These children have more frequent and severe gastrointestinal symptoms and are more likely to present with a shock-like presentation. Moreover, they often present with cardiovascular involvement including myocardial dysfunction, valvulitis, and coronary artery dilation or aneurysms.

Here, we present a review of the literature and summary of our current understanding of cardiovascular involvement in children with COVID or MIS-C and identifying the role of a pediatric cardiologist in caring for these patients.

COVID has created unprecedented challenges from public health, economic, medical, and research standpoints. It has been reported across all age groups and leading to a wide spectrum of illness severity from asymptomatic carriers to severe multi-organ dysfunction and death.

Rarely, children with active or recent infection with SARS-CoV-2 can also present with a severe inflammatory syndrome and features similar to those encountered in Kawasaki disease [ 8 — 11 ]. In Bergamo province of Italy, a fold increase in the incidence of Kawasaki-like disease in comparison to the last five years has been described [ 8 ]. As of May , the New York State Department of Health has also identified over children with similar presentations [ 12 ].

This novel presentation has been termed as multisystem inflammatory syndrome in children MIS-C [ 12 , 13 ], or pediatric multisystem inflammatory syndrome PMIS [ 14 ] or pediatric inflammatory multisystem syndrome PIMS [ 15 ]—these terms are used interchangeably in this article. With an evolving understanding of this disease and rapidly expanding literature, keeping up with the clinically relevant information is important to our patients and us as clinicians.

Generally cases are classified as suspect, probable or confirmed based on the presence of acute respiratory symptoms, exposure and travel history in addition to confirmatory COVID testing. Severe acute respiratory illness requiring hospitalization in the absence of alternative diagnosis. This initial classification was able to identify all the pediatric patients within a critical spectrum of the disease that often required intensive care. Nevertheless, a less severe expression of the disease was also being seen and soon after, the WHO provided a more inclusive definition recognizing additional patients who did not require escalation of care.

The percentage of children affected by COVID is much lower than adults and they tend to have milder symptoms and significantly lower morbidity and mortality [ 2 — 7 , 14 , 19 , 20 ]. Some of the frequently reported cardiac manifestations of COVID in adults include; myocardial injury, myocardial dysfunction, myocardial infarction, Takotsubo cardiomyopathy, cardiogenic shock, pericardial effusion, arrhythmias, and conduction abnormalities, but these manifestations are quite rare in pediatric patients [ 21 — 27 ].

The cardiac findings encountered to date in the pediatric population include myocarditis, myocardial dysfunction and coronary artery involvement in MIS-C [ 8 , 10 , 12 , 28 — 31 ]. In adults patients, comorbidities such as hypertension, diabetes, and obesity may predispose them to more severe manifestations of the disease [ 4 , 32 , 33 ]. Chinese data: Case fatality 2. Chinese data: 1 death [ 36 ]. Italian data: No deaths [ 5 ]. A thorough history and physical examination is crucial in the diagnosis and assessment of a suspected COVID patient.

A detailed history of comorbid conditions, history of exposure to confirmed or probable cases of COVID and travel history should be obtained. The most commonly reported symptoms in children are fever and cough [ 5 , 34 — 40 ].

Some children present with gastrointestinal GI symptoms including nausea, vomiting, diarrhea or abdominal pain [ 34 , 41 — 43 ]. Other reported symptoms in adults include temporary loss of smell anosmia or taste ageusia sensation, headaches and thromboembolic phenomena [ 32 , 33 , 46 — 48 ].

In children with MIS-C, there is multisystem organ involvement including cardiac, renal, hematological, or neurological manifestations [ 8 , 10 , 12 , 17 , 31 ].

Severe respiratory symptoms are relatively rare in MIS-C [ 50 ]. Signs of heart failure such as edema, organomegaly, murmur, gallop or friction rub maybe present.

It is essential to pay attention to the vital signs and hydration status of patients. However, MIS-C is still a rare phenomenon and other sources of infection that may cause fever or systemic inflammation should also be considered in differential diagnosis.

There are two categories of tests currently being utilized for the diagnosis of COVID infection, diagnostic tests for identifying active infection and serologic tests to identify past infection.

Detection of viral RNA by RT-PCR, from nasopharyngeal swab or other upper respiratory tract specimens, is the most commonly used and reliable test [ 53 ]. Although RT-PCR is highly specific for the virus, negative tests should be interpreted with caution as the specificity of the test depends on the type of assay, site and quality of specimen obtained in addition to the timeline of illness at the time of testing [ 53 , 54 ].

Rapid antigen tests are also available for the diagnosis of active infection but are less commonly used. Serologic tests demand careful interpretation based on timeline of infection [ 53 ]. Common laboratory findings in hospitalized adult patients with COVID include lymphopenia, neutrophilia, and elevations of serum amino-transaminases, lactate dehydrogenase LDH , creatine kinase CK and other inflammatory markers such as C-reactive protein CRP , procalcitonin, ferritin and erythrocyte sedimentation rate ESR [ 32 , 38 , 39 ].

These laboratory abnormalities have also been reported in children, but data are limited due to a relative lack of studies focused on the pediatric population [ 61 , 62 ]. Children presenting with MIS-C consistently demonstrate these laboratory abnormalities including elevated Troponin and BNP levels [ 8 , 10 , 12 , 15 , 17 , 50 ].

Additionally thrombocytopenia, elevated D-dimer, elevated fibrinogen and hypoalbuminemia may be seen [ 8 — 10 , 15 , 50 ]. A direct correlation between CRP and troponin levels has been shown suggesting an additional inflammatory role in the pathogenesis of the clinical manifestations [ 60 ]. Downregulation of the myocardial protective enzyme angiotensin converting enzyme 2 ACE-2 by SARS-CoV-2 has also been proposed as a potential mechanism of injury to the myocardium [ 64 ].

The mechanism of coronary artery dilation may be extrapolated from Kawasaki disease and inlammatory vasculopathy [ 65 ]. Myocardial dysfunction, coronary artery involvement, and factors like hypoxia, electrolyte abnormalities, QT prolonging medications may predispose these patients to various arrhythmias [ 66 , 67 ].

Presence of chest pain, palpitations, persistent tachycardia, tachypnea, or new murmurs should prompt further evaluation by laboratory testing, electrocardiogram ECG or echocardiogram.

An ECG may be considered in patients with concerning cardiac symptoms, elevated cardiac biomarkers, or prior to initiation of any therapy that could prolong the QT interval.

Patients affected with COVID or MIS-C may be predisposed to various arrhythmias or electrocardiographic ECG abnormalities, not only from the disease itself but also from the arrhythmogenic potential of pharmacotherapies. In adults, a higher prevalence of both atrial [ 38 ] and ventricular arrhythmias [ 59 ] were noted among hospitalized patients with COVID which has been linked to an increased risk of in-hospital death [ 59 ]. In patients with myocardial dysfunction, diffuse ST segment changes, T wave inversions in lateral leads, low-voltage QRS, atrioventricular conduction block and sinus node dysfunction has been reported [ 26 , 70 — 74 ].

Premature ventricular contractions [ 30 ], monomorphic [ 74 ] or polymorphic ventricular tachycardia VT [ 50 ] have also been reported. QT prolongation can be seen in critically ill patients with systemic inflammation, fever, electrolyte abnormalities or hypoxia. In addition pharmacotherapies for COVID such as hydroxychloroquine and azithromycin may cause fatal arrhythmias due to QT prolongation [ 75 — 77 ]. Unmasking of Brugada pattern in patients with underlying Brugada syndrome in setting of fever.

There may be global or segmental mild to severe myocardial dysfunction involving the left ventricle in isolation or both ventricles [ 22 , 23 ]. Left ventricular apical ballooning and dysfunction consistent with Takotsubo cardiomyopathy [ 27 , 84 ] as well as pericardial effusions have been reported [ 22 , 23 ].

In the pediatric population, data are lacking regarding echocardiographic findings during the acute infection likely due to the decreased incidence of clinically severe illness compared with adults [ 3 , 34 , 37 ]. However, echocardiographic information is available for pediatric patients with MIS-C. The initial alert to the international community first identifying MIS-C described myocarditis, valvulitis, pericardial effusion, and coronary artery dilation as features of the disease [ 14 ].

Only 1 child had severely dilated coronaries and 1 had peri-coronary echogenicity [ 9 ]. Subsequently, Belhhadjer et al. One of these patients had localized akinesis of the apical segment consistent with Takotsubo cardiomyopathy. Verdoni et al. Most recently, Whittaker et al. Of these eight, five had shock alone, one with fever and inflammation, and two with some mucocutaneous features of Kawasaki disease.

It is important that the individual performing the echo have the skills to obtain all the necessary images in a time efficient manner to limit exposure. The optimal interval between echocardiographic assessments remains to be determined. Primarily, a change in clinical status should guide the echocardiographic evaluation in individual cases. For patients requiring ICU management , daily echocardiograms may be warranted given the potential for rapid changes.

Serial echocardiographic assessment of the coronary arteries for evolving dilation or development of coronary aneurysms is important as well, as this will impact decisions regarding immunomodulatory therapies and anti-thrombotic regimens.

Previously published guidelines for optimal coronary artery imaging in Kawasaki Disease can be utilized [ 65 , 86 ]. For patients with severe ventricular dysfunction or severe coronary dilation, serial assessment for thrombus is important. All MIS-C or Kawasaki disease spectrum type patients should have a follow-up with a pediatric cardiologist with an echocardiogram. Timing of follow-up and imaging tests will depend upon the clinical course, as well as the type and severity of cardiac involvement.

Long term outcomes of children with MIS-C are unknown. Patients with continued coronary artery abnormalities or depressed ventricular function should continue to follow with a pediatric cardiologist while these sequelae of MIS-C are present.

Given the unknowns, even those with recovery of ventricular function or resolution of coronary dilation likely warrant continued follow-up over time. Advanced cardiac imaging with computed tomographic angiography CTA may be necessary for demonstration of coronary arteries in older children and adolescents if poor acoustic windows limit echocardiographic assessment.

Similar to Kawasaki disease, CTA also plays an important role in assessing distal vessels for evidence of dilation [ 65 ]. CTA is also critical in the evaluation of suspected coronary thrombus.

Data regarding the use of cardiac magnetic resonance CMR imaging in the pediatric age group with COVID are lacking although utilization of CMR imaging can be guided by previous evidence from viral myocarditis.

Decisions should be made on case by case basis in consideration with the pediatric cardiologist. In the adult population, the utility of CMR has been described in a case report of myocarditis due to COVID, where it was used to confirm the diagnosis and to demonstrate the extent and severity of myocardial edema [ 30 ]. Therefore until more evidence is available; therapies such as remdesivir and hydroxychloroquine should be used in context of a clinical trial while weighing the risks and benefits of the therapy [ 16 ].

These decisions are individualized to every patient keeping in consideration the various risk factors including young age, immunocompromised status, underlying cardiac or pulmonary disease, obesity or diabetes [ 16 ]. Supplemental oxygen, non-invasive or invasive mechanical ventilation may be needed for patients as appropriate. Antiviral therapies are to be used in the settings of a clinical trial in discussion with an infectious disease team. Given multisystem involvement, patients may benefit from care by a multidisciplinary team of specialists.

Sequential laboratory markers of inflammation, coagulation studies, liver function tests and cardiac biomarkers may be warranted in hospitalized patients. Additional management, as appropriate, is as per the intensivist or hospitalist based on the clinical presentation.

Care should be taken while sedating or intubating patients with severely depressed ventricular function. Consideration for therapies such as IVIG, steroids or biological agents in the setting of a multidisciplinary team discussion regarding current evidence and best practices, risks and benefits.

Aggressive fever reduction with acetaminophen is necessary for patients with Brugada syndrome. Aggressive electrolyte correction is necessary for patients with inherited arrhythmias and channelopathies. Anticoagulation guided by Kawasaki guidelines can be utilized based on degree of coronary artery involvement. Pediatric cardiology follow-up and serial echocardiographic assessment is critically important for patients with coronary artery dilation due to MIS-C.

Although myocardial dysfunction is uncommon among children with typical COVID infection; children presenting with MIS-C may have significant myocardial involvement [ 8 — 10 , 50 ].

Principles and Practice

 Нет! - рявкнула.  - Пойду я! - Ее тон говорил о том, что возражений она не потерпит. Стратмор закрыл лицо руками. - Хорошо. Это на нижнем этаже. Возле фреоновых помп.

Слева и справа от алтаря в поперечном нефе расположены исповедальни, священные надгробия и дополнительные места для прихожан. Беккер оказался в центре длинной скамьи в задней части собора. Над головой, в головокружительном пустом пространстве, на потрепанной веревке раскачивалась серебряная курильница размером с холодильник, описывая громадную дугу и источая едва уловимый аромат.

 Как вы думаете, мисс Флетчер.

 Вы этого не сделаете, - как ни в чем не бывало сказал Хейл.  - Вызов агентов безопасности разрушит все ваши планы. Я им все расскажу.  - Хейл выдержал паузу.  - Выпустите меня, и я слова не скажу про Цифровую крепость.

Кроме того, оказавшись на улице без заложницы, он обречен. Даже его безукоризненный лотос беспомощен перед эскадрильей вертолетов Агентства национальной безопасности. Сьюзан - это единственное, что не позволит Стратмору меня уничтожить.

Конечно. Хейл продолжал взывать к ней: - Я отключил Следопыта, подумав, что ты за мной шпионишь. Заподозрила, что с терминала Стратмора скачивается информация, и вот-вот выйдешь на. Правдоподобно, но маловероятно. - Зачем же ты убил Чатрукьяна? - бросила .

Кроме тридцати футов ого стола красного дерева с буквами АНБ в центре столешницы, выложенной из черных пластинок вишневого и орехового дерева, комнату украшали три акварели Мариона Пайка, ваза с листьями папоротника, мраморная барная стойка и, разумеется, бачок для охлаждения воды фирмы Спарклетс. Мидж налила себе стакан воды, надеясь, что это поможет ей успокоиться. Делая маленькие глотки, она смотрела в окно.

Интуиция подсказывала ему, что в глубинах дешифровального чудовища происходит что-то необычное.
