ABSTRACT
Background and Aim: Cardiovascular manifestations are common (35-100%) in multisystem inflammatory syndrome in children (MIS-C), including ventricular dysfunction, shock, coronary artery dilation, pericardial effusion and conduction abnormalities. Our study aimed to analyse cardiovascular involvement in our patients with MIS-C treated in our hospital. Method(s): The retrospective cohort study included all patients with MIS-C treated from April 2020 to December 2021 in the Mother and Child Health Institute of Serbia. In every case, cardiovascular manifestations were analysed: ventricular dysfunction, coronary artery dilatation, pericardial effusion, shock and ECG changes. Result(s): The study included 77 patients, 45 boys and 32 girls, aver-age years of age 9.3 +/- 4.8. Elevated cardiac troponin I and pro-BNP were observed in 35.9% and 87.8% of patients, respectively. Myocardial dysfunction was observed in half of our patients (50.6%), with an average ejection fraction of 50.5 +/- 8.9%. Children older than 10 years had 4 times higher chances for myo-cardial dysfunction (OR 4.3, 95%CI 1.6-10.8;p = 0.003). Shock syndrome had 21.1% of children on admission, while 5.3% devel-oped shock during the in-hospital stay. Transient coronary artery (CA) dilatation was observed in 6.5% of patients;left CA in 3 pts (Z score +2,95 +/- 0.3), right CA in one patient (Z score +2), and in one LCA and RCA (RCA Z score 2.6). Transient CA dilatations were observed only in patients with KD-like clinical presentation (5/54 pts). Mild pericardial effusion with spontaneous resolution was detected in 28.6% of children, while one female adolescent had severe pericardial effusion with threatening cardiac tamponade. On the standard ECG, 53% of children had negative T wave in inferior or/and precordial leads averagely on day 2 (IQR 1-3 day);transient QTc prolongation was registered in 46% of patients, averagely on day 7 (IQR 5-9). Sinus bradycardia and coronary rhythm were registered in 42.1% of patients, while premature ven-tricular beats were observed in 2.7% of pts. left ventricle thrombus was detected in one patient with normal echocardiography find-ing. In this patient, increased activity of Factor VIII and XII was proven. Conclusion(s): Cardiac manifestations are common and potentially life-threatening in MIS-C and should be assessed for at presenta-tion and during the clinical course as indicated.
ABSTRACT
The problem of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) remains highly relevant. Objective. To analyze clinical and laboratory characteristics of patients with moderate COVID-19. Materials and methods. This retrospective study included 132 patients with moderate COVID-19 treated in the Republican Immunological Center of the Republic of Dagestan between July and December 2020. The sample included 69 males and 63 females with a mean age of 52.4 ± 5.9 years. Results. The most common clinical manifestations included fever, fatigue, dry cough, and headache. Many participants had increased erythrocyte sedimentation rate (ESR);some patients had leukopenia, lymphopenia, and thrombocytopenia. Biochemical testing demonstrated mild alterations in the levels of C-reactive protein (CRP), ferritin, glucose, activity of liver enzymes (alanine aminotransferase, as-partate aminotransferase), fibrinogen, and D-dimer. These alterations were primarily observed in COVID-19 patients with CT-2 changes in their lung tissue. One-third of participant had lesions in lungs upon discharge. ECG changes (rhythm and conduction abnormalities) were detected in 15.9% of patients with concomitant cardiovascular diseases. Conclusion. COVID-19 patients with persistent clinical, laboratory, or radiological changes upon their discharge from hospital, as well patients with changes on ECG, require careful follow-up to assess their long-term outcomes. © 2021, Dynasty Publishing House.

ABSTRACT
INTRODUCTION: COVID-19 is an ongoing pandemic that has lasted more than a year. Patients with multiple comorbidities such as diabetes, hypertension, and smoking have been shown to be at increased risk of a more severe course and lethal outcome. Since the disease can also lead to a hypercoagulable state, several cases of acute myocardial infarction (AMI) have also been recorded. MATERIAL AND METHODS: We searched PubMed/Medline for case reports of AMI occurring in COVID-19 positive patients using "acute myocardial infarction", "COVID-19", and "SARS-CoV-2" as keywords. RESULTS: Thirty-three articles covering 37 patients were identified, among which 30 (81.1%) were male, and 7 (18.9%) were females. The mean age of these 37 patients was 52.8 ±15.6 years. Most cases were from the United States (17 cases, 45.9%). Several comorbidities such as hypertension (16 cases, 43.2%), diabetes (14 cases, 37.8%), smoking (8 cases, 21.6%), obesity (3 cases, 8.1%), morbid obesity (1 case, 2.7%), and elevated lipid levels (4 cases, 10.8%) were also identified. The most common symptom of AMI was chest tightness (22 cases, 59.5%), while the most common symptoms for COVID-19 were dyspnoea (25 cases, 67.6%) and fever (22 cases, 59.5%). The mortality rate was 35.1%. CONCLUSIONS: Given the high mortality rate, physicians are encouraged to properly check for signs of cardiac dysfunction and possible AMI while treating COVID-19 positive patients with several comorbidities or previous history of AMI.
