Introduction And Objectives: The cardiac sequelae of SARS-CoV-2 infection are still poorly documented. We conducted a cross-sectional study in healthcare workers to report evidence of pericardial and myocardial involvement after SARS-CoV-2 infection.
Methods: We studied 139 healthcare workers with confirmed past SARS-CoV-2 infection. Participants underwent clinical assessment, electrocardiography, and laboratory tests, including immune cell profiling and cardiac magnetic resonance (CMR). Clinically suspected pericarditis was diagnosed when classic criteria were present and clinically suspected myocarditis was based on the combination of at least 2 CMR criteria.
Results: Median age was 52 (41-57) years, 71.9% were women, and 16.5% were previously hospitalized for COVID-19 pneumonia. On examination (10.4 [9.3-11.0] weeks after infection-like symptoms), participants showed hemodynamic stability. Chest pain, dyspnea or palpitations were present in 41.7% participants, electrocardiographic abnormalities in 49.6%, NT-proBNP elevation in 7.9%, troponin in 0.7%, and CMR abnormalities in 60.4%. A total of 30.9% participants met criteria for either pericarditis and/or myocarditis: isolated pericarditis was diagnosed in 5.8%, myopericarditis in 7.9%, and isolated myocarditis in 17.3%. Most participants (73.2%) showed altered immune cell counts in blood, particularly decreased eosinophil (27.3%; P<.001) and increased cytotoxic T cell numbers (17.3%; P <.001). Clinically suspected pericarditis was associated (P <.005) with particularly elevated cytotoxic T cells and decreased eosinophil counts, while participants diagnosed with clinically suspected myopericarditis or myocarditis had lower (P <.05) neutrophil counts, natural killer-cells, and plasma cells.
Conclusions: Pericardial and myocardial involvement with clinical stability are frequent after SARS-CoV-2 infection and are associated with specific immune cell profiles.

ObjectivePatients who do not wait (DNW) to be seen are a problem for emergency department (ED) care. The aim of this study was to identify the rate and reasons of DNW patients during 1month of the COVID-19 pandemic.MethodsAn observational cohort study of DNW patients presenting to Austin Hospital ED was carried out in August 2021.

Purpose: Few investigational reports have evaluated the status of cardiovascular manifestations of coronavirus disease 2019 (COVID-19) during the Omicron dominance period. In this study, we aimed to investigate the cardiac function parameters and clinical outcomes of patients with COVID-19 before and after the Omicron variant (OV) propagation.
Methods: We retrospectively analyzed the data of 88 adult patients with COVID-19 who underwent clinically indicated standard transthoracic echocardiography (TTE) in intensive care wards.

Molecules were proposed to block the functional cycles of the influenza virus A and SARS-CoV- 2. The blocker molecules efficiently bind inside the M2 and E channels of influenza A and SARS-CoV-2 viruses and block diffusion of H^(+)/K^(+) ions, thus distorting the virus functional cycle. A family of positively charged (+2 e.
