“…To date, the exact pathophysiological mechanism of pericardial involvement is not fully understood. As proposed mechanisms, systemic inflammatory reaction (with cytokine storm), and endothelial damage induced by COVID-19 may lead to pericardial involvement [52] . Furthermore, COVID-19 induced pericarditis might reflect the expression of ACE2 receptors in epicardial adipocites (mediating the cell entry of SARS-CoV-2) [ 17 , [61] , [62] , [63] , [64] , [65] ], and possibly triggering local inflammation [ 63 , [65] , [66] , [67] , [68] , [69] , [70] ].…”
