Moreover, in these patients, cardiac failure,ischemia-induced myocardial damage, and stunned myocardium were reported.6,7 Laboratory results suggested anincreased lymphopenia, thrombocytopenia, lactate dehydrogenase, CRP, D-dimer,fibrinogen, ferritin, and interleukin-6, as well as decreasedantithrombin.8-10 Some hemostatic conditions, including disseminatedintravascular coagulation, have been reported to occur more frequently inCOVID-19-positive patients.10–12 In the current study, postoperative leukocyte, platelet, andCRP tests were routinely monitored. Here, CRP is linked to heart failure.
