[Polychlorinated biphenyls in human subepicardial fat].

A considerable relation between myocardial fatty infiltration (lipomatosis) and ischemic lesion of myocardium was proved by authors else where. This time, polychlorinated biphenyls (PCB) wee studied in subepicardial fat as well as in subcutaneous fat in thorax and abdomen of deceased person after sudden and violent death. For the time being, most published results concerned the abdominal subcutaneous fat. All the published results showed high concentrations of PCB were proved in subcutaneous fat tissue from thorax and abdominal area and specially in subepicardial fat. Topical relation of PCB deposits and heart muscle was direct in all analyzed case because of fatty infiltration of myocardium. Obviously, a direct toxic effect of PCB on myocardium can take place in stress lypolysis e.g. associated with heart infarct (in some animals hydropericardium and impairment of parenchymatous organs were observed) and prognosis of patients with ischemic lesion can get worser.
