Abstract: The livers of 30 autopsies of cor pulmonale were observed morphorlogically.Hepatic congestion,fatty degeneration,atrophy of hepatic cells,detachment of hepatic plate and the focal necrosis of hepatic cells were the main features among the findings.An acute necrosis of the lobular central hepatic cells resulting from hypoxia appeared in four patients with serious hypoxemia lasting a week.The mechanism of this hepatic cell necrosis was discussed.The author conclude that the patient with cor pulmonale may suffer from cirrhosis,if the heart function is insufficient for a long time.This kind of cirrhosis has the following three characteristics:1.With a long history of heart failure,usually more than 10 years.2.Cirrhosis could follow cot pulmonale,but much less often than other kind of heart diseases. 3.And it is characterized by abnormal lobulation.

Key words: cor pulmonale, coagulation necrosis, abnormal lubolation
