A clinicopathological study on pericardial heart disease in the aged

A total of 87 cases of pericardial heart disease (73 of pericarditis and 14 of hemopericardium) among 870 consecutive autopsies of aged patients was studied. Fibrinofibrouspericarditis was found in 80.8% of pericarditis, neoplastic in 13.7% and purulent in 5.5%. Representative cases of each type of pericarditis were illustrated. Among fibrinofibrous pericarditis, idiopathic was the most common and the other causes included irradiation, myocardial infarction, renal failure, rheumatoid arthritis and hypothyroidism. Frequent association of congestive heart failure or anasarca with mild to moderate fibrinofibrous pericarditis was noted. Clinical and morphologic evidences of pulmonary tuberculosis were present in nearly one third of cases with fibrinofibrious pericarditis, but actual incidence of tuberculous pericarditis could not be determined. Incidence of clinical signs and symptoms of acute pericarditis was evaluated with the stress on the relatively high incidence of supraventricular tachyarrhythmias, especially in cases with histological evidence of sinus node involvement in aged cases.
