Pericardial involvement in asymptomatic patients undergoing long-term hemodialysis: an echocardiographic study.

Abstract

M-mode echocardiography was performed in 20 asymptomatic patients undergoing chronic hemodialysis, in order to assess pericardial involvement. Six of the patients had small to moderate amounts of pericardial effusion. One of these patients and 5 others showed an echocardiographic pattern of pericardial thickening. No correlation was found between pericardial involvement and age, sex, secondary hyperthyroidism, serum levels of urea, creatinine or uric acid. The traditional diagnostic techniques commonly used for the detection of pericardial disease such as physical examination, chest X-ray and electrocardiography were not helpful in our patients. Our study demonstrates the high incidence of pericardial involvement in asymptomatic chronically dialyzed patients. Periodic echocardiographic evaluation is recommended for assessment of the presence and significance of these findings.
