In order to verify the extent and the frequency of cardiac complications in rheumatoid arthritis (RA), the authors performed mechanophonocardiographic studies and simultaneous mono- and bi-dimensional echocardiography in 28 patients with RA, 2 men and 26 women aged between 38 and 65 (mean = 51) (history of the disease ranging from 1 to 37 years). One case showed an increase in the PEP:LVET ratio on the polycardiogram and 18 cases showed echocardiographic alterations (64.3%), in particular: pericardial effusion in 6 cases (21.

[Biometric evaluation of the use of a battery of tests for studying the rheumatoid factor].

The research has been executed on a sample embracing 253 patients affected with rheumatid arthritis (ARA criteria), 177 patients affected with osteoarthritis and 104 healthy subjects forming the standard sample. On the serum of every subject we have used a series of five different tests in order to find the rheumatoid factor.
