The clinico-echocardiographic characteristics of heart involvement in seronegative spondylarthritis (Reiter's disease, Bechterew's disease and psoriatic arthritis)

As many as 136 patients (76 with Bechterew's disease, 40 with Reiter's disease and 20 with psoriatic arthritic) and 35 practically healthy persons were examined by echocardiography combined with electro-, phonocardiographic and by clinical, x-ray and laboratory methods. 62 patients were examined over time (within a period from 1 to 4 years). Echocardiography was used to study in detail the central and intracardiac hemodynamics, the status of the valvular apparatus of the heart and of the aorta. The different clinical characteristics of the disease were established to make a concrete contribution to the development of cardial pathology. The disease duration is the most significant characteristics. A long-term prospective follow-up coupled with echocardiographic examinations made over time enabled one to specify the structure of heart damage in patients suffering from Bechterew's disease, Reiter's disease and psoriatic arthritis depending on the hypothetic nature of the damage.
