[Echocardiographic functional analysis of patients with rheumatoid arthritis and collagen diseases].

Cardiac manifestations were observed in patients with rheumatoid arthritis and other collagenoses. Echocardiography is a method of choice to detect pathologies in morphology and function of the heart. Pathophysiologically inflammatory alterations of the endo- as well as perimyocardium can be explained in these patients. In addition, in patients with collagenoses, the coagulation system is activated and the reactivity of the endothelium is reduced. Thus, thrombus formation at the heart valves with consecutive stenosis and/or regurgitations as well as ischemia-induced regional wall motion defects due to reduced vasodilator response of the coronary arteries can be expected. In the literature in patients with rheumatoid arthritis and other collagenoses, pericardial effusion and pulmonary hypertension are most frequently described. The echocardiographic analysis, however, is more complex due to the variability of the patient cohort. Quantification of valve defects and the analysis of wall motion and perfusion at rest and during stress is necessary to detect early changes of the diseases. The prerequisites for successful diagnostic echocardiography in these patients are the knowledge of modern echocardiographic techniques like tissue Doppler and contrast echocardiography and clinical experience with patients with rheumatoid arthritis and other collagenoses. The standardization of the echocardiographic diagnostic procedure becomes more and more important for reproducibility and comparability of the results.
