Heart structure and function in patients with generalized autoimmune diseases: echocardiography with tissue Doppler study

Abstract

Echocardiography with TDE reveals characteristic pathology in different forms of generalized autoimmune diseases reflecting their different pathogenetic mechanisms. Overproduction of collagen in SSc results in diastolic left ventricular dysfunction, while generalized inflammation in SLE and DPM leads mainly to pathologic changes on valvular leaflets and/or pericardium. Interestingly, right ventricular dysfunction is common in all diseases analyzed, regardless of the presence of pulmonary hypertension. Echocardiography, preferably with TDE, could add valuable information about usually asymptomatic heart pathology in an individual patient with generalized autoimmune disease.
