RESUMO

This study evaluates the frequency and localization of cardiovascular manifestations em SLE through echocardiographic study with Doppler, as well as the associated frequency of anticardiolipin antibodies, chronic use of corticosteroids, activity and duration of the evolution of illness. A prospective study conducted between April , 2000 and December, 2001, included 72 patients of both sexes, with SLE, (45 with active SLE and 27 with inactive SLE) which were compared with a control group of 45 subjects without SLE. Pericardial abnormalities were found only in 35 patients with active SLE, and 28.9% presented pericarditis without effusion; 8.9% with pericardial thickening and 22.2% presenting pericarditis with effusion. Endocardial ? valvular involvement was revealed in 22.2% of the patients with active SLE most of them presenting mitral insufficiency while 37.7% had mitral thickening. In patients with inactive SLE, 14.9% presented mitral thickening. Regarding the involvement of the myocardial, left ventricle hypertrophy was encountered in 20% of the patients with active SLE and in 14.9% of the patients with inactive SLE. Diastolic disfunction of the left ventricle occurred in 17.7% of the patients with active SLE. Elevated pulmonary arterial pressure was found in only 2 (4.4%) patients with active SLE. Systemic arterial hypertension, associated with the myocardial alterations were present in 12.5%, especially in those with left ventricle hypertrophy. Regarding the frequency of anticardiolipin antibodies, no association with involvement of the pericardium was observed; involvement of the myocardia associated with active SLE was found in 7 (15.5%) and in 2 (7.4%) with the inactive illness; association with endocardial ? valvular involvement was found in 3 (6.7%) patients with active SLE and in 1 (3.7%) with inactive SLE. The dimensions of the aortic root, left atrium, left ventricle during diastole, systolic volume, and thickness of the interventricular septum and posterior wall, fractional shortening, right ventricle and parietal thicknesses were evaluated in the two groups of patients with SLE, and, when compared, presented no significant statistical differences. The echocardiography with Doppler can be utilized routinely in cardiovascular investigations of SLE patients and in the ensuing following, as it becomes even more important during the active phase of the illne
