Compromiso cardiovascular en el lupuseritematoso sistémico / Cardiovascular involvement in patient with systemic lupus erythematosus

ABSTRACT

Lupus erythematosus is a multisystemic disease that compromises principally women in fertile age. The principal affected organs are kidney, SNC, bone marrow and serous membranes. Cardiovascular affection includes pericardium, conduction system, myocardium, valves and coronary arteries. The most frequent valve disease is Libman-Sacks endocarditis, although valvulitis or valve dysfunction can exist as well. The mitral valve is the most affected, followed by the aortic valve. The most frequent valve abnormality is slight to moderate aortic insufficiency, while serious insufficiency or valve disruption is very rare. A physical examination has limited efficacy in the diagnosis of valve disease. A high degree of suspicion associated with echocardiography helps to establish the diagnosis. If surgery is not needed, antiplatelet therapy is recommended for asymptomatic patients, and oral anticoagulation treatment is advised for those with valve disease and evidence of thromboembolic phenomena. Recurrence of the disease has been observed in biological grafts, which makes the use of mechanical prostheses advisable when valve replacement indication exists. The following case shows the clinical evolution of a female patient with a rare but very serious lupus erythematosus complication.
