title: Heart disease in systemic lupus erythematosus: diagnosis and management.
abstract: Most patients suffering from systemic lupus erythematosus develop secondary heart disease at some time during the course of the primary illness. The most common forms of this type of heart disease are acute fibrinous pericarditis and hypertension. By means of echocardiography, an increased incidence of pericardial effusion has been demonstrated. Although commonly noted at autopsy, myocarditis is often clinically silent. However, endomyocardial biopsy may confirm its presence during life. Libman-Sacks endocarditis, although encountered in 40 to 50% of hearts at autopsy, is rarely diagnosed during life. When significant valve dysfunction such as aortic insufficiency or mitral regurgitation develops during the course of systemic lupus erythematosus, then Libman-Sacks endocarditis should be strongly suspected. Cardiac arrhythmias, first degree AV block, and acquired complete heart block may develop either de novo or in association with lupus pericarditis, myocarditis, vasculitis, etc. Complete congenital heart block has been reported in newborns of mothers with systemic lupus erythematosus, particularly those who have an antibody to a soluble tissue ribonucleoprotein antigen called RO(SS-A). Coronary arteritis and premature coronary atherosclerosis manifesting in either angina pectoris or myocardial infarction in young adults, particularly women suffering from systemic lupus erythematosus, have received attention recently. The development of hypertension and hyperlipidemia while such patients are receiving prolonged corticosteroid therapy has been incriminated as the significant risk factor in premature coronary atherosclerosis. Longstanding hypertension and congestive heart failure have unfavorable prognoses. This report is based on a cumulative review of 50 patients with acute and chronic systemic lupus erythematosus seen at our institution and in private practice during the last 10 years.
