Cardiovascular manifestations develop in the majority of SLE patients at some time during the course of their illness, the most common being acute fibrinous pericarditis and pericardial effusion. Echocardiography has demonstrated an increased incidence of pericardial effusion, even in those who have minimal symptoms. Chronic adhesive pericarditis, pericardial tamponade, and constrictive pericarditis occur rarely. While myocarditis is commonly noted at autopsy, it is often silent clinically. Diagnosis during life can be confirmed only by endomyocardial biopsy. Electrocardiographic changes are often nonspecific. Endocarditis with superimposed nonbacterial verrucous vegetations (Libman-Sacks) is noted in more than 40% of hearts at autopsy, but is rarely diagnosed during life. Valve dysfunctions, such as aortic stenosis, aortic insufficiency, mitral stenosis, and mitral insufficiency, occasionally manifest during life and rarely may necessitate surgery. Atrial and ventricular arrhythmias, first degree AV block, and acquired CHB occur in association with pericarditis, myocarditis, vasculitis, and myocardial fibrosis, respectively. CCHB developing in newborns of mothers with SLE, particularly those who have an antibody to soluble tissue ribonuclear protein RO(SS-A), is increasingly being appreciated by both pediatric cardiologists and rheumatologists. Recently, severe coronary atherosclerosis resulting in angina pectoris and/or myocardial infarction in young adults has been noted, particularly in those who had developed risk factors such as hypertension and hyperlipidemia while receiving prolonged corticosteroid therapy. Rarely, coronary arteritis may produce similar symptoms. Congestive heart failure of either single or multiple etiologies carries an ominous prognosis. It remains a cause of high morbidity and mortality unless recognized early and treated properly. Extracardiac vascular manifestations of SLE include telangiectasia, vasculitis, livedo reticularis, Raynaud's phenomena, and thrombophlebitis, all of which may occur either alone or in different combinations. Evidence is now slowly accumulating that substantiates that immune complex deposition, complement activation and subsequent inflammatory reaction is responsible for the majority of the cardiovascular manifestations of SLE, for example, pericarditis, myocarditis, endocarditis, coronary arteritis, coronary atherosclerosis, and systemic and pulmonary vasculitis.(ABSTRACT TRUNCATED AT 400 WORDS)

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.
