Myocardial involvement in lupus erythematosis takes the form of an interstitial myocarditis with cellular infiltration and fibrinoid necrosis. The most lesions are perivascular, and involve the arterioles. The myocardial fibres are involved secondarily to the vascular lesions, or by grossly, damaging sclerosis. The clinical features are variable:--no clinical features, but haemodynamic evidence of abnormal ventricular function, and perhaps sudden death;--arrhythmias and disorders of atrio-ventricular conduction;--cardiac failure, which may be due to a genuine cardiomyopathy (a part may be played by hypertension, pulmonary hypertension, renal failure, constrictive pericarditis or haemodynamically major valve disorders);--abnormalities of the coronary trunk in a certain number of cases. If anti-nuclear antibodies are present in a cardiomyopathy, the presence of DLE or of a drug-induced lupus syndrome must be suspected. There remain some awkward cases which defy classification, and which systematic use of echocardiography and pericardial and myocardial biopsy may be able to define more accurately.

Infants born to mothers with disseminated lupus erythematosus occasionally have transient manifestations of the maternal disease. In six infants with congenital heart block born to mothers with systemic lupus erythematosus we postulated a causative relation. In one of the infants a post-mortem study of the conduction system suggested faulty embryonic development of the atrioventricular node with an abnormally thick annulus fibrosus and the effects of early inflammatory changes. Two of the infants had a cardiomyopathy and three, associated congenital heart disease.

Right and left heart pressures, left ventricular volumes, indices of contractility, myocardial wall stiffness, and coronary blood flow were determined in five young women with systemic lupus erythematosus (SLE) during diagnostic right and left heart catheterization. Examinations revealed (1) increases of right and left ventricular enddiastolic pressures; (2) decreases of cardiac output, stroke volume, ejection fraction, contractility indices, diastolic left ventricular volume inflow; (3) decreases of pharmacologically induced coronary vasodilation in SLE. The results demonstrate impaired pump function, reduced contractility, increased myocardial wall stiffness, and decreased coronary vascular reserve in SLE. It is concluded that lupus cardiomyopathy associated with an impairment of left ventricular function may be apparent in young women with SLE who have no clinical signs of cardiac dysfunction.

Haemodynamic functions, myocardial contractility, and coronary blood flow were measured in five young women with systemic lupus erythematosus. There had been no signs of cardiac involvement. Left and right heart catherterisation excluded abnormal pressure gradients and valvar regurgitation. But left ventricular end-diastolic pressures were considerably raised while cardiac output, stroke volume, ejection fraction, and left ventricular compliance were decreased. Isovolumic indices of myocardial contractility were altered, corresponding to a decreased contractile state of the myocardium. Coronary blood flow was moderately increased at rest, but pharmacologically induced coronary vascular reserve was markedly reduced. It is concluded that in young women with this disease there may be, in the absence of clinical signs of cardiac involvement, haemodynamic abnormalities which must be ascribed to the consequences of a lupus cardiomyopathy.

Two patients, both women, one with "lupus-like" disease, age 51 years, the other a 45-year-old with systemic lupus erythematosus (SLE), developed symptoms and echocardiographic signs of hypertrophic cardiomyopathy. One patient had a family history of sudden maternal death. Neither patient had a history of sustained hypertension and there were no significant valvular lesions detectable to account for the septal and ventricular hypertrophy. The association of SLE or any related condition with hypertrophic cardiomyopathy has not been recorded. In one patient the question of a hereditary cardiomyopathy remains a possibility. The diagnosis of the condition was based on clinical and echocardiographic grounds alone. No endomyocardial biopsies were performed.

We compared the clinical and serological characteristics of 15 patients with onset of systemic lupus erythematosus after the age of 50 with those of 232 younger patients. The sex distribution was similar in both groups. All 15 patients were Caucasian. Autoimmune thyroiditis was found in 20% of the elderly patients. Initial manifestations, which presented more frequently in the older group, included thrombocytopenia (P < 0.05), sicca syndrome (P < 0.01) and cardiomyopathy (P < 0.005), whereas butterfly rash (P < 0.05) presented more frequently in the younger group. Analysis of cumulative clinical symptoms showed that butterfly rash (P < 0.05) and livedo reticularis (P < 0.05) were less frequent in the elderly. However, this group presented a significantly increased incidence of sicca syndrome (P < 0.005) and cardiomyopathy (P < 0.005). Antibodies to double-stranded DNA tended to occur less frequently in older patients (P < 0.05).

Pediatric cases of systemic lupus erythematosus with an unfavorable outcome (terminal renal failure requiring chronic hemodialysis, or death) assembled during a retrospective multicenter study of pediatric SLE in the Paris metropolitan area were analyzed. Seven patients (6 girls, 1 boy) were entered into a chronic hemodialysis program. Four had diffuse proliferative glomerulonephritis, the pattern of glomerular disease classically responsible for end-stage renal failure. The other three patients had membranous glomerulonephritis with active segmental lesions, a form of glomerulopathy whose severe prognosis deserves to be emphasized. Nine other patients (8 girls, 1 boy) died. In six patients, death occurred as a result of a flare with malignant hypertension and progressive renal failure (1 case), pancreatitis (1 case), encephalopathy (2 cases) or cardiomyopathy (2 cases). An infectious disease (tuberculosis, mumps) was apparently the cause of the two cases of encephalopathy. One girl died as a result of a hemorrhagic syndrome with a cerebral hematoma. Two other girls died at home. Overall, among 111 children with SLE 14% had an unfavorable outcome. Sex and age at onset seemed to have no bearing on prognosis. Patients with renal involvement were apparently more likely to have an unfavorable outcome. Lastly, although the influence of ethnic origin is unproven, children living in foreign countries of French overseas territories, but treated in France have an increased risk for unfavorable outcomes.

Even in 1990 there are still conflicting views concerning oral contraception (OCs) and risks associated with pregnancy in women with systemic lupus erythematosus. With regard to OCs, all authors agree that estrogen-progestin combinations are harmful, but the best alternative hormonal contraception has yet to be found. Progestin-based micropills seem to be harmless; cyproterone acetate appears to have no side effects and its usefulness in preventing recurrences is being evaluated. With regard to pregnancy, it would be wise not to contemplate having a child until 6 months have passes since onset of remission. Blood pressure, platelet count, and serum creatinine and uric acid levels must be closely monitored. 2 types of antibodies may be present in the mother and may be responsible for fetal complications. These are antibodies to phospholipids (antiprothrombinase, anticardiolipin, antibodies responsible for dissociated treponema serology), which expose patients to spontaneous abortion or intrauterine death, and the antibody to SS-A (or anti-Ro), which exposes patients to fetal cardiomyopathy and congenital atrioventricular block.

Subclinical myocardial involvement frequently occurs in patients with systemic lupus erythematosus (SLE). In this study, left ventricular diastolic function was assessed in 58 patients (54 female and 4 male; mean age 32 +/- 11 years) and in 40 sex-matched and age-matched healthy control subjects (37 female and 3 male; mean age 33 +/- 9 years) by means of pulsed Doppler echocardiography. All subjects had no clinical evidence of overt myocardial disease or abnormal left ventricular systolic function. Compared with the control group, patients with SLE had significantly prolonged isovolumic relaxation time (62 +/- 12 vs 80 +/- 14 msec; p less than 0.01), reduced peak early diastolic flow velocity (peak E) (82 +/- 18 vs 76 +/- 16 cm/sec; p less than 0.05), increased peak late diastolic flow velocity (peak A) (45 +/- 7 vs 53 +/- 8 cm/sec; p less than 0.01), reduced E/A ratio (1.81 +/- 0.32 vs 1.46 +/- 0.29; p less than 0.001), and lower deceleration rate of early diastolic flow velocity (EF slope) (489 +/- 151 vs 361 +/- 185 cm/sec2; p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

In recent years, the cardiovascular manifestations of systemic lupus erythematosus have became more apparent as a consequence of both prolonged survival and improvement in diagnostic modalities. We report the case of a 16-year old woman with systemic lupus erythematosus in whom the presence of cardiomyopathy was characterized by endomyocardial biopsy. This diagnostic technique also showed that the histologic hallmark of lupus myocardiopathy persisted despite corticosteroid and plasmapheresis, suggesting the need of a careful cardiac follow-up in these patients.
