The purpose of this study was to evaluate the spectrum of morphologic and functional cardiac involvement in a selected population of patients with systemic lupus erythematosus (SLE) by means of echocardiography. Thirteen patients (2 male and 11 female) affected by SLE, mean age 41.9 years (range, 21-64), underwent M-Mode, two-dimensional and Doppler echocardiography. Eleven patients had renal disease and 3 of them were undergoing dialysis. One patient had findings of active disease. Six patients had systemic hypertension. None had a history suggestive of rheumatic fever or infective endocarditis. At echocardiographic study nine patients demonstrated findings of valvular involvement. These alterations were defined, according to the echocardiographic features, in two types: vegetation (verrucous Libman-Sacks endocarditis) and thickening. Vegetations were present in 6 patients, involving the mitral valve in all six and the aortic valve in three. The mitral valve vegetations were more frequent on the subannular portion of the posterior leaflet. Seven patients had valvular thickening: involvement of both mitral and aortic valve was present in five, and isolated mitral or aortic valve lesions in the remaining two patients. Combined valvular vegetation and thickening were observed in 4 patients. Eight patients had mild valvular dysfunction on Doppler examination: five isolated mitral regurgitation, two combined mitral and aortic regurgitation and one combined mitral stenosis and regurgitation. In agreement with previous reports, our study shows that valvular involvement in SLE is relatively frequent. Echocardiography can identify additional patterns of valvular lesions different from the known "verrucous Libman-Sacks endocarditis". The degree of valvular dysfunction is not important.

In order to assess the prevalence of cardiac involvement in the primary antiphospholipid syndrome (PAS), a syndrome which associates thromboembolism, recurrent abortion, the presence of antiphospholipid antibodies and thrombocytopenia, transthoracic (TTE) and trans-esophageal echocardiography (TEE) was performed in 15 patients, 10 women and 5 men with a mean age of 38.8 +/- 11 years, with the PAS but without systemic lupus erythematosus. The presentation of the PAS was a thrombotic event (6 arterial and 7 venous) in 13 cases, and recurrent abortion in 3 cases. Twelve patients had high anticardiolipin antibody levels (> or = 15 U GPL) and 12 had a raised anti-prothrombinase antibody title. Valvular heart disease was detected in 9 patients (60%) as a valve thickening (> or = 5 mm for the mitral and > or = 3 mm for the aortic valve) or nodule. Mitral regurgitation was observed in 4 cases both on TTE and TEE and was mild in 3 cases and severe in 1 case. Aortic regurgitation was diagnosed in 6 patients, in 3 cases by TTE and in 6 cases by TEE. It was mild in 5 cases and moderate in the other cases. Pericardial effusion was observed in 3 patients (20%), alone in 1 case and associated with valvular disease in the other two cases. No abnormality of left ventricular systolic or diastolic function could be demonstrated. In conclusion, cardiac involvement seems to be common in the PAS, and TEE is a sensitive and accurate method for describing the valvular, especially aortic valve, abnormalities.

A 33-year-old female patient, with a 4-year history of hypertension plus a 3-year history of systemic lupus erythematosus, who had been taking high dosages of corticosteroids, has shown repetitive respiratory infections and congestive heart failure for the past 8 months. Angiocardiography confirmed the diagnosis of aortic insufficiency with aneurysmatic dilation of Valsalva's posterior sinus, ascending aorta of normal diameter and normal coronary arteries. Aortic dissection causing aortic insufficiency due to collapse of aortic leaflets was spotted during the surgery and was corrected by a bovine pericardial tube and suspension of aortic valve. The postoperative (PO) period was complicated by left-sided seizures followed by left hemiparesis and respiratory infection. She was discharged on the 25th PO day with mild left hemiparesis and in functional class I (NYHA), using medicines. We emphasize the need to consider the diagnosis of aortic dissection in patients with systemic lupus erythematosus and aortic insufficiency, specially in those who have a history of systemic arterial hypertension and long-term corticosteroid therapy.

Anticardiolipin antibodies (acLa) are associated with a thrombotic tendency (often involving cerebral ischemic events), are frequently present with systemic lupus erythematosus and have been found together with cardiac valve abnormalities. Previous studies evaluated patients characterized by the presence of acLa or lupus, precluding assessment of the frequency of acLa in those with valvular disease. This study aims to establish the prevalence of acLa in patients with valve disease in the absence of lupus and, furthermore, to determine the influence of acLa on the risk of cerebral events in valve disease. Eighty-seven consecutive patients with mitral or aortic regurgitation, or both, prospectively underwent enzyme-linked immunosorbent assay testing for immunoglobulin G (IgG) and M acLa, as did 24 normal subjects. AcLa values greater than or equal to 3 SD above the normal mean were considered "positive." Prior cerebral events were defined retrospectively. Of 87 patients with valvular disease, 26 had positive IgG acLa levels compared with 0 of 24 normal subjects (p less than 0.01). AcLa values did not vary with valve disease etiology. Focal cerebral events had occurred in 8 patients and were embolic or probably embolic in 7, including 7 of 26 IgG acLa-positive and 1 of 60 IgG acLa-negative patients (p less than 0.001). In the absence of lupus, IgG acLa is highly prevalent among patients with aortic or mitral regurgitation, or both; this association may indicate a relatively high risk for cerebral emboli.

To evaluate cardiac involvement in primary antiphospholipid syndrome, two-dimensional and Doppler echocardiographic studies were performed in 34 consecutive patients with this syndrome. All patients had an increased level of serum anticardiolipin antibodies with no evidence of malignancy or systemic lupus erythematosus. The clinical manifestations of primary antiphospholipid syndrome were arterial thrombosis in 14 patients, venous thrombosis in 6 and recurrent fetal loss in 14. Valvular lesions were observed on two-dimensional echocardiography in 11 patients (32%) (9 women and 2 men), aged 24 to 57 years (mean +/- 1 SD 36 +/- 10). Abnormal echocardiographic findings were observed in 9 (64%) of 14 patients with arterial thrombosis versus 1 (17%) of 6 patients with venous thrombosis and 1 (7%) of 14 patients with recurrent fetal loss. The most common echocardiographic abnormality was mitral leaflet thickening, found in five patients; this was associated with mitral regurgitation in three and with combined mild mitral stenosis and regurgitation in one patient. Localized subvalvular mitral thickening was observed in one patient and calcification of the anulus in another. Aortic valve thickening was observed in two patients, one of whom also had a moderate degree of aortic regurgitation. Vegetation-like lesions on the mitral or aortic valve were found in two patients. It is concluded that valvular lesions are commonly found in primary antiphospholipid syndrome, particularly when the syndrome is manifested by peripheral arterial thrombosis. The location and appearance of valvular lesions in this syndrome are heterogeneous. Most patients have no clinically significant valvular disease. Two-dimensional and Doppler echocardiographic studies are often informative in these patients.

Cardiac involvement in patients with systemic lupus erythematosus (SLE) was assessed by full echocardiography and continuous wave Doppler in 50 consecutive patients and 50 age- and sex-matched control subjects in a prospective, blinded study. The left ventricular ejection fraction was decreased in patients compared to control subjects (61 +/- 9 vs 68 +/- 7%, p less than 0.001), whereas interventricular septum (12 +/- 3 vs 9 +/- 1 mm, p less than 0.001), and posterior wall dimension (9 +/- 2 vs 8 +/- 1 mm, p less than 0.001), left ventricular mass (186 +/- 54 vs 130 +/- 32 g, p less than 0.001) and mitral valve Doppler A:E ratio (0.8 +/- 0.2 vs 0.7 +/- 0.1, p less than 0.01) were increased. Pericardial effusion was detected in 27 patients and 5 control subjects, and valvular regurgitation was more frequent in the patients (aortic 2 vs 0; mitral 23 vs 5, p less than 0.001; tricuspid 34 vs 22, p less than 0.01 and pulmonary 28 vs 17, p less than 0.05). Mitral or aortic regurgitation was more common in patients with active SLE (60 vs 40%, difference not significant) but was not related to the duration of SLE (r = 0.02), duration of prednisone therapy (r = -0.13) or current dosage of prednisone (r = 0.01). This study demonstrates that pericardial effusion, valvular regurgitation and myocardial abnormalities are frequently present in patients with SLE.

A prospective M-mode, cross-sectional and Doppler echocardiographic study was performed on 75 patients with systemic lupus erythematosus and 60 sex- and age-matched control subjects. Compared with the control group, patients with lupus had an increased prevalence of echocardiographic abnormalities. These included pericardial effusion and/or thickening (37%), left ventricular hypertrophy (12%), global left ventricular hypokinesis (5%), segmental abnormalities of left ventricular wall motion (4%), right ventricular enlargement (4%), focal verrucous valvar thickening (12%), gross valvar thickening and dysfunction (8%), mitral regurgitation (25%) and aortic regurgitation (8%). Two patients with gross mitral valvar thickening and dysfunction subsequently underwent valvar replacement. Correlation between echocardiographic abnormalities and clinical parameters showed that pericardial effusion was significantly associated with pericardial pain (P less than 0.05) and active disease (P less than 0.001), and left ventricular hypertrophy with systemic hypertension (P less than 0.05). Thus, there was a high prevalence of cardiac abnormalities, especially pericardial and valvar lesions, in patients with systemic lupus erythematosus. Echocardiography is invaluable in identifying these abnormalities and should be used routinely for cardiac evaluation of these patients.

Two patients with positive antiphospholipid antibody and early multi-infarction dementia as a presenting feature of their illness are reported. One was included in the so called primary antiphospholipid antibody syndrome, while the second one met the criteria for systemic lupus erythematosus. We point out to the presence of aortic regurgitation in one of the patients and its possible relation with these antibodies. Although the precise mechanism of thrombosis is incompletely known, the recognition of this type of dementia is of paramount importance as it is a potentially treatable condition.

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)
