[Echocardiographic analysis of changes in the heart in patients with systemic lupus erythematosus]

Area of Science:

• Cardiology
• Rheumatology
• Medical Imaging

Context:

• Systemic lupus erythematosus (SLE) is a chronic autoimmune disease affecting multiple organ systems.
• Cardiac involvement in SLE can range from pericarditis to valvular disease and myocardial dysfunction.
• Echocardiography is a key non-invasive tool for assessing cardiac structure and function.

Purpose:

• To evaluate the prevalence and spectrum of cardiac abnormalities in patients with systemic lupus erythematosus using echocardiography.
• To identify specific echocardiographic findings associated with SLE, including pericardial disease, valvular lesions, and myocardial function.
• To assess the diagnostic challenges of Libman-Sacks endocarditis in SLE patients.

Summary:

• Echocardiographic examination of 56 SLE patients revealed pericardial effusion in 27% and thickening in 37.5%.
• Libman-Sacks endocarditis was suspected in 7.5% of patients. Left ventricular hypertrophy was observed in 37.5%, and myocardial hypocontractility was infrequent.
• Pulmonary hypertension was detected in 3.6% of cases. Pericardial involvement is frequent, while diffuse myocardial disease is uncommon in SLE.

Impact:

• Highlights the high frequency of pericardial involvement in SLE, emphasizing the need for routine echocardiographic screening.
• Underscores the diagnostic difficulties associated with Libman-Sacks endocarditis, suggesting further research for improved detection.
• Provides insights into the pattern of cardiac manifestations in SLE, differentiating between pericardial and myocardial involvement.
