Cardiac involvement in systemic lupus erythematosus.

Area of Science:

• Cardiology
• Rheumatology
• Internal Medicine

Background:

• Pericarditis is the most frequent cardiac abnormality in patients with systemic lupus erythematosus (SLE).
• Historically, cardiac manifestations in SLE were severe and life-threatening, often discovered post-mortem.
• Contemporary understanding reveals that cardiac involvement in SLE is frequently mild and asymptomatic, detectable through noninvasive methods.

Purpose of the Study:

• To highlight the prevalence and nature of cardiac abnormalities in SLE.
• To emphasize the diagnostic utility of echocardiography in SLE patients.
• To discuss the mechanisms and management of cardiovascular complications in SLE.

Main Methods:

• Review of clinical observations and diagnostic techniques for cardiac manifestations in SLE.
• Focus on the role of echocardiography in identifying pericarditis, valvular lesions, and myocardial dysfunction.
• Analysis of causes for vascular occlusion, including premature atherosclerosis and antiphospholipid antibodies in SLE.

Main Results:

• Echocardiography demonstrates high sensitivity and specificity for detecting cardiac abnormalities in SLE, including mild pericarditis.
• Vascular complications, such as coronary artery disease (CAD), are common in SLE patients, primarily driven by premature atherosclerosis.
• Cardiac manifestations in SLE are now often mild and asymptomatic, contrasting with historical severe presentations.

Conclusions:

• Periodic echocardiography is recommended for SLE patients to monitor for cardiac abnormalities.
• Managing traditional and SLE-specific risk factors is crucial to prevent atherosclerotic plaque development and CAD.
• Early detection and management of cardiac involvement are essential for improving outcomes in SLE patients.
