Valvular heart disease associated with systemic lupus erythematosus - the Tygerberg Hospital experience
Insights
Systemic lupus erythematosus (SLE) frequently causes valvular heart disease, with thickening being most common. However, significant valvular dysfunction is rare in SLE patients.
Area of Science:
- Cardiology
- Rheumatology
- Internal Medicine
Background:
- Valvular heart disease is a significant cardiac complication of systemic lupus erythematosus (SLE).
- Understanding the prevalence of cardiac involvement in SLE is crucial for patient management.
Purpose of the Study:
- To investigate the presence and characteristics of valvular heart disease in patients with SLE.
- To compare echocardiographic findings in SLE patients with a healthy control group.
Main Methods:
- Clinical assessment, electrocardiography, transthoracic echocardiography, and laboratory tests were conducted on 24 SLE patients.
- Echocardiographic results were compared to those of 10 age- and sex-matched healthy volunteers.
Main Results:
- No SLE patients reported cardiac symptoms.
- Valvular abnormalities were common in SLE patients, with valvular thickening (over 50%) being the most prevalent finding.
- Mitral regurgitation and pericardial effusions were observed in 12.5% of SLE patients, while uncommon in controls.
Conclusions:
- Valvular heart disease is a frequent finding in patients with SLE.
- Despite common abnormalities, hemodynamically significant valvular dysfunction is rare in this population.
Abstract:
BACKGROUND: Valvular heart disease is the most important cardiac manifestation of systemic lupus erythematosus (SLE). We performed a study to determine the presence of valvular heart disease in our patients with SLE. METHODS: We performed clinical, electrocardiographic, transthoracic echocardiographic and laboratory evaluations in 24 patients with SLE. The echocardiographic findings were compared with those of 10 age- and sex-matched volunteers. RESULTS: None of the 24 patients had obvious symptoms of cardiac origin. Valvular abnormalities were common. Valvular thickening was the most predominant finding (more than 50%), followed by mitral valvular regurgitation (12.5%) and pericardial effusions (12.5%). Valvular abnormalities were uncommon in the control group. CONCLUSION: Valvular heart disease is common in our patient population with SLE, although haemodynamically significant valvular dysfunction is rare.
