Myocardial perfusion abnormalities in asymptomatic patients with systemic lupus erythematosus
Insights
Systemic lupus erythematosus (SLE) patients frequently show myocardial perfusion abnormalities, indicating potential heart issues. A history of pericarditis was linked to these findings in a study of SLE patients.
Area of Science:
- Cardiology
- Rheumatology
- Nuclear Medicine
Background:
- Accelerated coronary artery disease and myocardial infarction are known risks in young patients with systemic lupus erythematosus (SLE).
- The prevalence of coronary involvement in SLE patients remains largely undetermined.
Purpose of the Study:
- To investigate the prevalence and characteristics of coronary involvement in patients with SLE.
- To assess myocardial perfusion using exercise thallium-201 cardiac scintigraphy in SLE patients without prior cardiac history.
Main Methods:
- Exercise thallium-201 cardiac scintigraphy was performed on 26 SLE patients.
- Patients were selected irrespective of their previous cardiac history.
Main Results:
- Segmental myocardial perfusion abnormalities were detected in 38.5% (10 of 26) of SLE patients.
- Abnormalities included reversible defects (ischemia) in 5 patients and persistent defects (scar) in 4 patients.
- No correlation was found between positive thallium results and disease duration, corticosteroid use, organ involvement, or age; however, a history of pericarditis was associated with positive results (p < 0.05).
Conclusions:
- Segmental myocardial perfusion abnormalities are common in patients with systemic lupus erythematosus.
- The underlying cause of these abnormalities (large-vessel coronary disease vs. small-vessel disease) requires further investigation.
Abstract:
Accelerated coronary artery disease and myocardial infarction in young patients with systemic lupus erythematosus is well documented; however, the prevalence of coronary involvement is unknown. Accordingly, 26 patients with systemic lupus were selected irrespective of previous cardiac history to undergo exercise thallium-201 cardiac scintigraphy. Segmental perfusion abnormalities were present in 10 of the 26 studies (38.5 percent). Five patients had reversible defects suggesting ischemia, four patients had persistent defects consistent with scar, and one patient had both reversible and persistent defects in two areas. There was no correlation between positive thallium results and duration of disease, amount of corticosteroid treatment, major organ system involvement or age. Only a history of pericarditis appeared to be associated with positive thallium-201 results (p less than 0.05). It is concluded that segmental myocardial perfusion abnormalities are common in patients with systemic lupus erythematosus. Whether this reflects large-vessel coronary disease or small-vessel abnormalities remains to be determined.
