Insights
Systemic lupus erythematosus (SLE) patients often have silent heart issues. Myocardial perfusion scintigraphy can detect these subclinical heart problems, identifying SLE patients at risk for future cardiovascular events.
Area of Science:
- Cardiology
- Rheumatology
- Nuclear Medicine
Background:
- Cardiovascular disease (CVD) is a leading cause of death in Systemic Lupus Erythematosus (SLE) patients.
- Autopsy studies reveal high rates of myocardial and coronary injury in SLE, often without clinical symptoms.
- Clinical manifestations of CVD in SLE occur in less than 10% of cases.
Purpose of the Study:
- To evaluate myocardial perfusion in patients diagnosed with Systemic Lupus Erythematosus (SLE).
- To identify subclinical myocardial involvement in SLE patients using noninvasive imaging.
Main Methods:
- 153 patients with Systemic Lupus Erythematosus (SLE) were included.
- 94 patients underwent 99mTc-tétrofosmin SPECT imaging at rest and during stress.
- Analysis correlated perfusion abnormalities with clinical events and risk factors.
Main Results:
- The average disease duration was 11 years, with a mean age of 37 years.
- Abnormal myocardial perfusion was detected in 22.3% of SLE patients.
- Perfusion abnormalities significantly correlated with a history of stroke (p<0.01) and coronary events (p<0.02).
Conclusions:
- Myocardial perfusion scintigraphy is a valuable noninvasive tool for detecting subclinical cardiac involvement in SLE.
- This imaging technique can help identify SLE patients at increased risk for future cardiovascular events.
- Early identification of myocardial involvement may allow for timely intervention in SLE patients.
Introduction:
Cardiovascular disease is a major cause of morbidity and mortality in patients with systemic lupus erythematosus (SLE). Necropsy studies found a high incidence of myocardial and coronary injuries while clinical manifestations were observed in less than 10%. The purpose of this study was to evaluate myocardial perfusion in SLE patients.
Patients And Methods:
The study was carried out in 153 patients with a definite diagnosis of SLE according to the revised criteria of the American College of Rheumatology. Ninety-four (61.4%) underwent 99mTc-tétrofosmine SPECT analysis at rest and after stress.
Results:
The average disease duration was 11 years. Ninety-four patients (93 women and one man) with a mean age 37 years were assessed. Twelve had a past history of vascular event: six stroke, four angina pectoris and two myocardial infarctions. Cardiovascular risk factor included: high blood pressure (35.2%), dyslipidemia (62.3%), moderate hyperhomocysteinemia (55%), BMI greater than 25 (40%).The cumulative prednisone dose per patient was 45.5g. Myocardial perfusion stress scanning showed abnormal perfusion in 21 patients (22.3%). Among these, eight underwent coronary angiography which was normal in seven cases. One patient had a right coronary stenosis. Perfusion abnormalities were correlated with stroke (p<0.01) and coronary events (p<0.02).
Conclusion:
Myocardial perfusion scintigraphy can be a useful noninvasive method to identify subclinical myocardial involvement in systemic lupus erythematosus and patients at risk of later events.
