BACKGROUND: Systemic lupus erythematosus (SLE) is a chronic multisystem autoimmune disease of undetermined etiology. Cardiac involvement is common in SLE and constitutes one of the main causes of mortality. More recently, new ultrasound imaging techniques, such as transthoracic ultrasound (TTE) with strain evaluation, have appeared and seem promising for the detection of cardiac involvement. The objective of our work was to study the frequency and characteristics of ultrasound abnormalities found in lupus patients and to study the benefit of ultrasound with global longitudinal strain (GLS) for early management.
METHODS: It was an observational study of patients followed for SLE at the internal medicine and cardiology department of the HMPIT for 6 months (May-November 2023). The definition of cardiac involvement was by ultrasound. All patients benefited from TTE coupled with 2D-strain. We divided the workforce into two groups: the first group (patients with heart disease) and the second group (patients without heart disease).
RESULTS: In a series of 40 lupus patients including 33 women and seven men, cardiac manifestations were reported in 60% of patients. In the first group, 29% had palpitations, 25% had chest pain, 67% had dyspnea, 37% had pericarditis, 8% had pulmonary arterial hypertension (PAH) and 12% had myocarditis. The comparative study showed that patients in the first group presented significantly more frequently with dyspnea (p = 0.02), chest pain (p = 0.03) and serositis (p = 0.01) compared to those in the second group. The mean left ventricular ejection fraction (LVEF) did not show a significant difference between the two groups. On the other hand, the average Global Longitudinal Strain (GLS) was significantly altered in the first group (p = 0.01). Furthermore, the frequency of pathological GLS was significantly higher in patients with lupus heart disease (p < 0.01).
CONCLUSION: Cardiac involvement during SLE is a frequent and most often asymptomatic complication. A systematic search for this impairment using a high-performance echocardiography examination, namely the 2D GLS, is essential for early treatment.
