摘要
OBJECTIVE: The aim of the study was to investigate the clinical value of the peak strain dispersion (PSD) in evaluating left ventricular (LV) systolic synchrony in patients with systemic lupus erythematosus (SLE). PATIENTS AND METHODS: 58 SLE patients without cardiovascular diseases and 60 healthy subjects were enrolled in the study. Both groups were examined by transthoracic two-dimensional echocardiography. Traditional parameters were measured by conventional echocardiography. Two-dimensional speckle tracking imaging (2D-STI) was used to analyze the PSD and LV global longitudinal strain (LVGLS). Related ultrasound and blood test results were analyzed and compared. RESULTS: The PSD was significantly higher in SLE patients than in controls (p<0.05). The LVGLS was significantly lower in SLE patients than in controls (p<0.05). The PSD was negatively correlated with the LVGLS. CONCLUSIONS: LV systolic synchrony is impaired in patients with SLE disease. The PSD can be used as a new reliable index to evaluate LV systolic synchrony.
