Objective The aim of this study was to evaluate the left ventricular (LV) systolic strain by four‐dimensional speckle tracking echocardiography (4D‐STE) in order to provide the early detection of myocardial dysfunction in patients with Sjögren's syndrome (SS). Methods Forty consecutive patients with primary SS diagnosed at the rheumatology outpatient clinic and 35 age‐ and sex‐matched healthy volunteers were included in the study. 4DSTE was performed, and global longitudinal strain (GLS), global circumferential strain (GCS), global radial strain (GRS), and global area strain (GAS) were measured. 4DSTE results were compared with the healthy volunteers. Results No significant differences were observed between the GRS and GCS values of the two groups. A significant difference was observed in the GLS and GAS measurements between the two groups (P = .005 for GLS, P < .001 for GAS). Positive correlation was detected between disease duration and LV‐GLS and LV‐GAS. Conclusion We demonstrated subclinical systolic dysfunction in SS patients by 4DSTE, which is a sensitive marker of ventricular dysfunction. Deterioration of the LV became more evident as duration of the disease increased. Therefore, we believe that a cardiac evaluation will be of benefit to patients with long‐term SS.
