Abstract

Objective: Silent myocardial involvement is associated with poor prognosis in patients with systemic sclerosis (SSc). Here we aimed to evaluate the subclinical left ventricular (LV) and right ventricular (RV) systolic dysfunction in patients with SSc without any cardiovascular diseases, by using both strain imaging methods, speckle tracking echocardiography (STE) and real-time 3D echocardiography (RT3DE).

 

Methods: A total of 47 patients with SSc and 20 age- and gender-matched healthy controls (HC) were studied. Conventional echocardiography, STE-based strain imaging, and real-time 3D echocardiography (Bothell, WA, USA) were performed to assess the biventricular deformation. Clinical and serological findings were sought.

 

Results: Conventional echocardiographic LV measurements were similar between SSc and HC. Both the LV and RV longitudinal peak systolic strain/strain rates were significantly impaired in SSc, demonstrating subclinical LV and RV systolic dysfunction (p≤0.001). Systolic pulmonary artery pressure (SPAP) was negatively correlated with both the LV and RV longitudinal peak systolic strain/strain rates (LV, r=−0.554 and r=−0.642, respectively, p<0.001; and RV, r=−0.554 and r=−0.642, respectively, p=0.001). There was a trend for decreasing LV strain and increasing LEVSV in a 1-year analysis of patients with SSc.

 

Conclusion: SSc is associated with myocardial systolic dysfunction. A deformation scrutiny conducted by both the STE-based strain imaging and end-systolic LV volume analysis by real-time 3D echocardiography are promising modalities that allow us for non-invasive, comprehensive investigation of subtle deterioration in the biventricular systolic function of patients with SSc.
