title: Detection of preclinical impairment of myocardial function in rheumatoid arthritis patients with short disease duration by speckle tracking echocardiography.
abstract: BACKGROUND
  Subclinical cardiac involvement diagnosis is important for long term management of rheumatoid arthritis (RA) patients. Recently, 2D speckle tracking echocardiography (STE) allows non invasive and angle-independent measurement of left ventricular (LV) dimensions and regional myocardial strain (ε). The aim of this study was to assess whether STE can be useful to detect subclinical cardiac involvement in RA patients.
  
  
  METHODS
  We studied 22 RA patients (10 M, 12 F, aged 46 ± 12 years) without clinical evidence of coronary artery disease (CAD) and 20 healthy controls matched for age and sex by STE. LV end-systolic longitudinal and radial ε from apical 4-chamber view were analyzed using available software (QLAB 6.0).
  
  
  RESULTS
  Standard echo and Doppler parameters did not differ between the 2 groups. Tissue Doppler Imaging (TDI) showed a significant reduction of S', E' and E'/A' ratio from the basal septum and lateral mitral annulus in RA patients. LV end-systolic radial and longitudinal ε of basal-lateral, basal- and mid-septal, mid-lateral and apical segments were significantly reduced compared to controls.
  
  
  CONCLUSIONS
  Our data indicate that LV end-systolic radial and longitudinal ε are reduced in RA patients without CAD despite normal standard echo. Non invasive evaluation of LV function by STE appears to be useful to detect subclinical cardiac involvement in comparison to conventional 2D echoDoppler, representing a promising new modality to follow-up RA patients for cardiac involvement.
