TI  - Potential candidates for cardiac resynchronization therapy in Japanese patients 
      with idiopathic dilated cardiomyopathy--a Niigata multicenter study of DCM--.
PG  - 1104-9
AB  - BACKGROUND: The purpose of this study was to assess the candidates suitable for 
      cardiac resynchronization therapy (CRT) and to examine the significance of the 
      QRS duration in Japanese patients with idiopathic dilated cardiomyopathy (DCM). 
      METHODS AND RESULTS: The study population consisted of 357 patients. The 
      selection criteria for candidates suitable for CRT were QRS duration =130 ms, 
      left ventricular ejection fraction (LVEF) =35% and New York Heart Association 
      (NYHA) functional class III or IV by ACC/AHA/NASPE 2002 guidelines. We divided 
      the study population into 2 groups: group A with a QRS duration <130 ms, and 
      group B with a QRS duration =130 ms. In 25 of the 375 patients (7.0%), all the 
      criteria were fulfilled. Group B had a significantly larger left ventricular 
      diameter end-diastole and end-systole than group A (P<0.0001). Group B had a 
      lower LVEF (P<0.0001). There was a fair inverse correlation (r=-0.58, P<0.0001) 
      between the length of the QRS duration and LVEF. CONCLUSION: Approximately 7% of 
      the Japanese patients with DCM are CRT candidates. In the present study, we found 
      that prolonged QRS duration was associated with poor systolic function.
