AB  - This study was designed to clarify the validity of Doppler indices for assessment 
      of the severity of congestive heart failure in patients with dilated 
      cardiomyopathy. Left ventricular (LV) and right ventricular (RV) Doppler indices, 
      defined as the sum of isovolumic contraction time and relaxation time divided by 
      the ejection time, were obtained in 30 normal subjects and 35 patients with 
      ischemic or idiopathic dilated cardiomyopathy. We analyzed the correlation 
      between New York Heart Association (NYHA) functional class, right-sided cardiac 
      pressure, and the Doppler indices. Patients with dilated cardiomyopathy revealed 
      significantly higher LV and RV Doppler indices than normal subjects; however, the 
      LV Doppler index did not correlate significantly with NYHA functional class or 
      right-sided cardiac pressure. On the other hand, the RV Doppler index correlated 
      significantly with NYHA functional class (rs = 0.83, P < 0.001), pulmonary 
      capillary wedge pressure (r = 0.80, P < 0.001), pulmonary artery systolic 
      pressure (r = 0.81, P < 0.001) and pulmonary artery diastolic pressure (r = 0.77, 
      P < 0.001). Both RV isovolumic contraction and relaxation time also correlated 
      significantly with right-sided cardiac pressure. In 12 patients who improved from 
      NYHA III-IV to I-II after treatment, the RV Doppler index decreased from 0.84 +/- 
      0.25 to 0.33 +/- 0.10 (P < 0.001), while the LV Doppler index did not change 
      significantly (0.72 +/- 0.27 to 0.68 +/- 0.23, P = 0.53). These results suggest 
      that the RV Doppler index is useful for assessment of the severity of congestive 
      heart failure in patients with dilated cardiomyopathy.
