      capacity of patients with heart failure].

AB  - OBJECTIVES: We investigated correlations between the New York Heart Association 
      (NYHA) functional classification system, which is commonly used to assess 
      functional capacity, and conventional echocardiographic and tissue Doppler 
      echocardiographic (TDE) parameters in patients with heart failure (HF). STUDY 
      DESIGN: The study included 122 patients (31 females, 91 males; mean age 59+/-11 
      years) with HF, whose left ventricular (LV) ejection fraction (EF) was less than 
      50%. The patients were evaluated in two groups based on the NYHA class I-II 
      (n=79; mean age 58 years) and class III-IV (n=43; mean age 61 years). 
      Correlations were sought between the functional status and standard 
      two-dimensional echocardiographic and TDE parameters. RESULTS: The NYHA class 
      showed significant inverse correlations with LV EF, LV stroke volume, mitral 
      deceleration time of early filling, and flow propagation velocity (Vp), and 
      significant positive correlations with end-systolic and end-diastolic diameters 
      and volumes, pulmonary artery pressure (PAP), and the E/Vp ratio. Mitral early 
      (E) and late (A) diastolic peak velocities and the E/A ratio were not correlated. 
      Concerning TDE parameters, the NYHA class was in significant inverse correlation 
      with systolic (Sm), early (Em) and late (Am) diastolic myocardial velocities, and 
      in positive correlation with the E/Em ratio, whereas no correlation was found 
      with the Em/Am ratio. Linear regression analysis showed that Sm, EF, and PAP were 
      independent variables of functional capacity (beta =-0.33, p<0.005; beta =-0.26, 
      p<0.05; beta =0.23, p<0.05, respectively). CONCLUSION: There is significant 
      relationship between myocardial velocities and functional capacity, and Sm, in 
      particular, has the strongest association compared to conventional 
      echocardiographic and other TDE parameters.
