ABSTRACT
STUDY OBJECTIVE:
To compare parameters of diastolic function as assessed by radionuclide ventriculography (RNVG) and Doppler echocardiography (ECHO) in the patients with chronic heart failure and reduced ejection fraction (HF REF). PATIENTS ANDMETHODS:
RNVG and ECHO were performed on the same day in 40 patients with systolic chronic HF, NYHA II and III, with LV EF < 50 % and sinus rhythm, followed at tertiary HF clinic. Diastolic function was assessed by RNVG using parameters PFR (peak filling rate [% SV/sec]), TFR - time to peak filling rate (ms), and by ECHO using pulse Doppler parameters the peak Doppler velocities of early (E) and late diastolic flow (A), the E/A ratio, the calculated mean of the early (E´) diastolic velocity of septal and lateral mitral annulus measured by tissue Doppler imaging, and the E/E´ ratio.RESULTS:
The mean PFR was 421.7 (median 371.0) % SV/sec and TPF was 198.7 ms (median 169.5), the mean E/A ratio was 1.21 (median 0.85) and the E/E´ ratio was 9.0 (median 8.40). TPF correlated significantly (inverse correlation) with the E/A ratio (r = -0.34, p = 0.030), and not significantly with E´ (r = -0.27, p = 0.082), the PFR/age ratio correlated with the E/E´ ratio (r = -0.31, p = 0.05).CONCLUSION:
Significant correlations of parame-ters of diastolic function as assessed by radionuclide and Doppler studies were identified in the HF REF patients.
