Background and Objectives: It has been suggested that the indices based on tissue doppler and color M-mode echocardiography reflect the left ventricular end-diastolic pressure. These include the early diastolic transmitral velocity (E) to early myocardial velocity ratio measured by tissue doppler (E') and the E to the wave propagation velocity (Vp) ratio measured from color M-mode images. However, these indices have not been well validated in congestive heart failure patients.
Subjects and Methods: Thirty one congestive heart failure patients who underwent simultaneous cardiac catheterization and echocardiography, and had normal sinus rhythm were enrolled in this study. The left ventricular end-diastolic pressure obtained from the left heart catheterization was compared with the diastolic indices using pulsed doppler, tissue doppler and color M-mode echocardiography.
Results: The left ventricular end-diastolic pressure (LVEDP) ranged from 3.3 to 23 mmHg. Some parameters showed a significant correlation with the LVEDP. The propagation velocity showed a significant correlation with the LVEDP(r＝0.382, p＝0.034), and the E to propagation velocity ratio (E/Vp) showed a good correlation with the LVEDP(r＝0.408, p＝0.023). In addition, the E to early diastolic velocity of the mitral annulus (E') ratio had an insignificant correlation with the
LVEDP(r＝0.322, p＝0.078). Among the patients with ischemic congestive heart failure, the E to the propagation velocity ratio (E/Vp) showed a marginal correlation with the LVEDP (r＝0.461, p＝0.047).
Conclusion: In patients with congestive heart failure, the Vp and E/Vp showed a good correlation with the LVEDP. In the subgroup of patients with ischemic congestive heart failure, only the E/Vp showed a significant correlation with the LVEDP.
