Patient selection
A total of 96 consecutive patients (28 women and 68 men; mean age, 56 ± 8 years) with LV systolic dysfunction and diffuse asynergy as a result of either ischemic or nonischemic dilated cardiomyopathy, or specific heart muscle disease, were enrolled. All patients underwent Doppler echocardiography, and 45 underwent cardiac catheterization (initial examination) as clinically indicated. All patients had been clinically stable for at least 4 weeks on oral therapy. Inclusion criteria were in sinus
Baseline characteristics
Baseline clinical, M-mode, 2D, color flow Doppler, pulsed, and Doppler tissue echocardiographic data (96 patients) and hemodynamic characteristics (45 patients) in the 3 groups are presented in Table 1. Heart rate and systolic blood pressure were significantly increased and lower, respectively, in group 3 than in group 1. The percentage of patients in NYHA functional class III or IV was greater in groups 2 and 3 than in group 1. LV EF was lower in groups 2 and 3 than in group 1, although the LV
Discussion
This is the first report to demonstrate that the atrial systolic mitral annular motion velocity obtained by pulsed DTI is a better predictor for prognosis or severity of pulmonary congestion compared with E-DT, E/A of transmitral flow velocity, or E of transmitral flow velocity/Ew of mitral annulus in patients with LV systolic dysfunction.
Recently, it has been reported that the transmitral flow velocity is useful index for evaluating LV diastolic function, and that it predicts outcome in
