Abstract:
Objective To analyse the relationship between the left ventricular longitudinal systolic velocities quantified by DTI and the cardiopulmonary performance in patients with dilated cardiomyopathy(DCM). Methods Maximal oxygen consumption(VO2max) and systolic velocities were assessed in 68 patients with DCM during their regular follow-up. Peak velocities during isovolumic contraction (is) and ejection (ez) were assessed at the site of anal, at the middle of the wall, and at the middle site between the two sites of interventricular septum (S), lateral wall (L) of LV in apical 4 chambers view. Results Peak velocities during IVC and ejection in group of patients(32cases) with VO2max
