Adjustment and Characterization of an Original Model of Chronic Ischemic Heart Failure in Pig

Table 1

Morphometric and functional analysis at basal time and during the follow-up. LVTDD: Left Ventricle TeleDiastolic Dimension. LVTDV: Left Ventricle TeleDiastolic Volume, dIVSW: diastolic InterVentricular Septal Wall, dPLVW: diastolic Posterior Left Ventricle Wall, E/Ea: Peak mitral inflow velocity—E- and Early diastolic—Ea-peak myocardial velocities with Tissue Doppler Imaging, LAV: Left Atrial Volume, WMS ant: Anterior Wall Motion Score, WMS inf: Inferior Wall Motion Score, and WMS Sept: Septal Wall Motion Score. Data are in mean ± SD. *P <.05, **P <.01 compared to basal time.
