CRT in Patients with Heart Failure: Time Course of Perfusion and Wall Motion Changes

Table 3

Correlation matrix between percent of variation of the analysed variables. T0: time 0, T1: first step of followup, T2: second step of followup. EDVi: end diastolic volume index, ESVi: end systolic volume index, SMS: summed motion score, STS: summed thickening score, SRS: summed rest score, and EF: ejection fraction.

(a) Percent of variable variations at T1.
