Table 3 Mean (± SD) and p values for the significant univariate correlates of the two-group comparisons between patients with and those without 6-month increases in LV end-diastolic volume (EDV, left panel) or in ejection fraction (EF, right panel)

From: Cardiac remodeling following reperfused acute myocardial infarction is linked to the concomitant evolution of vascular function as assessed by cardiovascular magnetic resonance
