Figure 2 Individual and Pooled Group Differences in Changes in Cardiac Function and Remodeling

Forest plot showing individual and pooled changes in left ventricular ejection fraction, end-diastolic volume index, and end-systolic volume index at follow-up comparing late PCI versus best medical therapy only for infarct-related artery occlusion late (>12 h) in the course of acute myocardial infarction. (A) Shows a +4% change in left ventricular ejection fraction favoring PCI. (B and C) Show a significant greater decrease in left ventricular end-diastolic volume index and left ventricular end-systolic volume index in the PCI, showing a more favorable remodeling pattern with PCI. TOSCA-2 = Total Occlusion Study of Canada; other abbreviations as in Figure 1.
