Figure 3 Improvement in Segmental Function After Revascularization Related to Radial Systolic Strain and Hyperenhancement

Relation between peak systolic radial strain and likelihood of increased contractility after revascularization (left), and relation between transmural extent of hyperenhancement and likelihood of increased contractility after revascularization (right). Data are shown for all 463 dysfunctional segments before revascularization. The categories of hyperenhancement are given in the text. The categories of peak systolic radial strain were as follows: 1: >22.9%; 2: 22.9% to 17.2%; 3: 17.1% to 11.4%; 4: 11.3% to 5.6%; 5: <5.5% peak systolic radial strain.
