Table 2.
Baseline (2–4 week) and final (6 month) CMR imaging characteristics. All morphologic parameters are indexed to body surface area, calculated at the time of CMR. The “Δ” (change) indices are calculated as final (6-month) value minus baseline (4-week) value divided by initial value. Late gadolinium enhancement was measured by the full-width half-maximum technique.
