N: expresses the number of patients with a transmurality index > 75% in the acute CMR. Δ: expresses the change of the variables from the acute to the chronic CMR.
Data expressed as mean and standard deviation.1Data expressed as mean (percentages).
Min: minutes. WMSI: Wall motion score index. Num: number. EDV: end-diastolic volume. ESV: end-systolic volume. EF: ejection fraction.
