Values are presented as median (interquartile range) or n (%).
aLow D-dimer group was defined as D-dimer ≤0.5 μg/mL and high D-dimer group as D-dimer >0.5 μg/mL.
CMR = cardiac magnetic resonance; LV = left ventricle; AAR = area at risk; MSI = myocardial salvage index; MVO = microvascular obstruction; LVEDV = left ventricular end diastolic volume; LVESV = left ventricular end systolic volume; LVEF = left ventricular ejection fraction.
