Values are n (%), mean (SD), or median (interquartile range). CMR = cardiovascular magnetic resonance; EDVI = end-diastolic volume index; EF = ejection fraction; ESVI = end-systolic volume index; IQR = interquartile range; LGE = late gadolinium enhancement; LV = left ventricle; RV = right ventricle; SD = standard deviation
