  1. Values are mean ± SD or n (%); p-values are given for the comparison of primary versus secondary prevention. BP blood pressure; LVEDV left ventricular end–diastolic volume; LVESV left ventricular end–systolic volume; LVEF left ventricular ejection fraction; LGE late gadolinium enhancement; RV right ventricle; LV LGE pattern was categorized according to reference [11]
