Data from ten healthy subjects (left) and from the coronary artery disease population, which is divided into one group of patients with imaging signs of disease (n = 97, right) and one lacking imaging signs of disease (n = 19, middle) in terms of left ventricular wall mass index (LVMI), systolic blood pressure (SBP), diastolic ejection fraction (DSP), wall motion, late gadolinium enhancement and a history of myocardial infarction. BMI body mass index, DBP diastolic blood pressure, LVEDV left ventricle end diastolic volume, LVESV left ventricle end systolic volume, MI myocardial infarction, PCI percutaneous coronary intervention, LGE late gadolinium enhancement, global percentage. Mean with standard deviation
