  1. MSIMI: mental stress-induced myocardial ischaemia; TPD: total perfusion deficit; EDV: end-diastolic volume; ESV: end-systolic volume; LVEF: left ventricular ejection fraction; SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate; RPP: rate–pressure product. P values < 0.05 are shown in bold
