  1. Values are presented as means (SD). BSA indicates body surface area; E/A: early to late diastolic mitral inflow velocity ratio; E/e’: early diastolic mitral inflow to annular velocity ratio; LA: left atrium; LVEDV: left ventricular end-diastolic volume; LVM: left ventricular mass; MBF: myocardial blood flow
  2. †Myocardial blood flow analysis performed after excluding those with infarct (T2D n = 5, controls n = 0), regional ischemia (T2D n = 17, controls n = 1), or did not undergo adenosine stress due to technical/clinical reasons (T2D n = 25)
