|• cardiac function (aortic FV-systolic; mitral FV-diastolic);
• myocardial perfusion (coronary FV-coronary flow reserve);
• pressure-overload by stenosis (left & right carotid FVs and stenotic jet FV at aortic arch);
• arterial stiffness (aortic arch & abdominal FVs to determine pulse wave velocity); and
• peripheral perfusion (renal, carotid, iliac, femoral, saphenous vein FVs).
