  • Values are means (SD). BMI, body mass index; HR, heart rate; LVEDP, left ventricular (LV) end-diastolic pressure; LVEDV, LV end-diastolic volume; LVEF, ejection fraction; LVESV, LV end-systolic volume; LVMI, LV mass index; MAP, mean arterial pressure; SV, stroke volume; τ, time constant of isovolumic relaxation; NS, not significant.

  • * τ was not calculated for one subject in the LVH group due to technical difficulties during data acquisition.
