  1. Values are expressed as means ± SD. *P < .05 and **P < .01 vs corresponding value at baseline.
  2. ✝P < .05 and ✝✝P < .01 vs corresponding value in Non-inducible. HR, heart rate; E/A, ratio of early to late transmitral inflow velocity; DcT, deceleration time of early transmitral inflow velocity; ET, ejection time; ICT, isovolumic contraction time
