Fig. 1. Systolic and diastolic left ventricular pressure (LVP) during higher (H) and lower (L) anesthetic exposure at time t = 15 min (left ) and at 120 min of reperfusion (right ). ISC: no anesthetic exposure; H1-15: 0.4 mm (approximately 2.8 vol% at 37°C) for 15 min; H2-5: 0.4 mm (2.8 vol%) for 2 × 5 min with 5-min washout interspersed; L2-5: 0.2 mm (1.4 vol%) for 2 × 5 min with 5-min washout interspersed. Data are expressed as mean ± SD; n = 8/group. P < 0.05 for * ISC versus  H1-15, H2-5, or L2-5; † H1-15 versus  H2-5 or L2-5; ‡ H2-5 versus  L2-5.
