Table 3. Left Ventricular Myocardial Blood Flow and Oxygenation

Hct = hematocrit; VO^2LV= left ventricular oxygen consumption; C = normothermia; H = hypothermia; DO^2LV= left ventricular oxygen delivery; ER^LV= left ventricular extraction ratio; F^GCV= great coronary vein flow/kg; LVSWI = left ventricular stroke work index; RVSWI = right ventricular stroke work index; L^art- L^GCV= left ventricular arterial-venous lactate difference; LV = left ventricular; S^GCVO²= great coronary vein oxygen saturation; P^GCVO²= great coronary vein partial pressure of oxygen; RPP = rate-pressure product; CPP = coronary perfusion pressure. Significance of differences between groups indicated by *P < 0.05 and †P < 0.01. Significance of differences within groups, after correction for multiple comparisons, is indicated by letter symbols where capital letters represent P < 0.05 and lower-case P < 0.01 as follows: A, a for stage 1 vs . 2; B, b for stage 2 vs . 3, 2 vs . 4 and 2 vs . 5; C, c for stage 3 vs . 4 and 3 vs . 5; and D, d for stage 4 vs . 5.
