Comparison of effect between intracoronary and intravenous nitrite. A: EDPVR, end-diastolic pressure-volume relationship; B: LVEST, left ventricular electrosystolic time; C: dP/dtmin; D: tau; E: LVEDP, LV end-diastolic pressure; F: LVESP, LV end-systolic pressure; G: LVEDV, LV end-diastolic volume; H: LVESV, time to LV end-systole; I: MAP, mean arterial pressure; J: stroke work; K: dP/dtmax; L: Starling Contractile Index. **P < 0.01, ***P < 0.001 by Student’s t test. n = 36 for LVEST and MAP, n = 40 for all other parameters.
