Indices of left ventricular function. Data obtained at baseline, after ischemia/reperfusion (IR) protocol, initial AVP infusions (AVP-initial), mean pressure of 90 mmHg (AVP-90 mmHg) and after drug withdrawal (Withdrawal) (n = 9). dP/dt max and min (mmHg/sec), maximal acceleration and declaration of pressure in the cardiac cycle; PRSWi (mmHg), slope of preload recruitable stroke work index; Tau (ms), time constant of isovolumetric ventricular relaxation; SW (ml/mmHg), stroke work; EDP (mmHg), end diastolic pressure; Ees (mmHg/ml), end systolic elastance; EDPVR (mmHg/ml), end diastolic pressure volume relationship. All values are obtained by left ventricle pressure-volume catheter at steady state or vena cava occlusions (PRSWi, Ees and EDPVR). *Significant difference from (IR); †significant difference between (AVP-90 mmHg) and (Withdrawal).
