Hemodynamic parameters and indices of systolic and diastolic function derived from left ventricle pressure-volume relationship in one-year old pentobarbital anesthetized WAR and Wistar control rats.

*PHR: heart rate, MAP: mean arterial pressure, LVSP: left ventricular systolic pressure, ESV: end-systolic volume, EDP: end-diastolic pressure, EDV: end-diastolic volume, CO: cardiac output, TPR: total peripheral resistance, EF: ejection fraction, dP/dt_max maximal slopes of the systolic pressure increment (+dP/dt_max) and diastolic pressure decrement (-dP/dt_max), ESPVR and EDPVR: slope of end-systolic and end-diastolic pressure-volume relationships, τ: relaxation time constant, PRSW: preload recruitable stroke work.Values are mean ± SEM.Hemodynamic parameters and indices of systolic and diastolic function derived from left ventricle pressure-volume relationship in one-year old pentobarbital anesthetized WAR and Wistar control rats.
