摘要：Methods, systems and devices described herein can be used for automaticallyadjusting one or more cardiac resynchronization therapy (CRT) pacing parameters (andmore generally stimulation parameters), to achieve a long term reduction in leftventricular (LV) diastolic pressure (and more generally, preload) of a heart failure (HF)patient. A reduction in LV diastolic pressure is indicative of a reduction in preload (theforce of blood the fills the left ventricle), which is typically indicative of an improvement ina patient's HF condition. In accordance with certain embodiments, when a set ofstimulation parameters is tested, the set is tested for a period that is sufficiently longenough to allow the patient's compensatory mechanisms to react to the set ofstimulation parameters and achieve a substantially steady-state LV diastolic pressurecorresponding to the using the set of stimulation parameters. Such techniques arebelieved to provide better results than achieved using acute hemodynamic optimizationtechniques.
