Alternative Approaches to the Assessment of the Systemic Circulation and Left Ventricular Performance: A Proof-of-Concept Study.

ABSTRACT:

Background

The purpose of this article is to examine the systemic circulation and left ventricular (LV) performance by alternative, nonconventional approaches: systemic vascular conductance (G _SV ) and the head-capacity relation (ie, the relation between LV pressure and cardiac output), respectively; in so doing, we aspired to present a novel and improved interpretation of integrated cardiovascular function.

Methods

In 16 open-chest, anaesthetized pigs, we measured LV pressure (P _LV ), central aortic pressure (P _Ao ), and central venous pressure (P _CV ) and aortic flow (Q _Ao ). We calculated heart rate (HR), stroke volume, cardiac index (CI = cardiac o
