cAMP and cGMP signaling cross-talk: role of phosphodiesterases and implications for cardiac pathophysiology.

abstract：:Controversy exists whether positive end-expiratory pressure (PEEP) ventilation lowers cardiac output by reducing left ventricular preload, or by a combination of mechanisms. Sixteen open-chest dogs were instrumented for measurement of left and right ventricular pressure, aortic flow, and left ventricular dimensions. W...
