Key result
Continuous intravenous adenosine increased pulmonary capillary wedge pressure by 19% (+2.6 mm Hg, P<0.001) due to changes in vascular loading rather than direct effects on cardiac function.
Why the study?
What is the mechanism of adenosine-induced elevation of pulmonary capillary wedge pressure in patients with normal rest left ventricular function?
What is the mechanism of adenosine-induced elevation of pulmonary capillary wedge pressure in patients with normal rest left ventricular function?
Effect estimate: 19% increase
p-value: p=<.001
Adenosine-induced elevation of pulmonary capillary wedge pressure is primarily caused by a redistribution of blood volume toward the central thorax rather than direct myocardial effects.
No takes yet. Share an insight, caveat, or question.
Adenosine PCWP rise reflects thoracic volume redistribution; challenges direct myocardial assumptions and leaves open relevance in LV dysfunction.
Nussbacher et al. (1995) studied Normal rest left ventricular function (n=15). Adenosine was evaluated on Pulmonary capillary wedge pressure (PCWP) (19% increase, p=<.001). Continuous intravenous adenosine increased pulmonary capillary wedge pressure by 19% (+2.6 mm Hg, P<0.001) due to changes in vascular loading rather than direct effects on cardiac function.
