Key result
Massive sympathetic activation significantly diminished left ventricular function compared with control (P<0.01), an effect prevented by catecholamine antagonists.
Why the study?
Are catecholamines and hypertension-induced myocardial energy demands responsible for depressed left ventricular function following massive sympathetic nervous system activation in rabbits?
Are catecholamines and hypertension-induced myocardial energy demands responsible for depressed left ventricular function following massive sympathetic nervous system activation in rabbits?
p-value: p=<0.01
Toxic concentrations of catecholamines and increased myocardial energy demand from hypertension are key contributors to left ventricular dysfunction following massive sympathetic activation.

May implicate catecholamines in post-SNS LV dysfunction; leaves open clinical relevance pending in vivo validation.
Pilati et al. (1992) studied Left ventricular dysfunction. Massive sympathetic nervous system activation (intracisternal veratrine) vs. Intravenous veratrine (control) was evaluated on Left ventricular function (p=<0.01). Massive sympathetic activation significantly diminished left ventricular function compared with control (P<0.01), an effect prevented by catecholamine antagonists.
