Suggests sympathetic role in canine hypertension models; leaves open human translation and therapeutic targeting.
Does continuous electrical stimulation of the left stellate ganglion induce sustained arterial hypertension in conscious dogs?
Mean Difference: 25
Continuous stimulation of the stellate ganglion in conscious dogs leads to sustained rises in both blood pressure and peripheral resistance, apparently mediated by increased sympathetic nervous system activity.
Liard et al. (1975) studied hypertension (n=6). Electrical stimulation of the left stellate ganglion vs. Baseline (control values) was evaluated on Systemic blood pressure (MD 25 mm Hg). Continuous electrical stimulation of the left stellate ganglion in conscious dogs led to sustained increases in blood pressure by an average of 25 mm Hg and peripheral resistance by 35±4%.
