Key result
Muscle sympathetic nerve activity was significantly inversely correlated with radial artery compliance in patients with congestive heart failure (r = 0.62, P < 0.01).
Why the study?
Does sympathetic tone modulate radial artery compliance in humans, including those with congestive heart failure?
Population
17 patients with congestive heart failure and other subjects undergoing physiological testing

May indicate sympathetic restraint on radial compliance in HF; leaves open causal role and therapeutic implications.
Does sympathetic tone modulate radial artery compliance in humans, including those with congestive heart failure?
Effect estimate: r = 0.62 (inverse correlation)
p-value: p=<.01
Sympathetic tone exerts a pronounced tonic restraint on radial artery compliance, which is inversely correlated with muscle sympathetic nerve activity in patients with congestive heart failure.
Grassı et al. (1995) conducted a review in Congestive heart failure (n=17). Sympathetic activation was evaluated on Radial artery compliance (r = 0.62 (inverse correlation), p=<.01). Muscle sympathetic nerve activity was significantly inversely correlated with radial artery compliance in patients with congestive heart failure (r = 0.62, P < 0.01).
