Why the study?
Does handgrip exercise augment muscle sympathetic nerve activity in patients with heart failure compared to normal subjects?
Does handgrip exercise augment muscle sympathetic nerve activity in patients with heart failure compared to normal subjects?
Heart failure patients, particularly those with reduced exercise capacity, exhibit an augmented sympathetic reflex response to exercise driven by the muscle metaboreflex.
No takes yet. Share an insight, caveat, or question.
Suggests caution during isometric exercise in low-capacity HF; leaves open whether metaboreflex modulation improves outcomes.
Notarius et al. (2001) studied this question.
