Demonstrates organ-specific sympathetic activation in experimental HF; hypothesis-generating for human translation and targeted therapies.
Does chronic heart failure cause regional heterogeneity in sympathetic neural activation of peripheral tissues in a rat model?
Chronic heart failure evokes a central nervous system-mediated increase in basal sympathetic tone that exhibits regional heterogeneity both between and within organs.
Patel et al. (2000) studied this question.
