pubmed-article:8994433 | pubmed:abstractText | Previous studies with radiotracer methods have indicated increases in cardiac norepinephrine (NE) and renal NE spillover in patients with severe congestive heart failure (CHF). However, data on the regional sympathetic profile in early stages of CHF are limited. In this study, sympathetic function in the heart, kidneys, and skeletal muscle was evaluated in patients with mild-to-moderate CHF and compared with that in patients with severe CHF and healthy subjects. | lld:pubmed |
