Key result
Dietary sodium manipulation altered cardiac angiotensin formation, with a low sodium diet resulting in a more negative aorta-coronary sinus gradient (-9.7 +/- 3.1 pg/mL, P < .01).
Why the study?
Does dietary sodium variation affect the cardiac production of angiotensins in patients with atypical chest pain?
Observational (n=24)
Does dietary sodium variation affect the cardiac production of angiotensins in patients with atypical chest pain?
This study provides in vivo evidence of a functional cardiac renin-angiotensin system in humans that responds to dietary sodium independently of the circulating RAS.
No takes yet. Share an insight, caveat, or question.
Low-sodium intake may modulate cardiac angiotensin handling; extends mRNA evidence for local RAS but leaves clinical relevance open.
Serneri et al. (1996) conducted an observational in Atypical chest pain (n=24). Low or high sodium diet vs. Normal sodium diet was evaluated on Cardiac production rate of angiotensins. Dietary sodium manipulation altered cardiac angiotensin formation, with a low sodium diet resulting in a more negative aorta-coronary sinus gradient (-9.7 +/- 3.1 pg/mL, P < .01).
