Abstract

1. Increased sodium intake causes decreased formation of angiotensin (Ang) II and increased AngII causes increased Na+ retention. 2. Increased sodium intake and increased AngII causes cardiac hypertrophy, but decreased sodium intake regresses cardiac hypertrophy despite high AngII levels. Likewise, decreased Na+ and blockers of the renin-angiotensin system (RAS) in neonatal rats have similar effects on subsequent blood pressure development. 3. Cardiac hypertrophy due to renal hypertension does not regress when the RAS is blocked and rats are on a high salt intake. Likewise, sodium restriction alone does not cause regression; combination of reduced NaCl intake and RAS blockade is required. 4...
