Correlations suggest norepinephrine may mediate dietary sodium effects on LV mass in at-risk normotensives; hypothesis-generating and should not yet change practice.
Do different sodium and potassium intakes alter left ventricular mass and catecholamine levels in normotensive subjects with hypertensive parents?
Dietary sodium intake alters endogenous catecholamine levels, which strongly correlate with rapid changes in left ventricular mass in normotensive individuals predisposed to hypertension.
Trimarco et al. (1985) studied this question.
