Supports modest salt reduction in mild hypertension; extends benefits to albuminuria and arterial stiffness across ethnic groups.
Does modest salt reduction reduce blood pressure, urinary albumin, and pulse wave velocity in white, black, and Asian patients with mild hypertension?
Modest salt reduction significantly lowers blood pressure, reduces urinary albumin, and improves large artery compliance across white, black, and Asian patients with mild hypertension.
