[8] The well-known effect of sodium on blood pressure can be explained by comparing blood to a solution with its salinity changed by ingested salt.
Reduced salt intake also results in a small but statistically significant reduction in blood pressure. [19] [26] Left ventricular hypertrophy (cardiac enlargement): "Evidence suggests that high salt intake causes left ventricular hypertrophy. This is a strong risk factor for cardiovascular disease, independently of blood pressure effects."

[5] [6] Treatment is based on the underlying cause. [4]
