Differential Associations for Salivary Sodium, Potassium, Calcium, and Phosphate Levels with Carotid Intima Media Thickness, Heart Rate, and Arterial Stiffness.

In age-adjusted analyses, salivary potassium was significantly associated with carotid artery intima media thickness (cIMT) and carotid-femoral pulse wave velocity, and these associations were at the limit of significance in multivariate analyses including prevalent cardiovascular disease and risk factors.

Salivary Electrolytes Are Increased with Age Potassium exhibited a strong and positive association with age ( Figure 2(a) ), whereas the correlation between sodium and age was weaker and did not reach statistical significance ( Figure 2(b) ).
