Sodium ions, calcium ions, blood pressure regulation, and hypertension: a reassessment and a hypothesis

Blaustein, M. P.·1977·American Journal of Physiology-Cell Physiology

Abstract

An attempt is made to elucidate the cellular mechanisms which may account for the well-documented correlation between sodium metabolism and peripheral vascular resistance. As a starting point, the evidence that the Na electrochemical gradient across the vascular smooth muscle cell plasma membrane (sarcolemma) plays an important role in cell calcium regulation is reviewed. Because there is significant resting tension (“tone”) in most resistance vessels, the ionized Ca2+ level ([Ca2+]1) in the smooth muscle fibers in these vessels must be maintained above the contraction threshold. Consequently, the Ca transport system in the sarcolemma, presumably an Na-Ca exchange mechanism, must be set so as to hold [Ca2+]1 at this suprathreshold level. Any change in the Na gradient will then be reflected as a change in [Ca2+]1 and, therefore, in steady vessel wall tension and peripheral resistance. The correlation between Na metabolism and hypertension could then be accounted for if a circulating agent, perhaps the “natriuretic hormone,” affects the Na gradient (across the sarcolemma) and, therefore, [Ca2+]1 and tension.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
