Abstract

The regulation of blood pressure (BP) is subject to the influence of various exogenous factors, such as a nutritional origin. It is now well established that excess sodium has a deleterious hypertensive effect. On the other hand, the beneficial impact of dietary potassium remains relatively under-reported, despite the fact that this cation has been shown to have a significant antihypertensive effect and to help reduce the risk of major cardiovascular (CV) events. This article provides an up-to-date summary of the scientific data on the effects of dietary potassium on BP and CV morbidity and mortality, detailing the underlying pathophysiological mechanisms and suggesting dietary strategies for optimising potassium intake.

La régulation de la pression artérielle (PA) est soumise à l’influence de divers facteurs exogènes, notamment d’ordre nutritionnel. Il est aujourd’hui bien établi que l’excès sodique exerce un effet hypertensif délétère. En revanche, l’impact bénéfique du potassium alimentaire reste relativement méconnu, bien qu’il soit démontré que ce cation exerce une action antihypertensive significative et contribue à la réduction du risque d’événements cardiovasculaires (CV) majeurs. Cet article propose une synthèse actualisée des données scientifiques relatives aux effets du potassium nutritionnel sur la PA et la morbimortalité CV, en détaillant les mécanismes physiopathologiques sous-jacents et en suggérant des stratégies diététiques visant à optimiser l’apport potassique.
