To evaluate the impact of dietary sodium and potassium (Na-K) ratio on mortality from total and subtypes of stroke, cardiovascular disease (CVD) and all causes, using 24-year follow-up data of a representative sample of the Japanese population.
Prospective cohort study.
In the 1980 National
OBJECTIVE
High intakes of calcium, potassium, and magnesium have been hypothesized to reduce risks of cardiovascular disease, but only a few prospective studies have examined intakes of these cations in relation to risk of stroke.
METHODS
In 1980, 85 764 women in the Nurses' Health Study cohort,
OBJECTIVE
The association of high sodium intake with risk of stroke has been accepted. But considering the proposed J/U-shaped association between sodium intake and risk of all-cause mortality, the shape of the dose-response relationship has not been determined yet. This study aimed to test the
OBJECTIVE
Potassium intake has been inconsistently associated with risk of stroke. Our aim was to conduct a meta-analysis of prospective studies to assess the relation between potassium intake and stroke risk.
METHODS
Pertinent studies were identified by a search of PubMed from January 1966 through
BACKGROUND
Animal experiments and epidemiological studies have suggested that high potassium intake may reduce the risk of stroke, but the evidence is inconclusive, and the role of other nutrients in potassium-rich foods remains unknown.
RESULTS
We examined the association of potassium and related
Our previous study demonstrated that high potassium (K) diets reduce stroke mortality in stroke-prone spontaneously hypertensive rats (SHRsp) even when the blood pressure is not lowered. On the other hand, macrophage infiltration into the vascular wall is known to play an important role in the
OBJECTIVE
We aimed to investigate the associations of dietary and total potassium, magnesium, and calcium intakes with stroke occurrence.
METHODS
A prospective cohort study was conducted among 36 094 participants aged 21 to 70 years. Dietary intake was assessed with a food frequency
Stroke mortality represents the third leading cause of death worldwide, after coronary artery disease and cancer. High blood pressure is a major risk factor for stroke. A recent study has identified potassium, magnesium, and fiber as significant modulators of stroke risk in men. The protective
BACKGROUND
A high intake of magnesium, calcium, and potassium and a low intake of sodium have been hypothesized to reduce the risk of stroke. However, prospective data relating intake of these minerals to risk of stroke are inconsistent.
METHODS
We examined the relationship of dietary magnesium,
During ischemic stroke, a fatal biochemical cascade that results in neuronal hyperexcitability is initiated when neurons at risk are exposed to excessive excitatory amino acids and pathologically high levels of intracellular calcium (Ca(2+)). Therefore, neuroprotectants including NMDA-antagonists
High potassium (K) diets are known to have a protective effect on the endothelium and the kidney against hypertensive injury independent of blood pressure change. Vasodepressor prostaglandins (PGs) have been shown to be cytoprotective in various tissues. This study investigated the effect of high K
Endothelial dysfunction has been linked to a decrease in nitric oxide (NO) bioavailability and attenuated endothelium-derived hyperpolarizing factor (EDHF)-mediated relaxation. The small (SK(Ca)) and intermediate (IK(Ca)) calcium-activated potassium channels play a key role in endothelium-dependent
Two lines of evidence strongly support the hypothesis that high potassium diets protect arterial endothelial cells from hypertensive damage. Stroke-prone spontaneously hypertensive rats (SHRSP) fed normal (0.75%) K or high (2.1%) K and normotensive Wistar-Kyoto rats (WKY) were examined in an
There is growing evidence that increased dietary sodium (Na) intake increases the risk of vascular diseases, including stroke, at least in part via an increase in blood pressure. Higher dietary potassium (K), seen with increased intake of fruits and vegetables, is associated with lower blood
OBJECTIVE
Various studies suggest that deficiency of magnesium and potassium may be associated with increased risk of ischemic stroke. However, single time-point serum measurements may not be suitable for assessing long-term tissue levels.
METHODS
We investigated Mg and K levels in hair of patients
