Potassium Intake and Risk of Stroke in Women With Hypertension and Nonhypertension in the Women's Health Initiative Clinical Sciences
Conclusions— High potassium intake is associated with a lower risk of all stroke and ischemic stroke, as well as all-cause mortality in older women, particularly those who are not hypertensive.

Dietary Sodium to Potassium Ratio and Risk of Stroke in a Multiethnic Urban Population Clinical Sciences
Conclusions—Na:K intake is an independent predictor of stroke risk. Further studies are required to understand the joint effect of Na and K intake on risk of cardiovascular disease.

Intakes of magnesium, potassium, and calcium and the risk of stroke among men
ConclusionsA diet rich in magnesium, potassium, and calcium may contribute to reduced risk of stroke among men. Because of significant collinearity, the independent contribution of each cation is difficult to define.

Serum Potassium Is Positively Associated With Stroke and Mortality in the Large, Population-Based Malmo Preventive Proȷect Cohort Clinical Sciences
Background and Purpose—Low serum potassium is associated with stroke in populations with cardiovascular disease, hypertension, and diabetes mellitus but has not been studied in a mainly healthy population. We aimed to study the relation between serum potassium and incident stroke and mortality in the Malmö Preventive Project, a large cohort with screening in early mid-life and follow-up>25 years.Methods—Serum potassium measurements and covariates were available in 21 353 individuals (79% men, mean age 44 years). Mean follow-up time was 26.9 years for stroke analyses and 29.3 years for mortality analyses. There were ...

Association of Initial Potassium Levels with the Type of Stroke in the Emergency Department
Early differentiation of hemorrhagic stroke from ischemic stroke in patients with suspected stroke is essential for subsequent management of the patient. While serum potassium level has been suggested as a marker of acute hemorrhagic conditions,1, 2 little is known about whether the initial serum potassium levels differ based on the type of stroke. If serum potassium levels can help differentiate hemorrhagic stroke from ischemic stroke, this information can be applied in deciding subsequent treatment procedures (e.g., catheter intervention, tissue plasminogen activator administration, and antihypertensive therapy) in setti...

Factors Influencing Quality of Life in Stroke Patients: Focus on Eating Habits
This study aimed to identify lifestyle factors about eating habits that may affect the quality of life (QOL) in elderly stroke patients. Methods: Fifty elderly patients with a first-ever stroke were enrolled. QOL was assessed by the Stroke and Aphasia QOL Scale-39-J. Lifestyle factors about eating habits were collected using questionnaires (Questions 1-17) for the intake of salt, calcium, magnesium, potassium, taurine, fiber, and protein, and the frequency of breakfast.

Repurposing the KCa3.1 Blocker Senicapoc for Ischemic Stroke
AbstractSenicapoc, a small molecule inhibitor of the calcium-activated potassium channel KCa3.1, was safe and well-tolerated in clinical trials for sickle cell anemia. We previously reported proof-of-concept data suggesting that both pharmacological inhibition and genetic deletion of KCa3.1 reduces infarction and improves neurologic recovery in rodents by attenuating neuroinflammation. Here we evaluated the potential of repurposing senicapoc for ischemic stroke. In cultured microglia, senicapoc inhibited KCa3.1 currents with an IC50 of 7  nM, reduced Ca2+ signaling induced by the purinergic agonist ATP, suppressed express...

Calcium and potassium channels in experimental subarachnoid hemorrhage and transient global ischemia.
Authors: Kamp MA, Dibué M, Schneider T, Steiger HJ, Hänggi D Abstract Healthy cerebrovascular myocytes express members of several different ion channel families which regulate resting membrane potential, vascular diameter, and vascular tone and are involved in cerebral autoregulation. In animal models, in response to subarachnoid blood, a dynamic transition of ion channel expression and function is initiated, with acute and long-term effects differing from each other. Initial hypoperfusion after exposure of cerebral vessels to oxyhemoglobin correlates with a suppression of voltage-gated potassium channel activity...

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Urinary Sodium and Potassium, and Risk of Ischaemic and Haemorrhagic Stroke (INTERSTROKE): a case-control study.
CONCLUSION: The association of sodium intake and stroke is J-shaped, with high sodium intake a stronger risk factor for intracerebral haemorrhage than ischemic stroke. Our data suggest that moderate sodium intake - rather than low sodium intake - combined with high potassium intake may be associated with the lowest risk of stroke and expected to be a more feasible combined dietary target.

Association between intakes of magnesium, potassium, and calcium and risk of stroke: 2 cohorts of US women and updated meta-analyses.
CONCLUSIONS: A combined mineral diet score was inversely associated with risk of stroke. High intakes of magnesium and potassium but not calcium were also significantly associated with reduced risk of stroke in women. PMID: 25948665 [PubMed - as supplied by publisher]

Lower Serum Potassium Levels at Admission are Associated with the Risk of Recurrent Stroke in Patients with Acute Ischemic Stroke or Transient Ischemic Attack
Conclusions: Lower serum potassium level was independently associated with elevated risk of recurrent stroke in patients with AIS or TIA. The finding suggested that monitoring serum potassium may help physicians to identify patients at high risk of recurrent stroke and to stratify risk for optimal management.Cerebrovasc Dis
