Meta-analysis of potassium intake and the risk of stroke

Journal of the American Heart Association, 11/04/2016 Vinceti M, et al.

For this study, researchers played out a systematic review and meta–analysis of existing studies and evaluated the dose–response connection between potassium consumption and stroke risk. Overall, this dose–response meta–analysis affirms the inverse relationship between potassium consumption and stroke risk, with potassium consumption of 90 mmol (≈3500 mg)/day connected with the lowest risk of stroke. Methods and Results

• In this study researchers looked into the observational cohort studies tending to the connection between potassium consumption, and incidence or mortality of total stroke or stroke subtypes published through August 6, 2016.
• They carried out a meta–analysis of 16 cohort concentrates on in view of the relative risk (RR) of stroke comparing the highest versus lowest consumption categories.
• They additionally plotted a pooled dose–response curve of RR of stroke according to potassium consumption.
• Investigations were performed with and without adjustment for blood pressure.
• Relative to the lowest category of potassium consumption, the highest category of potassium consumption was connected with a 13% diminished risk of stroke (RR=0.87, 95% CI 0.80–0.94) in the blood pressure–adjusted examination.
• Summary RRs tended to diminishing when original estimates were unadjusted for blood pressure.
• Examination for stroke subtypes yielded comparable results.
• In the spline examination, the pooled RR was lowest at 90 mmol of potassium daily consumption (RRs=0.78, 95% CI 0.70–0.86) in blood pressure–adjusted investigation, and 0.67 (95% CI 0.57–0.78) in unadjusted examination.
