Potassium Intake and Stroke Mortality Risks
Seth A, Mossavar-Rahmani Y, Kamensky V, et al. Potassium intake and risk of stroke in women with hypertension and nonhypertension in the Women’s Health Initiative. Stroke. 2014;45(10):2874-2880.
This study examined dietary potassium effects on different stroke subtypes over 11 years in 90,137 postmenopausal women aged 50 to 79 years who had no stroke history at enrollment. Mean dietary potassium intake was 2,611 mg per day. The highest quartile of potassium intake was associated with lower incidence of ischemic and hemorrhagic stroke and total mortality. Comparing highest to lowest quartile of potassium intake with multivariate analyses yielded a hazard ratio of 0.90 (95% confidence interval [CI], 0.85-0.95) for all-cause mortality, 0.88 (95% CI, 0.79-0.98) for all stroke, and 0.84 (95% CI, 0.74-0.96) for ischemic stroke.
