How does serum potassium affect stroke risk and outcome?

Serum potassium is positively associated with stroke and mortality in the large, population-based malmö preventive project cohort. Johnson LS, Mattsson N, Sajadieh A, Wollmer P, Söderholm M Stroke 2017; 48:2973-2978.   Abstract 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… Read More How does serum potassium affect stroke risk and outcome?

Does warfarin cause worse intracranial bleeding than other anticoagulants?

Outcome of intracerebral hemorrhage associated with different oral anticoagulants Wilson D, Seiffge DJ, Traenka C, et al; and the CROMIS-2 collaborators. Neurology 2017; 88:1693-1700.
