Otherwise, from the viewpoint of hypokalemia correction, all the patients with pre-existing hypokalemia (patients 1, 2, 6, 7, 8 and 9) were spared from requiring oral potassium supplements suggesting partial biochemical improvement, though we could not evaluate biochemical success because of decreased pre-operative ARR due to elevated PRA in the unsuppressed PRA group. This evidence concerns the gene S100A6 and Hypokalemia.
