Potassium is the major intracellular electrolyte and the relationship between its intracellular and extracellular levels is the main determinant of the electric potential of the membranes; any significant change in extracellular potassium concentration can therefore have effects not only on metabolic functions, but also in nerve conduction, with muscular repercussions; hypokalemic polymyopathy is a reflection of this.
According to a review of 40 cats diagnosed with the disorder (DJAJADININGRAT-LAANEN et al., 2011), hypertension was observed in 31 of 37 cats submitted to blood pressure assessment; ocular changes, including hyphema, mydriasis, increased tortuosity of the retinal vessels, edema and retinal detachment, were observed in 10 of 19 animals submitted to ophthalmologic evaluation; hypokalemic polymyopathy was observed in 19 of 40 cases; signs of congestive heart failure was present in one cat, and no abnormalities were reported in two patients by the first physical assessment.
If hypokalemic polymyopathy is observed, the levels of creatine kinase (CK) are markedly increased (AHN, 1994).
