Evaluation of the Frequency of Hypokalemia in Patients on Diuretic Therapy for Heart Failure

The study demonstrated that hypokalemia was common among HF patients receiving diuretic therapy, particularly loop diuretics in high doses. Although loop diuretic use and higher doses were significant independent predictors, the efficacy of interventions like dose adjustment or potassium-sparing drugs needs to be further validated in future randomized controlled trials.
