Hyperkalemia in Heart Failure.
Disorders of potassium homeostasis can potentiate the already elevated risk of arrhythmia in heart failure. Heart failure patients have a high prevalence of chronic kidney disease, which further heightens the risk of hyperkalemia, especially when renin-angiotensin-aldosterone system inhibitors are used. Acute treatment for hyperkalemia may not be tolerated in the long term. Recent data for pati...
متن کاملHyperkalemia-induced complete heart block
Background: Potassium, as an extracellular ion, plays an important role in the electrophysiologic function of the myocardium and any change in extracellular concentration of this ion might have a marked impression upon myocyte electrophysiologic gain. High serum potassium levels are thought to impair pulse conduction in Purkinje fibers and ventricles more than that in the Atrio...
متن کاملHyperkalemia during spironolactone use in patients with decompensated heart failure.
BACKGROUND The incidence of hyperkalemia related to spironolactone use is low in stable heart failure; however, it has not been studied during decompensation. OBJECTIVE To evaluate the influence of spironolactone on serum potassium in decompensated heart failure (HF). METHODS In a cohort study, patients that had been hospitalized due to decompensated HF, with left ventricular ejection fract...

متن کاملExercise-Induced Hyperkalemia in Chronic Heart Failure Relation With Ventilation and Catecholamines
Background The exercise-induced rise in arterial potassium concentration ([K']a) may contribute to exercise hyperpnea and could play a role in exertional fatigue. This study was designed to determine whether the exercise-induced rise in [K']a is altered in patients with chronic heart failure (CHF) and whether physical training affects K' homeostasis. Methods and Results We evaluated 10 subjects...
