Background Limited, contradictory data exist regarding the effect of hyperkalemia on both
short-and long-term all-cause mortality among hospitalized patients with heart failure (HF) …

OBJECTIVE: Most HF patients are older adults, yet the associations of low serum potassium
and outcomes in these patients are unknown. We studied the effect of low serum potassium …

Dyskalemia (hypokalemia and hyperkalemia) is a common comorbidity of heart failure (HF).
Although dyskalemia is associated with poor prognosis, different prognostic impacts of hypo …

Potassium levels are often abnormal in patients with heart failure (HF) and have a
detrimental effect on clinical outcome. We evaluated potassium levels in a real-world cohort …

Background: Abnormalities in serum potassium levels have been associated with variable
mortality risk among hospitalized patients with heart failure (HF). We aim to use a large …

Background: Hyper-and hypokalemia are common in heart failure (HF) and associated with
worse outcomes. Normal values are established in the general population (3.5-5.0 mmol/L) …

Aims Medication prescribed to patients suffering from chronic heart failure carries an
increased risk of impaired potassium homeostasis. We examined the relation between …

BACKGROUND In patients hospitalized with heart failure (HF) exacerbations, physicians
routinely supplement potassium to maintain levels≥ 4.0 mEq/L. The evidence basis for this …

Aims Potassium homeostasis is essential for normal myocardial function, and low serum
potassium may cause fatal arrhythmias. However, the association of low potassium and long …

Aim We investigated the prognostic significance of serum potassium abnormalities at
discharge in patients hospitalized for acute heart failure (AHF). Methods and results In a …
