Objectives: This study investigated 1-year incidence and predictors of dyskalemia (dysK)
and its outcome associations in heart failure with preserved ejection fraction (HFpEF), HF …

Potassium (K+) is the most abundant cation in humans and is essential for normal cellular
function. Alterations in K+ regulation can lead to neuromuscular, gastrointestinal, and …

Background: The relationship between serum potassium, mortality, and conditions
commonly associated with dyskalemias, such as heart failure (HF), chronic kidney disease …

Background Data on the true burden of hyperkalemia in patients with heart failure (HF) in a
real‐world setting are limited. Methods and Results Incidence rates of hyperkalemia (first …

Background—Little is known about the effects of hypokalemia on outcomes in patients with
chronic heart failure (HF) and chronic kidney disease. Methods and Results—Of the 7788 …

BACKGROUND: Compared with serum potassium levels 4–5.5 mEq/L, those< 4 mEq/L have
been shown to increase mortality in chronic heart failure (HF). Expert opinions suggest that …

Potassium disorders are common in patients with kidney disease, particularly in patients
with tubular disorders and low glomerular filtration rate. A multidisciplinary group of …

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 …

Predictors of hyperkalemia in patients with cardiovascular disease (CVD; defined as patients
with hypertension and heart failure) and associated chronic kidney disease (CKD) are not …

Objectives: We explored the incidence and predictors of hyperkalemia in a broad population
of heart failure patients. Background: When used in optimal doses to treat patients with heart …
