Association of potassium disorders with the mode of death and etiology in patients with chronic heart failure: the INCOR-HF study.

ABSTRACT: Observational studies suggest a U-shaped association between serum potassium (K⁺) levels and mortality in patients with chronic heart failure (CHF). However, the mode of death in patients with HF and K⁺ disorders remains speculative. To investigate the association between potassium disorders and the mode of death in patients with CHF. A retrospective cohort of 10,378 CHF outpatients was analyzed over an average of 3.28 ± 2.5 years. Kaplan-Meier method, Cox proportional hazards regression models, Poisson regression models adjusting for confounders, and e-value determination (e' > 1.6) were used to observe associations between potassium disorders and outcomes. Chagas etiology (p < 0.01) and triple HF therapy (p < 0.01) were associated with hyperkalemia. Atrial fibrillation was associated wit
