Echocardiographic Correlates of Hyponatremia in Critically Ill Patients With Heart Failure.

ABSTRACT:

Background and objectives

Few data have examined cardiac function correlates of hyponatremia in heart failure (HF) patients. We examined the association between hyponatremia and echocardiographic parameters with outcomes among HF patients in the cardiac intensive care unit (CICU).

Methods

Retrospective analysis of 3,372 Mayo Clinic CICU patients with HF from 2007 to 2018 grouped according to admission serum sodium: severe hyponatremia (sodium <130 mEq/L, 6%), mild hyponatremia (sodium 130-134 mEq/L, 16%), normal (sodium 135-144 mEq/L, 78%). Echocardiographic findings and mortality were compared across groups.

Results

The median age was 71.8 years old, and 39% were females. Patients with hyponatremia had worse echocardiographic parameters reflecting left ventricular (L
