Effect of Hyponatremia (<135 mEq/L) on Outcome in Patients With Non–ST-Elevation Acute Coronary Syndrome

Hyponatremia is associated with adverse outcomes in patients with heart failure and ST-elevation myocardial infarction (STEMI). We evaluated the effect of hyponatremia on outcomes in patients with suspected acute coronary syndrome and non-STEMI. All patients had a sodium level determined at time of...
