Prediction of acute-coronary-syndrome using newly-defined R-CHADS-VASc score among patients with chest pain.

Background: Chest-pain patients with no evidence of acute coronary syndrome might still be at risk for adverse outcomes. Adding renal function to the classic scoring of CHADS and CHADS VASC may improve risk stratification of chest-pain patients discharged from internal medicine wards after acute coronary syndrome (ACS) rule-out.

Methods: We accessed medical records of patients admitted to internal medicine wards during 2010-2016 and discharged following ACS rule-out.

Hyponatremia is associated with poor prognosis among patients with chest pain discharged from internal medicine wards following acute coronary syndrome-rule-out.

Background: Hyponatremia is the most common electrolyte abnormality observed in clinical practice. Among patients with acute coronary syndrome (ACS), serum sodium levels are inversely associated with mortality risk. We assessed associations of serum sodium level with ACS and mortality in patients with chest pain.
