CHA DS -VASc score and clinical outcomes of patients with chest pain discharged from internal medicine wards following acute coronary syndrome rule-out.

Background: Chest-pain patients deemed safe for discharge from internal medicine wards might still be at risk for adverse outcomes.

Hypothesis: CHA DS -VASc score improves risk stratification of low-risk chest-pain patients discharged after acute coronary syndrome (ACS) rule-out.

Methods: We accessed medical records of patients who were admitted to internal medicine wards at a single medical center during 2010-2016 and discharged following an ACS rule-out.

Iodinated Contrast Media Allergy in Patients Hospitalized for Investigation of Chest Pain.

Background: Iodinated contrast media (ICM) allergy may entail severe adverse events in patients who undergo percutaneous coronary intervention (PCI). Premedication protocols and low-osmolality contrast media have been thought to improve the outcomes of these individuals.

Objective: The objective of this study was to assess the prevalence and severity of allergic reactions during PCI in patients admitted for investigation of chest pain.
