Cardiogenic Shock With Acute Myocardial Infarction Among Older Adults in the United States.

Background: Characteristics and outcomes associated with cardiogenic shock (CS) with acute myocardial infarction (AMI) in older patients have not been well characterized.

Objectives: The purpose of this study was to investigate characteristics and outcomes of older patients admitted with CS with AMI.

Methods: We used the National Inpatient Sample database to evaluate clinical characteristics of hospitalizations, clinical outcomes, and health care utilization of hospitalizations of older patients ≥80 years with CS and AMI from 2003 to 2021.

Iatrogenic Cardiac Arrest During Thyroid Storm.

Introduction: Thyroid storm is a life-threatening condition with often severe cardiac implications. Correct treatment choices can vary depending on underlying cardiac systolic function.

Case Description: We present a case of a 47-year-old male with untreated Grave's disease who presented with a thyroid storm.

Optic-flow and egocentric-direction strategies in walking: central vs peripheral visual field.

The impact of a central or peripheral visual field loss on the vision strategy used to guide walking was determined by measuring walking paths of visually impaired participants. An immersive virtual environment was used to dissociate the expected paths of the optic-flow and egocentric-direction strategies by offsetting the walker's point of view from the actual direction of walking. Environments consisted of a goal within a forest, the goal alone, or the forest alone following a brief presentation of the goal.
