# Distributive shock in cardiac intensive care unit patients

## TL;DR

This paper reviews how to diagnose and manage distributive shock in cardiac ICU patients, emphasizing its differences from cardiogenic shock.

## Contribution

The paper provides a detailed review of the unique challenges in managing distributive shock in cardiac ICU settings.

## Key findings

- Distributive shock is associated with worse outcomes in out-of-hospital cardiac arrest patients.
- Distinguishing between cardiogenic and distributive shock is essential for effective treatment.
- Immune system dysregulation is a common feature in both shock types.

## Abstract

Shock is a life-threatening condition of circulatory failure. Mixed shock is observed in approximately 24.5 % of patients with cardiogenic shock. In cases of out-of-hospital cardiac arrest, outcomes are worse when the predominant shock type is distributive rather than cardiogenic. Thus, distinguishing between cardiogenic and distributive phenotypes is crucial for appropriate management. A dysregulated immune response has been observed in both. This review article details the pathophysiology, diagnostic challenges, and management of distributive shock when encountered in a cardiac intensive care unit.
