Cardiogenic shock: evolving definitions and future directions in management

Area of Science:

• Cardiology
• Critical Care Medicine

Background:

• Cardiogenic shock (CS) is a complex, high-mortality condition.
• Its pathophysiology involves a detrimental cycle of cardiac and systemic decompensation.
• Current understanding suggests early, aggressive support is vital for survival.

Purpose of the Study:

• To review the pathophysiology, clinical features, and trial data of CS.
• To develop a contemporary model of CS as a systemic process.
• To propose an algorithmic approach for acute CS management.

Main Methods:

• Literature review of pathophysiology, clinical features, and clinical trial data.
• Construction of a systemic model of CS.
• Development of an algorithmic approach for management.

Main Results:

• CS is characterized by maladaptive compensatory mechanisms.
• Prompt, tailored medical and mechanical support are required for optimal outcomes.
• An algorithmic approach integrating clinical and hemodynamic data is proposed.

Conclusions:

• CS management requires a contemporary model viewing it as a systemic process.
• An algorithmic approach can guide tailored support for optimal patient outcomes.
• Early and robust cardiac support is critical for survival in CS.
