Cardiogenic shock: a review of contemporary approaches and ongoing challenges

Area of Science:

• Cardiology
• Critical Care Medicine

Background:

• Cardiogenic shock (CS) is a critical condition of inadequate cardiac output leading to organ failure.
• Understanding CS heterogeneity and classification is crucial for effective management.

Purpose of the Study:

• To review the definition, pathophysiology, classification, and management of cardiogenic shock.
• To highlight recent advances and evidence-based therapeutic approaches for CS.
• To identify current evidence gaps and ongoing trials in CS management.

Main Methods:

• Literature review focusing on cardiogenic shock.
• Analysis of recent advances in CS phenotypic heterogeneity and classification.
• Evaluation of evidence-based therapeutic interventions and mechanical circulatory support (MCS) devices.

Main Results:

• Emergent revascularization and microaxial flow pumps show survival benefits in specific CS cases (e.g., STEMI).
• Evidence for other medical therapies and MCS devices in CS remains limited.
• Significant gaps in evidence exist, with ongoing trials poised to inform future clinical practice.

Conclusions:

• Effective cardiogenic shock management requires understanding its complex pathophysiology and heterogeneity.
• Evidence-based treatments, while limited, offer survival benefits in select CS populations.
• Further research and ongoing clinical trials are essential to refine CS treatment strategies.
