Sepsis-induced cardiomyopathy: understanding pathophysiology and clinical implications

Area of Science:

• Critical Care Medicine
• Cardiology
• Immunology

Background:

• Sepsis is a life-threatening organ dysfunction due to infection, posing diagnostic and treatment challenges.
• Sepsis-induced cardiomyopathy (SIC) is a critical complication, characterized by ventricular dysfunction and reduced ejection fraction.
• Lack of standardized protocols for SIC leads to outcome disparities and limited statistical data.

Purpose of the Study:

• To comprehensively review the clinical manifestations, pathophysiological mechanisms, and treatment strategies for sepsis-induced cardiomyopathy (SIC).
• To explore the impact of SIC on sepsis prognosis by examining systemic factors and cellular signaling.
• To bridge current clinical practices with future research directions for SIC management.

Main Methods:

• Literature review of clinical manifestations, pathophysiology, and treatment strategies for sepsis-induced cardiomyopathy (SIC).
• Analysis of systemic factors and intracellular signaling pathways involved in SIC development.
• Discussion of clinical contexts influencing SIC occurrence and progression.

Main Results:

• Sepsis-induced cardiomyopathy (SIC) presents with ventricular dilation, reduced ejection fraction, and impaired contractility.
• Pathophysiological mechanisms involve complex interactions within myocardial and immune cells.
• Varied diagnostic criteria and treatment approaches contribute to significant outcome disparities.

Conclusions:

• Understanding SIC's pathophysiology is crucial for improving sepsis prognosis.
• Standardized diagnostic and treatment protocols are needed for sepsis-induced cardiomyopathy (SIC).
• Further research is required to address current challenges and guide clinical practice for SIC.
