Septic Shock and Myocardial Dysfunction

Abstract

Cardiac dysfunction in sepsis is strongly linked to increased mortality. The pathophysiology of sepsis-induced Myocardial dysfunction is multifaceted, involving impaired myocardial circulation, direct myocardial depression, and mitochondrial dysfunction. Recent studies have emphasized that mitochondrial dysfunction plays a crucial role in sepsis-induced Myocardial dysfunction. Various medications have been utilized to treat sepsis, aiming to prevent and address sepsis-induced cardiomyopathy. Nevertheless, these treatments have not significantly improved patient outcomes. This underscores the need for new therapeutic strategies that target the specific mechanisms of sepsis-induced myocardial dysfunction. Monitoring sepsis-induced cardiac dysfunction is essential, as it significantly impacts the prognosis. To effectively monitor this condition, clinicians use a combination of clinical assessments, hemodynamic monitoring, and echocardiography and biomarkers. Integrating these methods allows for a comprehensive understanding of cardiac function, enabling timely adjustments to treatment plans. Patients with this condition will benefit from established sepsis and septic shock treatments. However, apart from general management with vasopressors, inotropes, and fluid resuscitation, there is limited data and a lack of evidence regarding more specific treatments. This chapter provides an overview of the current understanding of the pathophysiological processes involved in sepsis-related cardiac dysfunction and the impact of monitoring and current management in sepsis-induced Myocardial dysfunction.
