Abstract
Sepsis, an infection‑triggered systemic inflammatory response syndrome, ranks as the third leading cause of death worldwide due to its high incidence and mortality. Sepsis‑induced myocardial dysfunction (SIMD) is a frequent and serious complication that notably increases patient morbidity and mortality. The underlying pathophysiology of SIMD involves a complex interplay of inflammation, oxidative stress, mitochondrial impairment and apoptosis, yet no effective therapies have been established. Thus, uncovering the molecular mechanisms of SIMD, identifying novel therapeutic targets and developing efficacious agents are key. For centuries, natural products have been used in traditional medical systems across China and Asia to manage cardiovascular disease. These compounds can confer cardioprotection by modulating inflammatory pathways, decreasing oxidative stress, inhibiting apoptotic cell death and improving mitochondrial function. The present review aimed to summarize the clinical manifestations and pathophysiology of SIMD and how natural products exert their protective effects. The present study aimed to explore structure‑activity relationships and highlight key molecular targets and representative natural product binding affinities for SIMD‑related proteins. In summary, the present study presents a comprehensive overview of the multi‑targeted strategies employed by natural products against SIMD and provides guidance for the discovery of SIMD‑focused dietary supplements and lead compounds, laying the groundwork for future translational research.
