Decoding interaction between mitochondria and endoplasmic reticulum in ischemic myocardial injury: targeting natural...

Area of Science:

• Cardiovascular Medicine
• Pathology
• Pharmacology

Background:

• Ischemic cardiomyopathy (ICM) results from irreversible myocardial injury, often linked to coronary artery disease.
• Inflammation plays a dual role in ICM, contributing to vascular damage while also offering potential cardioprotection.
• Coronary microvascular injury is a key pathological feature of ICM, driven by interconnected inflammatory and oxidative stress pathways.

Purpose of the Study:

• To review the mechanisms of vascular injury in ICM, focusing on the interplay of inflammation and oxidative stress.
• To explore the roles of endoplasmic reticulum dysfunction and impaired mitochondrial quality control in driving ICM-related vascular damage.
• To summarize the therapeutic potential of Chinese herbal medicines and their components in mitigating vascular injury in ICM.

Main Methods:

• Literature review of studies on ICM pathogenesis and treatment.
• Analysis of mechanisms involving inflammation, oxidative stress, endoplasmic reticulum stress, and mitochondrial dysfunction.
• Synthesis of research on the efficacy of traditional Chinese medicines in cardiovascular protection.

Main Results:

• Inflammation and oxidative stress interact to cause cell death and coronary microvascular injury in ICM.
• Dysfunctional endoplasmic reticulum and mitochondrial quality control significantly contribute to inflammation and oxidative stress.
• Chinese herbal medicines and their components demonstrate therapeutic benefits by enhancing vascular endothelial function and reducing vascular injury.

Conclusions:

• Understanding the intricate mechanisms of vascular injury in ICM is crucial for developing effective treatments.
• Targeting endoplasmic reticulum and mitochondrial pathways offers a promising therapeutic strategy for ICM.
• Traditional Chinese medicine presents a valuable resource for novel drug development in managing ICM-associated vascular damage.
