Key result
Pretreatment with Sterofundin reduces infarct size and preserves cardiac function after MI in mice.
Why the study?
Sterofundin is widely used in intensive care and corrects key post-MI imbalances, but its cardioprotective effects and mechanisms after MI are largely unknown.
Does pretreatment with the electrolyte solution sterofundin reduce myocardial damage and improve cardiac performance post-myocardial infarction in mice?

Prophylactic administration of the electrolyte solution sterofundin reduces myocardial damage and preserves cardiac function following myocardial infarction in mice, likely via upregulation of autophagy.
Background: Sterofundin (SF) is one of the most widely used electrolyte solutions in almost all areas of medicine, with particular importance in intensive care. It provides powerful correction of acid-base imbalances, ion fluctuations, and impaired energy metabolism, which are the three most important characteristics after myocardial infarction (MI). However, whether and how SF protects the heart from post-MI damage are largely unknown. Methods and Results: Pretreating mice with SF before MI surgery reduced the number of reactive oxygen species (ROS)-positive and TUNEL-positive cells. As a result, the infarcted area cardiac fibrosis in the MI mice was reduced and cardiac performance in the MI mice improved. Moreover, RNA-seq analysis demonstrated that SF caused the gene expression profile of MI mice to shift toward that of sham mice, with a significant decrease in apoptosis-, ROS-, and inflammation-associated gene enrichment. RNA-seq analysis also demonstrated that SF induced the upregulation of autophagy-associated gene enrichment. Western blotting confirmed the RNA-seq analysis results, showing that SF induced the upregulation of an autophagic flux. When the autophagic flux was blocked with the autophagy inhibitor 3-methyladenine, the protective effect of SF was reduced. Conclusion: SF protects the heart from post-MI damage, and one of the underlying mechanisms could be its autophagy modifications. This study is the first to reveal a previously unrecognized role of electrolyte solutions in post-MI intensive care.

Chen et al. (2025) studied Myocardial Infarction. Sterofundin vs. MI surgery without Sterofundin (MI group) and Sham surgery was evaluated on Infarcted area, reactive oxygen species, and cardiac performance (EF%, FS%, LVEDD, LVESD) (p=<0.05). Pretreating mice with the electrolyte solution Sterofundin before myocardial infarction significantly reduced infarct size, reactive oxygen species, and cardiac fibrosis while improving cardiac performance through autophagy modification.
