🧠➡️❤️ Rewiring the Heart: When the Vagus Nerve Saves Cardiac Function

🧠❤️ Rewiring the Heart—Literally   A striking Science Translational Medicine study shows that early reconnection of the right vagus nerve to the heart preserves ventricular mechanics, synchrony, and myocardial health—even when only ~20% of vagal fibers regenerate. 🧵🫀   Using a clinically relevant minipig model, the authors demonstrate that loss of parasympathetic input drives oxidative stress, inflammation, and premature cardiac aging—while targeted nerve repair reverses these pathways, independent of heart rate. 📉➡️📈   Implications: thoracic surgery, heart–lung transplantation, and the future of autonomic cardioprotection. Sometimes, saving the heart means listening to the nerve. 🎧💡   📖 Science Translational Medicine, Dushpanova et al., 2025
