🧠❤️ 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. 🎧💡
