How the heart's unusual carbohydrate metabolism helps it stay strong

3d ago October 28, 2026 1 min read 📰 Medical Xpress
📋 Key Takeaway

Researchers have discovered that the heart uses both glucose and lactate simultaneously for energy, which is crucial for its function, especially in conditions like heart failure. This finding highlights the heart's unique metabolic capabilities, which could have implications for cardiovascular health. Understanding these mechanisms may inform medical practices in Iran, where cardiovascular diseases are prevalent.

🔍 Quick Context Guide
💡 Bottom Line: The heart's ability to use both glucose and lactate simultaneously could revolutionize treatment approaches for heart disease.

📰 What Happened

Researchers have discovered that the heart can utilize both glucose and lactate simultaneously for energy, which is vital for its function, particularly during heart failure. This unique metabolic capability of the heart may lead to new insights in treating cardiovascular diseases.

  • The heart uses glucose and lactate at the same time, unlike most human tissues.
  • This metabolic flexibility is crucial for maintaining energy flow during heart failure.

💡 Why It Matters

🇮🇷 For Iran: Understanding the heart's metabolism could lead to better healthcare strategies and treatments for the high rates of cardiovascular diseases in Iran.
🌍 Regional: Improved cardiovascular health can enhance overall public health in the region, potentially reducing healthcare costs.
🌐 International: These findings may influence global cardiovascular research and treatment protocols, highlighting the importance of metabolic studies.

📚 Background

Cardiovascular diseases are a major health concern worldwide, and understanding heart metabolism is crucial for developing effective treatments.

The information is based on scientific research, which is generally reliable but should be interpreted within the context of ongoing studies.

The heart is the hardest-working muscle in the body, beating constantly no matter what the body's energy reserves look like. Maintaining energy flow to the heart is a complex process that can break down during common but severe cardiovascular disease conditions like heart failure. Researchers previously knew that heart muscle seems to do an unusual metabolic trick to always get enough energy: using two carbohydrate energy sources, glucose and lactate, at the same time. In most human tissues, using more glucose makes it harder to use lactate, and vice versa, but the heart is different.
