Is Your Heart Marathon Ready?

As both an avid runner and a cardiologist, I've closely followed research on endurance running and its impact on the heart. While some studies suggest that long-distance running can lead to plaque buildup and scarring in the heart, others have shown that marathoners may be better equipped to handle heart disease. 

It's important to understand that long-distance running is a demanding activity that can put stress on multiple organs. A 2012 study found that many marathon runners experience temporary enlargement of the heart's right atrium and ventricle, as well as elevated biomarkers indicating heart stress. While most runners can recover from these effects, a small percentage may be at risk for scarring, which can lead to heart failure. 

However, another study, tracking runners and non-runners over two decades, found that regular running can significantly reduce the risk of death. Even as runners decreased their weekly mileage over time, they continued to reap health benefits. 

So, what should runners do? While there are risks associated with endurance running, the benefits generally outweigh them. The key is to participate safely. 

Here's a plan to help you stay safe: 

1. Get a checkup: Before increasing your mileage, consult with your doctor to assess your heart health and identify any potential risk factors. 

1. Listen to your body: Pay attention to any symptoms like chest pain, excessive shortness of breath, or unusual fatigue. If you experience these, stop training and seek medical advice. 

1. Train gradually: Increase your mileage and intensity gradually to give your body time to adapt. 

1. Stay hydrated: Proper hydration is essential for heart health and overall performance. 

By following these guidelines, you can safely enjoy the benefits of endurance running and minimize the risks.
