Dr. Jonathan Kim from Emory Cardiovascular Specialists at Emory Saint Joseph’s Hospital answers a reader’s question about how running a marathon can affect your heart.
Q: Is running a marathon dangerous for my heart?
A: Currently, there is no definitive data that implicates marathon running as dangerous for your heart. In fact, for those healthy enough to train for and run a marathon, there are clearly both mental and physical benefits. If you are interested in running a marathon, first consult your doctor or sports cardiologist to ensure you are physically fit enough to embark on a training regimen, and then go out and enjoy your long runs.
