Healthy Living: Growing Blood Vessels

Heart disease can be caused by a narrowing of the arteries carrying blood to the heart.

Patients with peripheral artery disease, or PAD, have arterial blockages in the legs.

But what if the body had the ability to grow new vessels to improve blood flow?

In Healthy Living, Courtney Hunter explains how it could be medicine’s next big thing.

Researchers say they envision the first treatments will target ischemic tissues in the legs and later the heart.

Eventually this process might be used to treat eye diseases like macular degeneration caused by leaky blood vessels.
