This One Thing Makes Your Heart Younger

Hearts get ‘younger,’ even at middle age, with one lifestyle choice 

(Patti Neighmond, NPR) Eventually it happens to everyone.

As we age, even if we’re healthy, the heart becomes less flexible, more stiff and just isn’t as efficient in processing oxygen as it used to be. In most people the first signs show up in the 50s or early 60s.

And among people who don’t exercise, the underlying changes can start even sooner.

“The heart gets smaller — stiffer,” says Dr. Ben Levine, a sports cardiologist at University of Texas Southwestern Medical Center.

Think of the heart muscle as a rubber band, Levine says. In the beginning, the rubber band is flexible and pliable. But put it in a drawer for 20 years and it will emerge dry and brittle.

“That’s what happens to the heart and blood vessels,” he says. And down the road, that sort of stiffness can get worse, he notes, leading to the breathlessness and other symptoms of heart failure, an inability of the heart to effectively pump blood to the lungs or throughout the body.

Fortunately for those in midlife, Levine is finding that even if you haven’t been an avid exerciser, getting in shape now may head off that decline and help restore your aging heart.

He and his colleagues published their recent findings in the American Heart Association’s journal, Circulation.

The research team recruited individuals between the ages of 45 and 64 who were mostly sedentary but otherwise healthy.

Dallas resident Mae Onsry, an accounts payable manager, was 62 at the time. Raising two children and working full time, she says, she never had the flexibility to fit in exercise, although she knew it was important for her health.

“I have my hobbies,” says Onsry, including ballroom dancing and gardening. But it was nothing routine, nothing “disciplined,” she says … Read the full story at MPR News.
