Seattle researchers have taken a key step toward beating back the world’s leading cause of death by regrowing damaged heart tissue in monkeys.

Scientists had long thought getting heart tissue to regenerate was impossible. But stem cell research began to raise hopes in the 1990s, and over the years, researchers like Chuck Murry of University of Washington Medicine’s cardiology division started to get some traction.

First came successes with rats, then with guinea pigs. Now Murry’s team has managed to repair heart tissue in an animal more closely related to humans: monkeys called pigtail macaques.

Your chances of surviving a sudden heart attack may depend on where you live; some American cities have survival rates five times higher than others. One difference can be 911 dispatchers.

If they coach someone over the phone to give CPR, the chance of surviving goes up. There's now a push to make it universal, but some cities are slow to implement the necessary training.

Becky Cole was eight months pregnant with her fourth child when she collapsed against the bathroom door. It was January 2011 in the Seattle suburb of Woodinville.

In 1974, CBS’ 60 Minutes declared Seattle was the best place in the world to suffer a heart attack. Nearly forty years later, the reputation persists – and experts are still claiming Seattle is tops in saving victims of cardiac arrest.
