Better CPR
CPR is the standard way to resuscitate patients, but often, rescuers can't physically press hard enough and long enough to save a life. Now, there may be a better way to perform CPR, and it doesn't require any work on your part.

Growing New Blood Vessels
Atherosclerosis: It's what will ultimately kill most of us. It's the build-up of plaque in the arteries, leading to stroke, heart attack, and eventually death. When arteries in the legs become blocked -- a condition called peripheral vascular disease -- getting around can be painful. Now, breakthrough research is allowing patients to grow new, healthy blood vessels!

Help for Blood Pressure
It's a condition that can lead to stroke, heart failure, kidney disease and even death. We're talking about high blood pressure. Until now, medications have been the only way to control it. But an investigational device may offer some patients a welcome alternative.

High-Tech Heart Help
Also in the high-tech virtual arena is the wireless technology doctors are using to virtually monitor implanted cardiac defibrillator patients, where the patient doesn’t have to leave home to have a check-up.

Hugging Hearts
More than 300,000 people die every year from cardiomyopathy, a weakening of the heart muscle that causes it to enlarge and fail. Medication won’t always stop the disease, leaving patients with very few options. Now, researchers are testing a new device that could give heart patients a new lease on life.
