Anchor lead: Are recent successes with CPR sustainable? Elizabeth Tracey reports
When bystanders initiate CPR during apparent heart attacks, more of those folks survive, recent studies show. While these results are very encouraging, Gordon Tomaselli, director of cardiology at Johns Hopkins, says the changing nature of heart disease may slow down the ability of CPR to sustain folks who have an out of hospital cardiac arrest.
Tomaselli: We have made a lot of progress in reducing cardiovascular mortality, cardiovascular disease incidence over the last twenty to thirty years. We’re now seeing kind of a resurgence, a lot of this has to do with rising rates of obesity, earlier onset of diabetes, and this may create a different form of heart disease. What we’re seeing is more heart failure as opposed to acute coronary disease, relatively speaking. Acute coronary disease still very prominent more than a million heart attacks a year, on top of that we’re seeing other forms of heart muscle weakness. :30
Tomaselli says public health efforts to prevent heart disease remain paramount. At Johns Hopkins, I’m Elizabeth Tracey.

Anchor lead: Learning CPR is simple and can save lives, Elizabeth Tracey reports
CPR works to save lives, two more recent studies in the Journal of the American Medical Association conclude. In Japan and North Carolina, where public education efforts were undertaken to improve rates of bystander-initiated CPR, almost twice as many people who had heart attacks survived to be discharged from the hospital. Gordon Tomaselli, director of cardiology at Johns Hopkins, says the message is clear.
Tomaselli: I would say learn CPR. Everybody should know CPR. It’s easy to learn it’s easy to keep proficient at, you may never need to use it but I think if you ever do need to use it you can save a life. That’s really the simple public health message. And I would also advocate for making sure there’s wide distribution of AEDs and that CPR is a requirement for graduation across all schools in this country. I think most people who can use a cell phone can use an AED. :25
Tomaselli adds that if you’re the sole responder to an apparent heart attack, make sure to call 911 before doing anything else. At Johns Hopkins, I’m Elizabeth Tracey.

Anchor lead: When more bystanders perform CPR more people survive, Elizabeth Tracey reports
Greater numbers of people are performing CPR when they witness a heart attack, with the result that almost twice as many heart attack victims are surviving to be discharged from the hospital, two recent studies in the Journal of the American Medical Association report. Gordon Tomaselli, director of cardiology at Johns Hopkins, comments.
Tomaselli: The survival for out of hospital cardiac arrest has been abysmal. What we know is that if you can support the circulation with good CPR until more advanced rescue gets there, chances of survival improves dramatically. One of the key things the AHA and others have done recently is to go to this philosophy of hands only CPR. Here we know that even if you just provide chest compressions that will move air in and out of the lungs but more importantly it will support the circulation until you can correct the abnormal cardiac rhythm. :32
So learn CPR, Tomaselli says. At Johns Hopkins, I’m Elizabeth Tracey.
