Aspirin for heart attack: Chew or swallow?
Immediate first aid works to minimize blood clotting triggered by plaque ruptures
How should you take aspirin for a heart attack? You've always been healthy, but you seemed to run out of steam at your wife's 60th birthday dinner last week. And now your chest feels heavy, as if you're in a vise. You take some antacids, even though it's 7:00 a.m. and you haven't even had breakfast. But you get no relief, and the pain is spreading to your jaw and shoulder. You call your wife, who takes one look at you and rushes to the phone. After calling 911, she brings you an aspirin and some water.
Your wife got it right: You may be having a heart attack, and you need to get to the hospital fast. You also need to get some aspirin into your system quickly — but should you chew the tablet or swallow it?
If you suffer from cardiac arrest, help is only a 911 call away. Paramedics can use defibrillators to shock your heart back to a normal rhythm. But unfortunately, every minute you spend waiting for their arrival reduces your chance of survival by 10%. Help may soon be closer than your local paramedic and it may come from an unlikely source — someone without medical expertise.
Until recently, witnesses to someone having a cardiac arrest were limited in the help they could provide — calling 911 and performing CPR (cardiopulmonary resuscitation). Now, portable automated defibrillators about the size of a laptop computer are available. These devices not only deliver a shock to restore a regular heartbeat, they also determine whether a shock is really needed, making it possible and safe for people without medical training to use.
Statins may offer a long-term legacy benefit
Cholesterol-lowering statins seem to have long-lasting benefits against heart disease, according to a 20-year follow-up of a landmark Scottish study.
In the original study, published in 1995, more than 6,500 middle-aged men with high levels of harmful LDL cholesterol took either 40 milligrams of pravastatin (Pravachol) or a placebo daily for an average of nearly five years. For the follow-up, published in the March 15 Circulation, researchers used electronic medical records to analyze health-related events among the same men over the following two decades. They also tracked the men's use of statins after the original study ended. After five years, more than a third of the men in both groups were taking statins, but no further data on statin use was available after that.
When chest pain strikes: What to expect at the emergency room
Here's a rundown of the likely chain of events after you call 911.

Every 43 seconds, someone in the United States has a heart attack. If one day that someone is you or a loved one, it may be helpful to know what's likely to happen, both en route to the hospital and after you arrive.
Avoiding atherosclerosis: The killer you can't see
Be proactive to ward off clogged arteries that can lead to heart attack, stroke, and even death.

Most people don't spend a lot of time thinking about atherosclerosis. After all, you can't see any buildup of waxy plaque that may exist in your arteries, and the disease doesn't make itself known until it's advanced. "It can progress for decades before you have symptoms like chest discomfort or shortness of breath," explains Dr. Ron Blankstein, a cardiovascular imaging specialist and preventive cardiologist at Harvard-affiliated Brigham and Women's Hospital.
Yet atherosclerosis quietly and invisibly puts many millions of people at risk for heart attack, stroke, leg amputation, disability, and even death.
A more personalized approach to treating high cholesterol

Cholesterol, the waxy, fatlike substance that contributes to heart attacks and strokes, is among the best-known contributors to cardiovascular disease — and with good reason. For decades, doctors have recommended blood cholesterol testing, often during annual checkups. Nearly one in three American adults has high levels of LDL, the most harmful type of cholesterol. Expert advice on managing this common problem now takes a more personalized approach, according to updated guidelines released by the American College of Cardiology and American Heart Association last November.
"The new guidelines really codify and support what many preventive cardiologists already do," says Dr. Jorge Plutzky, director of preventive cardiology at Harvard-affiliated Brigham and Women's Hospital. They tailor treatment based not just on LDL values but also a person's overall risk, he explains.
