When it comes to the prevention of heart disease, women need to pay attention to their own special risks. And so do men. Surprisingly, even children and teens need to be aware- or at least the parents who want to keep them safe do. Thankfully, scientists have also made great leaps in figuring out the specific prevention strategies that work best for all. So now, knowledge is your best protection.
What Men Need to Know
According to the American Heart Association (AHA), at least half of the people who die suddenly from heart disease each year had no clue they were sick. Some think that half of all heart attacks strike out of the blue. Not true, insists Jennifer Mieres, a spokeswoman for the AHA. A 2004 study found that at least 90 percent of first heart attacks are caused by well-known problems like high cholesterol(胆固醇) or diabetes. “If you look closely,” says she, “you’ll almost always find a risk factor that was undiscovered, ignored, or not adequately treated.”
Lifestyle changes like adopting a healthy diet, getting out for regular exercise, avoiding tobacco, losing weight are the first line of defense.
What Women Need to Know
There are some special considerations for the women who are  healthy and want to make sure they stay that way. First, they shouldn’t smoke-no one should, but the habit is even harder on women’s heart than it is on men’s.
Women who find that they are at risk should talk to their doctor about taking a statin(他汀,药物名). Indeed, statins reduce the risk of heart disease, but there has been not enough evidence that they help high-risk women and it can’t guarantee the long-term safety. So it’s worth noting that a healthy diet and exercise also reduce cholesterol.
What Parents Need to Know
Last year, a study showed that overweight children and teens have arteries(动脉)that look like those of an average 45-year-old. New guidelines say these children should get a cholesterol test by age ten -- and even urge doctors to consider statins for those most at risk if nothing else works. The recommendations caused oppositions. Lifestyle changes such as diet and exercise are the best strategy, says Dr. Greer, a professor at the University of Wisconsin School of Medicine. Statins should be considered only for kids in danger.
