Based on a telephone survey of about 72, 000 people in 2005, only about 1 in 4 Americans knows the warning signs of a heart attack and what to do first, according to a new government report.That’s a decline from the last survey in 2001, which showed that nearly 1 in 3 were well informed.
The study’s lead author, Dr.Jing Fang, called public awareness in the new survey“alarmingly low”.Fang is with the Center for Disease Control and Prevention, which surveyed residents of 13 states and District of Columbia.
Heart attack warning signs can include one or more of the following:shortness of breath, pain or discomfort in the chest, discomfort in the arms or shoulders, a feeling of weakness or light headedness, and discomfort in the jaw, neck or back.Chest pain is the most common symptom.Women are more likely than men to experience some of the other symptoms, particularly shortness of breath and back or jaw pain, according to the American Heart Association.Anyone experiencing these symptoms should call 911, the heart association advises.In America, the groups best informed of heart attack warning signs, and what to do, tended to be white, highly educated women.Also scoring well were residents of West Virginia, which has some of the nation’s highest heart attack death rates.
Each year more than 900, 000 Americans suffer heart attacks, about 157, 000 of them fatal(致命的).About half the deaths occur within an hour of the symptoms appearing, experts say.Because different people experience different symptoms, it’s important to be aware of all of them, doctors say.
Of course, knowing is not the same as doing.Although most of those who got the heart attack symptoms right said they would call 911, other studies show that only about half of heart attack victims go to a hospital by ambulance, Rosamond noted.
Patients’s concerns about lack of health insurance or other matters may explain why so few went to a hospital, said Rosamond, who was not involved in the new study.
