7. It's not unusual for people to feel a pain directly behind their breastbone

and think that it can't be their heart, because everyone knows that is in the left side

of the chest.

It's not unusual, but it's wrong. While people think that the problem is in their

airways, it is often (36) their heart, Helmut Gohlke of the German Association

says.

The (37), known as angina (心绞痛), reveals itself as pain behind the

breastbone. It's an illness where the blood (38) to the heart muscle is restricted.

If not (39) and treated in a timely manner, it can lead to a heart attack and

death.

The pain behind the breastbone radiates mostly to the throat, the upper

abdomen and the left arm. It is (40) described as a dull, wearing feeling of

compression, says Christian Hamm of the German Heart Association. Women

often (41) about lack of air. All those suffering say the pain comes suddenly and

Steady forms of angina are (43) by exertion (努力，费力), like physical work

fat is bad for you. On that, almost everyone agrees. It is just possible,

though, that almost everyone is wrong. In fact, getting fat may be a mechanism

that protects the body. The health problems (36) with fatness may not be

caused by it but be another consequence, another symptom, of overeating.

That is the heretical (异端邪说的) (37) of Roger Unger and Philipp Scherer.

They have been (38) the science of what has come to be known as metabolic

syndrome (代谢综合症). This is a host of symptoms such as high blood pressure,

insulin (胰岛素) resistance and fatness that seem to increase the (39) of heart

disease and strokes and liver disease. Metabolic syndrome is (40) in one-sixth

of the American population.

"Syndrome" is the medical term for a (41) of symptoms whose common

cause is not properly understood. The symptom of metabolic syndrome that
