Napping to a Healthier Heart?

1 Researchers say they have developed a simple test that can tell if a person with heart disease is
likely to suffer a heart attack.The test measures levels of a protein in the blood.The researchers say people
with high levels of this protein are at high risk of heart attack,heart failure or stroke.
2 Kirsten Bibbins-Domingo of the University of California in San Francisco led the team.For about
four years,they studied almost one thousand patients with heart disease.The researchers tested the heart
disease patients for a protein called NT-proBNP. Patients with the highest levels were nearly eight times more
likely than those with the lowest levels to have a heart attack,heart failure or stroke.
3 The researchers say the presence of high levels of the protein in the blood shows that the heart
muscle is under pressure in some way.The study involved mostly men,so the researchers could not say for
sure that the results are also true for women.They say the patients with the highest levels of NT-proBNP
were older and had other problems like diabetes or high blood pressure.
4 Other researchers say more studies are needed to confirm if knowing the protein levels of a heart
disease patient should affect that person’s treatment.They also would like to know if more aggressive
treatment could reduce the patient's chance of a heart attack or stroke.The study appeared in the
Journal of the American Medical Association.
5 Could a little sleep during the middle of the day reduce the risk of a heart attack?An unrelated
study earlier this month in the Archives of Internal Medicine suggests that the answer may be yes.In countries
like the United States,afternoon naps are mostly for children. But they are common for adults in
Mediterranean countries.And these countries generally have lower rates of heart disease.So scientists in the
United States and Greece wondered if naps could play a part.Twenty-three thousand healthy adults took part
in the study by Harvard University and the University of Athens.Those who took thirty-minute naps three
times a week had a thirty-seven percent lower risk of death from heart problems than people who did not take
naps.
6 The researchers say napping may improve heart health by reducing stress.They say the research
suggests that naps are especially good for working men.But they say not enough female subjects died during
the study to judge the benefits for women.

A:More Questions to Be Asked

Chest Compressions:Most Important of CPR
Cardiopulmonary resuscitation,or CPR,can save the life of someone whose heart has stopped.The condition is called cardiac arrest.The heart stops pumping blood.The person stops breathing.Without lifesaving measures,the brain starts to die within four to six minutes.CPR combines breathing into the victim's mouth and repeated presses on the chest.______(46)
However,a new Japanese study questions the usefulness of mouth-to-mouth breathing.The study was published in the British medical magazine,The Lancet.Doctors in Tokyo led the research.It examined more than four thousand people who had suffered cardiac arrest.In all the cases,witnesses saw the event happen.
More than one thousand of the victims received some kind of medical assistance from witnesses.Seven hundred and twelve received CPR.Four hundred and thirty-nine received chest presses only.______(47) The researchers say any kind of CPR improved chances of the patient's survival.But,they said those people treated with only chest presses suffered less brain damage.Twenty-two percent survived with good brain ability.______(48)
The American Heart Association changed its guidelines for CPR chest presses in 2005.______(49) Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson.He wrote a report that appeared with the study.Doctor Ewy thinks the CPR guidelines should be changed again.He said the heart association should remove rescue breaths from the guidelines.He argues that more witnesses to cardiac arrests would provide treatment if rescue breaths are not a part of CPR.He says this would save lives.
______(50) Cardiac arrest kills more than 300,000 people in the United States every year.The American Heart Association says about ninety-five percent of victims die before they get to a medical center.

______(58)
A:So far,we have not known exactly yet whether mouth-to-mouth breathing is really useless in CPR.
B:Only ten percent of the victims treated with traditional CPR survived with good brain ability.
C:CPR keeps blood and oxygen flowing to the heart and brain.
D:His studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.
E:It said people should increase the number of chest presses from fifteen to thirty for every two breaths given.
F:No mouth-to-mouth rescue breaths were given to them.

请阅读Passage 1，完成题：
Modern scientists divide the process of dying into two stages--clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived.
Biological death occurs when changes in the organism lead to the disintegration of vital cells and tissues. Death is then irreversible and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can be revived before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism, cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientists put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from its body. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped; clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into its body in the direction of the heart and started artificial breathing. After two minutes the monkey's heart became active once more. After fifteen minutes, spontaneous breathing began,and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.

One possible benefit of the experiment discussed in the passage is__________.
