One of the greatest killers in the Western world in heart disease. The death rate (率) from the disease
has been increasing at an alarming speed for the past thirty years. Today in Britain, for example, about
four hundred people a day die of heart disease. Mdical experts know that people can reduce their chances
of getting heart disease by exercising regularly, by not smoking, by changing their diets, and by paying
more attention to reducing stress (压力) in their work.
However, Western health-care systems are still not paying enough attention to the prevention of the
disease. There is a need for more programs to educate the public about the causes and prevention of heart
disease. Instead of supporting such programs,however, the U.S. health-care system is spending large sums
of money on the surgical (外科的) treatment of the disease after it develops. This emphasis (强调) on
treatment clearly has something to do with the technological advances that have taken place in the past ten
to fifteen years. In this time,modern technology has enabled doctors to develop new surgical techniques.
Many operations that were considered impossible or too risky (有风险的) a few years ago are now
performed every day in U.S.hospitals. The result had been a huge increase in heart surgery.
Although there is no doubt that heart surgery can help a large number of people, some people point out
that the emphasis on the surgical treatment of the disease has three clear disadvantages. First, it attracts
interest and money away from the question of prevention.Second, it causes the costs of general hospital
care to rise. After hospitals buy the expensive equipment that is necessary for modern heart surgery, they
must try to recover the money they have spent. To do this, they raise costs for all their patients, not just
those patients whose treatment requires the equipment. The third disadvantage is that doctors are
encouraged to perform surgery-even on patients for whom an operation is unnecessary-because the
equipment and expert skills are there. A government office recently stated that major heart surgery was
often performed even though its chances of success were low. In one type of heart surgery, for example,
only 15 percent of patients improved their conditions after the surgery. However,more than 100,000 of these
operations are performed in the United States every year.
