Hypertension Drugs Found to Cut Risk of Stroke

Australian doctors declared Monday that a cocktail of simple antihypertensive drugs can lower the risk of
patients suffering a repeat stroke by more than a third.This is the result of their research.The research,
presented at a medical conference in Italy over the weekend,has been valued highly as a major breakthrough
in stroke prevention.
Strokes kill 5 million people a year,and more than 15 million suffer non-fatal strokes that often leave
them with useless limbs,slurred speech and other serious disabilities.One in five stroke survivors goes on to
have a second,often fatal,stroke within five years of the first.
An international six-year study of 6,100 patients directed from Sydney University found that by taking
two blood pressure-lowering drugs,the risk of secondary strokes can be reduced by up to 40 percent.Even
taking one of the commonly available drugs can cut the risk by a third,the study said.The drugs are the diu-
retic indapamide( 吲达帕胺）and the ACE inhibitor perindopril , better known by its brand name Coversyl.
The combination was effective even in patients who did not have high blood pressure,the researchers said.
They even found that the risk of another stroke could be cut by three quarters among the one-in-ten patients
who had suffered a cerebral hemorrhage（出血）, the worst type of stroke , where there is direct bleeding into
the brain.
Stephen McMahon,who presented the research at the Milan congress of the European Society of
Hypertension,said about 50 million people were alive who had suffered at least one stroke."If most of those
patients were able to get access to this treatment,it would result in maybe the avoidance of haff a million
strokes a year,"the professor told Australia's ABC Radio.
McMahon said doctors had long known that lowering the blood pressure of those with hypertension could
help prevent strokes."What we have shown for the first time is that it does not really matter what your blood
pressure is;if you have had a stroke,then lowering blood pressure will produce large benefits,to begin
with一even for people whose blood pressure is average or below average,"he said.
McMahon said the Milan gathering had heralded the research as a"major breakthrough in the care of
patients with strokes一perhaps the biggest step forward that we have made in the last couple of decades."
选项 Taking two blood pressure-lowering drugs may produce________less risk of secondary stroke than taking only one such drug.
A:three quarters
B:nearly four tenths
C:one fifth
D:about one fourteenth
答案D
解析由文章第二段第二句“One in five stroke survivors goes on to have a second, often fatal, stroke within five years of the first.”可知，中风以后存活的病人，5人中有1人在第一次中风后5 年内会再次中风，而且常常是致命的，故C为正确答案。
由文章第三段的内容可知，服用两种降压药继发中风的危险性可减少40%；单服一种 药，其危险性降低1/3，即约33%。可见服用两种药比服一种药可减少大约7%，即大约1/14 的危险性。
第二段第一句说非致命的中风常造成病人四肢残废、语言障碍以及其他严重残疾。B、 C、D三项符合题意（D项的面部麻痹自然属于严重残疾之一），而A项“习惯性失眠”，则不应属 于中风的后遗症，故A是正确答案。
由文章第四段第二句“'If most of those patients were able to get access to this treatment , it would result in maybe the avoidance of half a million strokes a year,’"可知，如果大多数病人有机 会进行这样治疗的话，每年就可以避免50万次中风的发生，故B为正确答案。
由文章倒数第二段的内容可知，血压高低并不重要，只要你得了中风，降低血压就有很 大益处，即使血压正常或低于正常值也是如此，故D为正确答案。
