Aspirin and Heart Attack

Researchers have announced the results of two studies on the health effects of the drug aspirin (阿司匹林). One study shows aspirin can sharply reduce the chance that a healthy, older man will suffer a heart attack.

The study offered two new results from earlier findings. It said taking one aspirin pill every other day helped only healthy men over the age of fifty. It also said aspirin gave the greatest protection against heart attacks to men with low blood cholesterol(胆固醇)levels.

Earlier studies showed that aspirin reduced the chance of heart attacks in men with heart dis- ease. But there was no proof that aspirin would do the same for healthy men.

Researchers in the United States began a major aspirin study in the early 1980s. It includes 22000 healthy male doctors. All were between the ages of forty and eighty-four. More than 11000 of the doctors took one aspirin pill every other day. Each pill contained 325 milligrams of aspirin. The other 11000 doctors took a harmless pill that contained no drug. The men did not know which kind of pill they were taking.

The doctors who took aspirin suffered 44 percent fewer heart attacks than those taking the harmless pill. 139 men who took aspirin suffered attacks. Ten of them died. 239men who did not take aspirin suffered heart attacks. Twenty-six of them died. The researchers said the doctors’ study provided clear proof that taking aspirin can prevent a first heart attack in healthy, older men. They said, however, the results do not mean every man over the age of fifty should take aspirin. They said aspirin cannot help men who do not eat healthy foods, who smoke cigarettes and who are fat. The researchers said men who think they would be helped by taking aspirin should talk with their doctors first.
