Researchers have announced the result oftwo studies on the health effects of the drug aspirin．One study shows aspirin cansharply reduce the chance that a healthy, older man will suffer from a heartattack．

The study offered two new results fromearlier findings, It said taking one aspirin pili every other day helped onlyhealthy men over the age of fifty．It also said aspirin gave the greatest protection against heartattacks to men with low blood cholesterol（胆固醇）levels．

Earlier in the United States began a majoraspirin study in the early 1980s．It included 22,000 healthy men doctors．Ail were between the ages of forty and eighty-four．More than 11,000 of the doctorstook a harmless pill that contained no drug．The men did not know which kind of pill they weretaking．

The doctors who took aspirin suffered 44%fewer heart attacks than those taking the harmless pill．139 men who took aspirinsuffered from heart attacks．Ten of them died．239 men who did not take aspirin suffered from heart attacks．Twenty-six of them died．

The researchers said the doctors' studyprovides clear proof that taking aspirin can prevent a first heart attack inhealthy, older men．Theysaid, however, the result does not mean every man over the mage of fifty shouldtake aspirin．Theysaid aspirin couldn't help men who do not eat healthy foods, who smokecigarettes and who are fat．The researchers said men who think they wou3d be helped by takingaspirin should talk with their doctors first．
