HEALTH REPORT – November 13, 2002: Aspirin1 After Bypass2 Surgery

By Jerilyn Watson


This is the VOA Special English Health Report.

A new study says the common drug aspirin greatly reduces life-threatening problems after an operation to replace
blocked blood vessels3 to the heart. The operation involves attaching new blood vessels onto the heart to bypass
blockages4 in the arteries5 that feed blood to the heart.

More than eight-hundred-thousand people around the world have this heart bypass surgery each year. The doctors
who carried out the study say giving aspirin to patients soon after the operation could save thousands of lives.

People usually take aspirin to control pain and reduce high body temperature. Doctors also advise some people to
take aspirin to help prevent heart attacks.

About ten to fifteen percent of bypass operations end in death or damage to the heart, kidneys6 or intestines7. The
new study said even a small amount of aspirin reduced such threats. The doctors said the chance of death for
bypass patients in the hospital who took aspirin fell by sixty-seven percent. They said this was true if the aspirin
was given within forty-eight hours of the operation.

The research was published in the New England Journal of Medicine. Dennis Mangano (mahn-GAH-no) heads
the Ischemia Research and Education Foundation, a nonprofit organization in San Francisco, California. Doctor
Mangano led a team that examined the records of more than five-thousand patients in seventeen countries who
had a heart bypass operation. Some patients received aspirin daily after the operation. Other patients did not
receive aspirin.

The doctors believe aspirin aids bypass surgery patients in two ways. They say it prevents blood from thickening
and forming clots8 that block blood vessels. They also believe aspirin reduces inflammation in blood vessels
which increases after an operation and can damage organs.

Several medical organizations already advise that patients receive aspirin soon after bypass surgery because it
helps the new blood vessels. However, many doctors have advised against aspirin both before and after
operations. They fear it may cause severe bleeding. Doctor Mangano’s team did not report that bleeding was a
problem.

However, the doctors said people who have stomach or intestinal9 bleeding or other bad reactions from aspirin
should NOT receive it after bypass surgery.
