NEW YORK (WABC) -- You may want to talk to your doctor before taking aspirin on a regular basis to prevent a heart attack.
Studies published in the New England Journal of Medicine showed a massive sample of older people in Australia who took a daily low-dose aspirin didn't necessarily see any health benefits.
In fact, those who took the aspirin appeared to bleed internally more than those who took a placebo.
The researchers say the best course of action would be to consult a doctor.
The research was based on nearly 20,000 people with a median age of 74, studied for five years.
