Doctors are less likely to perform a potential life-saving procedure on some of the oldest heart attack patients.
Researchers studied the hospital records of nearly 470,000older patients who suffered their first heart attack.
Those who were 85 and older were less likely to receive angioplasty or stents which can open blocked arteries.
This is compared to adults ages 75 to 84.
But older adults were more likely to survive a heart attack if they had the procedure regardless of age.
