A new study finds, early morning heart attacks appear to be more serious than those that occur later in the day.
Researchers in Spain collected data on more than 800 heart attack patients.
They found those who suffered heart attacks between 6 a.m. and noon had 20 percent more damage to their heart tissue than those with attacks in the afternoon or night.
Doctors hope the findings will lead to more aggressive treatment and the development of drugs targeting these particular attacks.
