Heart attacks which happen in the morning are associated with more serious conditions compared to those occurring later in the day, a new study says.

The analysis of data on 811 patients with a myocardial infarction showed the injury to be more extensive in those who had a morning heart attack.

According to the report published in the British journal Heart, patients who had experienced a heart attack between 6:00 am and noon had a 21 percent larger infracted lesion in comparison to those having a cardiovascular event between 6:00 pm and midnight.

The new findings supported the hypothesis that the body's natural clock called circadian rhythm influences the heart in many ways by controlling blood pressure, heart rate, cardiac output and the function of cells that line cardiac blood vessels, AFP reported.

Scientists believe their findings may help doctors assess the effectiveness of drugs based on the time that the emergency condition has occured.
