33.1%correct

Monday and Tuesday mornings after the switch to daylight saving time, when clocks move ahead one hour in spring, may see a 10 percent increase in the incidence of heart attacks.
The opposite trend occurs in the fall when clocks switch back to standard time. According to the study, the Monday morning after the switch is the most dangerous time, with heart attack risks peaking when people are getting up earlier to go to work. Source -ScienceDaily.com
