Grief over losing loved one linked to higher heart attack risks

Posted: 09 Jan 2012 06:20 PM PST

Heart attack risks are extremely high for the bereaved in the days and weeks after losing a loved one. The first day after a loved one died, heart attack risk was 21 times higher than normal, which declined progressively over the first month.

Posted: 09 Jan 2012 06:18 PM PST

Dispatchers should help 9-1-1 callers identify cardiac arrest victims and coach callers to provide immediate CPR. If more dispatchers followed these processes, thousands of lives could be saved every year. Communities should regularly evaluate 9-1-1 emergency dispatchers' performance and the overall emergency response system, according to a new American Heart Association statement.
