The first month is crucial, but then the threat diminishes, researchers say

MONDAY, Feb. 24, 2014 (HealthDay News) -- It's often said that the loss of a spouse or partner leaves "a broken heart." That notion might have some scientific validity, with new evidence suggesting the risk for a heart attack or stroke goes up during the first few weeks of bereavement.
"Our study shows the likelihood of a heart attack or stroke doubles in the crucial 30-day period after a partner's death for those experiencing loss of a loved one," said study co-author Sunil Shah.
Bereavement has long been known as a risk factor for death. Prior work has suggested that grief has a direct negative impact on blood clotting risk, blood pressure, stress hormone levels and heart rate control, said Shah, a senior lecturer in public health at St. George's University of London in England.
But citing a lack of sufficient information on the specific impact of bereavement on heart disease, Shah and his colleagues examined thousands of heart health histories contained in a large British primary care database.
The team focused on information concerning nearly 30,500 British men and women between 60 and 89 years old, all of whom had lost a partner between 2005 and 2012. They also looked at the histories of about 83,600 similarly aged men and women who had not lost a partner in that time frame.
The researchers found that in the month following a partner's death, the incidence of fatal or non-fatal heart attack and stroke was roughly double among men and women in the bereavement group, compared with those in the non-bereavement group. The numbers were relatively small, however -- 50 heart attacks or strokes among the bereaved group, versus 67 for the non-bereaved group.
The finding held up whether looking at the combined risk for heart attack and stroke, or at individual risk for just one or the other, the researchers said.
"We think it is important that doctors, friends and family are aware of this increased risk of heart attacks and strokes so they can ensure care and support is as good as possible at a time of increased vulnerability before and after loss of a loved one," Shah added.
