Losing a loved one is heartbreaking in any case. Little did we know however, is that bereavement can lead to serious cardiovascular issues.
Scientists looked at GP data on thousands of individuals aged 60 and over in the UK, some of whom had recently lost partners.
They found that 16 per 1,000 patients suffered a heart attack or stroke within 30 days of a partner's death - double the rate for those whose loved ones remained alive.
The heightened risk among bereaved men and women starts to fall after 30 days, according to findings published in the journal JAMA Internal Medicine.

Lead researcher Dr Sunil Shah, from St George's, University of London, said: "We often use the term a 'broken heart' to signify the pain of losing a loved one and our study shows that bereavement can have a direct effect on the health of the heart."
He added: "There is evidence, from other studies, that bereavement and grief lead to a range of adverse responses including changes in blood clotting, blood pressure, stress hormone levels and heart rate control.
"All these will contribute to an increased risk of events such as heart attacks and stroke after loss of a partner.
"In addition, we have found, in another study, that in the first few months after bereavement, individuals may not consistently take their regular preventive medication, such as cholesterol-lowering drugs or aspirin.
"Sudden short-term interruption of such regular medication may also contribute to the increased risk of cardiovascular events.
"We think it is important that doctors, friends and family are aware of this increase 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."
Co-author Dr Iain Carey, also from St George's, University of London, said: "We have seen a marked increase in heart attack or stroke risk in the month after a person's partner dies which seems likely to be the result of adverse physiological responses associated with acute grief.
"A better understanding of psychological and social factors associated with acute cardiovascular events may provide opportunities for prevention and improved clinical care."Suggest a correction
