The researchers say that suggests grief could be a risk factor for cardiac events.
The study, published in the journal Psychosomatic Medicine, demonstrates an association between grief severity and elevated systolic blood pressure response.
The idea of “dying of a broken heart,” which can happen following the loss of a loved one, was the motivation for the research, says senior author Mary-Frances O’Connor, an associate professor of psychology at the University of Arizona who specializes in grief.
Increased risk of mortality after the death of a loved one has long been documented in epidemiological studies. For the new study, which included 59 participants that had lost a close loved one in the past year, O’Connor and colleagues looked at blood pressure as a possible contributing factor.
“We were looking for a way to test the cardiovascular effects of grief during that vulnerable time in the first year after the loss,” says lead author Roman Palitsky, who was a doctoral student at the University of Arizona when the study was conducted and is now the director of research projects in spiritual health at Emory University Woodruff Health Sciences Center.
The researchers interviewed study participants and asked them to focus on feelings of separation and attachment through a process researchers call “grief recall.”
The researchers talked to each participant for 10 minutes and asked them to share a moment when they felt very alone after the death of their loved one. The researchers then measured the study participants’ blood pressure.
“When you go to a cardiologist, they don’t just measure your blood pressure. They also sometimes do a stress test, like a treadmill, and measure your blood pressure. This is sort of like an emotional stress test,” O’Connor says.
After grief recall, participants’ systolic blood pressure—which is the pressure that the heart exerts on the arteries while beating—increased. From the baseline level, systolic blood pressure climbed by an average of 21.1 millimeters of mercury—the unit used to measure blood pressure. That is approximately as much of an increase as would be expected during moderate exercise.
Among the 59 participants, those who showed the highest level of grief symptoms experienced the greatest increase in blood pressure during the grief recall.
“This means that it isn’t just the death of a loved one that impacts the heart, but our emotional response to loss that is affecting our heart,” O’Connor says.
The study’s findings are helpful for clinicians, as they show that people who are experiencing bereavement are at higher risk for hypertension and other heart-related problems, O’Connor says.
“It’s important for psychologists and therapists to encourage grieving clients to get their regular medical checkups. Often, when we’ve been caring for a loved one who’s dying, we neglect our own health care,” she says.
