Spouses of Heart Attack Patients More Prone to Depression, Anxiety and Suicide
Spouses of people who suffer a sudden heart attack have an increased risk of depression, anxiety, or suicide, even if their partner survives, according to new research.
The study, published in the European Heart Journal, also found that men were more susceptible to depression and suicide after their wife’s survival or death from an acute myocardial infarction (AMI).
Using data from Danish registries, including the National Civil Status Registry that shows whether people are married, researchers in the United States and Denmark compared 16,506 spouses of people who died from an AMI between 1997 and 2008 with 49,518 spouses of people who died from causes unrelated to AMI.
They also matched 44,566 spouses of patients who suffered a non-fatal AMI with 131,563 spouses of people admitted to the hospital for a non-fatal condition unrelated to AMI.
They looked at the use of antidepressants and benzodiazepines (used for treating anxiety) before and up to a year after the event, records of contact with the health system for depression, and suicide.
“We found that more than three times the number of people whose spouses died from an AMI were using antidepressants in the year after the event compared with the year before.
In addition, nearly 50 times as many spouses used a benzodiazepine after the event compared to before,” said Emil Fosbøl, M.D., Ph.D., the first author of the study.
“Those whose spouse survived an AMI had a 17 percent higher use of antidepressants after the event, whereas spouses of patients surviving some other, non-AMI related condition had an unchanged use of antidepressants after the event compared to before.”
The study also found that, while rates were low, people who lost a spouse to a fatal AMI or whose spouse survived an AMI committed suicide more often than those with spouses who died from, or survived, a non-AMI-related event, according to Fosbøl, who was a cardiology research fellow at Duke University Medical Center in North Carolina at the time of the research.
“We also found that men were more likely to suffer depression and commit suicide after an event than women,” he said.
The researchers speculate that it is the sudden and unexpected nature of an AMI that causes the more extreme impact on the spouse.
“If your partner dies suddenly from a heart attack, you have no time to prepare psychologically for the death, whereas if someone is ill with, for example, cancer, there is more time to grow used to the idea,” said Fosbøl.
“The larger psychological impact of a sudden loss is similar to post-traumatic stress disorder.”
The findings have public health implications as more than 7 million people worldwide experience an AMI a year, with around 16 percent of them dying from it within a month, according to the scientist.
“This could mean that around 11,000 people would be likely to start antidepressants after a spouse’s non-fatal AMI, and 35,000 after their spouse died from an AMI,” he said. “Moreover, although suicide rates were low, we could expect approximately 1,400 people to take their own life in the year following a spouse’s death from a heart attack.
“This is a major public health issue for which there seems to be very little awareness among doctors and policy makers,” he continued. “I think the most important finding of this study is that the system needs to consider the care needs for spouses too, not only when a patient dies from an AMI, but also when the patient is ‘just’ admitted to hospital with an AMI and survives.
“Previously, we did not have any data on those patients’ spouses where the patient survived the event.”
The researchers note it appears there are no mechanisms in place to identify spouses at risk and to institute preventive strategies such as screening for depression and grief counseling.
“I think it would be worth conducting a study of a targeted intervention to prevent depression for the spouse,” Fosbøl said. “I believe that treatment of an acute event also should include screening the spouse for possible psychological effects and a plan should be in place for how to take care of this, if indeed the spouse is severely affected.”
