In an investigation of more than 200,000 people, researchers found the spouses of those who experience a sudden heart attack have an increased risk of depression, anxiety and suicide afterward. That's even if their partner survives, according to the European Heart Journal.
They also tend to suffer more psychologically than the partners of people who have other serious medical conditions.
A heart attack can impact the whole family.
Researchers say this study emphasizes the importance of caring for the partners of heart attack sufferers.
