New research shows that even mild depression may make a person more vulnerable to a heart attack. Canadian scientists studied more than 200 men and women who suffered heart attacks. The found that those who had the most symptoms of depression, such as feelings of sadness or hopelessness, were the most likely to die of a heart attack within 18 months of their first heart attack. 21 patients died of heart attacks during the 18 months of the study. 19 of them met diagnostic criteria for depression.
Scientists say the study reinforces current thinking about depression and heart attacks.
Stress, depression or some other type of emotional distress may unbalance the part of the nervous system that controls blood pressure and heart rate. While researchers say there's an obvious need for more research on the link between depression and heart attack, it's clear that physicians need to pay attention to their patient's mental well-being. The researchers said it might be a good idea to test heart attack survivors for depression. They also want to know if treatment for depression after a heart attack can increase the heart attack patient's chance of survival. In the meantime, researchers at UT Southwestern Medical Center at Dallas say there are things you can do to reduce your risk of heart attack.
