Managing Your Emotions Can Save Your Heart
We often think of the heart and brain as being completely separate from each other. After all, your heart and brain are located in different regions of your body, and cardiology and neurology are separate disciplines. Yet these organs are intimately connected, and when your emotions adversely affect your brain, your heart is affected as well.
The negative impact of emotions when your heart is already vulnerable
There are two kinds of stress that impact your brain. Helpful stress (also known as eustress) can actually assist you with getting things done by helping you focus your attention. Unhelpful stress (distress), on the other hand, can be so severe that it can lead to fatigue and heart disease.
If you have coronary artery disease (CAD), your heart may be deprived of oxygen. This deprivation, called myocardial ischemia, can occur in as many as 30% to 50% of all patients with CAD. It can be further exacerbated by emotional stress. In fact, if you have any type of heart disease, any strong emotion such as anger may also cause severe and fatal irregular heart rhythms. Expressions like “died from fright” and “worried to death” are not just hyperbole — they are physiologic possibilities. Furthermore, when patients with newly diagnosed heart disease become depressed, that depression increases the risk that a harmful heart-related event will occur within that year.
The negative impact of emotions when you have no heart disease
Of course, stress can have a big effect on your heart even if you don’t have heart disease. Here’s just one example: In 1997, cardiologist Lauri Toivonen and colleagues conducted a study of EKG changes in healthy physicians before and during the first 30 seconds of an emergency call. They saw changes that indicated oxygen deprivation and abnormal heart rhythms.
More recent studies have also observed these changes in the setting of with stress, anxiety, and depression — all of which are, of course, brain-based conditions. Even in people with no prior heart disease, major depression doubles the risk of dying from heart-related causes.
Cardiac psychology: Tending to your emotions for your heart’s sake
It is important to control your worry and stress, not just because you will worry less and feel better, but because less worry means less stress for your heart. This applies to the entire range of stressors, from a small episode of acute panic to a larger context such as living through a natural disaster. For all the reasons outlined above, a new emotion-based approach to heart health, called cardiac psychology, is receiving increasing interest.
You really can change your brain and get a healthier heart in the process. Here are some ways to get started:
- Seek professional help. Don’t ignore stress, anxiety, depression, excessive worry, or bouts of anger that overwhelm your life. Seek professional help. If you meet criteria for a diagnosis, treatment can help reduce symptoms, thereby protecting your brain and your heart.
