Although heart health and mental health are often viewed as distinct, they are very much related. The tight connection between the mind and heart can be good news – if you take steps to protect one, you may be protecting the other as well.
A two-way relationship
People with depression have an increased risk for developing heart disease. The reverse is also true. People with heart disease – such as those who have had a heart attack or developed heart failure – have an increased risk for developing depression.
One reason the two conditions often occur together is because they have an array of related risk factors. For example, having heart disease may cause someone to limit their activities, which may increase their risk of depression. Meanwhile, people who are depressed may be more likely to adopt unhealthy habits such as not exercising enough, drinking too much alcohol, smoking and eating poorly – all of which increase one’s risk for heart disease.
Depression impacts the heart
Although it’s sometimes considered “mental” and separate from the body, depression has a physical basis and a host of physical effects, many of which relate to heart function. These effects include:
- Inflammation that can damage the lining of blood vessels, paving the way for atherosclerosis (hardening of the arteries)
- Increased tendency of blood to clot, which can accelerate atherosclerosis
- Nervous system changes that alter heart rate
These types of changes lead to a higher risk of heart attack and sudden cardiac arrest in patients with depression.
Meanwhile, experiencing a serious manifestation of heart disease, such as a heart attack, increases depression risk. Up to one in three people who have had a heart attack will have symptoms of depression.
The heart can influence depression
A heart attack survivor often has obvious reasons for feeling depression symptoms along with the physical responses. Such a profound event can change your perspective on life and cause unease about what comes next. Someone who has had a heart attack might look back with regret at behaviors he/she believe increased their risk. They might also see themselves differently and experience lost confidence or increased doubts about their ability to succeed at work or in personal relationships.
Although these feelings are natural following a life-threatening health event, they can snowball into something bigger – a mental health struggle that affects your ability to function. When that happens, getting the right intervention is crucial because depression cannot only be dangerous in its own right, it may also interfere with recovery from the heart attack.
In addition to starting a cardiac rehabilitation program to help rebuild physical stamina, counseling and medication support can help ease the symptoms of depression and get you on the path to recovery for mind and heart.
Knowing when feelings of worry and loss cross over into depression can be tough, but one key is to assess for zest: Do you feel the same enthusiasm about things that you enjoyed before? If not, an assessment for depression might be in order.
The stress effect
Depression isn’t the only mental health condition tied to heart disease. Emotional distress can also raise the odds of disease in the arteries that feed the heart. Although conventional wisdom has always linked stress and heart attacks, research more recently confirms that psychological stress increases risk for a heart attack or stroke. In fact, the greater the stress, the greater the risk.
What you can do
For people who already have heart disease and depression or anxiety, mental health treatment may help reduce the risk for heart-related death. In fact, many cardiac rehab programs include a mental health component.
Generally, patients tend to benefit from some combination of medicines that boost mood along with counseling from a therapist who can help change thought patterns, address unhealthy behaviors and suggest ways to relax.
Prevention strategies
Although you can’t control every factor that contributes to the risk for heart disease or depression, you can influence many of them. A healthy diet can help keep mind and heart in shape, as can regular exercise and avoiding smoking or drinking too much alcohol.
Because stress can contribute to heart disease and stroke risk, learning ways to relieve mental burdens can also be helpful.
There are many ways to relieve stress, and your choice will come down to what genuinely works for you. In addition to the recommended lifestyle adjustments that boost mind and heart health alike, some helpful stress-busters include deep-breathing exercises, meditation or mindfulness practices and working with a counselor to remove causes of stress where possible.
