Mental health disorders can be short- or long-term and can interfere with a person's mood, behavior, thinking, and ability to relate to others. Various studies have shown the impact of trauma, depression, anxiety, and stress on the body, including stress on the heart.123
Some of the most commonly studied mental health disorders associated with heart disease or related risk factors include the following:
Mood Disorders: People living with mood disorders, such as major depression or bipolar disorder, find that their mood affects both psychological and mental well-being nearly every day for most of the day.
Anxiety Disorders: People respond to certain objects or situations with fear, dread, or terror. Anxiety disorders include generalized anxiety, social anxiety, panic disorders, and phobias.
Post-Traumatic Stress Disorder (PTSD): People can experience PTSD after undergoing a traumatic life experience, such as war, natural disaster, or any other serious incident.
Chronic Stress: People are in a state of uncomfortable emotional stress—accompanied by predictable biochemical, physiological, and behavioral changes—that is constant and persists over an extended period of time.
There may be other behavioral health disorders, such as substance use disorders, that are connected to heart disease.
A large and growing body of research shows that mental health is associated with risk factors for heart disease before a diagnosis of a mental health disorder and during treatment. These effects can arise both directly, through biological pathways, and indirectly, through risky health behaviors.4
People experiencing depression, anxiety, stress, and even PTSD over a long period of time may experience certain physiologic effects on the body, such as increased cardiac reactivity (e.g., increased heart rate and blood pressure), reduced blood flow to the heart, and heightened levels of cortisol. Over time, these physiologic effects can lead to calcium buildup in the arteries, metabolic disease, and heart disease.15678910
Evidence shows that mental health disorders—such as depression, anxiety, and PTSD—can develop after cardiac events, including heart failure, stroke, and heart attack.4111213141516171819 These disorders can be brought on after an acute heart disease event from factors including pain, fear of death or disability, and financial problems associated with the event.415
Some literature notes the impact of medicines used to treat mental health disorders on cardiometabolic disease risk. The use of some antipsychotic medications has been associated with obesity, insulin resistance, diabetes, heart attacks, atrial fibrillation, stroke, and death.20
Mental health disorders such as anxiety and depression may increase the chance of adopting behaviors such as smoking, inactive lifestyle, or failure to take prescribed medications.4 This is because people experiencing a mental health disorder may have fewer healthy coping strategies for stressful situations, making it difficult for them to make healthy lifestyle choices to reduce their risk for heart disease.4
Specific populations, such as the following, show higher rates of heart disease as a result of pre-existing mental health disorders:
Veterans. Studies found that veterans are at a higher risk for heart disease, mainly due to PTSD as a result of combat.2122232425
Women. Studies exclusively focused on women found that PTSD and depression may have damaging effects on physical health, particularly with increased risk for coronary heart disease (CHD)–related morbidity and mortality.2627
Couples with someone who has PTSD. Comparative studies found that couples where one or both partners had PTSD experienced more severe conflict, greater anger, and increased cardiovascular reactivity to conflict discussions than couples where neither partner had PTSD. Anger and physiological stress responses to couple discord might contribute to CHD and heart disease risk within these relationships.2829
Racial and ethnic minorities. Lastly, studies focused on racial or ethnic minority groups found that depression, stress, and anxiety due to disparities in social determinants of health,30 adverse childhood experiences,31 and racism/discrimination323334 could place certain subpopulations at a higher risk for hypertension,31323435 cardiovascular reactivity,34 heart disease,3033 and poor heart health outcomes.36
Addressing mental health disorders early by providing access to appropriate services and support to increase healthy behaviors (e.g., increased physical activity, improved diet quality, and reduced smoking) can reduce someone's risk of experiencing a heart disease event.1214161827373839
Below are some actions that health care systems, health care professionals, individuals, and researchers can take to promote heart disease prevention and support mental health.
