Depression is common among people who had heart attacks. Those who are depressed seem to be sicker and have more physical symptoms such as chest pain. Yale University and local New Haven study participants contributed to two studies examining the relationship between heart attacks and depression.
To improve care for those patients who suffer from heart attacks and depression, researchers wanted to know who was most at risk for depression and if the timing of the depression resulted in poorer health 6 months after a heart attack. Women and men who had heart attacks completed a survey that measured depression during hospitalization and 1 month later. Results show:
- Women 60 years of age or younger had the hightest rates of depression after heart attacks.
- Having depression during hospitalization or 1 month later is
an important risk factor for poor health outcomes:
- hospitalized again
- more chest pain
- physical limitations lower quality of life
Heart attack: The coronary arteries fuel the heart muscles with their blood supply. When these arteries cannot supply enough blood to the heart muscle, a heart attack occurs. This causes permanent damage to the heart muscle, and parts of the heart muscle die.
Depression: Depression is a common medical condition.
- Emotional symptoms: sadness, loss of interest in things that usually make you happy, feelings of guilt or worthlessness, and trouble making decisions.
- Physical symptoms: tiredness, aches and pains, eating and sleeping too much or too little.
- Depression is more common in younger women who have had heart attacks.
- Poor health after heart attacks is more common when the patient is also depressed.
