Overview, Causes, & Risk Factors

Depression is a medical condition that leads to intense feelings of sadness or despair. These feelings don’t go away on their own.

What is going on in the body?

Several factors can make a person feel depressed after a heart attack. The stress of being in the hospital, the fear of another heart attack, and the reality of having to make lifestyle changes can all contribute. If the person had to have bypass surgery, he or she will have to endure a long recovery period. This could include being out of work for up to six weeks.

What are the causes and risks of the condition?

There are many theories about what causes depression. Depression may be caused by any of the following:

    The two most common ways of treating depression are with antidepressant medications and psychotherapy. Often a combination is used. Occasionally a person must be hospitalized for intense treatment or for his or her own safety.

    Antidepressant medications are effective in the following ways.

  • They lower the risk of suicide.
  • They make the person feel better.

    • The following types of medications are used to treat depression:

  • tricyclic antidepressants, or TCAs, including amitriptyline HCl and desipramine HCl
  • tetracyclic antidepressants, such as maprotiline HCl and mirtazapine
  • monoamine oxidase inhibitors, which are also called MAOIs, such as phenelzine sulfate and tranylcypromine sulfate
  • selective serotonin reuptake inhibitors, or SSRIs, including paroxetine HCl and fluoxetine HCl
  • other antidepressants, such as nefazodone and venlafaxine

    • Psychotherapy can help people do the following:

  • cope better with having depression
  • feel less alone
  • improve relations with family, friends, and coworkers
  • learn about depression and how it affects them
  • learn to recognize and avoid situations that can bring on a depressive episode
  • learn to view the world and others more positively and more realistically
  • positively address problems that they may be facing
  • stop episodes of depression early by recognizing warning signs and symptoms
    • What are the side effects of the treatments?

    Antidepressants may cause mild and usually temporary side effects in some people. Following are the most common side effects:

  • agitation
  • constipation
  • dizziness
  • drowsiness
  • dry mouth

    • What happens after treatment for the condition?

    An individual can help prevent relapses by living a healthy lifestyle. Following are some important parts of a healthy lifestyle:
