Lack of a Close Confidant Increases the Risk for Cardiac Events After a Heart Attack
Approximately one of every twenty Americans experiences
Studies have also shown that a lack of social support after a heat attack is associated with a patient’s poor compliance to a treatment plan and poor health outcomes. To address these issues, many hospitals now have programs specifically designed to identify depression and provide social support for their cardiac patients. But, what happens if these risks are present before a heart attack occurs? In a study published in the May 2004 issue of Heart , researchers considered how depression and lack of social support before a heart attack might influence how patients fair after a heart attack.
About the Study
The study included 583 adults who were admitted to a hospital with a diagnosed heart attack. Three to four days after the heart attack, patients were questioned on several different areas, including:
- Social support: defined in terms of a close confidant (someone the patient had regular contact with—at least once a month—and with whom he or she could share sensitive personal information and gain support)
- Anxiety and depression: assessed using the hospital anxiety and depression scale (HADS)
- Age, sex, marital status, and years of education
- Smoking and use of alcohol and illegal drugs
- Personal and family histories of cardiovascular disease, and personal psychiatric history
- Details of separation from parents during childhood
At the end of 12 months, nine study participants died from non-cardiac causes; these nine were excluded from the study analysis. Of the 574 study participants included in the final analysis, 118 experienced a definitive cardiac event; 29 of whom died from cardiac causes.
Although there was a high incidence of depression in the sample, the researchers found that the participants who experienced a cardiac event were not more likely to have depression before the heart attack. However, they were less likely to have a close confidant. In fact, the participants with a close confidant had only half the risk of a further cardiac event than those who did not. Additionally, those without a close confidant were more likely to have had two or more heart attacks when they first presented prior to recruitment into the study.
Other characteristics that increased a person’s risk of an additional cardiac event after a heart attack were female sex, a history of
Although the study’s authors could not definitely say why having a consistent source of social support appeared to confer a protective effect, they did find that participants without such support were more likely to engage in behaviors that are associated with health risk, including:
- Drinking alcohol four or more times a week
- Consuming more than six drinks in a single session at least once a week
- Using illegal drugs
- Smoking tobacco
How Does This Affect You?
The study’s authors stress that, although they did not find a relationship between depression prior to a heart attack and health outcomes afterward, treating depression as a means to lower the risk of
Likewise, this study shows that the importance of social support should not be overlooked. Being socially connected has many health benefits. According to this and other studies, confiding in other people can be just as important as eating well and exercising when it comes to the health of your heart. If you are feeling alone or lack someone from whom you can gain support, explore what opportunities your community can provide for meeting people.
