PTSD Hinders Sleep after Heart Attack, Increases Risk

PTSD Hinders Sleep after Heart Attack, Increases Risk New research suggests the development of post-traumatic stress disorder after a heart attack may explain why sleep is often impaired in some survivors.

Recent data from Columbia University Medical Center researchers have shown that symptoms of PTSD after a heart attack are relatively common.

Prior research found that one in eight heart attack survivors suffer PTSD and that survivors with PTSD have a doubled risk of having another cardiac event or of dying within one to three years, compared with survivors without PTSD.

A new study reviews the association of PTSD and sleep in nearly 200 patients who had experienced a heart attack within the previous month.

The study, published in the current issue of Annals of Behavioral Medicine, found that PTSD following a heart attack is associated with poor sleep.

Jonathan A. Shaffer, Ph.D., and colleagues at Columbia’s Center for Behavioral Cardiovascular Health discovered that the more heart attack-induced PTSD symptoms patients reported, the worse their overall self-reported sleep was in the month following their heart attack.

Greater PTSD symptoms following a heart attack were associated with worse sleep quality, shorter sleep duration, more sleep disturbances, use of sleeping medications, and daytime dysfunction due to poor sleep the night before.

The data also showed that people with poor sleep following a heart attack were more likely to be female and to have higher body mass index and more symptoms of depression; they were less likely to be Hispanic.

Shaffer and colleagues hypothesize that the strong association between heart attack-induced PTSD and sleep may be due to the fact that disturbed sleep is a standard characteristic of PTSD. Results of recent treatment studies for PTSD and sleep disturbance suggest that the two conditions should be viewed as occurring together, rather than one being merely a symptom of the other.

In addition, dysregulation of the autonomic nervous system (the part of the nervous system responsible for regulating involuntary bodily functions, such as breathing, heartbeat, and digestive processes), which is associated with both PTSD and disrupted sleep, may represent a common mechanism underlying their association.

Study authors say that further research is needed to better understand the associations of PTSD due to heart attack, poor sleep and risk for future heart attacks.
