One of every 8 patients who have a myocardial infarction or other acute coronary event develops clinical symptoms of posttraumatic stress disorder (PTSD) annually in the United States, according to recent research.
In a meta-analysis, researchers examined data from 24 studies that included 2383 patients with acute coronary events worldwide. The study also showed that developing PTSD doubles the risk of having another acute episode or dying within 1 to 3 years, compared with cardiac patients who didn't develop PTSD. Given that some 1.4 million patients are hospitalized annually with an acute coronary event, the investigators estimated that 12%, or 168 000 patients, will develop PTSD (Edmondson D et al. PLoS ONE. 2012;7:e38915).
