People who experience post-traumatic stress disorder (PTSD) after surviving cardiac arrest, may be at a significantly increased risk of a major cardiovascular event or death for up to one year following the arrest, compared with people who do not develop PTSD. 

 

Now, a study led by Sachin Agarwal involving 114 patients who had been resuscitated following cardiac arrest between 2015 and 2017 has shown that those who developed PTSD were at a three-fold greater risk of experiencing a major cardiovascular event or death from any cause, compared with those who did not develop PTSD.
