The psychological impact of surviving a cardiac arrest is significant and often underestimated — by survivors themselves, by their families, and sometimes by the clinical teams caring for them. Anxiety, depression, post-traumatic stress, and emotional changes are all common responses to an experience that is, by definition, life-threatening and profoundly disorienting.
This leaflet provides information and support on mental health well-being after cardiac arrest. It is intended for survivors and their families, and for the healthcare professionals who support them.
Why mental health is affected
A cardiac arrest is a traumatic event. The brain experiences it as a threat to survival, and the psychological system responds accordingly — often with heightened anxiety, hypervigilance, intrusive thoughts, and a changed relationship with the body and with mortality. These responses are normal. They are not a sign of weakness or mental illness, though they can develop into treatable conditions if not addressed.
Co-survivors — partners, family members, and close friends — are also commonly affected. Witnessing a cardiac arrest is traumatic, and the ongoing anxiety about the future can be substantial.
Getting support
Effective support is available. Talking therapies including cognitive behavioural therapy (CBT) and EMDR have good evidence in cardiac arrest survivor populations. Peer support — connecting with others who have lived through similar experiences — is also highly valued by many survivors and co-survivors.
SCA UK offers a community where mental health experiences can be shared openly and without judgement. If you are struggling, please reach out. You can also find more information on our After-Effects section and our Get Support pages.
