FAQ

It is very common, and it is important to say so clearly.

Research consistently shows that many cardiac arrest survivors live with lasting effects — whether physical, cognitive or psychological — even when their clinical results look reassuring. Feeling that something has changed, that you tire more easily, worry more, or simply cannot quite get back to who you were before, is a recognised part of survivorship. It does not mean something has been missed medically. It means recovery is complex.

Some of the effects of cardiac arrest are visible — a scar, a device, a medication. Others are invisible. Cognitive changes such as slower processing, difficulties with memory or concentration, and fatigue that does not match how you look from the outside are all commonly reported. So is a persistent sense of anxiety, hypervigilance about your own body, or a changed relationship with the future.

These experiences are not a sign of weakness or failure to recover. They are normal responses to an event in which your heart stopped.

If you are not feeling back to normal, it is worth raising this with your GP or cardiac team rather than waiting to see if it resolves. You deserve support that reflects the full complexity of what you have been through, not just a reassuring scan result.

Yes, based on current research and international guidelines, they should.

Mental health screening — including assessment for anxiety and depression — is recommended as part of post-cardiac arrest follow-up care by the National Institute for Health and Care Excellence (NICE) and the European Resuscitation Council. Psychological distress is common after cardiac arrest, affecting an estimated 15 to 30% of survivors, and can be just as disabling as physical limitations.

In practice, many follow-up appointments focus primarily or exclusively on cardiac function — the echocardiogram, the device check, the heart rhythm. While these are important, they tell your clinical team very little about how you are managing your anxiety, your sleep, your ability to return to work, or your fear of a recurrence.

If your appointments have not included a conversation about your mental health or psychological wellbeing, it is worth raising this yourself. You might say: “I’ve been struggling with anxiety since the arrest” or “I don’t feel like myself — is there support available?” Your GP, cardiologist or cardiac rehabilitation team can make referrals to psychological support services.

You do not have to wait until things reach crisis point. Raising concerns early leads to better outcomes.

The figure is higher than many people expect, particularly given that younger survivors tend to have fewer physical problems and are often considered to be doing well. But surviving a cardiac arrest at a young age can be deeply distressing in ways that a physical assessment alone does not capture.

There is the shock of the event itself. The visceral knowledge that your heart stopped. The disruption to work, family life and a future that had seemed secure. The ongoing uncertainty about whether it could happen again. For those in their twenties, thirties or forties — perhaps with young children, a demanding job, and decades of plans — the psychological toll can be severe and long-lasting.

Research has consistently found that anxiety, depression and PTSD are common after cardiac arrest, and that younger survivors are disproportionately affected psychologically. A major Danish study found anxiety levels of nearly 30% in survivors under 35, compared to around 13.5% in those over 75.

Anxiety is a natural response to a traumatic event. The difficulty is that it can go undetected if follow-up appointments are focused almost entirely on physical recovery. If you are experiencing persistent worry, fear or panic since your cardiac arrest, it is worth raising this directly with your GP or cardiac team. You do not have to wait to be asked.

After a cardiac arrest, both the body and mind go through a significant recovery process. The difference age makes comes down to what each group is most vulnerable to at that stage of life.

For older survivors, a cardiac arrest can accelerate or worsen physical decline that was already beginning. Mobility, self-care and the ability to carry out daily activities can all become noticeably harder. These changes may seem gradual, and it is not always easy to connect them clearly to the arrest, particularly when overall clinical scores look reassuring.

For younger survivors, the psychological impact tends to dominate. Being young and otherwise healthy, then experiencing a sudden, life-threatening event, can trigger intense anxiety and a lasting fear that it will happen again. There is also the disruption to work, family life and long-term plans that older survivors may be less reliant on in the same way.

A major Danish study of 2,552 survivors found that older survivors (particularly those over 75) reported significantly higher rates of physical difficulty, while those under 35 showed anxiety levels of nearly 30%. These are genuinely different experiences of the same event, shaped by age and life stage — and they call for different types of support.

Several routes to psychological support are available after cardiac arrest.

Your GP is the first point of contact. They can assess your mental health, prescribe medication if appropriate, and refer you to talking therapy. In England, NHS Talking Therapies (formerly IAPT) provides free CBT, counselling, and other therapies, usually without a long wait. You can also self-refer to NHS Talking Therapies online without going through your GP first.

Your cardiac team may also be able to refer you to a clinical psychologist or cardiac rehabilitation programme. Cardiac rehabilitation often includes a psychological component alongside exercise and education, and is recommended for cardiac arrest survivors.

For more specialist support — for example, if you have complex PTSD, severe depression, or significant cognitive impairment — your GP can refer you to community mental health services or a neuropsychologist.

Peer support — connecting with other survivors and co-survivors who understand the experience from the inside — is highly valued by many people after cardiac arrest. Sudden Cardiac Arrest UK can connect you with peer support resources and a community of people who have been through similar experiences.

For co-survivors, the same routes apply. You do not need to have been the patient to deserve psychological support.

Category: Cardiac Arrest

Yes. PTSD (post-traumatic stress disorder) is common after cardiac arrest — both in survivors and in co-survivors who witnessed the event or performed CPR.

Survivors may develop PTSD even without remembering the arrest itself. PTSD can develop in relation to the ICU experience, the fear of further cardiac events, distressing memories of what happened in hospital, or the experience of receiving ICD shocks. Symptoms include flashbacks or intrusive thoughts, nightmares, hypervigilance, avoidance of reminders of the event, emotional numbing, irritability, and difficulty sleeping.

Co-survivors — partners, family members, and friends — are also at significant risk of PTSD following a cardiac arrest. The experience of witnessing a collapse, performing CPR, or facing the possibility of losing someone is profoundly traumatic.

PTSD is a recognised medical condition and is treatable. The most effective treatments include trauma-focused CBT (cognitive behavioural therapy) and EMDR (Eye Movement Desensitisation and Reprocessing). Both are available through NHS Talking Therapies — speak to your GP for a referral. You do not have to be formally diagnosed with PTSD to access these services; if you are experiencing significant distress, that is reason enough to seek support.

If you are in crisis or feel unable to cope, please contact your GP, call 111, or contact the Samaritans on 116 123.

Yes — even if you were not the one who performed CPR, witnessing a cardiac arrest is a profoundly shocking experience. Seeing someone you love collapse, not knowing whether they would survive, spending days or weeks at a hospital bedside, and then navigating their recovery at home can all leave lasting psychological effects.

What you experienced meets the criteria for a potentially traumatic event. It is entirely normal to have intrusive thoughts, disturbing dreams, difficulty concentrating, heightened anxiety, fear of it happening again, or periods of low mood — even weeks or months after the event. You may also find yourself feeling emotionally numb or detached, or swinging between feeling fine and feeling overwhelmed.

These are not signs of weakness. They are signs that something very frightening happened to you, and your mind and body are still processing it. Many co-survivors find that symptoms reduce naturally over time with the support of people around them. Others find that symptoms persist or worsen, in which case professional support is recommended.

Talk to your GP about what you are experiencing. You can also contact Sudden Cardiac Arrest UK to connect with others who understand what you have been through.

Yes, and this is particularly true when CPR is performed on a loved one — one of the most distressing experiences a person can face. You were trying to keep someone alive, possibly not knowing whether your efforts were working. That is deeply traumatic, regardless of the outcome.

People who have performed CPR commonly report intrusive thoughts and flashbacks replaying the moment of collapse or the resuscitation itself, guilt about whether they started quickly enough or did it correctly, hypervigilance about the survivor’s health, fear of being left alone with them, and difficulty sleeping.

It is important to know that guilt about CPR performance is extremely common and almost never warranted. Even trained paramedics do not perform CPR perfectly under stress. Imperfect CPR is far better than no CPR, and the fact that you acted almost certainly made a difference.

If you are struggling with distressing thoughts, difficulty sleeping, anxiety, or low mood, please talk to your GP. Effective treatments are available, including trauma-focused CBT and EMDR. You can also contact SCA UK for peer support from others who have been through similar experiences.

Category: Psychological Support

A co-survivor is a family member, partner, friend, or colleague who was present at a cardiac arrest or closely affected by it. The term recognises that a cardiac arrest is a traumatic event not just for the person who experienced it, but for everyone around them — particularly those who witnessed the collapse, performed CPR, called 999, or waited at the hospital not knowing whether their loved one would survive.

Co-survivors are sometimes called secondary survivors. Their psychological needs are distinct from those of the survivor themselves, but equally real and equally valid. Research consistently shows that co-survivors experience high rates of anxiety, depression, post-traumatic stress disorder (PTSD), and fear of recurrence — often persisting long after the survivor has been discharged home and is visibly recovering.

Despite this, co-survivors frequently report that their needs go unrecognised by healthcare services, which tend to focus on the patient. If you are a co-survivor, your experience matters. Support is available — through peer support networks, psychological services, and organisations such as Sudden Cardiac Arrest UK.

Category: Co-survivors

Some survivors of cardiac arrest experience medical problems, including impaired consciousness and cognitive deficits. Functional recovery continues over the first six to 12 months after out-of-hospital cardiac arrest in adults. It is common for survivors to have memory loss and to experience depression and anxiety for some time after their event.

It is very common to feel anxious before getting a heart device. Concern about the procedure itself, about what having an ICD means for your life, and about the underlying condition that led to the recommendation are all understandable responses.

The most effective way to manage anxiety around the procedure is to get clear, reliable information — which is what this site is here to provide. Knowing what to expect before, during, and after implantation, and understanding how your ICD works and what it will and will not prevent you from doing, can significantly reduce fear of the unknown.

If your anxiety is significant or persistent, do speak to your GP or cardiac team. Psychological support is available, and you do not need to manage this alone. Peer support — talking to others who have been through the same procedure — is also highly valued by many people. Contact SCAUK to find out more.
