Cardiac anxiety is a specific pattern of health anxiety that develops after a cardiac event such as a heart attack or cardiac arrest. Survivors become hypervigilant about their heart, monitoring every beat, twinge, or sensation for signs that something is wrong. Normal physical sensations, such as a slightly raised pulse after climbing stairs, can trigger significant fear.
Cardiac anxiety is closely related to post-traumatic stress disorder (PTSD). Research suggests that between 20 and 30 per cent of cardiac arrest survivors experience clinically significant levels of anxiety or PTSD in the months and years that follow. Many more experience subclinical levels that still significantly affect their quality of life.
If you think you may be experiencing cardiac anxiety, speaking to your GP is a good starting point. Cognitive behavioural therapy (CBT) has a good evidence base for this type of anxiety. The British Heart Foundation also offers information on psychological support after a cardiac event.
