Yes, it could still be possible to secure critical illness cover (CIC) after a heart attack, depending on your personal circumstance and the severity of your condition.
Critical illness cover will pay out a cash lump sum if you’re diagnosed with a critical, but non-life-threatening illness, for example:
Cancer Liver or kidney failure Multiple Sclerosis Dementia Blindness
It can also cover heart conditions, but if a heart condition is pre-existing, then insurers may exclude this condition, and any related conditions, from your cover.
However, critical illness cover can still help protect you against the financial impact of other serious conditions listed in your policy.
