How underwriting usually handles it

• Health insurers normally exclude the heart and circulation where there is a diagnosed cardiac condition.
• Life underwriters may accept with a loading depending on the event, the treatment and how long ago it was.
• Critical illness cover after a cardiac event is often declined or heavily excluded.
• Income protection depends on the effect on your ability to do your own job.

Which underwriting basis you choose changes the answer more than the condition itself does. Our guide to moratorium versus full medical underwriting explains the two routes; in short, a moratorium asks nothing up front and decides later, while full underwriting decides now and puts the answer in writing.

What is commonly excluded or limited

• Cardiovascular exclusions are typically broad and long-lasting.
• Follow-up monitoring and medication are outside health insurance.
• Related conditions such as blood pressure may be swept into the same exclusion.

Nothing here is universal. Two insurers can take different views of the same history, and the same insurer can take different views on two products. The policy wording is the only thing that decides it.

What happens when you claim

• Critical illness claims are decided on the policy definition, including any severity wording.
• Health insurance claims are checked against the exclusion before authorisation.
• Emergency cardiac care is NHS provision throughout.

Insurers must handle claims promptly and fairly and must not turn a claim down unreasonably; the rules are in the FCA’s insurance conduct sourcebook. ^[1] If you think a decision is wrong, you can complain and then take it to the Financial Ombudsman Service free of charge. ^[2] Our complaints page sets out both routes.

The NHS route

Whatever an insurer decides, NHS care is unaffected: buying or being refused insurance changes nothing about your entitlement. Treatment on the NHS follows clinical guidance rather than policy wording. ^{[5] [4]} For information and support about the condition itself, the British Heart Foundation is a better place than an insurance site.

Questions to ask before you buy

1. Is the exclusion limited to the diagnosed condition or does it cover the cardiovascular system?
2. On a moratorium policy, exactly how far back does the look-back go, and how long must I be clear?
3. If I choose full underwriting instead, will you put the exclusion wording in writing before I pay?
4. Would the exclusion be reviewed later, and on what evidence?
5. Does the exclusion extend to related conditions and complications, or only to this one?

An adviser can answer those questions for your own history; we cannot, and we do not try to. Anyone advising you on insurance must be authorised, and you can check them on the Financial Services Register. ^[3] Free impartial guidance is also available from MoneyHelper. ^[6]
