Atrial fibrillation and life insurance

Better news than most people expect

Atrial fibrillation is an irregular heart rhythm arising in the upper chambers of the heart. It is common, it becomes more common with age, and life insurers see it frequently.

Where the heart is otherwise structurally normal and stroke risk is being managed, offers are regularly made and the terms are often reasonable. Applicants often arrive expecting the worst because they associate AFib with stroke, and the underwriting reality is usually gentler than that.

What determines the outcome is less the rhythm and more what sits underneath it.

The pattern of episodes

Underwriters distinguish between the forms, and the labels come from your cardiologist’s records.

Paroxysmal, where episodes come and go and the rhythm returns to normal on its own. Generally the most favourably assessed.

Persistent, where an episode continues until treatment restores normal rhythm.

Permanent, where the rhythm is accepted as ongoing and the focus shifts to rate control and stroke prevention.

Frequency and duration of episodes matter within each of these. Someone with two brief episodes in five years presents differently from someone with frequent prolonged ones, even under the same label.

The heart underneath

This is the distinction that drives most of the variation in outcomes.

Lone AFib describes the rhythm occurring in a heart that is otherwise structurally normal, with no valve disease, no coronary artery disease and normal pumping function. Assessed on its own, this is often a modest factor.

AFib with structural heart disease is a different file. Where an echocardiogram shows valve disease, an enlarged left atrium, or reduced ejection fraction, the assessment reflects that underlying condition as much as the rhythm. In those cases the relevant considerations may be those in coronary artery disease.

If you have had an echocardiogram, its findings are among the most useful things in your file. Knowing roughly what it showed is worth doing before applying.

Stroke risk and anticoagulation

The reason AFib matters clinically is that it raises the risk of stroke, and underwriters assess how that risk is being handled.

Being on an anticoagulant is a positive in the file. It indicates the risk has been recognized and is being addressed. Applicants sometimes worry that blood thinners look bad; the opposite is closer to the truth, and an underwriter would rather see AFib anticoagulated than not.

What does change the assessment substantially is a stroke or TIA that has already occurred. At that point the file is assessed on those terms as well, and the relevant page is life insurance after a stroke.

Cardiologists use scoring systems to estimate stroke risk from factors including age, blood pressure, diabetes, heart failure and prior stroke. Underwriters look at the same factors, which is one reason AFib alongside several of them is assessed more cautiously than AFib alone.

Ablation

Catheter ablation aims to stop the abnormal rhythm at its source. Insurers take an interest in it and treat it carefully.

A successful ablation followed by a sustained period in normal rhythm can improve an assessment, sometimes materially. What underwriters want is time and evidence: enough months or years afterwards to show the rhythm has not returned, documented in follow-up records.

Applying shortly after an ablation is usually premature. The procedure is recent, recurrence is most likely early, and the underwriter has nothing to assess yet. A postponement is the common result.

Repeat ablations for recurrent AFib are noted, and they indicate a rhythm that has proven harder to control.

The things that travel with it

Blood pressure. Frequently present alongside AFib and assessed together. See high blood pressure.

Thyroid function. An overactive thyroid can cause or contribute to AFib, and where that was the trigger and has been treated, the picture is different from AFib with no identified cause. See thyroid conditions.

Alcohol. Heavy alcohol use is a recognized contributor, and where an application shows both, underwriters read them together. See alcohol history.

Sleep apnea. Commonly associated with AFib, and where present it is assessed on its own terms too. See sleep apnea.

Applying

Have the specifics: which pattern you have, when it was diagnosed, what medication you take including any anticoagulant, whether you have had an ablation and when, what your last echocardiogram showed, and your cardiologist’s name.

Apply fully underwritten. AFib is one of the conditions where insurers reach different conclusions on similar files, particularly on lone AFib and on post-ablation cases, so a single application is a poor way to find out what the market will do.

If an offer comes back rated, ask whether it can be reviewed later. Ratings on AFib are among those insurers will reconsider where the record shows sustained stability. See ratings and substandard offers.

Nothing here is medical guidance. Your rhythm management, your anticoagulation and your follow-up are your cardiologist’s territory, and those decisions matter regardless of any insurance file.
