Does atrial fibrillation get worse as I grow older?

Question

Hello doctor,

I am 70 and was diagnosed with atrial fibrillation several years ago after episodes of a racing heartbeat and dizziness. Medications help somewhat, but recently the irregular rhythms seem more frequent again, especially when I am tired or stressed. That is why I keep asking, does AFib get worse as I grow older at age 70?

Because I am worried the condition is gradually progressing, no matter what I do. I have already reduced caffeine, monitor my blood pressure carefully, and take anticoagulants exactly as prescribed, though the unpredictability still scares me sometimes.

A close friend recently had a stroke related to AFib, which honestly increased my anxiety about every skipped heartbeat sensation. My cardiologist mentioned age can affect rhythm stability, but I forgot to ask how much worsening is considered expected over time.

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

It is a disease of abnormal rhythm generated from the atria. Atrial fibrillation (AFib) can become more frequent or persistent as people get older, so some progression over time is not unusual.

Age-related changes in the heart, along with conditions such as:

High blood pressure.
Heart disease.
Sleep apnea.
Diabetes.

These can make atrial fibrillation (AFib) episodes occur more often or last longer. However, worsening is not inevitable, and many people in their 70s and beyond maintain good control of their atrial fibrillation (AFib) with medications, lifestyle measures, and regular follow-up with their cardiologist.

Since you are taking your anticoagulant as prescribed, you are significantly reducing your risk of stroke, which is one of the most important aspects of atrial fibrillation (AFib) treatment.

If you are noticing:

More frequent palpitations.
Dizziness.
Fatigue.
Irregular heartbeats.

It would be worthwhile to discuss this with your cardiologist, as adjustments to medications or additional treatments may help improve rhythm control and quality of life.

Anxiety after seeing a friend experience a stroke is understandable, but staying compliant with treatment and monitoring is one of the best ways to protect your health.

I hope you are satisfied with my answer.
