Overview
Your provider will likely recommend an imaging test, especially if:
- Your headaches last more than a few hours
- Your headaches strike suddenly, like a thunderclap
- You’re older than age 40
- You have other signs and symptoms, such as nausea, vomiting or vision disturbances
In these cases, different types of imaging tests can help your provider verify that you have the harmless variety of exercise headache, rather than the type caused by a structural or vascular irregularity.
- Magnetic resonance imaging (MRI). This test uses a magnetic field and radio waves to create cross-sectional images of the structures within the brain.
- Magnetic resonance angiography (MRA) and computerized tomography (CT) angiography. These tests visualize the blood vessels leading to and inside the brain.
- computed tomography (CT) scan. A CT scan uses X-rays to generate a cross-sectional image of the brain. This test can show fresh or recent bleeding into or around the brain and is often used if your headache occurred less than 48 hours beforehand.
Sometimes a spinal tap (lumbar puncture) is needed as well, especially if the headache started abruptly and very recently and brain imaging appears normal.

Symptoms
Complications
Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.
The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:
- High blood pressure.
- Diabetes.
- Heart failure.
- Some types of heart valve disease.
Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.
Prevention
Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:
- Control high blood pressure, high cholesterol and diabetes.
- Don't smoke or use tobacco.
- Eat a diet that's low in salt and saturated fat.
- Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
- Get good sleep. Adults should aim for 7 to 9 hours daily.
- Maintain a healthy weight.
- Reduce and manage stress.
