Sleep apnea is a serious condition in which a person stops breathing during sleep.

CSA Risk Factors
Certain factors put you at increased risk of CSA:1

Heart Disorders:
People with heart failure or heart rhythm disorders such as atrial fibrillation

Brain Conditions:
Certain brain conditions such as stroke or tumor can impair the brain’s ability to regulate breathing

Males are more likely to develop CSA than females

Over 65 years of age

CSA Symptoms2

Breathing that temporarily stops while asleep

Shortness of breath at night

Difficulty concentrating

Nighttime urination

Daytime fatigue

Decreased stamina

Healthy vs. Disrupted Breathing

During healthy sleep, the brain controls breathing by sending the proper signals to the muscles that control breathing. For adults with CSA, the brain fails to send appropriate signals to these muscles.

CSA and Heart Health

CSA is common in cardiac patients, primarily patients with heart failure. CSA causes a repeating cycle of disruptive breathing, nighttime wakefulness and increased activation of the body’s sympathetic nervous system (“fight or flight response”) that contribute to heart failure.2

Studies have shown that patients with CSA are at risk for heart rhythm disturbances, high blood pressure, and worsening heart failure.3 Speak with your physician today to learn about your risks.

Diagnosing CSA

CSA frequently occurs among people who also have other diseases such as chronic heart failure, atrial fibrillation, stroke and may be seen in patients with chronic kidney disease and diabetes.2 As a result, symptoms can be subtle and often overlap.

To diagnose CSA, a physician will prescribe a home or in-lab sleep study to determine whether the sleep disturbance results from inappropriate signals from the brain (CSA) or an airway blockage (OSA).
