Yes. At The NY Center for the Prevention of Heart Disease we see that sleep apnea raises the risk of high blood pressure, atrial fibrillation, stroke and heart attack, and it often makes existing heart disease harder to control. Below we explain how sleep apnea affects the cardiovascular system, who is most likely to be affected, how we evaluate the problem in a cardiology setting, and what to expect from treatment and coordination with sleep medicine specialists.
How sleep apnea increases heart risk
Obstructive sleep apnea causes repeated pauses in breathing during sleep. Each pause lowers oxygen levels briefly and triggers a surge of stress hormones. Over weeks to years those surges change blood pressure regulation, increase inflammation, and make the heart work harder.
Clinically we see the effects as higher systolic blood pressure, new or worsening atrial fibrillation, worsening heart failure symptoms, and a higher long term risk of stroke and heart attack. The American Heart Association and sleep medicine organizations describe these links and recommend evaluation when cardiovascular problems occur alongside symptoms of sleep apnea.
Who is most at risk in the Times Square area
Sleep apnea can affect adults of any age, but certain factors raise the chance that breathing pauses are present and clinically important.
- Excess weight or central obesity
- Loud snoring and witnessed apneas reported by a bed partner
- Daytime sleepiness, falling asleep while driving, or poor daytime concentration
- Existing conditions we follow frequently, including hypertension, diabetes, coronary artery disease and atrial fibrillation
- Older age and male sex, though many women over 45 are affected as well
In our practice we treat adults from throughout Manhattan and the greater New York area. If you live or work near Times Square and have the risk factors above, sleep apnea should be on the list when we assess cardiovascular risk. For information about our service locations see our locations listing on the site at the locations hub.
How we evaluate sleep apnea in a cardiology consult
When a patient has cardiovascular disease or unexplained high blood pressure, we ask targeted questions about sleep and daytime function. Our evaluation typically includes a focused history, a physical exam, and screening tools that estimate the probability of sleep apnea.
We do not perform sleep studies in the cardiology clinic. Instead we coordinate testing and interpretation with sleep medicine specialists. Common elements in our pathway include:
- Initial screening. We review symptoms such as loud snoring, witnessed pauses, and excessive daytime sleepiness, and we assess comorbid conditions like hypertension and diabetes.
- Cardiac risk assessment. We check blood pressure control, review medications, and when indicated we order ambulatory cardiac monitoring or imaging to understand the heart s current status.
- Referral for diagnostic testing. For suspected sleep apnea we arrange either home sleep apnea testing or an in lab polysomnogram with a sleep medicine partner, depending on clinical complexity.
- Coordinated care planning. After test results are available we work with the sleep team to align therapy with cardiovascular goals, and we follow the patient for changes in blood pressure, arrhythmias and symptoms.
Pro tip: If you have atrial fibrillation that recurs despite usual care, sleep apnea is a common and treatable contributor. Ask your cardiology team to consider screening and testing as part of rhythm management.
Treatment pathways and how treatment changes heart risk
Treatment for obstructive sleep apnea is most often managed by sleep medicine specialists and includes positive airway pressure therapy among other options. From a cardiology perspective our goal is to reduce the cardiovascular effects of disordered breathing and to optimize blood pressure and rhythm control.
Treatment of sleep apnea can lower nighttime and daytime blood pressure, and it may reduce the frequency of atrial fibrillation episodes. We coordinate closely with sleep medicine when therapy is started, because changes in sleep breathing can alter heart rate, blood pressure and tolerance for certain cardiac medications.
When we consider treatment we weigh factors such as severity of sleep apnea, presence of heart disease, symptoms, and the patient s ability to use prescribed devices. For patients focused on prevention we work inside our preventive cardiology program to align lifestyle changes, risk factor control and sleep disorder management.

Signs that should prompt evaluation by a heart specialist and a sleep team
Prioritize evaluation if you have any of these
- Persistent high blood pressure despite two or more medications
- New or recurrent atrial fibrillation
- Unexplained daytime sleepiness with cardiovascular risk factors
- Worsening heart failure symptoms without clear cause
- Multiple risk factors such as diabetes, obesity and family history of heart disease
We treat patients across Manhattan, the Bronx, Queens, Brooklyn, Westchester, Long Island and New Jersey. If you are wondering whether sleep apnea is a factor in your heart health, our team can help decide whether testing and coordinated care with sleep medicine are appropriate. See our heart specialist service page for more about the scope of our cardiology care.
Watch out: Do not assume snoring is harmless. Loud snoring with daytime sleepiness is a clinical sign and merits evaluation, because untreated sleep apnea can worsen blood pressure and increase stroke risk.
Common questions we hear in the clinic
Below are the questions our patients ask most often, and how we address them in practice.
- Will treating sleep apnea remove my heart risk? Treatment lowers certain risks and often improves blood pressure and arrhythmia control, but it is one element of a broader prevention plan.
- Who manages the sleep study and therapy? We collaborate with sleep medicine for diagnostic testing and device selection, and we continue to manage cardiovascular effects.
- Is testing safe if I have heart disease? Yes, both home testing and in lab polysomnography are frequently used when cardiac disease is present, and we coordinate scheduling and monitoring as needed.
Key takeaway
Sleep apnea is a modifiable contributor to high blood pressure, atrial fibrillation, stroke and heart attack. We evaluate sleep symptoms as part of cardiovascular risk assessment, coordinate testing with sleep medicine specialists, and integrate treatment into individualized preventive cardiology plans to lower overall heart risk.
Frequently asked questions
How does sleep apnea cause high blood pressure?
Repeated nighttime drops in oxygen and frequent arousals increase sympathetic nervous system activity and stress hormones, which over time raise resting blood pressure and make hypertension harder to control.
Can treating sleep apnea reduce atrial fibrillation?
Treating sleep apnea often lowers the burden of atrial fibrillation and improves outcomes after rhythm procedures, but individual results vary. We evaluate rhythm history and coordinate care with electrophysiology and sleep colleagues to create an integrated plan.
What kind of sleep test should I expect?
For many adults without complicated lung or cardiac disease a home sleep apnea test is sufficient. If the clinical picture is complex we refer for in lab polysomnography. We decide the right route together with sleep medicine based on your cardiac history and symptoms.
Will my cardiology medications change if I have sleep apnea?
Treatment of sleep apnea can change blood pressure and heart rate, so we may adjust medications as needed. Medication changes are based on follow up measurements and overall risk management.
Are there lifestyle steps that help both sleep apnea and heart risk?
Yes. Weight loss when appropriate, regular physical activity, reducing alcohol before bedtime and quitting smoking all reduce sleep apnea severity and lower cardiovascular risk as part of a broader prevention plan.
