Awake to Heart Risks: Sleep Apnea’s Threat to Cardiovascular Health
You may know that sleep apnea can cause loud snoring and leave you feeling exhausted, even after a full night’s sleep. However, are you aware of the cardiovascular consequences of sleep apnea? Sleep apnea is a condition that not only disrupts your sleep but also poses serious risks to your heart health.
At Birth & Fletcher Orthodontics, Fort Worth, TX, sleep dentist Dr. Sheila Birth and her team want patients to understand the link between sleep apnea and heart health, and how seeking proper treatment for sleep apnea can improve the cardiovascular system, potentially saving lives.

How Does Sleep Apnea Affect Cardiovascular Health?
Heart Disease
For those with sleep apnea, it can act as a significant risk factor for developing heart disease. When breathing is repeatedly interrupted during sleep, the body experiences drops in oxygen levels and an increased strain on the heart. This chronic strain can lead to structural changes in the heart and an increased risk of heart failure, arrhythmias, and other cardiovascular complications.
High Blood Pressure
Obstructive sleep apnea is strongly linked to high blood pressure (hypertension). These repeated sleep apnea episodes of airway obstruction and reduced oxygen levels cause the body to release stress hormones, which can raise blood pressure levels. Untreated sleep apnea can make existing high blood pressure more difficult to control, increasing the risk of heart attack, stroke, and other cardiovascular events.
Stroke
Individuals with sleep apnea have an increased risk of stroke, particularly ischemic stroke, which is caused by a blocked artery in the brain. The combination of reduced oxygen levels, high blood pressure, and other physiological changes associated with sleep apnea can contribute to the development of blood clots and damage to blood vessels, leading to a higher stroke risk.
Endothelial Dysfunction
The endothelium is the inner lining of blood vessels, and its proper functioning is crucial for regulating blood flow and preventing cardiovascular disease. Sleep apnea has been shown to impair endothelial function, which can lead to atherosclerosis (hardening of the arteries) and an increased risk of heart attack and stroke.
Arrhythmias
Untreated sleep apnea can disrupt the heart’s normal electrical activity, leading to irregular heartbeats or arrhythmias. These arrhythmias can range from relatively harmless palpitations to more serious conditions like atrial fibrillation, which can increase the risk of stroke and other complications.
Coronary Artery Disease (CAD)
Coronary artery disease, or CAD, is a leading cause of heart attacks and is characterized by a buildup of plaque in the arteries that supply blood to the heart. Sleep apnea has been identified as an independent risk factor for CAD, likely due to the increased inflammation, oxidative stress, and endothelial dysfunction associated with the condition.
Diastolic Dysfunction and Heart Failure Risk
Sleep apnea can contribute to diastolic dysfunction, a condition where the heart muscle struggles to relax properly between beats. This impairment in relaxation can lead to inadequate filling of the heart chambers, ultimately increasing the risk of heart failure over time as the heart’s pumping ability becomes compromised.
Increased Blood Viscosity and Clotting Risk
Repeated drops in oxygen levels during sleep apnea can lead to the thickening of blood, a phenomenon known as increased blood viscosity. This thicker blood requires more effort from the heart to pump, increasing strain on the cardiovascular system and elevating the risk of blood clot formation, which can lead to serious complications such as stroke or pulmonary embolism.
Sympathetic Nervous System Activation and Chronic Stress
Sleep apnea triggers the body’s “fight-or-flight” response, leading to the release of stress hormones such as adrenaline. This chronic activation of the sympathetic nervous system can continuously elevate heart rate, constrict blood vessels, and raise blood pressure, placing further strain on the heart and contributing to the development or exacerbation of cardiovascular conditions.
Increased Oxidative Stress and Tissue Damage
Sleep apnea can weaken the body’s natural defenses against free radicals, damaging molecules that can cause oxidative stress. This increased oxidative stress can lead to inflammation and damage to blood vessels and heart tissue, contributing to the progression of cardiovascular diseases such as atherosclerosis, high blood pressure, and coronary artery disease.
Worsening of Existing Cardiovascular Conditions
For individuals who already have cardiovascular conditions, such as heart failure or coronary artery disease, untreated sleep apnea can exacerbate these conditions and increase the risk of adverse events. The more severe sleep apnea is, the greater the worsening of cardiovascular disease and other cardiovascular consequences tends to be.
Cardiovascular Benefits of Treating Sleep Apnea
Not only does treating sleep apnea lead to you feeling more rested each day, but it also provides the following cardiovascular benefits:
Improved Blood Pressure Control: Treating sleep apnea can help lower blood pressure levels, reducing the strain on the heart and blood vessels.
Reduced Risk of Heart Disease and Stroke: By addressing the underlying issues of oxygen deprivation and sleep disruption, treating sleep apnea can lower the risk of developing heart disease, stroke, and other cardiovascular complications.
Better Management of Existing Cardiovascular Conditions: For patients with existing heart conditions, treating sleep apnea can improve the overall management and outcomes of these conditions.
Improved Endothelial Function: Treating sleep apnea can help restore proper endothelial function, which is crucial for maintaining healthy blood vessels and preventing atherosclerosis.
Reduced Risk of Arrhythmias: By addressing the sleep-related factors that contribute to irregular heartbeats, treating sleep apnea can help reduce the risk of arrhythmias and their associated complications.
Enhanced Quality of Life: By improving sleep quality and alleviating the symptoms of sleep apnea, treatment can lead to increased energy levels, better cognitive function, and an overall improved quality of life.
Enhanced Exercise Tolerance: Addressing sleep apnea can improve oxygen delivery to tissues, leading to better exercise tolerance and cardiovascular fitness, which is crucial for overall heart health.
Reduced Inflammation: Treating sleep apnea can help decrease inflammation, further protecting the heart and blood vessels.
Metabolic Benefits and Diabetes Risk Reduction: Untreated sleep apnea is closely linked to an increased risk of metabolic disorders, including type 2 diabetes mellitus. Treating sleep apnea may improve insulin sensitivity and glucose metabolism, reducing the risk of developing type 2 diabetes and other metabolic conditions.
Improved Blood Vessel Reactivity and Circulation: Untreated sleep apnea can impair the ability of blood vessels to widen, or dilate, in response to increased blood flow, a process known as vasodilation. Treating sleep apnea may help restore normal blood vessel function, allowing for improved vasodilation and better blood circulation throughout the body, which is crucial for overall cardiovascular health.
