It’s a well-known fact that heart disease impacts the health of millions of people worldwide, but its connection to hearing loss is often misunderstood. A common misconception is that hearing loss can lead to heart disease. However, the relationship between these two conditions is more complicated.
In this article, we’ll explore the links between heart disease and hearing loss, demystify the misconceptions, and provide strategies for prevention.
What Is CVD?
CVD is an abbreviation for cardiovascular disease, which refers to any disorder of the heart and blood vessels. When a doctor mentions “heart disease,” they’re using a simpler term that’s easier to understand. But heart disease is the same as cardiovascular disease.
Types of CVD
Heart disease isn’t just one condition; it’s a broad term for various illnesses that affect the heart and blood vessels. Each relates to different aspects of CVD, showing just how complex heart-related challenges can be.
This general definition can be narrowed down to four basic categories of CVD:
Coronary Artery Disease (CAD) or Coronary Heart Disease (CHD) includes angina (chest pain), myocardial infarction (heart attack), and heart failure.
Cerebrovascular Disease (CVD) includes stroke and mini-stroke, which is also called transient ischemic attack (TIA).
Peripheral Artery Disease (PAD) reduces blood flow to the legs, which can be painful, especially while walking.
Aortic Atherosclerosis includes thoracic aortic aneurysm (chest area) and abdominal aortic aneurysm (abdominal area).
CAD is the most common form, accounting for one-third to one-half of all cases of CVD.
Impact of CVD
The impact of CVD is as vast and varied as the conditions it includes. In the U.S., heart disease is the leading cause of death:
One person dies every 33 seconds from heart disease.
One in every five deaths is related to heart disease.
In 2021 alone, about 695,000 Americans died from heart disease. This alarming number reflects the widespread severity of CVD.
Causes of CVD
CVD is typically associated with atherosclerosis (hardening of the arteries). Atherosclerosis occurs when plaque (fats, cholesterol, and other substances) builds up in artery walls. This condition makes it difficult for blood to flow through the narrowed, hardened arteries. When a blood clot forms, it can block blood flow and lead to a heart attack or stroke.
Many factors influence the risk of heart disease, including medical conditions, lifestyle factors, and genetic factors.
Medical Conditions
High Blood Pressure (Hypertension): Elevated blood pressure can cause hardening and thickening of the arteries and reduce blood flow.
High Cholesterol (LDL): High levels of bad cholesterol can lead to plaque buildup in your arteries.
Diabetes: High blood sugar can damage blood vessels.
Lifestyle Factors
Unhealthy Diet: Consuming high amounts of saturated fats, trans fats, and processed sugars can cause high cholesterol and plaque buildup.
Physical Inactivity: Lack of regular exercise contributes to poor heart health.
Smoking: Tobacco use damages the lining of the arteries and leads to the accumulation of fatty material.
Excessive Alcohol: Drinking too much alcohol can raise blood pressure.
Stress: Chronic stress can cause damage to the arteries.
Genetic Factors
Family History: Some people may have a genetic predisposition.
Age and Gender: The risk of CVD increases with age, with men having a generally higher risk at a younger age compared to women.
Ethnicity: Certain ethnic groups are often more susceptible due to genetic and socioeconomic factors.
Symptoms of CVD
The symptoms of cardiovascular disease can vary widely depending on the specific type of heart condition. Recognizing these symptoms is crucial for early detection and effective management.
Here are some common symptoms associated with different forms of heart disease, including heart attack, stroke, arrhythmia, and heart failure.
General Symptoms
Chest pain or discomfort
Shortness of breath
Unexplained fatigue and exhaustion
Symptoms of Heart Attack
Intense chest pain
Pain extended to the shoulders, arms, back, neck, or jaw
Sudden cold sweats without physical exertion
Nausea or vomiting
Dizziness or lightheadedness
Symptoms of Stroke
One side of the face droops or becomes numb
Sudden weakness in one arm or side of the body
Trouble speaking or slurred speech
Trouble seeing in one or both eyes
Difficulty with walking and balance
Symptoms of Arrhythmia
Feeling like the heart is racing, pounding, or fluttering
Heart beating too fast, too slow, or irregularly
Fainting spells
Symptoms of Heart Failure
Swelling in legs, ankles, and feet
Persistent cough or wheezing
Increased need to urinate at night
It’s vital to seek immediate medical attention when experiencing symptoms of CVD. Early identification can lead to a timely diagnosis, better management, and reduced risk of complications.
How Hearing Loss and CVD Are Connected
Our heart and ears may seem like separate entities, but understanding how these two vital organs are linked is important for overall well-being. Here’s a straightforward look at why heart problems can impact hearing.
Blood Flow and the Inner Ear
Heart disease can make blood flow difficult because it narrows, hardens, or blocks arteries. The inner ear is sensitive to these changes because it relies on a steady blood flow to function. It can get damaged when the blood flow drops, which may lead to hearing loss.
Oxygen and Ear Health
The inner ear needs a steady oxygen supply to keep its nerve cells healthy. These cells are responsible for sending sound information to the brain. If heart disease reduces the oxygen available to these cells, the nerves can become damaged, which weakens your hearing.
Inflammation and Hearing
Heart disease often comes with inflammation, a response by the body that can also affect the ears. This inflammation can damage the pathways in the ear that help us hear.
Long-Term Effects of CVD
Heart Disease and Hearing Loss
A Scientific Reports study found that people with heart disease-related conditions (e.g., diabetes, high blood pressure, etc.), as well as those who smoke, are more likely to experience hearing loss. Additionally, those with two or more major CVD risk factors face a higher likelihood of hearing impairment compared to those without these risk factors.
Stroke and Sudden Hearing Loss
Recent research highlights that sudden sensorineural hearing loss (SSNHL) might signal a higher risk of stroke. This sudden hearing loss occurs in one ear, often due to serious vascular issues. The inner ear needs a steady blood flow to function properly. If blood supply is suddenly reduced due to a blockage, it can affect hearing and increase the risk of stroke.
Stroke and Tinnitus
Tinnitus ("ringing in the ears") is often linked to age-related hearing loss or noise exposure. It can also suggest more serious conditions like cardiovascular disease or an impending stroke. This is especially true if the ringing in the ears is accompanied by sudden hearing loss or dizziness.
Prevention Strategies
Adopting a heart-healthy lifestyle can help you reduce the risk of heart disease, strokes, and hearing loss.
Here are some ways to take care of your heart and hearing:
Get regular screenings: Regular medical check-ups to monitor heart and vascular health can help catch early signs of trouble.
Make healthy lifestyle choices: Maintaining a balanced diet, staying physically active, avoiding smoking, and drinking alcohol in moderation can significantly reduce the risk of heart disease.
Managing chronic conditions: Effectively controlling hypertension, diabetes, and high cholesterol with medication and lifestyle changes is critical.
Monitor your hearing health: Regular hearing exams, especially for those experiencing tinnitus or sudden hearing loss, can be vital for the early detection of potential vascular issues.
By following these tips and taking proactive steps, you can protect both your cardiovascular and auditory health.

Understanding the connection between your heart and ears is essential. While hearing loss doesn’t cause heart disease, it could be an indicator of the presence or potential development of cardiovascular disease. Heart disease can also lead to circulatory problems and, in turn, contribute to hearing impairment. That’s also why caring for your heart health is crucial to preventing hearing loss.
