Coronary Artery Disease
Coronary artery disease occurs when the blood vessels supplying your heart are damaged. Cholesterol in the coronary arteries and inflammation are usually the first causes.
Coronary artery disease (CAD) develops when the coronary arteries, which supply oxygen-rich blood to the heart, become narrowed or blocked. This usually happens because of a buildup of plaque made up of cholesterol, fatty substances and other materials inside the artery walls.
Over time, reduced blood flow can affect how the heart works and may cause chest pain, also known as angina. In some cases, coronary artery disease can lead to a heart attack or contribute to heart failure.
What Is Coronary Artery Disease?
The coronary arteries are the blood vessels that carry oxygen-rich blood to the heart muscle. When plaque builds up inside these arteries, they can become narrower and restrict blood flow to the heart.
This process is known as atherosclerosis. Plaque buildup may develop gradually over many years, and some people may not experience noticeable symptoms until blood flow becomes significantly reduced.
If a plaque ruptures, a blood clot may form and suddenly block the artery. This can cause a heart attack and damage the heart muscle.
Coronary artery disease may also be associated with other cardiovascular conditions, including angina, cardiac arrhythmia and heart failure.
What Causes Coronary Artery Disease?
The most common underlying cause of coronary artery disease is atherosclerosis, which occurs when plaque accumulates inside the coronary arteries.
Several conditions and lifestyle factors can contribute to this process, including:
Symptoms of Coronary Artery Disease
Some people with coronary artery disease do not experience symptoms, especially during the early stages. When symptoms develop, they may appear during physical activity or emotional stress, when the heart needs more oxygen.
Common symptoms include:
Seek emergency medical care immediately if you experience chest discomfort that is new, severe, persistent or occurs with shortness of breath, cold sweating, nausea, fainting or pain spreading to the arm, jaw or back. These may be signs of a heart attack. Call emergency services rather than driving yourself.
Risk Factors for Coronary Artery Disease
Several factors can increase the likelihood of developing coronary artery disease. Some cannot be changed, while others can be managed through medical care and lifestyle changes.
Risk factors include:
How Can Coronary Artery Disease Be Prevented?
Although not every case can be prevented, adopting healthy habits and managing medical conditions can help reduce the risk of coronary artery disease.
Some preventive measures include:
How Is Coronary Artery Disease Diagnosed?
There is no single test that is appropriate for every person with suspected coronary artery disease. A cardiologist evaluates symptoms, medical history, family history and cardiovascular risk factors before deciding which tests may be necessary.
Depending on the individual case, diagnostic tests may include:
The tests selected depend on each patient's symptoms, medical history and clinical evaluation.
Treatment for Coronary Artery Disease
Treatment aims to improve blood flow to the heart, manage symptoms, reduce the risk of complications and prevent the disease from progressing. The appropriate approach depends on the severity of the condition, the location of arterial blockages and the patient's overall health.
Lifestyle Changes
Healthy habits are an important part of managing coronary artery disease. A healthcare professional may recommend:
Depending on the patient's condition, a cardiologist may prescribe medications to manage risk factors, reduce symptoms or prevent complications. These may include:
Medical Procedures and Surgery
When coronary artery disease is severe or symptoms are not adequately controlled, a cardiologist may consider procedures to improve blood flow.
Depending on the patient's condition, options may include:

Frequently Asked Questions About Coronary Artery Disease
1. What is the main cause of coronary artery disease?
The most common cause is atherosclerosis, a process in which plaque made up of cholesterol, fatty substances and other materials builds up inside the coronary arteries and restricts blood flow.
2. Can coronary artery disease develop without symptoms?
Yes. Some people do not experience noticeable symptoms during the early stages. In other cases, symptoms may appear only during physical activity or when the disease has progressed.
3. Is coronary artery disease reversible?
Plaque buildup generally cannot be completely reversed. However, lifestyle changes and appropriate medical treatment can help manage the disease, reduce cardiovascular risk and prevent it from worsening.
4. How is coronary artery disease different from a heart attack?
Coronary artery disease is a condition in which the arteries supplying blood to the heart become narrowed or blocked. A heart attack occurs when blood flow to part of the heart muscle is suddenly reduced or blocked, causing damage.
5. Can coronary artery disease be prevented?
Not all cases can be prevented, but managing cholesterol, blood pressure and diabetes, avoiding tobacco, staying physically active and following a heart-healthy eating plan can help reduce the risk.
Over time, reduced blood flow can affect how the heart works and may cause chest pain, also known as angina. In some cases, coronary artery disease can lead to a heart attack or contribute to heart failure.

How Is Coronary Artery Disease Diagnosed?
There is no single test that is appropriate for every person with suspected coronary artery disease. A cardiologist evaluates symptoms, medical history, family history and cardiovascular risk factors before deciding which tests may be necessary.
Depending on the individual case, diagnostic tests may include:
- Electrocardiogram (ECG or EKG): Records the electrical activity of the heart and may reveal signs of a previous or ongoing heart attack or other cardiac conditions.
- Blood tests: May evaluate cholesterol levels, blood glucose and other markers that help assess cardiovascular risk or possible heart damage. Learn more about Clinical Laboratory services.
- Stress test: Evaluates how the heart responds to physical activity or medication that increases the heart's workload.
- Echocardiogram: Uses sound waves to create images of the heart and assess its structure and pumping function. Learn more about an echocardiogram.
- Coronary imaging or angiography: In selected cases, imaging tests may be used to examine the coronary arteries and identify areas of narrowing or blockage.
The tests selected depend on each patient's symptoms, medical history and clinical evaluation.
Treatment for Coronary Artery Disease
Treatment aims to improve blood flow to the heart, manage symptoms, reduce the risk of complications and prevent the disease from progressing. The appropriate approach depends on the severity of the condition, the location of arterial blockages and the patient's overall health.
Lifestyle Changes
Healthy habits are an important part of managing coronary artery disease. A healthcare professional may recommend:
- Following a heart-healthy eating plan.
- Engaging in regular physical activity as medically appropriate.
- Quitting smoking.
- Maintaining a healthy weight.
- Managing stress and getting adequate sleep.
- Monitoring blood pressure, cholesterol and blood glucose.
Depending on the patient's condition, a cardiologist may prescribe medications to manage risk factors, reduce symptoms or prevent complications. These may include:
- Cholesterol-lowering medications: Such as statins, which help lower LDL cholesterol and reduce cardiovascular risk.
- Antiplatelet medications: May be prescribed to reduce the risk of blood clots in selected patients.
- Beta-blockers: May reduce heart rate and blood pressure and help control certain symptoms.
- Other medications: Treatments for high blood pressure, diabetes, angina or other related conditions may also be necessary.
Medical Procedures and Surgery
When coronary artery disease is severe or symptoms are not adequately controlled, a cardiologist may consider procedures to improve blood flow.
Depending on the patient's condition, options may include:
- Angioplasty and stent placement: A catheter with a small balloon is used to widen a narrowed artery. A small mesh tube called a stent may be placed to help keep the artery open.
- Coronary artery bypass grafting (CABG): Surgery that uses a blood vessel from another part of the body to create a new route for blood to flow around a blocked coronary artery.
