Understanding Coronary Artery Disease (CAD)

Coronary artery disease (CAD) develops when plaque builds up inside the arteries that supply oxygen-rich blood to your heart. Over time, this buildup can narrow the arteries, restrict blood flow, and increase your risk of a heart attack and other cardiovascular complications.

The good news? Early detection, proactive prevention, and personalized treatment can help manage coronary artery disease and protect your long-term heart health.

Whether you’re experiencing symptoms or looking to better understand your cardiovascular risk, our cardiology team is here to help you take the next step toward a healthier heart.

What is Coronary Artery Disease (CAD)?

Coronary artery disease is one of the most common forms of heart disease. It occurs when fatty deposits, cholesterol, calcium, and other substances accumulate along the inner walls of the coronary arteries. This process, known as atherosclerosis, can cause the arteries to become narrowed or blocked.

When the heart doesn’t receive enough oxygen-rich blood, you may experience chest discomfort or shortness of breath. In some cases, plaque can rupture and trigger a blood clot that blocks blood flow, causing a heart attack.

CAD can develop gradually over many years, sometimes without noticeable symptoms. Understanding your risk and identifying potential problems early are important steps toward preventing serious complications.

What Are the Symptoms of Coronary Heart Disease?

Some people with coronary artery disease have no symptoms, particularly in the early stages. Others may experience symptoms during physical activity, emotional stress, or even at rest as the condition progresses.
Common symptoms include:

Chest pain or discomfort (angina): Pressure, tightness, squeezing, or heaviness in the chest.
Shortness of breath: Difficulty breathing during activity or at rest.
Unusual fatigue: Feeling excessively tired, sometimes with routine activities.
Dizziness or lightheadedness: Feeling faint or unsteady, particularly when accompanied by other symptoms.

Women, older adults, and people with diabetes may experience less typical symptoms, such as unusual fatigue, nausea, or shortness of breath, without prominent chest pain.

When to seek emergency care: New or severe chest discomfort, shortness of breath, cold sweats, nausea, or pain spreading to the arm, back, neck, or jaw may signal a heart attack. Call 911 immediately. Do not drive yourself to the hospital.

What Are the Risk Factors for Coronary Artery Disease?

Several factors can increase your likelihood of developing CAD. Some, such as age and family history, cannot be changed. Others can be addressed through lifestyle modifications and medical care.

Even if you feel healthy, you may have underlying risk factors that deserve attention. A comprehensive cardiovascular evaluation can help you better understand your individual risk and determine whether additional testing is appropriate.

High cholesterol

Elevated LDL cholesterol can contribute to plaque buildup in the arteries.

High blood pressure

Persistent hypertension can damage blood vessels over time.

Diabetes

High blood sugar can increase the risk of cardiovascular disease.

Smoking and tobacco use

Tobacco damages blood vessels and increases cardiovascular risk.

Family history

A family history of early heart disease may increase your risk.

Physical inactivity

Limited physical activity can contribute to other cardiovascular risk factors.

Excess weight

Overweight and obesity may increase the likelihood of high blood pressure, diabetes, and abnormal cholesterol.

Age

Cardiovascular risk generally increases as you get older.

How is Coronary Artery Disease Diagnosed?

Diagnosing coronary artery disease begins with understanding your symptoms, medical history, family history, and cardiovascular risk factors. Your cardiologist may recommend one or more tests based on your individual needs.

Diagnostic options may include:


Cardiovascular Evaluation A review of your health history, physical examination, blood pressure, and other clinical findings help establish your cardiovascular risk.		Blood Tests Cholesterol testing and other laboratory assessments can identify risk factors that contribute to coronary artery disease.		Coronary CT Angiography (CCTA) CCTA is a noninvasive imaging test that uses computed tomography and contrast material to create detailed images of the coronary arteries. It can help identify narrowing and plaque buildup, including disease that may not yet be causing symptoms.


Advanced Plaque Analysis When available and clinically appropriate, advanced plaque analysis can provide additional information about plaque characteristics and help inform cardiovascular risk assessment and treatment decisions.		Stress Testing Exercise or medication-based stress testing evaluates how your heart responds to increased workload and may help identify evidence of reduced blood flow.		Cardiac Catheterization In selected cases, an invasive procedure may be needed to examine the coronary arteries more closely and determine whether treatment is necessary.

Our cardiologist will recommend the most appropriate diagnostic approach based on your symptoms, risk profile, and clinical findings.

How Is Coronary Artery Disease Treated?

Although coronary artery disease is a chronic condition, treatment can help reduce cardiovascular risk, manage symptoms, and improve quality of life. Your treatment plan will depend on the severity of the disease, your overall health, and your individual goals.

Treatment may include:

Lifestyle Modifications

Heart-healthy habits can make a meaningful difference. These may include eating a balanced diet, exercising regularly as recommended by your care team, maintaining a healthy weight, avoiding tobacco, managing stress, and prioritizing sleep.

Medications

Depending on your needs, your cardiologist may prescribe medications to manage cholesterol, lower blood pressure, reduce the risk of blood clots, or relieve symptoms. Take medications as directed and discuss any concerns with your provider.

Cholesterol and Cardiovascular Risk Management

Managing LDL cholesterol, blood pressure, diabetes, and other contributing factors is essential to reducing the risk of disease progression and future cardiovascular events.

Minimally Invasive Procedures

For certain patients, coronary angioplasty and stent placement may help restore blood flow through narrowed arteries.

Coronary Artery Bypass Surgery

For more complex or extensive disease, coronary artery bypass grafting may be recommended to improve blood flow to the heart.

Our cardiologist will work with you to determine which treatment options are most appropriate for your condition.

Can CAD Be Prevented?

While not every case of coronary artery disease can be prevented, taking proactive steps can help lower your risk.

You can support your cardiovascular health by:

Scheduling regular checkups and recommended cardiovascular screenings.
Monitoring cholesterol, blood pressure, and blood sugar.
Eating a heart-healthy diet rich in vegetables, fruits, whole grains, and other nutrient-dense foods.
Staying physically active, with exercise tailored to your health and abilities.
Avoiding smoking and other tobacco products.
Taking prescribed medications consistently.
Discussing your family history and personal risk factors with your cardiologist.

If you have a family history of heart disease or other risk factors, don’t wait for symptoms to appear before discussing your cardiovascular health with a medical professional.
