Coronary Artery Disease Q & A

What is coronary artery disease?

Coronary artery disease is a type of heart disease that affects the supply of oxygen-rich blood to your heart due to damage or blockage in the coronary artery. In most cases, coronary artery disease results from the buildup of plaque along the artery wall. 

Plaque buildup occurs slowly over many years, which eventually causes a narrowing of the artery that reduces the supply of blood to your heart. If plaque from your artery breaks away from the wall, a blood clot forms, which may lead to a complete blockage of the artery, resulting in a heart attack. 

What are coronary artery disease symptoms?

Coronary artery disease develops over decades and you may not experience any symptoms until there’s significant blockage or you have a heart attack. Some of the symptoms include:


Angina is a type of chest pain associated with coronary artery disease. With angina, you may feel a tightness or pressure in your chest during physical or emotional stress. 

Shortness of breath

When your heart isn’t able to pump enough oxygen-rich blood to the rest of the organs in your body, you may experience shortness of breath. 

Heart attack

During a heart attack, you may experience a crushing sensation in your chest and pain in your left arm, neck, or jaw. If you think you’re having a heart attack, call 911 or go to the nearest emergency room. 

How is coronary artery disease diagnosed?

Modern Heart and Vascular Institute is a state-of-the-art cardiovascular practice that uses cutting-edge equipment to diagnose heart conditions like coronary artery disease.

During your exam, Dr. Agarwal asks detailed questions about your symptoms, medical and family history, and lifestyle habits, and then performs a physical.

To evaluate your heart, Dr. Agarwal may recommend various diagnostic tests, such as an echo-vascular stress test, CT scan, or PET scan, which he performs at the office. 

How is coronary artery disease treated?

Dr. Agarwal develops individualized treatment plans for the management of coronary artery disease based on the severity of your disease, your symptoms, and your medical history. However, the primary treatment for coronary artery disease centers around lifestyle changes, such as:

  • Heart-healthy diet
  • Exercise program
  • Stress management
  • Smoking cessation
  • Weight loss


If needed, Dr. Agarwal may also prescribe medications to improve your blood pressure or cholesterol levels. If the blockage is severe, Dr. Agarwal may suggest angioplasty with stenting or bypass surgery.
