Coronary Artery Disease Q & A

What is coronary artery disease?

Coronary artery disease is the most common form of heart disease. The condition is the result of a buildup of bad cholesterol within the arteries. This buildup causes the partial or total blockage of your arteries, reducing your blood’s ability to flow properly through your body.

What are the symptoms of coronary artery disease?

When your heart isn’t receiving an adequate supply of blood, you may experience discomfort or pain in your chest. You may also feel a burning sensation and frequent chest tightness or heaviness.

Other common symptoms of coronary artery disease include:

  • Sweating
  • Dizziness
  • Shortness of breath
  • Pain that radiates into your shoulders or arms

If blood flow to the heart is severely restricted, your heart muscle can begin to atrophy, and you may experience a heart attack. It’s critical that you not ignore these symptoms and seek medical attention if any of them last longer than five minutes.

How is coronary artery disease diagnosed?

To detect blood flow abnormalities in your heart, Dr. Markey may recommend the following tests:

Stress test

Detects stress on your heart while you’re physically active and while you’re resting by monitoring electrical activity in the heart muscle.


Uses electrical signals that travel through your heart to identify heart attacks.


An imaging test that uses ultrasound waves to create an image of your heart to detect abnormalities.

Cardiac catheterization

Dr. Markey injects a dye through a catheter into your arteries to detect blockages.

What treatments are available for coronary artery disease?

Dr. Markey creates a custom treatment plan to reduce your risk of developing coronary artery disease. He may recommend lifestyle changes, such as:

  • Losing weight
  • Eating a healthy diet
  • Quitting smoking
  • Increasing physical activity
  • Limiting alcohol consumption

If lifestyle changes aren’t effective in reducing your risk for coronary artery disease, you may need medication to reduce high cholesterol or control high blood pressure. For more serious cases, Dr. Markey may refer you to a surgical specialist who can widen blocked arteries and restore normal blood flow to your heart.
