Coronary Artery Disease Q&A

What is coronary artery disease?

Coronary artery disease (CAD) occurs when your coronary arteries become damaged or diseased as a result of fat and cholesterol buildup in your artery walls. Your coronary arteries supply blood to your heart, and when they become clogged with fat and cholesterol from your bloodstream, it sticks to the walls in your coronary arteries. This then makes it difficult for blood to flow freely through the arteries to your heart.

If the arteries become too narrow or blocked completely, your heart may not get the blood and oxygen it needs. As a result, you may experience chest pain or even a heart attack. Sometimes, a heart attack is the first sign that you even have coronary artery disease, and in many cases, it’s too late at that point to make lifestyle changes.

very measure to provide comprehensive testing for an accurate diagnosis of coronary artery disease. Your doctor may perform diagnostic testing that includes:

  • A thorough physical exam and family medical history

How does a coronary calcium scan diagnose coronary artery disease?

If you have a moderate risk for heart disease based on your health and family history, a coronary calcium scan provides vital information to your doctors before a serious or life-threatening situation occurs. A coronary calcium scan, or heart scan, is a specialized X-ray that shows images of your heart so the team of doctors can detect and measure plaque in your arteries.

The heart scan indicates the amount of calcified plaque you have, which can help identify if you’re at risk of coronary artery disease before you experience any symptoms. Essentially, a coronary calcium scan may indicate a need for lifestyle modifications or medications that can reduce your risk of a heart attack in the future.

How is CAD treated?

Treatments for coronary artery disease often include committing to making healthier lifestyle choices to promote artery and heart health, including:

  • Reducing stress
  • Quitting smoking
  • Losing weight
  • Managing other health conditions
