What is Coronary Artery Calcification? Risks and Prevention Tips

Coronary artery calcification (CAC) is a condition where calcium deposits build up in the coronary arteries, which supply blood to the heart. This accumulation of calcium can lead to the development of coronary artery disease (CAD), increasing the risk of heart attacks and strokes. 

In this post, we will see what coronary artery calcification is, its types, causes, symptoms, and how it differs from atherosclerosis. We will also take a look at the diagnostic tests, treatment options, and lifestyle changes that can help manage and prevent CAC.

What Is Coronary Artery Calcification?

Coronary artery calcification (CAC) is a condition where calcium deposits build up within the walls of the arteries that supply your heart. This buildup shows how much atherosclerotic plaque is present in your arteries, serving as an indicator of heart disease. 

CAC can be detected through imaging tests, helping to assess the risk of developing cardiovascular diseases. As the calcification progresses, it can lead to decreased flexibility of the arteries, potentially causing restricted blood flow to your heart.

Two Types of Coronary Artery Calcification

While discussing coronary artery calcification, it's essential to recognise the two types of this condition: intimal and medial calcification. Understanding these coronary artery calcification types can help in identifying the associated risks and appropriate preventive measures.

• Intimal Calcification:
  • Occurs in the inner layers of the artery walls.
  • Closely linked with atherosclerosis, which involves the buildup of fats, cholesterol, and other substances.
  • Can lead to significant narrowing and hardening of the arteries, increasing the risk of heart attack and strokes.
• Medial Calcification:
  • Involves the middle layer of the artery wall.
  • Generally seen in patients with metabolic disorders such as diabetes or kidney disease.
  • Does not necessarily obstruct blood flow but can lead to artery stiffness and increased blood pressure.

Coronary Artery Calcification Vs. Atherosclerosis

Both coronary artery calcification and atherosclerosis are crucial markers of heart health, but they differ in important ways. Here is a brief table to help you understand these differences:

By knowing these distinctions, you can better comprehend the implications of each condition on your heart health.

Who Does Coronary Artery Calcification Affect?

Coronary artery calcification (CAC) primarily affects individuals who are at a higher risk of cardiovascular disease. This includes older adults, typically those over the age of 40, as the likelihood of calcification increases with age. People with a family history of heart disease are also more susceptible, as genetic factors can play a significant role. 

Lifestyle factors such as smoking, a diet high in saturated fats, and a sedentary lifestyle further elevate the risk. Also, individuals with chronic conditions like diabetes, hypertension, and high cholesterol are more prone to develop CAC due to the strain these conditions place on the cardiovascular system.

How Does Coronary Artery Calcification Affect My Body?

Coronary artery calcification is an indicator of the extent of atherosclerotic plaque within the coronary arteries. This calcification can lead to the hardening of your arteries, reducing their elasticity and ability to dilate, which is crucial for regulating blood flow to your heart. 

Over time, this can strain your heart, reducing its efficiency and potentially leading to significant cardiovascular issues, including coronary heart disease and heart failure.

What Are The Coronary Artery Calcification Symptoms?

Identifying coronary artery calcification symptoms can be challenging, as they often do not manifest until the condition has progressed significantly. However, being aware of the potential signs can help in early detection and management.

• No Symptoms Initially: In many cases, CAC does not present any symptoms until there is considerable obstruction or a heart event.
• Chest Pain or Discomfort: One of the first noticeable coronary artery calcification symptoms might be angina, which can feel like pressure or a squeezing pain in your chest, typically triggered by physical activity or stress.
• Breathlessness: Another symptom can be shortness of breath, especially during activities that you once found easy.
• Fatigue: Feeling unusually tired, especially with exertion, can also be a sign of CAC affecting your heart’s ability to pump efficiently.

What Are The Coronary Artery Calcification Causes?

Being aware of the coronary artery calcification causes is essential for both prevention and treatment. The causes of CAC are multifaceted, involving both lifestyle and genetic factors.

• Ageing: As you age, your arteries can naturally stiffen and accumulate calcium.
• High Cholesterol Levels: High levels of low-density lipoprotein (LDL) cholesterol in the blood can lead to plaque buildup, which over time can become calcified.
• Hypertension: High blood pressure can damage the artery walls, promoting calcification.
• Diabetes: Diabetes significantly increases the risk of calcification due to the higher likelihood of fatty deposits in the arteries.
• Smoking: Tobacco use is a powerful risk factor for many heart diseases, including CAC, as it accelerates the calcification and hardening of the arteries.

What Tests Will Be Done To Diagnose Coronary Artery Calcification?

To diagnose coronary artery calcification (CAC), your doctor will likely recommend specific tests that provide detailed images of your heart and blood vessels. These tests help in assessing the amount of calcium in your arteries, thus indicating the presence of CAC.

• CT Heart Scan: A computed tomography (CT) scan of the heart is the most common test used to diagnose CAC. This scan is quick, non-invasive, and provides a clear picture of the extent of calcification within the coronary arteries.
• Electron Beam Computed Tomography (EBCT): This type of CT scan is particularly effective at capturing high-speed images of the heart, making it highly useful for detecting calcium deposits.
• Ultrafast CT Scan: Similar to EBCT, this method can detect even small amounts of calcium in the coronary arteries.
• Standard X-rays: While less detailed for this purpose, x-rays might be used as a preliminary tool before proceeding to more specific imaging techniques.

Coronary Artery Calcification Scores

Understanding your coronary artery calcification scores is crucial in managing your heart health. These scores are derived from imaging tests and provide a quantitative measure of the calcification within your coronary arteries.

• Scoring System: The amount of calcium is scored based on the extent of observed calcified plaque. A score of zero indicates no calcification, which suggests a low risk of coronary artery disease.
• Interpretation: Scores can range from mild to severe calcification, with higher scores indicating greater amounts of calcium and a higher risk of coronary artery disease.
• Risk Assessment: Your doctor will use this score to assess your risk of future heart events and to guide treatment decisions. The higher your score, the more vigilant you need to be about managing your cardiovascular health.

Management And Treatment

Effective management and coronary artery calcification treatment involve a combination of lifestyle changes, monitoring, and, when necessary, medical intervention.

• Lifestyle Modifications: This includes adopting a heart-healthy diet, regular physical activity, quitting smoking, and maintaining a healthy weight.
• Medications: Depending on your overall risk, medications such as statins to lower cholesterol, blood pressure medications, or anti-diabetic drugs might be prescribed.
• Regular Monitoring: Keeping track of your heart health through regular follow-up appointments with your doctor is crucial.

How Is Coronary Artery Calcification Treated?

When it comes to coronary artery calcification treatment, the approach can vary based on the severity of the calcification and the overall risk it poses to your health.

• Medications: As part of the treatment strategy, medications that target underlying conditions like high cholesterol, high blood pressure, and diabetes are often used.
• Dietary Changes: Incorporating a diet low in saturated fats and cholesterol, rich in fruits, vegetables, and whole grains can help manage your weight and lower your risk.
• Physical Activity: Engaging in regular physical activity helps improve heart function and is recommended for maintaining good cardiovascular health.
• Surgical Interventions: In severe cases, procedures like angioplasty or coronary artery bypass grafting (CABG) may be necessary to help restore normal blood flow to the heart.

Complications of the Treatment

While treatments for coronary artery calcification are generally safe and effective, like any medical procedure, they come with potential risks. Being familiar with these risks can help you make informed decisions about your healthcare.

Intravascular Lithotripsy Complications May Include:

• Vessel Damage: Although rare, the shock waves used can cause damage to the blood vessel walls.
• Dissection: The treatment might cause a tear in the artery lining, which can be serious.
• Bruising or Bleeding: The site where the catheter is inserted may bruise or bleed more than expected.

Rotational Atherectomy Complications May Include:

• Burr Entrapment: The device used to sand away plaque can become stuck, although this is uncommon.
• Arterial Damage: There's a risk of damaging the artery walls during the procedure.
• Heart Rhythm Irregularities: The procedure may cause temporary heart rhythm issues.

Coronary Angioplasty Complications May Include:

• Restenosis: The treated artery can re-narrow, usually within months of the procedure.
• Blood Clots: Clots can form at the site of the balloon or stent, potentially blocking the artery.
• Artery Collapse: Though very rare, the artery may collapse or severely narrow immediately after the procedure.

How Can I Reduce My Risk?

Reducing your risk of coronary artery calcification (CAC) is primarily about adopting a healthy lifestyle. Focusing on your diet, exercise, and other lifestyle choices can significantly impact your heart health. Eating a balanced diet rich in fruits, vegetables, and whole grains while limiting saturated fats, salt, and sugars is crucial. 

Regular physical activity—aiming for at least 150 minutes of moderate aerobic exercise per week—can also strengthen your heart and improve blood circulation. Additionally, quitting smoking and managing stress effectively are vital steps in reducing your risk.

What Can I Expect If I Have Coronary Artery Calcification?

If you're diagnosed with coronary artery calcification, it's important to understand the potential progression and management of the condition.

• Monitoring: Regular check-ups will be necessary to monitor the progression of calcification.
• Symptom Management: You might experience symptoms such as chest pain or breathlessness, which will require specific management strategies.
