Calcium Score Test: A Key Check for Heart Health

Introduction

The coronary artery calcium (CAC) score is a specialized test that helps assess the risk of heart disease by detecting calcium buildup in the coronary arteries. This buildup, known as calcification , is an early indicator of atherosclerosis, a condition where arteries harden and narrow due to plaque accumulation.

Why is it Important?

Calcified plaques in the arteries increase the risk of heart attacks and other cardiovascular events . The test allows doctors to:

  • Detect hidden heart disease in seemingly healthy individuals.
  • Estimate the risk of future heart attacks.
  • Make informed treatment decisions (e.g., lifestyle changes, cholesterol medications, or aspirin therapy).

Who Should Get Tested?

A calcium score test is typically recommended for patients who:

  • Are 40 years or older with moderate heart disease risk factors.
  • Have a family history of early heart disease.
  • Have high cholesterol, high blood pressure, diabetes, or smoke.
  • Are uncertain about starting preventive therapies (like statins).

How is the Test Performed?

The test is a non-invasive CT scan that takes images of the heart and measures calcium deposits in the arteries. The scoring system is as follows:

  • 0: No calcification, low heart disease risk.
  • 1-100: Mild calcification, moderate risk.
  • 101-400: Moderate-to-high risk; additional preventive measures needed.
  • 400+: High risk! Immediate medical intervention may be required.

What If My Score is High?

A high calcium score means your risk of heart disease is elevated, but it does not necessarily indicate a heart attack is imminent. Treatment may include:

  • Strict blood pressure and cholesterol control.
  • A heart-healthy diet (rich in fruits, vegetables, whole grains, and lean protein).
  • Regular exercise.
  • Smoking cessation and stress management.

Conclusion

The calcium score test is a valuable tool for detecting early heart disease before symptoms appear. If you are at risk, talk to your doctor about the possibility of undergoing this simple, painless test to protect your heart health.
