Understanding LAD Calcium Score: Normal vs Optimal Ranges

?What is LAD Calcium Score?

The LAD calcium score measures the amount of calcified plaque in the left anterior descending coronary artery using non-contrast CT imaging. It quantifies coronary artery disease burden in this specific vessel, which supplies blood to the front and left side of the heart. Higher scores indicate greater calcification and plaque burden.

!Why It Matters

The LAD calcium score can help assess cardiovascular risk and the presence of subclinical atherosclerosis before symptoms develop. An elevated score may suggest increased risk for coronary events, though a single marker does not diagnose disease. This measurement helps guide preventive strategies and treatment decisions.

Reference Ranges

Lab normal ranges may vary between laboratories. Optimal and longevity targets are based on research literature and should be interpreted with your physician.

Symptoms of Imbalance

• Chest pain or angina
• Shortness of breath during exertion
• Fatigue with physical activity
• Heart palpitations
• No symptoms (often detected incidentally)

How to Improve Your Levels

• 1Adopt a heart-healthy diet low in saturated fats and sodium
• 2Engage in regular aerobic exercise (150 minutes per week)
• 3Maintain healthy blood pressure and cholesterol levels
• 4Quit smoking and avoid secondhand smoke exposure
• 5Manage stress through meditation or relaxation techniques
• 6Maintain a healthy weight and reduce inflammation markers

When to Test

CAC scoring is typically considered for asymptomatic adults aged 40–75 with intermediate cardiovascular risk, or those with a family history of early coronary disease. Individuals with diabetes, hypertension, or elevated lipids may benefit from screening.
