Understanding OM2 Calcium Agatston: Normal vs Optimal Ranges
Also known as: agatston score, coronary artery calcium score, cac score, om2 cac
?What is OM2 Calcium Agatston?
The OM2 Calcium Agatston test quantifies calcified plaque in the coronary arteries using non-contrast CT imaging, expressed in Agatston units. Higher scores indicate greater calcium burden and may suggest increased atherosclerotic disease burden. This test is used to assess cardiovascular risk stratification in asymptomatic individuals.
!Why It Matters
Coronary artery calcium scoring can provide additional risk information beyond traditional risk factors and may help guide preventive therapy decisions. A higher Agatston score may suggest greater atherosclerotic burden and could be associated with elevated risk of future cardiovascular events, though a single test does not establish diagnosis.
Reference Ranges
| Range Type | Min | Max | Unit | Note |
|---|---|---|---|---|
| Lab Normal | 0 | — | Agatston Units | Standard lab reference range |
| Optimal | 0 | 10 | Agatston Units | Evidence-based optimal range for health |
| Longevity Target | 0 | 10 | Agatston Units | Per longevity medicine research (Attia et al.) |
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
- No symptoms (asymptomatic screening test)
- Family history of premature heart disease
- Chest discomfort or angina
- Shortness of breath during exertion
- History of hypertension or diabetes
How to Improve Your Levels
- 1Maintain a heart-healthy diet low in saturated fat and processed foods
- 2Engage in regular aerobic exercise (150 minutes per week)
- 3Manage blood pressure and cholesterol levels through medication and lifestyle
- 4Quit smoking if applicable
- 5Reduce stress through meditation or mindfulness practices
- 6Maintain a healthy weight and manage metabolic risk factors
When to Test
Typically recommended for asymptomatic adults aged 40–75 with intermediate cardiovascular risk, or those with risk factors such as family history, diabetes, or hypertension who require risk stratification.
