Table 1. The first Rumberger guideline based on Agatston score using Electron Beam Computed Tomography (EBCT) ( 47 ) .

Calcium Score	Plaque Burden	Clinical Interpretation
0	None	Very low risk of cardiovascular disease
		Likelihood of coronary artery disease presence <5%
		Negative examination
1-10	Minimal	Significant coronary artery disease very unlikely
11-100	Mild	Likely mild or minimal coronary stenosis
101-400	Moderate	Moderate non-obstructive coronary artery disease highly likely
Over 400	Extensive	High likelihood of at least one significant coronary stenosis (> 50% diameter)
