Cat.SignificadoCondutaRiscoFonte
0
No identifiable calcium
Agatston score of 0: no identifiable calcified coronary plaque on the gated noncontrast CT (no calcific lesions reaching the detection threshold across the proximal coronary arteries).		With a score of 0 and no other major risk factors, statin therapy is generally not indicated; the finding supports deferring or withholding pharmacologic prevention and reassessing later. (Final decisions follow ASCVD-prevention guidelines.)'No identifiable disease'; extremely low risk of cardiovascular events. A zero score is described as the most powerful negative predictor (the 'power of zero') in asymptomatic patients; the original 1990 cohort reported a negative predictive value of 94-100% for clinical coronary disease across the 40-69y groups.

Severity label, risk interpretation and statin guidance from StatPearls 'Coronary Artery Calcification' (NBK519037), CAC interpretation / clinical-significance and management sections ('0 = No identifiable disease'; 'power of zero'; 'CAC = 0 with no other risk factors: no statin indicated'). NPV figure from Agatston 1990 abstract.
1-99
Mild
Agatston score 1-99: a small amount of calcified coronary plaque (mild calcified plaque burden).		Statin therapy is generally initiated in patients older than ~55 years; in younger patients (<55) statin may be withheld with reassessment in ~3-5 years.'Mild disease' / mild calcified plaque burden, conferring modestly increased cardiovascular risk above a zero score.

100-399
Moderate
Agatston score 100-399: a moderate amount of calcified coronary plaque (moderate calcified plaque burden).		Statin therapy is recommended (CAC over 100 generally warrants statin).'Moderate disease' / moderate calcified plaque burden, with progressively elevated cardiovascular risk relative to lower bands.

>=400
Severe
Agatston score 400 or higher: an extensive amount of calcified coronary plaque (severe calcified plaque burden).		Statin therapy is recommended (score over 100 warrants statin); a score over 400 is widely regarded as severe and may prompt further cardiovascular evaluation.'Severe disease' / extensive calcified plaque burden; a CAC over 400 is associated with worsened clinical outcomes and correlates with advanced/obstructive coronary disease.
