MENDOZA RODRIGUEZ, Vladimir et al. Calcium scoring in coronary arteries and presence of angiographically significant stenosis. Rev cubana med [online]. 2007, vol.46, n.3, pp. 0-0. ISSN 1561-302X.

The presence of calcium in the coronary arteries is pathognomonic of atherosclerosis. Agatston designed a method to quantify the coronary calcium scoring by tomography to determine the association between the degree of calcification in the coronary arteries by 64-slice computed tomography and the presence of significant coronary stenosis (SCS) diagnosed by invasive coronariography (IC). 153 patients that were scheduled for IC were studied. The calcium scoring was quantified by patient and by artery before performing the IC. 91.7 % of the patients with scoring £10 UA (Agatston units) did not present SCS versus 8.3 % with scoring  ³ 401 UA (p<  .0001). 2.4 % with scoring 10 UA in the trunk of the left coronary presented SCS versus 75 % with scoring 401 UA (p < 0.0001). 5.5 % with scoring 10 UA in the anterior descending artery has SCS versus 87.5 % with scoring   401 UA (p < 0.0001). Similar behavior was observed in the rest of the arteries. It was concluded that there was association between the calcium degree scoring in the coronary arteries diagnosed by computed tomography and the presence of SCS diagnosed by IC.
