Puntuación de calcio en arterias coronarias y presencia de estenosis angiográficamente significativas Calcium scoring in coronary arteries and presence of angiographically significant stenosis

La presencia de calcio en las arterias coronarias es patognomónica de aterosclerosis. Agatston diseñó un método para cuantificar el puntaje de calcio coronario mediante la tomografía para determinar la asociación entre el grado de calcificación en las arterias coronarias determinado por tomografía de 64 cortes y la presencia de estenosis coronarias significativas (ECS) diagnosticadas por coronariografía invasiva (CI). Se estudiaron 153 pacientes, los cuales estaban programados para CI. Previo a la CI se les cuantificó el puntaje de calcio por arteria y por paciente. El 91,7 % de los pacientes con puntaje &#8804; 10 UA (unidades Agatston) no presentó ECS contra 8,3 % con puntaje &#8805; 401 UA (p 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
