%X La coronariograf赤a invasiva (CI) constituye el patr車n de referencia para el estudio de las arterias coronarias. Se ha planteado que la tomograf赤a computarizada de m迆ltiples cortes (TCMC) puede evitar la CI. Se estudiaron 62 pacientes, 50 del sexo masculino, edad media 56 ㊣ 8 a os para evaluar la precisi車n diagn車stica de la TCMC de 64 cortes en la detecci車n de estenosis coronarias significativas (ECS), compar芍ndola con la CI. Se les realiz車 la CI por presentar ECS o persistencia de los s赤ntomas. Se determin車 sensibilidad (S), especificidad (E), valor predictivo positivo (VPP), valor predictivo negativo (VPN) y precisi車n predictiva (PP) por pacientes y por arterias. La S, la E, el VPP, el VPN y la PP fueron 96,4; 91,2; 87; 96,8 y 93,5 %, respectivamente, por pacientes, y 95,7; 97; 88,2; 98,9 y 96,7 %, respectivamente, por arterias. Se concluy車 que la TCMC puede sustituir la CI en pacientes seleccionados. Invasive coronariography (IC) is the reference pattern for the study of coronary arteries. It has been stated that multiple slice computed tomography (MSCT) may avoid IC. 62 patients, 50 of whom were males, with mean age 56 ㊣ 8, were studied to evaluate the diagnostic accuracy of the 64-slice MSCT in the detection of significant coronary stenoses (SCS), comparing it with IC. IC was performed due to the presence of SCS or persistence of the symptoms. Sensitivity (S), specificity (E), positive predictive value (PPV), negative predictive value (NPV) and predictive accuracy (PA) were determined by patients and arteries. S, E, PPV, NPV and PA were 96.4; 91.2; 87; 96.8 and 93.5 % per patient, respectively; whereas they were 95.7; 97; 88.2; 98.9 and 96.7 % by artery, respectively. It was concluded that MSCT may replace IC in selected patients.
