ABSTRACT

Introduction: The Computerized Coronary angiotomography (CACAT) has been used as a method for the non-invasive visualization of the coronary arteries. CACAT allows the obtaining of images of the coronary arteries and the possible detection of associated illnesses being integrated to the diagnostic resources of the coronariopathy.
Objective: To evaluate the accuracy and soundness of CACAT in comparison with the standard of gold, the Coronary angiography(CAG), for the detection of coronary artery disease (EAC) and to establish it as a reliable study.
Results: 36 patients were included (30 men, 83% and 6 women, 17% with an average age ranging 56 ± 14 years old) with indication to carry out a diagnostic and/or therapeutic CAG in those where 180 vessels were valued. By means of the CAG, 151 vessels (83.88%) were found without obstructive lesions, 25 vessels (13.88%) had an occlusion bigger than 50% and four vessels (2.22%) had affection smaller than 50%. Through CACAT of the 180 vessels under study, 134 vessels (74.44%) were found without obstructive lesions, 36 vessels (20%) had a lesion bigger than 50%, and 10 vessels (5.55%) had affection smaller than 50%. Of a total of 25 (13.88%) significant arterial stenosis detected by CAG, the most, 28% was in the right coronary artery, 24% in the circumflex one, 24% in the anterior descending one, 16% in the left trunk of the coronary artery and only 8% in some of the diagonal arteries. Of the 25 stenosis, 23 (92%) were detected by CACAT. The sensibility and specificity values, the general predictive positive value and predictive negative value of the CACAT with respect to the CAG were 94.44%, 83.33%, 85.00% and 93.75%, respectively.
Conclusion: CACAT provides a high accuracy for the non invasive detection of coronary arterial disease and should be included in the clinical routine examination of said pathology.
