Introduction: Left Main Coronary Artry Disease (LMCA) is a major risk factor for mortality and morbidity. Ct Angiography is a non-invasive screening method for detecting these lesions. The aim of this study was to compare the results of CT Angiography with Conventional Angiography in detecting Left Main, LAD, and LCX lesions, and also the relationship between background variables and diagnostic testing.
Materials and Methods: This retrospective study was conducted in 2018 at Tabriz University of Medical Sciences. Information was collected from patients undergoing CT Angiography and Conventional Angiography. Data were analyzed using SPSS software in order to determine the relation.
Results: None of the variables in the study had a significant relationship with the results of diagnostic tests. The sensitivity and specificity for LAD was 0.40 and 0.23, and 0.53 and 0.21 for LCX, respectively.
Conclusion: The results of this study indicate that there is no relationship between the background variables and the results of diagnostic tests.
