[Relationship between computed tomography coronary angiography and adenosine stress myocardial perfusion imaging for the assessment of coronary artery disease].
OBJECTIVE
To compare the accuracy of computed tomography coronary angiography (CTCA) and adenosine stress myocardial perfusion imaging in the diagnosis of coronary artery disease (CAD) and discuss their relationship.


METHODS
Fifty-six patients, suspected or diagnosed as CAD, were performed with CTCA, MPI and coronary angiography (CAG) within 3 weeks. They were divided into 3 groups: no CAD, no obstructive CAD (coronary artery stenosis < 70%) and obstructive CAD (coronary artery stenosis > or = 70%).


RESULTS
5 patients were diagnosed as no CAD. 19 patients were diagnosed as no obstructive CAD and 32 patients were diagnosed as obstructive CAD by CTCA. While adenosine stress MPI suggested 26 patients normal, 18 patients had IPD and 29 patients had RPD. The sensibility, specificity, positive predictive value (PPV) and negative predictive value (NPV) of CTCA were 100%, 55.6%, 92.2% and 100% versus 78.6%, 71.4%, 73.3% and 76.9% respectively for adenosine stress MPI.


CONCLUSIONS
CTCA and adenosine stress MPI provide different and complementary information on CAD, anatomical versus functional. As compared with CAG, CTCA has a high accuracy of detecting CAD.
