Introduction: MDCT coronary angiography has been evolving as a noninvasive method for the assessment of coronary artery disease (CAD). More recently, It has been demonstrated that MDCT identifies reduced contrast enhancement in ischemic and/or scarred myocardial segments. Objective: to determine the ability of rest-stress multidetector computed tomography (RS-MDCT) to detect myocardial ischemia and to assess the relationship between MDCT myocardial perfusion abnormalities and coronary artery stenosis. Methods: Forty seven patients underwent stress/rest 99mTc sestamibi SPECT and RS-MDCT, using a 16-row detector scanner (Philips Brilliance-16). Myocardial segments were classified by SPECT as normal, ischemic or scarred. SPECT results were then compared with MDCT regional myocardial contrast enhancement. The results of MDCT coronary angiography were also analyzed in 20 patients who underwent invasive catheterization. Results: The presence of a reduction in contrast enhancement at rest by MDCT identified scar by SPECT with 96% sensitivity and 98% specificity. A stress-induced reduction in contrast enhancement by MDCT identified ischemia by SPECT with 77% sensitivity and 99% specificity. The segment-based sensitivity and specificity for the detection of significant stenosis by MDCT were 92% and 98%, respectively. Conclusion: Our results showed that a rest-dipyridamole stress MDCT protocol can identify the presence of myocardial ischemia as well as the severity of coronary artery stenosis in patients with suspected coronary artery disease.

Abstract Background The aim of this study was to investigate the incremental value of global longitudinal strain (GLS), postsystolic strain index (PSI) and prestretch (PSE) by automated function imaging with respect to wall motion (WM) and coronary flow reserve (CFR) for the diagnosis of significant coronary artery disease (CAD) during dipyridamole stress echocardiography. Methods We retrospectibely enrolled 227 patients with known or suspected CAD, approaching our echo lab to perform a DSE; all patient underwent coronary angiography within 1 month for clinical reasons. Obstructive CAD was defined as the evidence of >70% stenosis during coronary angiogram. Obstructive CAD was detected in 143 (63%) patients, while 84 (37%) had no significant CAD. Global longitudinal strain, PSI and PSE were measured at rest and peak of the stress (after 6 minutes of 0,84mg/kg of dipyridamole infusion). Results Patient with CAD showed a significantly lower GLS at rest (−16.9±4.2 vs −18.6±3.4; p<0.01) and peak (14.9±3.8 vs −21.50±3.3; p<0.01) Figure A; the behavior of GLS was opposite, in patient with CAD showed an increase while in patient without CAD a significant decrease after dipyridamole infusion. There was also a significant difference between groups for Delta PSI (PSIpeak − PSIrest) and Delta PSE (PSEpeak − PSErest), respectively 126±145 vs −40±97, (p<0.01) and 108±163 vs −41±106 (p<0.01) Figure C. ROC analyses produced a statistically valid model: Average GLS at peak (p 0.001; AUC=0.906, cut-off value −18%, sensitivity 83% and specificity 82%); on the basis of these results, we compared WM and myocardial deformation analysis and GLS was superior to CFR LAD, Delta EF, Delta ESV and Delta WMI (Figure B). Conclusions GLS, PSE and PSI show an opposite response to dipyridamole, in patients with CAD in patient without CAD and show much higher sensitivity and specificity compared to the conventional parameters like WMI, EF and CFR in detecting CAD Funding Acknowledgement Type of funding source: None
