“…Then, the LCX flow velocities were recorded ( Figure 1C). 11,12 The DDT was estimated from the peak diastolic velocity to the point when the extrapolated line intersected the base line for 3 cardiac cycles, and averaged ( Figure 2). 13 To measure the coronary flow velocity reserve (CFVR), the baseline spectral Doppler signals of coronary flow were recorded at the end of expiration.…”

Background: There are limited data available regarding the use of diastolic deceleration time (DDT) of three major arteries measured by transthoracic echocardiography (TTE) for assessing coronary microvascular damage after acute myocardial infarction (AMI). Therefore, we aimed to compare the DDT of three major arteries using TTE with the transmural extent of infarction (TEI) and infarct size, which were classified using contrast-enhanced magnetic resonance imaging (CE-MRI), in patients with AMI. Methods: The DDT of the culprit coronary artery was measured in 74 patients using TTE and CE-MRI 1 week after the onset of AMI. The TEI was graded based on the transmural extent of the hyper-enhanced tissue (grades 1-4). Results: The assessable rate for the DDT was 95%; individual rates were 100% for the left anterior descending coronary artery, 90% for the left circumflex artery, and 93% for the right coronary artery. The DDT decreased gradually as the TEI grade progressed (P = .021). Infarct size was significantly correlated with the DDT (r = −0.51, P < .0001). Univariate analysis revealed that the left ventricular (LV) end-systolic volume, LV ejection fraction, and DDT were significantly associated with TEI grade 4. After adjustment via multiple logistic regression analysis, the DDT was independently remained. With a cutoff value of 950ms, as determined by the ROC curve, DDT could detect TEI grade 4 with 81.1% sensitivity and 80.1% specificity. Conclusion: The DDT of three major coronary arteries measured by TTE 1 week after the onset of AMI can assess the extent of myocardial damage, which is determined by CE-MRI.

“…A previous report demonstrated that CFVR could detect myocardial ischemia in the three major coronary arteries [18]. In addition, a combined assessment of CFVR and CTA provides physiological information about coronary flow reserve [19]. However, it is sometimes difficult to clearly detect coronary flow in all three major coronary arteries.…”

Computed tomography (CT) has become one of the essential medical tools in the diagnosis of coronary artery disease (CAD).Cardiac CT has been used for anatomical evaluation of stenosis, plaques, and calcification. CT angiography (CTA) is a noninvasive assessment for the presence of coronary stenosis, and is used clinically as a standard modality to diagnose ischemic heart disease (IHD) [1][2][3]. Although anatomical information on the coronary arteries is indispensable for the diagnosis of CAD, an evaluation of myocardial ischemia provides more important prognostic information beyond the severity of organic coronary stenosis. The evolution of myocardial perfusion imaging has increased the value of noninvasive assessment of myocardial ischemia [4][5][6][7]. As an
