“…But it might not directly affect the results given that a previous study conducted on healthy subjects showed that segmental variation in CCA CirS was not significant. 32 Second, hemodynamic deterioration during grafting may also be a consequence of regional ischemia imposed by transient coronary hemostasis, which could confound the observed results. The influence of ischemic insult on the degree of hemodynamic deterioration, however, is usually subclinical and difficult to assess separately.…”

“…In agreement with previous studies,15, 16 CAAS measurement using 2D‐ST echocardiography in the present study demonstrated the heterogeneous motion pattern and local variations in compliance of different segments of the ascending aortic wall (Figure 1B and 1C). According to previous investigators,14, 15 we divided the ascending aortic wall into 6 equally sized segments. A global CAAS was calculated as the mean value of peak CAAS of the 6 segments.…”

“…A global circumferential ascending aortic strain (CAAS) was calculated as the mean value of peak CAAS of the 6 segments. A corrected CAAS was calculated as the global CAAS/pulse pressure, according to Yuda et al 14.

BackgroundArterial stiffening and atherosclerosis tend to coexist. Strain imaging, using a 2‐dimensional speckle tracking (2D‐ST) method, has been used for arterial stiffness assessment and early identification of atherosclerosis. We investigated whether the ascending aortic strain assessed by 2D‐ST echocardiography at rest can predict the presence of coronary artery disease (CAD).Methods and ResultsTwo hundred seventy‐one consecutive patients with suspected stable angina pectoris sequentially underwent exercise treadmill testing, 2‐dimensional echocardiography, M‐mode echocardiography, 2D‐ST echocardiography, and coronary angiography. Circumferential ascending aortic strain (CAAS) and radial ascending aortic strain were assessed by 2D‐ST echocardiography. Ninety‐two patients with coronary lumen area stenosis ≥70% were categorized as having significant CAD. Global CAAS was significantly lower in patients with significant CAD (7.41±2.30% versus 11.54±4.03%; P<0.001) and remained an independent predictor of significant CAD (odds ratio, 0.64 [0.54–0.75]; P<0.001) after multivariate regression. Based on the receiver operating characteristic curve for diagnosing significant CAD, the optimal cut‐off value of global CAAS was ≤9.22% (sensitivity, 86%; specificity, 70%; area under curve=0.82; P<0.001). Global CAAS decreased with increasing severity of CAD and was significantly associated with 3‐vessel disease (odds ratio, 0.58 [0.42–0.79]; P<0.001). Diagnostics for significant CAD were remarkably better for global CAAS combined with exercise treadmill testing than for exercise treadmill testing alone (area under curve=0.88 versus 0.78; P<0.001).ConclusionsGlobal CAAS assessed by 2D‐ST echocardiography at rest was able to predict the presence of significant CAD and identify multivessel disease. In addition, global CAAS combined with exercise treadmill testing remarkably improved the diagnostics for significant CAD.

“…The initial systolic frame generally served as the frame of interest, to include maximal aortic wall expansion and recoil. As in other instances [10,22], aortic wall was divided into six equidistant regions, all similar in size. In each region, numeric expressions of each 2D-ST variable represented mean values calculated from all points in arterial segments.…”

Evaluation of vascular mechanics through twodimensional speckle-tracking (2D-ST) echocardiography is a feasible and accurate approach for assessing vascular stiffening. Degenerative aortic stenosis (AS) is currently considered a systemic vascular disease where rigidity of arterial walls increases. To assess the circumferential ascending aorta strain rate (CAASR) in thoracic aortas of patients with AS, applying 2D-ST technology. 45 patients with indexed aortic valve areas (iAVA) B0.85 cm 2 /m 2 were studied. Global CAASR served to assess vascular deformation. Clinical, echocardiographic, and non-invasive hemodynamic data were collected. A follow up (955 days) was also performed. Average age of the cohort was 76. ± 10.3 years, with gender balance. Mean iAVA was 0.43 ± 0.15 cm 2 /m 2 . Waveforms adequate for determining CAASR were found in 246 (91 %) of the 270 aortic segments evaluated, for a mean global CAASR of 0.74 ± 0.26 s -1 . Both intra-and inter-observer variability of global CAASR were deemed appropriate. CAASR correlated significantly with age (r = -0.49, p \ 0.01), the stiffness index (r = -0.59, p \ 0.01), systemic arterial compliance and total vascular resistance. There was a significant positive correlation between CAASR, body surface area (BSA), iAVA, and a negative relationship with valvulo-arterial impedance and E/e' ratio (r = -0.37, p = 0.01). The stiffness index was (b = -0.41, p \ 0.01) independently associated with CAASR, in a model adjusted for age, BSA, iAVA and E/e'. Patients with a baseline CAASR B0.66 s -1 had a worse long-term outcome (survival 52.4 vs. 83.3 %, Log Rank p = 0.04). CAASR is a promising echocardiographic tool for studying the vascular loading component of patients with AS.

Abstract: 2DS in the CCAs is simply and quickly performed with high feasibility and excellent reproducibility. In healthy subjects, age and pulse pressure are the most important determinants of mean CAS.
