Two-dimensional speckle tracking for the assessment of coronary artery disease during dobutamine stress echo: clinical tool or merely research method



Two-dimensional speckle tracking provides valuable information for regional wall motion abnormalities. The purpose of this study was to determine the diagnostic value of left ventricular longitudinal strain and torsion to diagnose coronary artery disease during dobutamine stress echocardiography.


We studied 100 patients (mean age 60.8 ± 10.7 years, 72 male) with known or suspected coronary artery disease, excluding those with prior history of transmural infraction. All of them underwent dobutamine stress echo and coronary angiography within one month. Wall-motion score index, left ventricular global longitudinal strain and torsion were measured at rest and peak stress. Additionally, the respective differences between rest and stress were also calculated. Optimal cut-offs were derived from receiver operating characteristic curves for strain and torsion values.


Mean left ventricular ejection fraction was 55 ± 5.4 %. Coronary angiography revealed significant lesions in 67 patients. Values regarding sensitivity, and specificity for wall motion score index difference were 78 % and 88 % respectively (area under curve 0.84). Global longitudinal strain difference (median 0.5 %) illustrated 81 % sensitivity and 72 % specificity for disease detection (area under curve 0.80, cut-off value ≤0 %). The respective values for torsion difference (median 4.7°) were 81 % and 82 % (area under curve 0.76, cut-off value ≤6.5°). Combination of wall motion score index difference and torsion difference for disease detection showed 91 % sensitivity and 79 % specificity (area under curve 0.85).


The implementation of speckle tracking during dobutamine stress echo could serve as an adjunct method for coronary artery disease assessment, providing quantitative diagnostic information.

Peer Review reports


Timely and prompt detection of coronary artery disease (CAD) is of paramount importance for patient management in daily clinical practice. Dobutamine stress echocardiography (DSE) is a non-invasive method with established diagnostic accuracy. Still, it remains subjective, mainly because of its dependence from operator experience on image acquisition and interpretation [1, 2].

Speckle tracking echocardiography is a novel method for the assessment of global and regional left ventricular myocardial function. It provides valuable insights to myocardial deformation by quantifying strain and torsion with the inherent advantage of being angle-independent [3, 4]. From the clinical perspective, it has already been used for assessing different myocardial and systemic diseases, where it can predict probable sub-clinical cardiac disorder earlier in the course of the disease process when conventional 2D echocardiography appears to be normal [59].

Speckle tracking derivatives are less susceptible to translational motion and tethering, which lead to erroneous qualitative evaluation of stress echo images. So far few studies have been published exploring the implementation and clinical utility of speckle tracking imaging during DSE [1013]. The aim of the current study was to assess the feasibility of speckle tracking during DSE and evaluate the diagnostic accuracy of 2D global longitudinal strain and torsion, along with its additive role over wall motion abnormalities interpretation for the diagnosis of CAD.


Study population

We studied 114 consecutive patients with known or suspected coronary artery disease who were referred to our tertiary center for evaluation of myocardial ischemia or coronary angiography. Fourteen patients were rejected due to poor acoustic window, unsuitable for speckle tracking echo. Eventually 100 patients were included in the study. All of them underwent DSE and coronary angiography within one month. Patients with depressed left ventricular function (EF < 45 % at rest), significant valvular heart disease, left bundle branch block on ECG, pacemaker and history of coronary artery bypass surgery were also excluded. The study protocol was approved by the ethics committee of the Hippokration Hospital of Athens and all patients gave written informed consent.

Image acquisition

All studies were performed with an iE33 ultrasound machine (Philips Medical Systems, USA), equipped with the 2.5 MHz S5-1 transducer. Images were obtained with patients being positioned in the left lateral decubitus position, in the parasternal short axis (mitral leaflet, annular and apex level) and apical 4-, 3- and 2-chamber views at rest and peak dobutamine infusion. Two-dimensional grayscale images were obtained at a frame rate of 70–80 Hz in order to be optimal for speckle tracking, during three cardiac cycles and were then digitally stored for off-line analysis. Quantitative measurements of longitudinal strain and torsion were made using the QLAB 9.0 software package.

Dobutamine stress echo

Dobutamine stress echo was performed using a standard protocol [14]. An intravenous line was placed and dobutamine was infused in four 3-min stages: 10-20-30-40 μg/kg/min. Atropine was given at the end of 12-min period, as required (at a dose of 0.2-1 mg) to achieve the age-adjusted target heart rate [0.9 x (220-age)], unless contraindicated. A short-acting beta-blocker (esmolol 20–40 mg) was administered upon test completion to all patients (except those with a known history of severe bronchospasm) in order to accelerate normalization of the heart rate. All patients were asked to withdraw b-blockers for at least 48 h prior testing.

The stress protocol was terminated if : (1) the age-adjusted target heart rate was achieved; (2) four or more contiguous segments showed signs of ischemia; (3) the patient reported intense chest pain; (4) the electrocardiogram showed VT, ventricular bigeminy or trigeminy, or multiform premature ventricular complexes; (5) if any other grade > 2 adverse event appeared.

Wall motion was assessed by an expert observer. The 17-segment model of the left ventricle was used [15]. Myocardial segments were graded according to their wall motion at baseline and at each stage of the protocol, as normokinetic (grade 0), hypokinetic (grade 1), akinetic (grade 2) or dyskinetic (grade 3). Any deterioration by one grade or more, from baseline to peak stress, in two or more contiguous segments was considered indicative of ischemia. Wall motion score index (WMSI) was calculated at rest and peak stress and then the difference (value at stress minus value at rest, WMSIΔ) was derived.

Speckle tracking echocardiography

Longitudinal strain and torsion measurements with the implementation of 2D speckle tracking were performed as previously described [5]. End-systole has been identified as corresponding to the aortic valve closure measured by pulsed-Doppler. The operator traced the endocardial border on an end-diastolic frame and the software automatically tracked the border on the subsequent frames. Adequate tracking can then be verified in real-time and corrected if deemed necessary by adjusting the region of interest or manually correcting the border to ensure optimal tracking. After the tracking process is completed myocardial deformation is plotted in time versus strain graphs, where it is possible to identify the different phases of cardiac cycle (Fig. 1).

To assess left ventricle rotation, six tracking points were placed on the myocardium, avoiding the pericardium on an end-diastolic frame in each parasternal short-axis image as determined automatically by the software algorithm. Counterclockwise rotation, as viewed from the apex, was expressed as a positive value; clockwise rotation was expressed as a negative value. Analysis was performed to evaluate the peak apical rotation during the ejection phase, the basal rotation at a time isochronous with that of peak apical rotation during the ejection phase and the net instantaneous torsion of the left ventricle, which was calculated as peak apical minus the basal rotation at a time isochronous with peak apical rotation.

Anterior and posterior circulation was evaluated separately as proposed by Geleijnse et al. [14]. For anterior circulation the mean value of strain was calculated using all the segments which are supplied from the LAD, which are the anterior, anteroseptal, apical and midseptal segments. Similarly for posterior circulation the mean value of strain was calculated of all segments which are supplied from the RCA and LCX taken together, which are the basal, and mid inferior, basal inferoseptum, basal and mid lateral and basal and mid posterior. Finally the change (Δ-delta) in longitudinal strain and torsion (value at peak stress minus value at rest) was estimated.

Coronary angiography

All patients underwent coronary angiography within one month according to the Judkins technique. All images were evaluated by an experienced operator, and significant coronary artery disease was defined as >70 % luminar diameter stenosis.

Statistical analysis

Data analysis was performed using the SPSS 20.0 statistical package for Windows (SPSS Inc., Chicago). Continuous variables were presented as mean ± SD, whereas categorical variables were expressed as percentages. The chi-square test was used to compare categorical variables. Independent t-tests were used for comparison of matched segments in patients with and without CAD. Receiver operating characteristics curves (ROC) for each of the strain and torsion parameters was calculated and the optimal stain and torsion cutoff values for predicting CAD were then determined. In all cases, a p-value < 0.05, was regarded as statistically significant. For global intra- and interobserver variability, 10 patients were selected at random, and measurements were repeated by the same observer on the same echocardiographic images 2 weeks apart and by another independent observer. The inter-observer variability was assessed using a two-way mixed, absolute agreement, single measures intra-class correlation.


Patient demographic data and hemodynamics are illustrated in detail in Tables 1 and 2. Mean age was 60.8 ± 10.7 years old (72 male), with mean left ventricular EF 55 ± 5.5 %. Coronary angiography revealed significant CAD in 67 patients. Of them, 46 had single-vessel disease while the rest of the study population had multi-vessel disease.

Table 2 Patient hemodynamics at rest and stress

We analyzed 3400 segments both in rest and stress. A total of 425 of the analyzed myocardial segments were rejected due to poor tracking. More specific, in rest the feasibility rates were 90 % (170 segments could not be analyzed), whereas in peak stress the feasibility rates were 85 % (255 segments could not be analyzed). In addition, we sought to determine inter and intra-observer variability at rest and peak stress. The correlation coefficient for the same observer at rest was 0.95 for 2D strain and 0.91 for torsion, while between the 2 observers were 0.91 and 0.89 respectively. At peak stress, the respective values for a single observer were 0.87 for GLS and 0.82 for torsion, while between two observes were 0.83 and 0.80.

Wall-motion score index at rest was 1.06 ± 0.99, while at stress was 1.20 ± 0.20. The difference in values of WMSI between stress and rest (WMSIΔ), exhibited 78 % sensitivity, 88 % specificity (AUC 0.84, cut-off value >0). Speckle tracking echo measurements are shown in Table 3. In specific, reduced GLSΔ values were reported in patients with CAD as compared to those without (−2.23 ± 3.36 % vs. 1.56 ± 3.15 % respectively, p < 0.005). Similarly, torsionΔ values were significantly reduced in ischemic patients as compared to normal persons (−2.42 ± 13.96° vs.9.50 ± 10.46° respectively, p < 0.005) (Fig. 2). Global longitudinal strain delta (Δ) illustrated 81 % sensitivity and 72 % specificity for the detection of CAD (AUC 0.80, cut-off value ≤0 %). The respective values for torsion delta (Δ) were 81 and 82 % (AUC 0.76, cut-off value ≤6.46°) (Fig. 3).

The combination of GLSΔ and ΤorsionΔ for the detection of CAD showed 97 % sensitivity and 52 % specificity (AUC 0.77). The diagnostic value of the combined GLSΔ and ΤorsionΔ assessment was more sensitive as compared to wall-motion assessment alone (p < 0.05). The combined assessment of GLSΔ and WMSIΔ revealed 87 % sensitivity and 73 % specificity (AUC 0.80), not statistically significant different than either indice alone. On the other hand the combined assessment of TorsionΔ and WMSIΔ revealed 91 % sensitivity and 79 % specificity (AUC 0.85), higher than either indice separately (without the differences being statistically significant though). Comparison of AUC is depicted in detail in Table 4.

In addition, we reclassified our analysis according to coronary vessel territory. Longitudinal strain parameters are depicted in Table 5. It is shown that longitudinal strain delta(Δ) values regarding patients with LAD disease are reduced in comparison to those with normal LAD (−5.46 ± 5.27 % vs. 1.76 ± 3.77 %, p < 0.001). Again, for posterior circulation strain values were changed in similar fashion (−2.83 ± 5.11 % vs. 2.18 ± 3.95 %, p < 0.001). Area under the curve for LAD detection was 0.87, reporting 94.7 % sensitivity and 62.5 % specificity (cut-off value ≤1.67 %). For posterior circulation AUC was 0.78 (74 % sensitivity, 83 % specificity, cut-off value ≤ −2 %). Changes in torsion values between rest and stress were able to predict LAD disease with 56 % sensitivity and 78 % specificity (AUC 0.65, cut-off value ≤ 10.1°), while for posterior circulation the reported values were 81 and 60 % respectively (AUC 0.62, cut-off value ≤ 5.9°) (Fig. 3).

The findings of our study demonstrate that the measurement of both 2D-longitudinal peak systolic strain and LV torsion during dobutamine stress echocardiography is feasible and provide quantifiable information for the identification of myocardial ischemia in patients without previous MI, with good overall reproducibility. It is now well established that speckle tracking is feasible during DSE. Our feasibility and reproducibility rates match those reported by other authors [16, 17]. Initial studies have shown that two dimensional (2D) strain measurements can reveal wall motion abnormalities even at rest in high risk patients [1012].

We found that the regional strain for anterior and posterior circulation revealed statistically significant difference between the two groups at rest. According to Choi et al., patients with left main or three-vessel CAD without regional wall motion abnormalities have significantly lower peak systolic longitudinal strain at rest, reflecting the early impairment of longitudinal strain in the ischemic cascade [10]. Furthermore, 2D strain can be calculated at any stage of DSE giving significant information for the presence of ischemia, even at low dose stage [1820]. Recently, it was shown that the detection of severe CAD (three-vessel disease) can been accomplished during the early stages of DSE before the occurrence of regional wall motion abnormalities, as the longitudinal strain is lower in patients with CAD [21].

Another study has revealed that longitudinal strain had higher diagnostic accuracy than circumferential and radial strains and reported similar diagnostic accuracy as expert wall motion analysis for the detection of CAD [22]. Considering this, we used only the longitudinal strain as the best parameter to detect ischemia. Moreover ischemic changes primarily affect long-axis function, as the subendocardial myocardial fibers, which are mainly longitudinal oriented, are more susceptible to ischemia.

We demonstrated that the combined assessment of GLSΔ and WMSIΔ, as well as Torsion Δ and WMSIΔ, failed to show better diagnostic ability during DSE. Perhaps, this could attributed to the lower feasibility rates at peak stress, 255 segments could not be analyzed. Still, it offers enhanced sensitivity than each indice alone, on the expense however of lower specificity, especially in the combination of GLSΔ and WMISΔ. The enhanced sensitivity could prove valuable in clinical practice when assessing intermediate to high risk patients, in order to minimize false negative rates, which could have a negative impact on their outcomes. Similar results have been highlighted by Arnold et al., who found that the combination of GLS and WMSI offers enhanced diagnostic ability [22]. We took this information one step further by exploring the additive value of torsion.

The assessment of the LV torsion by speckle tracking echocardiography is feasible, as initial studies have shown [2325], but very few of them have incorporated the LV torsion measurement during DSE [26, 27]. Torsion can be a marker of the global systolic myocardial performance, directly related to fiber architecture and the contractility of the myocardium. In our study, we noticed reduction of the LV torsion at peak stress in patients with CAD. On the contrary, patients without CAD had a significant augmentation of the LV torsion, which is evidence of the increased contractility of the LV at dobutamine peak dose. Interestingly, LV torsion was more sensitive in detecting posterior circulation disease, perhaps due to the fact that the apical rotation is less pronounced than basal rotation. This was also previously shown by Knudtson et al. [28], who demonstrated reduction in apical LV rotation with balloon occlusion of the LAD. Similar findings of impairment in LV apical rotation and torsion in response to coronary occlusion have been reported in the anaesthetized dogs [29].

In addition, we analyzed the change in the regional strain according to the coronary arteries’ supply territory and could assess anterior or posterior circulation involvement separately. In our study, 2D-strain exhibited superior diagnostic efficiency for the evaluation of anterior coronary circulation, as compared to posterior circulation. Our results seem to verify those reported by Hanekom et al. [13]. The lower diagnostic reported measures in the posterior circulation could be attributed to tracking problems in the posterolateral segments. Moreover, the same group compared the accuracy of the speckle tracking longitudinal strain and the accuracy of the tissue velocity imaging (TVI)-based strain during DSE and showed that they were similar in the anterior, but not in the posterior circulation.


It should be noted though, that there is probable selection bias with regards to participants’ BMI. Obese people were rejected from our study, which in turn could lead to feasibility overestimation. Patients with transmural myocardial infarction have been excluded from this study due to abnormal torsion at rest, which could potentially result into different torsion response during stress echo. Moreover, the aim of the study was to investigate the diagnostic accuracies of strain analyses for detection of significant CAD on angiography and not the assessment of myocardial viabilities and therefore patients with severely depressed resting LV ejection fraction (LVEF ≤40 %) were excluded. Finally, there are certain limitations inherent to the technique of STE, which could reduce the signal-to-noise ratio especially during higher heart rates. Another limitation is that we did not use contrast agents to improve wall motion interpretation. Although this might have increased the diagnostic capability of WMSI, it would also have made speckle tracking imaging impossible.

Clinical perspective

Given that deformation parameters and specifically global longitudinal strain can detect ischemia in an early stage, it could potentially provide better risk stratification for our patients. Furthermore, LV torsion was more sensitive in detecting posterior circulation disease, perhaps due to the fact that the apical rotation is less pronounced than basal rotation. This finding could be translated into clinical efficacy, since the ability of DSE to diagnose posterior circulation disease is somehow obscured by imaging difficulties of this specific region of interest. In addition, novel software algorithms allow for easier, faster and reproducible measurements, transforming speckle tracking into a robust clinical tool in the near future.


In the present study we showed that the measurement of LV torsion and 2D-strain is feasible during DSE. Therefore, both of them might be used as a quantitative tool in combination with wall motion abnormalities for the detection of CAD. In addition, 2D-strain can give quantitative information for segmental ischemia, which comes in accordance with the angiographic findings.
