Abstract Background Two-dimensional speckle-tracking echocardiography (STE) may help detect coronary artery disease (CAD) when combined with dobutamine stress echocardiography. However, few studies have explored STE with exercise stress echocardiography (ESE). We aimed to evaluate the feasibility, reliability, and incremental value of STE combined with treadmill ESE compared to treadmill ESE alone to detect CAD. Methods We conducted a case–control study of all consecutive patients with abnormal ESE in 2018–2020 who subsequently underwent coronary angiography within a six-month interval. We 1:1 propensity score-matched these patients to those with a normal ESE. Two blinded operators generated a 17-segment bull's-eye map of longitudinal strain (LS). We utilized the mean differences between stress and baseline LS values in segments 13–17, segment 17, and segments 15–16 to create receiver operator curves for the overall examination, the left anterior descending artery (LAD), and the non-LAD territories, respectively. Results We excluded 61 STEs from 201 (30.3%) eligible ESEs; 47 (23.4%) because of suboptimal image quality and 14 (7.0%) because of excessive heart rate variability precluding the calculation of a bull's-eye map. After matching, a total of 102 patients were included (51 patients in each group). In the group with abnormal ESE patients (mean age 66.4 years, 39.2% female), 64.7% had significant CAD (> 70% stenosis) at coronary angiogram. In the group with normal ESE patients (mean age 65.1 years, 35.3% female), 3.9% were diagnosed with a new significant coronary stenosis within one year. The intra-class correlation for global LS was 0.87 at rest and 0.92 at stress, and 0.84 at rest, and 0.89 at stress for the apical segments. The diagnostic accuracy of combining ESE and STE was superior to visual assessment alone for the overall examination (area under the curve (AUC) = 0.89 vs. 0.84, p = 0.025), the non-LAD territory (AUC = 0.83 vs. 0.70, p = 0.006), but not the LAD territory (AUC = 0.79 vs. 0.73, p = 0.11). Conclusions Two-dimensional speckle-tracking combined with treadmill ESE is relatively feasible, reliable, and may provide incremental diagnostic value for the detection and localization of significant CAD.

Present Pilot Study

Introduction: Cardiovascular diseases have been identified as a major cause of mortality and morbidity in Borneo orangutans (Pongo pygmaeus pygmaeus). Transthoracic echocardiography is usually performed under anesthesia in great apes, which may be stressful and risky in cardiac animals. The aim of the present pilot study was hence to develop a quick and non-stressful echocardiographic method (i.e., the COOLEST method) in awake Borneo orangutans (CardiOvascular examination in awake Orangutans: Low-stress Echocardiography including Speckle Tracking imaging) and assess the variability of corresponding variables.Materials and Methods: Four adult Borneo orangutans trained to present their chest to the trainers were involved. A total of 96 TTE examinations were performed on 4 different days by a trained observer examining each orangutans 6 times per day. Each examination included four two-dimensional views, with offline assessment of 28 variables (i.e., two-dimensional (n=12), M-mode and anatomic M-mode (n=6), Doppler (n=7), and speckle tracking imaging (n=3)), representing a total of 2,688 measurements. A general linear model was used to determine the within-day and between-day coefficients of variation.Results: Mean±SD (minimum-maximum) images acquisition duration was 3.8±1.6  minutes (1.3-6.3). All within-day and between-day coefficients of variation but one (n=55/56, 98%) were <15%, and most (51/56, 91%) were <10% including those of speckle tracking  systolic strain variables (2.7% to 5.4%).Discussion: Heart morphology as well as global and regional myocardial function can be assessed in awake orangutans with good to excellent repeatability and reproducibility.Conclusions: This non-stressful method may be used for longitudinal cardiac follow-up in awake orangutans.

  Background. Speckle tracking echocardiography (STE) provides valuable data on myocardial function. STE during dobutamine stress echocardiography (DSE) allows reliable myocardial ischemia diagnosis. Aim. To evaluate STE during DSE in patients with coronary artery disease (CAD) after acute coronary syndrome (ACS) and its accuracy in ischemia diagnosis, assessment of myocardial viability and coronary reserve. Methods. We examined 58 patients (55 [94,8 %] men and 3 [5,2 %] women) men) with CAD after ACS admitted to our Institute for defining indications for coronary interventions. All the patients underwent DSE with STE for longitudinal strain quantification. Results. Mean left ventricular ejection fraction (LVEF) was 52.4±5.8%. Significant CAD according to coronary angiography (CAG) prior to DSE was proved in 38 (65.5%) patients. All the patients had a history of ACS up to 12 years before the examination (38 [65.5%] patients after percutaneous coronary intervention (PCI), including 18 [31.0%] primary PCI; 9 [15.5%] patients after coronary artery bypass grafting (CABG); 3 [5.2%] after graft PCI, 1 [1.72%] patient after aortic valve replacement (AVR) with dilated cardiomyopathy (DCM) phenotype). There were no significant complications during DSE: 5 (8.6%) cases of relatively low grade transient arrhythmia with no need for intervention. As per DSE results, we performed 35 (60.3%) revascularization interventions: 31 (58.6%) PCI’s and 4 (6.9%) CABG procedures with good outcomes. It was shown that DSE with STE sensitivity and specificity were 89.7% and 94.7% (AUC 0.92), respectively, with positive and negative predictive values of 97.2% and 81.8%, respectively, with extremely high OR 157.5, p<0.0001. Combined quantification of ΔGLS and ΔWMSI showed insignificantly lower sensitivity (86.3% [p=0.57]) and specificity (87.8% [p=0.19]) vs. integral semiquantitative ischemia markers with significantly lower overall method accuracy (AUC 0.79, p=0.047). Conclusions. DSE with STE as a visualization method is a safe and optimal method for ischemia diagnosis, as well as for myocardial viability and coronary reserve assessment in patients with CAD after ACS with the aim of risk stratification and defining indications for interventions and myocardial revascularization.
