“…In the cardiac ‘stress-test’, subjecting the heart to the stress of exercise reveals key diagnostic signatures of heart disease vulnerability that are not evident at rest9. Here we seek to develop an emotional analogue of this ‘stress test’.…”

Response to stress or external threats is a key factor in mood and anxiety disorder aetiology. Current measures of anxious responding to threats are limited because they largely rely on retrospective self-report. Objectively quantifying individual differences in threat response would be a valuable step towards improving our understanding of anxiety disorder vulnerability. Our goal is to therefore develop a reliable, objective, within-subject ‘stress-test’ of anxious responding. To this end, we examined threat-potentiated performance on an inhibitory control task from baseline to 2–4 weeks (n = 50) and again after 5–9 months (n = 22). We also describe single session data for a larger sample (n = 157) to provide better population-level estimates of task performance variance. Replicating previous findings, threat of shock improved distractor accuracy and slowed target reaction time on our task. Critically, both within-subject self-report measures of anxiety (ICC = 0.66) and threat-potentiated task performance (ICC = 0.58) showed clinically useful test-retest reliability. Threat-potentiated task performance may therefore hold promise as a non-subjective measure of individual anxious responding.

“…28 In addition, the increased respiratory rate with exercise makes image acquisition and interpretation difficult. 29 Strain abnormalities are known the same segments show reduced LS in patients without significant ischemia. 31,32 Aforementioned along with wide dispersion in specificity (55%-100% for visual assessment of WM and 49%-93% for LS imaging) might have resulted in a similar specificity in our meta-analysis.…”

Background We compared the diagnostic accuracy of longitudinal strain (LS) imaging during stress echocardiography with visual assessment of wall motion (WM) for detecting significant coronary artery disease (CAD). Methods Our systematic search included studies reporting diagnostic measures for LS imaging and visual assessment of WM for detecting significant CAD during stress echocardiography. Summary diagnostic accuracy measures including area under the curve (AUC), sensitivity, specificity, diagnostic odds ratio (DOR), and likelihood ratios (LRs) were estimated. Results In thirteen studies with 978 patients, ten studies used invasive coronary angiography as the reference standard. Pooled AUC for diagnosing significant CAD was 0.92 (95% confidence interval [CI] 0.89–0.94) for LS imaging as compared to 0.83 (95% CI 0.80–0.86), P < 0.001 for visual assessment of WM. LS imaging had higher sensitivity (88% [95% CI 84–92] vs 74% [95% CI 68–80], P < 0.001) and comparable specificity to visual assessment of WM (80% [95% CI 72–87] vs 83% [95% CI 74–90], P = 0.592). The DOR for LS imaging and visual assessment of WM was 31 and 15, P = 0.254, respectively. The positive LR was 4.5 for both; negative LR was 0.14 and 0.31, P = 0.002 for LS imaging and visual assessment of WM, respectively. Conclusions Longitudinal strain imaging during stress echocardiography has better diagnostic accuracy for detecting significant CAD as compared to visual assessment of WM. Studies using larger sample size and standardized techniques of strain measurement are required to further ascertain the added advantage of strain measurement over visual assessment alone.

“…Among these, stress echocardiography has been accepted as a valuable method in the detection of myocardial ischemia [1-8] outweighing the limitations imposed by the widely used treadmill stress test. In our center, stress echocardiography is preferentially performed using a treadmill exercise protocol.…”

“…This method allows the evaluation of cardiac function, rather than electrical activity, during exercise. Peteiro et al have firstly published imaging acquisition during exercise in 1999 [6] and one year after we published a detailful methodology article[7] and most recently other centers have also described it [8,9]. …”

“…Supine bicycle exercise is recommended because Doppler information can be obtained during the different stages of exercise [27], rather than post-treadmill imaging, when there are substantial and rapid changes in heart rate and loading conditions. In our center we perform echocardiography during exercise in the treadmill (Additional files 1 and 2 and 4) as Peteiro group also does [7,8,84,85]. Supine exercise is not as physiologic as treadmill exercise, the equipment is not as widely available as the treadmill and the maximum VO2 attained is at least 10% lower with bicycle [86].…”

Exercise stress echocardiography is the most frequently used stress test in our laboratory. Exercise echocardiography is used mainly in the study of patients with coronary artery disease. However, the technique is increasingly being used to study other diseases.In our centre, we use an original methodology, published by us in 2000, in which we evaluate heart function during exercise in the treadmill. After the exercise, patients are maintained in orthostatic position when appropriate or lying down in left lateral decubitus for further evaluation. Since this method seems to increase the quality and the quantity of information obtained in so many clinical arenas, we now present a detailed review of this methodology and its applications.
