Abstract
Despite the good specificity of exercise stress echocardiography (ESE) for the detection of coronary artery disease (CAD), false positive (FP) results may occur. We have previously reported that chest abnormalities may affect parameters of cardiac contractility. The influence of chest shape on ESE results has never been previously investigated. We retrospectively analyzed 160 consecutive patients (64.4 ± 13.0-year old, 91 women) who had undergone coronary angiography at our Institution because of positive ESE, between June 2014 and May 2020. Modified Haller index (MHI; chest transverse diameter over the distance between sternum and spine) was assessed in all patients. Obstructive CAD was diagnosed by ≥ 70% stenosis in any epicardial coronary artery. Outcome was false-positivity at ESE. 80.6% of patients were diagnosed with obstructive CAD, while 19.4% had no CAD (FP). We separately analyzed patients with normal chest shape (MHI ≤ 2.5) and those with concave-shaped chest wall (MHI > 2.5). These latter were mostly women with small cardiac chambers, mitral valve prolapse (MVP) and exercise-induced ST-segment changes. Likelihood of false-positivity was significantly higher in subjects with MHI > 2.5 than those with MHI ≤ 2.5 (30.7% vs 9.4%, p = 0.001). By multivariate logistic regression analysis, MHI > 2.5 (OR 4.04, 95%CI 1.45-11.2, p = 0.007), MVP (OR 3.47, 95%CI 1.32-9-12, p = 0.01) and dyssynergy in the left circumflex territory (OR = 3.35, 95%CI 1.26-8.93, p = 0.01) were independently associated with false-positivity. Concave-shaped chest wall (MHI > 2.5) may be associated with false-positive stress echocardiographic result. Mechanisms underpinning this finding need to be further explored.

Abstract
Background: The influence of chest conformation on outcome of patients with suspected coronary artery disease (CAD) is actually unknown. Materials and Methods: This retrospective study included all consecutive patients who underwent exercise stress echocardiography (ESE) for suspected CAD at our institution between February 2011 and September 2019. Modified Haller index (MHI; chest transverse diameter over the distance between sternum and spine) was assessed in all patients. Obstructive CAD was diagnosed by ≥70% stenosis in any epicardial coronary artery. During the follow-up time, we evaluated the occurrence of any of the following: (1) cardiovascular (CV) hospitalizations and (2) cardiac death or sudden death. Results: A total of 1091 consecutive patients (62.4 ± 12.6 years, 57.2% of men) were included in the study. Patients with normal chest shape (MHI ≤2.5) and those with concave-shaped chest wall (MHI >2.5) were separately analyzed. A positive ESE was diagnosed in 171 patients of which 80.7% had an obstructive CAD (true positive), while 19.3 not (false positive [FP]). Majority of FP ESE (70.9%) derived from concave-shaped chest wall group. During follow-up time (2.5 ± 1.9 years), 9 patients died and 281 were hospitalized because of heart failure (163), acute coronary syndromes (39), and arrhythmias (79). At the multivariate Cox regression analysis, age (heart rate [HR]: 1.02, 95% confidence interval [CI]: 1.01–1.03), MHI >2.5 (HR: 0.39, 95% CI: 0.26–0.56), diabetes mellitus (HR: 4.89, 95% CI: 3.78–6.32), horizontal ST depression ≥1 mm (HR: 2.86, 95% CI: 1.98–4.15), peak exercise average E/e' ratio (HR: 1.08, 95% CI: 1.06–1.10), and peak exercise wall motion score index (HR: 1.79, 95% CI: 1.36–2.35) were independently correlated with outcome. Conclusions: Patients with concave-shaped chest wall (MHI >2.5) have a significantly lower probability of CV events than those with normal chest shape (MHI ≤2.5) over a medium-term follow-up. A noninvasive chest shape assessment could identify subjects at lower risk of CV events.

Appropriate use criteria implementation with modified Haller index for predicting stress echocardiographic results and outcome in a population of patients with suspected coronary artery disease.

Abstract
The hypothesis that modified Haller index (MHI) integration with the existing appropriate use criteria (AUC) categories may predict exercise stress echocardiography (ESE) results and outcome of patients with suspected coronary artery disease (CAD) has never been previously investigated. We retrospectively analyzed 1230 consecutive patients (64.8 ± 13.1 years, 58.9% men) who underwent ESE for suspected CAD between February 2011 and September 2019 at our institution. MHI (chest transverse diameter over the distance between sternum and spine) was assessed in all patients. A true positive (TP) ESE was a positive ESE with obstructive CAD according to subsequent coronary angiography. During follow-up time, we evaluated the occurrence of any of the following: (1) cardiovascular (CV) hospitalizations; (2) Cardiac death or sudden death. Overall, 734 (59.7%), 357 (29.0%) and 139 (11.3%) indications for ESE were classified as appropriate (Group 1), rarely appropriate (Group 2) and which may be appropriate (Group 3), respectively. A funnel chest (defined by an MHI > 2.5) was detected in 30.3%, 82.1% and 49.6% of Groups 1, 2 and 3 subjects, respectively (p < 0.0001). On multivariate logistic regression analysis, male sex (OR 1.41, 95%CI 1.02-2.03, p = 0.01) and type-2 diabetes (OR 3.63, 95%CI 2.49-5.55, p = 0.001) were directly correlated to a TP ESE, while "rarely appropriate" indication for ESE with MHI > 2.5 (OR 0.16, 95%CI 0.11-0.22, p < 0.0001) showed a significant inverse correlation with the outcome. During a mean follow-up of 2.5 ± 1.9 years, 299 CV events occurred: 76.4%, 3.5% and 20.1% in Groups 1, 2 and 3, respectively. On multivariate Cox regression analysis, smoking (HR 1.33, 95%CI 1.19-1.48), type 2 diabetes (HR 2.28, 95%CI 1.74-2.97), dyslipidemia (HR 3.51, 95%CI 2.33-5.15), beta-blockers (HR 0.55, 95%CI 0.41-0.75), statins (HR 0.60, 95%CI 0.45-0.80), peak exercise average E/e' ratio (HR 1.08, 95%CI 1.06-1.09), positive ESE (HR 3.12, 95%CI 2.43-4.01) and finally "rarely appropriate" indication for ESE with MHI > 2.5 (HR 0.15, 95%CI 0.08-0.23) were independently associated with CV events. The implementation of AUC categories with MHI assessment may select a group of patients with extremely low probability of both TP ESE and adverse CV events over a medium-term follow-up. A simple noninvasive chest shape assessment could reduce unnecessary exams.

Abstract
OBJECTIVES Patients with permanent pacemaker (PPM) implantation may have altered coronary perfusion patterns that may influence the accuracy of myocardial perfusion examination modalities, which was observed in previous studies but with limited statistic power. Our aim was to examine the performance of thallium-201 (TL-201) myocardial perfusion examination in patients with implanted PPM. METHODS Data of consecutive patients from our institution who had coronary angiography examination followed by TL-201 myocardial perfusion examination in pairs within 1 year were collected between January 2010 and December 2016 and were divided into PPM and control groups. Propensity score matching (PSM) was performed to compare the positive predictive value (PPV) of perfusion examinations. RESULTS A total of 934 pairs of studies were evaluated, with 81 in the PPM group and 853 controls. The PPV decreased significantly in the PPM group (28.2 vs. 62.9%, P < 0.001). The finding of large (>20%) ischemic areas correlated significantly with all-cause mortality in the control group (OR, 2.34; P = 0.001), but not in the PPM group (OR,1.05; P = 0.943). After PSM, the PPV was still significantly lower in the PPM group than in the non-PPM group (28.6 vs. 66.2%, P < 0.001). CONCLUSION Study results do not support the appropriateness of using TL-201 perfusion examinations for risk stratification in patients with implanted PPM.Video Abstract: http://links.lww.com/NMC/A181.

Abstract
Cardiovascular imaging has significantly evolved since the turn of the century. Progress in the last two decades has been marked by advances in every modality used to image the heart, including echocardiography, cardiac magnetic resonance, cardiac CT and nuclear cardiology. There has also been a dramatic increase in hybrid and fusion modalities that leverage the unique capabilities of two imaging techniques simultaneously, as well as the incorporation of artificial intelligence and machine learning into the clinical workflow. These advances in non-invasive cardiac imaging have guided patient management and improved clinical outcomes. The technological developments of the past 20 years have also given rise to new imaging subspecialities and increased the demand for dedicated cardiac imagers who are cross-trained in multiple modalities. This state-of-the-art review summarizes the evolution of multimodality cardiac imaging in the 21st century and highlights opportunities for future innovation.

Abstract
IMPORTANCE Patients with abnormal (positive) exercise electrocardiography, but normal stress echocardiography (+ECG/-Echo) are commonly encountered in clinical practice; however, the prognostic significance of this discordant result is unclear. OBJECTIVE To determine whether patients with +ECG/-Echo have a higher rate of adverse clinical events and a poorer prognosis than patients with negative exercise ECG and normal stress Echo imaging (-ECG/-Echo). DESIGN, SETTING, AND PARTICIPANTS Between January 1, 2000, and February 28, 2014, a total of 47 944 consecutive patients without known coronary artery disease who underwent exercise stress Echo at Duke University Medical Center were evaluated for inclusion in this observational cohort study. Data analysis was conducted from January 1, 2000, to December 31, 2016. INTERVENTIONS/EXPOSURES Patients were categorized as having -ECG/-Echo, +ECG/-Echo, or +Echo (-ECG/+Echo and +ECG/+Echo). MAIN OUTCOMES AND MEASURES The primary outcome was a composite end point of death, myocardial infarction, hospitalization for unstable angina, and coronary revascularization. Secondary outcomes included individual adverse events and downstream testing. RESULTS After excluding submaximal tests and nondiagnostic ECG or stress imaging results, 15 077 patients (mean [SD] age, 52 [13] years; 6228 [41.3%] men) were classified by stress test results. Of these, 12 893 patients (85.5%) had -ECG/-Echo, 1286 patients (8.5%) had +ECG/-Echo, and 898 patients (6.0%) had +Echo. Through a median follow-up of 7.3 (interquartile range, 4.4-10.0) years, the composite end point occurred in 794 patients with -ECG/-Echo (8.5%), 142 patients with +ECG/-Echo (14.6%), and 297 patients with +Echo (37.4%). Death occurred in 425 patients with -ECG/-Echo (4.8%), 50 patients with +ECG/-Echo (5.9%), and 70 patients with +Echo (11.2%). Myocardial infarction occurred in 195 patients with -ECG/-Echo (2.2%), 31 patients with +ECG/-Echo (3.6%), and 59 patients with +Echo (8.7%). The addition of stress ECG findings to clinical and exercise data yielded incremental prognostic value. Patients with -ECG/-Echo imaging results had the least downstream testing (2.3%), followed by +ECG/-Echo (12.8%), and +Echo (33.6%) (P < .001). CONCLUSIONS AND RELEVANCE The presence of +ECG results with normal stress Echo imaging may identify a population of patients who are at slightly increased risk for adverse cardiac events, which was not previously recognized. Further study is needed to determine whether these patients will benefit from intensification of medical management.
