Abstract Objectives To test the accuracy of clinical pre-test probability (PTP) for prediction of obstructive coronary artery disease (CAD) in a pan-European setting. Methods Patients with suspected CAD and stable chest pain who were clinically referred for invasive coronary angiography (ICA) or computed tomography (CT) were included by clinical sites participating in the pilot study of the European multi-centre DISCHARGE trial. PTP of CAD was determined using the Diamond-Forrester (D+F) prediction model initially introduced in 1979 and the updated D+F model from 2011. Obstructive coronary artery disease (CAD) was defined by one at least 50% diameter coronary stenosis by both CT and ICA. Results In total, 1440 patients (654 female, 786 male) were included at 25 clinical sites from May 2014 until July 2017. Of these patients, 725 underwent CT, while 715 underwent ICA. Both prediction models overestimated the prevalence of obstructive CAD (31.7%, 456 of 1440 patients, PTP: initial D+F 58.9% (28.1–90.6%), updated D+F 47.3% (34.2–59.9%), both p < 0.001), but overestimation of disease prevalence was higher for the initial D+F (p < 0.001). The discriminative ability was higher for the updated D+F 2011 (AUC of 0.73 95% confidence interval [CI] 0.70–0.76 versus AUC of 0.70 CI 0.67–0.73 for the initial D+F; p < 0.001; odds ratio (or) 1.55 CI 1.29–1.86, net reclassification index 0.11 CI 0.05–0.16, p < 0.001). Conclusions Clinical PTP calculation using the initial and updated D+F prediction models relevantly overestimates the actual prevalence of obstructive CAD in patients with stable chest pain clinically referred for ICA and CT suggesting that further refinements to improve clinical decision-making are needed. Trial registration https://www.clinicaltrials.gov/ct2/show/NCT02400229 Key Points • Clinical pre-test probability calculation using the initial and updated D+F model overestimates the prevalence of obstructive CAD identified by ICA and CT. • Overestimation of disease prevalence is higher for the initial D+F compared with the updated D+F. • Diagnostic accuracy of PTP assessment varies strongly between different clinical sites throughout Europe.

Abstract Aims Valvular heart disease can be identified by calcification on coronary computed tomography angiography (CCTA) and has been associated with adverse clinical outcomes. We assessed aortic and mitral valve calcification in patients presenting with stable chest pain and their association with cardiovascular risk factors, coronary artery disease, and cardiovascular outcomes. Methods and results In 1769 patients (58 ± 9 years, 56% male) undergoing CCTA for stable chest pain, aortic and mitral valve calcification were quantified using Agatston score. Aortic valve calcification was present in 241 (14%) and mitral calcification in 64 (4%). Independent predictors of aortic valve calcification were age, male sex, hypertension, diabetes mellitus, and cerebrovascular disease, whereas the only predictor of mitral valve calcification was age. Patients with aortic and mitral valve calcification had higher coronary artery calcium scores and more obstructive coronary artery disease. The composite endpoint of cardiovascular mortality, non-fatal myocardial infarction, or non-fatal stroke was higher in those with aortic [hazard ratio (HR) 2.87; 95% confidence interval (CI) 1.60–5.17; P &lt; 0.001] or mitral (HR 3.50; 95% CI 1.47–8.07; P = 0.004) valve calcification, but this was not independent of coronary artery calcification or obstructive coronary artery disease. Conclusion Aortic and mitral valve calcification occurs in one in six patients with stable chest pain undergoing CCTA and is associated with concomitant coronary atherosclerosis. Whilst valvular calcification is associated with a higher risk of cardiovascular events, this was not independent of the burden of coronary artery disease.

Abstract Introduction The European Society of Cardiology (ESC) guidelines on stable chest pain recommend the use of a pre-test probability (PTP) risk score (RS) which predicts the likelihood of coronary artery disease (CAD) to guide investigation and modality. The 2019 guidelines provide an updated PTPRS compared with 2013 guidelines, adjusted for the lower prevalence of coronary artery disease in contemporary populations. We assessed the performance of the two PTPRS in a cohort of patients with stable chest pain who underwent CT coronary angiography (CTCA) as the first line investigation. Methods We retrospectively searched a radiology database from January 2017 to June 2018. CTCA reported CAD degree of stenosis as normal/minimal stenosis, mild (30–50%), moderate (50–70%), or severe (&gt;70%) and retrospectively calculated ESC PTP scores for 2013 and 2019 guidelines. Results In total 652 patients underwent CTCA (mean age 55 yrs; IQR 48–63; 330 male). For ESC 2019 PTPRS there were no patients with PTP &gt;85%. 2 patients had PTP 50–85%; 1 patient had moderate stenosis and 1 mild stenosis on CTCA. 267 patients had PTP 15–50%; 23 (9%) had severe stenosis and 35 (13%) moderate stenosis. Finally, 379 patients had PTP &lt;15%; 11 (3%) had severe stenosis and 18 (5%) moderate CTCA stenosis. In comparison, ESC 2013 PTPRS had 2 patients with PTP &gt;85%; 1 had moderate stenosis and 1 had mild stenosis on CTCA. 149 patients had PTP 50–85%; 17 (11%) had severe stenosis and 23 (15%) moderate stenosis. A further 427 patients had a PTP 15–50%; 17 (4%) had severe stenosis and 32 (8%) had moderate stenosis. Lastly, 70 patients had a PTP &lt;15% and two (3%) were found to have a moderate stenosis on CTCA. Conclusions The updated ESC 2019 PTPRS appears to underestimate the presence of CAD given 11 (3%) patients with severe CTCA stenosis would have been missed. Although the 2013 PTPRS was thought to overestimate the prevalence of CAD, it did not miss anyone found to have severe CTCA stenosis. Furthermore, patients with evidence of mild or moderate CAD on CTCA may not have been investigated due to PTP &lt;15% and therefore may not be commenced on medical therapy, to derive a mortality benefit as demonstrated in SCOT-Heart trial.

Background: CAD management is important in prevention of disease progression. But we have very little study or research on the evolution of stable angina in amulatory patients without coronary antecedents and with obstructive coronary disease. Purpose: The objective of our study was to analyze the clinical and angiographic profil of patients with stable chest pain and to assess their angina status one year outcomes. Patients and methods: All patients who presented with symptomatic angina pectoris and/or signs of ischemia and first diagnosis of obstructive CAD in the Cardiology Departments of Idrissa Pouye General Hospital and Aristide Le Dantec National University Hospital Center of Dakar, from March 01, 2019 to December 31, 2020 were selected. The clinical characteristics, initial angiographic findings, therapeutic strategy and outcome within the first year were analyzed. Results: During the study period, 84 outpatients presenting with symptomatic stable chest pain and first obstructive coronary artery disease were selected. The mean age was 63.01± 9.37 years. Male preponderance was observed with 63(75%) patients; Clinical symptoms were dominated by typical pain with 46.4% (n=39) ; the risk factors were dominated by hypertension 61.9% (n=52); diabetes 41.7% (n=35) and dyslipidemia 33.3% (n=28). During follow-up, 10 patients (11.90%) remained untraceable while 9 patients (10.71%) were not available for check-up; 3 patients (3.57%) died during follow-up. Only 62 patients (73.80) could be evaluated; among those who were alive and controlled, 26 patients (41.93%) with angina at baseline still had angina symptoms, 2 patients (3.22%) had undergone myocardial infarction; one (1.61%) had undergone urgent revascularization; one (1.61%) patient developed heart failure. Finally 32 patients (51.61%) were event-free and angina-free Conclusion: The management of outpatients with stable chest pain and first obstructive CAD appears favourable, with good adherence to guideline-based therapies one year outcomes. Stable chest pain is not associated with an increased risk for adverse cardiovascular outcomes but there remains room for improvement in terms of risk factor control.

AbstractIdentification of obstructive coronary artery disease (OCAD) in patients with chest pain is a clinical challenge. The value of corrected QT interval (QTc) for the prediction of OCAD has yet to be established. We consecutively enrolled 1741 patients with suspected angina. The presence of obstructive OCAD was defined as ≥ 50% diameter stenosis by coronary angiography. The pre-test probability was evaluated by combining QTc prolongation with the CAD Consortium clinical score (CAD2) and the updated Diamond-Forrester (UDF) score. OCAD was detected in 661 patients (38.0%). QTc was longer in patients with OCAD compared with those without OCAD (444 ± 34 vs. 429 ± 28 ms, p < 0.001). QTc was increased by the severity of OCAD (P < 0.001). QTc prolongation was associated with OCAD (odds ratio (OR), 2.27; 95% confidence interval (CI), 1.81–2.85). With QTc, the C-statistics increased significantly from 0.68 (95% CI 0.66–0.71) to 0.76 (95% CI 0.74–0.78) in the CAD2 and from 0.64 (95% CI 0.62–0.67) to 0.74 (95% CI 0.72–0.77) in the UDF score, respectively. QT prolongation predicted the presence of OCAD and the QTc improved model performance to predict OCAD compared with CAD2 or UDF scores in patients with suspected angina.

BACKGROUND. Patients with chest pain and no evidence of obstructive coronary artery disease on angiography (NoCAD) are frequently considered not to have significant pathology and their symptoms trivialized. This study compared the health status of patients with NoCAD, obstructive coronary artery disease (CAD) and healthy subjects. METHOD. Patients undergoing angiography within the preceding 12 months for the investigation of chest pain were categorized as NoCAD or CAD on the basis of the angiographic findings and completed a health-related quality of life instrument, the Short Form-36 (SF-36). These were compared with a ‘healthy control’ group that were randomly selected from the electronic white pages and recruited if they had no self-reported history of cardiovascular disease. Cross sectional comparisons between the three groups were age adjusted and performed using liner regression. RESULTS. As shown in the table below, the healthy controls were significantly younger and therefore comparison of SF36 scores were age adjusted. All SF-36 sub-scales (except for bodily pain) and summary scores (see table ), were significantly lower in the CAD and NoCAD groups compared to the healthy controls. There were no differences in SF-36 scores between NoCAD and CAD. CONCLUSION. Compared with a healthy population, patients with stable CAD and NoCAD have significantly poorer quality of life asF-36. Future management strategies need to address the health outcomes in these patients. Healthy Controls (n = 3168) NoCAD (n = 320) CAD (n = 828) Age 52 ± 15 57 ± 12 * 62 ± 11 # SF-36: Physical Summary Score 49 ± 10 41 ± 11 * 41 ± 11 # SF-36: Mental Summary Score 51 ± 10 46 ± 11 * 46 ± 11 # * p <0.01 for healthy controls vs NoCAD, # p <0.01 for healthy controls vs CAD
