BACKGROUND: Exercise treadmill test (ETT) is commonly the first-line investigation in troponin-negative chest pain patients. Inconclusive results are common and often lead to repeated functional testings. Coronary computed tomographic angiography (CCTA) has excellent negative predictive value for coronary artery disease detection and may play an important role in their diagnostic workup. We aim to analyse ETT and CCTA findings to understand their modern roles in intermediate risk chest pain population with inconclusive ETT...

BACKGROUND: The use of noninvasive diagnostics in coronary artery disease remains underdeveloped. To date, there is no simple and inexpensive method that can lead to a reliable diagnosis. Aside from costly and elaborate imaging techniques, exercise ECG, with its rather moderate sensitivity and specificity, is the main diagnostic method available. METHODS: In this prospective study of 109 patients, the diagnostic value of cardiogoniometry (CGM), a three-dimensional, computer-analyzed vector cardiogram, was determined before and after physical stress, and the results were compared with those obtained from a stress test...

BACKGROUND: In the absence of the existing acute coronary syndrome guidelines directing the clinical practice implementation of ED screening and diagnosis, there is variable screening and diagnostic clinical practice across ED facilities. This practice diversity may be warranted. Understanding the variability may identify opportunities for more consistent practice. METHODS: This is a cross-sectional clinical practice epidemiology study with the emergency department (ED) as the unit of analysis characterizing variability in the acute coronary syndrome (ACS) evaluation across 62 diverse EDs...

BACKGROUND: Coronary heart disease (CHD) is the leading cause of death worldwide. Research indicates that coronary atherosclerosis is the most frequent cause of CHD. Evidence is scarce concerning the clinical efficacy of fibrinogen or neutrophil-lymphocyte ratio (NLR) measurement in risk-stratifying patients with chronic stable angina. OBJECTIVES: To examine the independent and incremental prognostic value of fibrinogen and neutrophil-lymphocyte ratio (NLR) for angiographically-detected coronary artery disease (CAD)...

INTRODUCTION: To ensure flight safety military aircrew undergo regular clinical and occupational assessment. Coronary artery calcium scoring (CACS) has been established as an imaging modality to noninvasively assess coronary artery disease (CAD). CT coronary angiography (CTCA) potentially offers a more accurate assessment of CAD, but has not been formally assessed in military aircrew. This retrospective cohort study is designed to compare the theoretical differences in downstream investigations and occupational outcomes in aircrew with suspected CAD comparing CTCA with existing CACS pathways...

OBJECTIVES: We sought to determine the safety of regadenoson stress testing in patients with PH. BACKGROUND: PH is increasingly recognized at more advanced ages. As many as one-third of patients with PH have coronary artery disease. Because of their physical limitations, patients with PH are unable to adequately exercise. Regadenoson can potentially have an adverse impact due to their tenuous hemodynamics. Current guidelines suggest performing a coronary angiography in patients with PH who have angina or multiple coronary risk factors...

BACKGROUND: Exercise-induced ST-segment elevation (STE) in lead aVR may be an important indicator of prognostically important coronary artery disease (CAD). However, the prevalence and associated clinical features of exercise-induced STE in lead aVR among consecutive patients referred for exercise stress electrocardiography (ExECG) is unknown. METHODS: All consecutive patients receiving a Bruce protocol ExECG for the diagnosis of CAD at a tertiary care academic center were included over a two-year period...

Obstructive sleep apnea (OSA) is a common sleep-related breathing disorder associated with "cardiovascular stress", i.e. cardiovascular risk factors, cardiovascular diseases, and an increased risk of heart failure, stroke, and death. Experimental and clinical studies have characterized potential underlying mechanisms including biventricular dysfunction, atherosclerosis, and arrhythmia. Assessment of these cardiovascular features of OSA requires a spectrum of clinical tools including ECG, echocardiography, exercise testing, and angiography...

BACKGROUND: Exercise-stress electrocardiography (ECG) is initially recommended for the diagnosis of coronary artery disease. But its value has been questioned in women because of suboptimal diagnostic accuracy. Stress echocardiography had been reported to have comparable test accuracy in women. But the data comparing the diagnostic accuracy of exercise-stress ECG and stress echocardiography directly are few. The aim of the study was to compare the diagnostic accuracy of exercise-stress ECG and dobutamine stress echocardiography (DSE) in Korean women...

BACKGROUND: The exercise electrocardiographic stress test (ExET) is the most widely used non-invasive diagnostic method to detect coronary artery disease. However, the sole ST depression criteria (ST-max) have poor specificity for coronary artery disease in patients with left ventricular hypertrophy. We hypothesised that ST-segment depression/heart rate hysteresis, depicting the relative behaviour of ST segment depression during the exercise and recovery phase of the test might increase the diagnostic accuracy of ExET for coronary artery disease detection in such patients...

Cardiologists in the UK use clinical practice guidelines from the National Institute for Health and Care Excellence (NICE) and from the European Society of Cardiology (ESC) to aid clinical decision-making. This review compares their recommendations regarding stable angina. NICE's diagnostic algorithm changed clinical practice in the UK, with most cardiologists moving from the exercise ECG towards newer, more accurate imaging modalities such as CT and MRI for diagnostic testing in patients with a low or medium probability of coronary artery disease (CAD), and directly to invasive coronary angiography in patients with a high probability of CAD...

BACKGROUND: Most exercise-related cardiac arrests in men aged ≥45 years are due to coronary artery disease (CAD). The current sports medical evaluation (SME) of middle-aged sportsmen includes medical history, physical examination and resting and exercise electrocardiography (ECG). We investigated the added value of low-dose cardiac computed tomography (CCT) - both non-contrast CT for coronary artery calcium scoring (CACS) and contrast-enhanced coronary CT angiography (CCTA) - in order to detect occult CAD in asymptomatic recreational sportsmen aged ≥45 years without known cardiovascular disease...

BACKGROUND: There are limited data to guide the optimum approach to patients presenting with angina after coronary artery bypass grafting (CABG). Although often referred for invasive angiography, the effectiveness of this is unknown; angina may also result from diffuse distal or micro-vascular coronary disease and it is not known how often targets for intervention are identified. METHODS: Retrospective review of 50,460 patients undergoing angiography in East Denmark between January 2010 and December 2014...

BACKGROUND: The Prospective Multicenter Imaging Study for Evaluation of Chest Pain (PROMISE) trial found that initial use of ≥64 detector-row computed tomography angiography versus standard functional testing strategies (exercise ECG, stress nuclear methods, or stress echocardiography) did not improve clinical outcomes in 10 003 stable symptomatic patients with suspected coronary artery disease requiring noninvasive testing. Symptom burden and quality of life (QOL) were major secondary outcomes...

OBJECTIVE: Identification of right ventricular (RV) abnormalities is important in patients with suspected coronary artery disease (CAD). RV activity can be better visualized on myocardial single-photon emission computerized tomography (SPECT) using a higher sensitivity cadmium-zinc-telluride (CZT) detector. The aim of this study was to investigate the clinical significance of RV/left ventricular (LV) uptake ratios during exercise thallium-201 SPECT using CZT detectors. PATIENTS AND METHODS: A total of 102 patients underwent treadmill ECG-gated SPECT, coronary angiography, and echocardiography...

Several tests exist for diagnosing coronary artery disease, with varying accuracy and cost. We sought to provide cost-effectiveness information to aid physicians and decision-makers in selecting the most appropriate testing strategy. We used the state-transitions (Markov) model from the Brazilian public health system perspective with a lifetime horizon. Diagnostic strategies were based on exercise electrocardiography (Ex-ECG), stress echocardiography (ECHO), single-photon emission computed tomography (SPECT), computed tomography coronary angiography (CTA), or stress cardiac magnetic resonance imaging (C-MRI) as the initial test...

Pulmonary hypertension (PH) is a condition of multiple aetiologies with underestimated prevalence and incidence. Indeed, despite access to modern therapies, pulmonary hypertensive vascular disease (PHVD) remains a progressive, usually life-limiting condition, severely impacting on the patients' well-being. We herein provide practical, expert consensus recommendations on the initial diagnostic work-up, clinical management and follow-up of children and adolescents with PH/PHVD, including a diagnostic algorithm...
