Non-atherosclerotic coronary artery diseases are being increasingly recognised as causes of acute coronary events. Invasive coronary angiography frequently fails to identify the abnormalities in the proximal course of coronary arteries and coronary wall, while computed tomography coronary angiography (CTCA) allows for acquisition of more detailed information. CTCA serves as a reliable method for evaluating patients with non-atherosclerotic coronary artery diseases. The purpose of this article is to provide an overview of non-atherosclerotic abnormalities that may be demonstrated on CTCA...

CT coronary angiography (CTCA) is increasingly being used to diagnose coronary artery disease (CAD). Recent technological advancements, including dual energy CT and improved gantry times, have led to the ability to image coronary arteries with excellent spatial resolution at low radiation doses. Atheromatous plaques can be identified using CTCA and assessed to establish the risk of acute coronary syndrome from each individual plaque. If CTCA identifies CAD, it should then be used in conjunction with functional testing or invasive angiography with physiological assessment to establish the significance of coronary disease in an individual patient...

Rapid technological advances in computed tomography (CT) have allowed CT coronary angiography (CTCA) to be delivered at low radiation dose and high diagnostic accuracy. Due to its high negative predictive value for coronary artery disease, it has become a gatekeeper for the assessment of patients with chest pain of recent onset. Second line functional assessment of a detected coronary stenosis relies mostly on other imaging modalities. Functional assessment of coronary artery disease by CT is therefore an attractive addition to CTCA...

BACKGROUND: Left main coronary artery (LMCA) compression is increasingly recognized as a cause of angina in pulmonary arterial hypertension (PAH). OBJECTIVES: This study aimed to evaluate the prevalence of LMCA extrinsic compression from a dilated pulmonary artery (PA) in patients with PAH and angina or angina-like symptoms, determine the usefulness of screening with computed tomography coronary angiography (CTCA), and assess the safety and efficacy of percutaneous coronary interventions (PCIs)...

The aim of this study is to evaluate the effect of single-nucleotide polymorphisms (SNPs) of the PPARGC1A and UCP1 genes on impaired fasting glucose (IFG) or type 2 diabetes mellitus (T2DM) and the haplotype-based interaction between these genes.A cross-sectional study was conducted by cluster sampling in Henan province, China. Based on the level of fasting plasma glucose (FPG) and the history of T2DM, the participants were divided into 2 groups; 83 individuals were in the IFG+DM group (those with IFG or T2DM) and 445 individuals were in the NFPG group (those with normal FPG)...

OBJECTIVE: To assess the impact of elevated heart rate (HR) on the diagnostic accuracy and image quality of second-generation 320-detector computed tomography coronary angiography (320-CTCA). METHODS: Consecutive patients with suspected coronary disease referred for invasive coronary angiography (ICA) were prospectively recruited and underwent 320-CTCA. Pre-scan beta-blockers were administered if native HR>80 bpm and post-scan cohorts stratified by traditional (HR ≤60 bpm) and elevated HR (61-80 bpm)...

REVIEW
Adam Timmis, Carl A Roobottom
In the 2016 update of the stable chest pain guideline, the National Institute for Health and Care Excellence (NICE) has made radical changes to the diagnostic paradigm that it-like other international guidelines-had previously placed at the centre of its recommendations. No longer are quantitative assessments of the disease probability considered necessary to determine the need for diagnostic testing and the choice of test. Instead, the recommendation is for no diagnostic testing if chest pain is judged to be 'non-anginal' and CT coronary angiography (CTCA) in patients with 'typical' or 'atypical' chest pain with additional perfusion imaging only if there is uncertainty about the functional significance of coronary lesions...

Aims: CT calcium scoring (CTCS) and CT cardiac angiography (CTCA) are widely used in patients with stable chest pain to exclude significant coronary artery disease (CAD). We aimed to resolve uncertainty about the prevalence of obstructive coronary artery disease and long-term outcomes in patients with a zero-calcium score (ZCS). Methods and results: Consecutive patients with stable cardiac symptoms referred for CTCS or CTCS and CTCA from chest pain clinics to a tertiary cardiothoracic centre were prospectively enrolled...

136 Background: Cancer Treatment Centers of America, Inc. (CTCA) is a national network of five hospitals that specialize in treating patients fighting complex or advanced-stage cancer. During the fall of 2013, two of the five centers began the pursuit of Quality Oncology Practice Initiative (QOPI) certification. A third site began QOPI certification the spring of 2014 and the remaining two sites followed suit the spring of 2015. This process brought attention to the patient population receiving oral chemotherapy and the importance of careful monitoring of those self-administering their cancer treatment regimens...

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...

AIMS: Coronary artery aneurysms (CAAs) are incidentally revealed by coronary angiography and consist in a localized dilation of a coronary artery. Although invasive coronary angiography (ICA) is the gold standard imaging technique, it can lead to the underestimation of CAAs diameter in presence of parietal thrombi. Computed tomography coronary angiography (CTCA) is a very sensitive tool in CAAs detection and provides a clear visualization of coronary lumen highlighting intraluminal thrombi...

Silent myocardial ischemia is typically defined as objective evidence of myocardial ischemia in patients without subjective ischemia symptoms. Currently, coronary artery angiography is the gold standard for diagnosis of asymptomatic coronary artery disease (CAD). Computed tomography coronary angiography (CTCA) can visually demonstrate the morphology, trend and extent of coronary stenosis and is commonly used in clinical screening of CAD. Myocardial perfusion imaging can be used not only to identify whether anatomical stenosis causes myocardial dysfunction, but to also assess the risk stratification and prognosis of myocardial disease (MD)...
