Influence of Cardiac CT based disease severity and clinical symptoms on the diagnostic performance of myocardial perfusion.

Int J Cardiovasc Imaging 2019 Apr 23. Epub 2019 Apr 23.

Department of Cardiology, Hospital Unit West Jutland, Gl. Landevej 61, Herning, 7400, Denmark.

We aimed to identify factors influencing the sensitivity of perfusion imaging after an initial positive coronary computed tomography angiography (CCTA) using invasive coronary angiography (ICA) with conditional fractional flow reserve (FFR) as reference. Secondly we aimed to identify factors associated with revascularisation and to evaluate treatment outcome after ICA. We analysed 292 consecutive patients with suspected significant coronary artery disease (CAD) at CCTA, who underwent perfusion imaging with either cardiac magnetic resonance (CMR) or myocardial perfusion scintigraphy (MPS) followed by ICA with conditional FFR.

Early imaging biomarkers of lung cancer, COPD and coronary artery disease in the general population: rationale and design of the ImaLife (Imaging in Lifelines) Study.

Eur J Epidemiol 2019 Apr 23. Epub 2019 Apr 23.

Department of Radiology, University of Groningen, University Medical Center Groningen, Hanzeplein 1, 9713 GZ, Groningen, The Netherlands.

Lung cancer, chronic obstructive pulmonary disease (COPD), and coronary artery disease (CAD) are expected to cause most deaths by 2050. State-of-the-art computed tomography (CT) allows early detection of lung cancer and simultaneous evaluation of imaging biomarkers for the early stages of COPD, based on pulmonary density and bronchial wall thickness, and of CAD, based on the coronary artery calcium score (CACS), at low radiation dose. To determine cut-off values for positive tests for elevated risk and presence of disease is one of the major tasks before considering implementation of CT screening in a general population.

Improved visualization of the coronary arteries using motion correction during vasodilator stress CT myocardial perfusion imaging.

Eur J Radiol 2019 May 2;114:1-5. Epub 2019 Mar 2.

Departments of Medicine and Radiology, University of Chicago Medical Center, Chicago, IL, United States. Electronic address:

Background: Vasodilator stress computed tomography perfusion (sCTP) imaging is complementary to coronary CT angiography (CCTA), used to determine the hemodynamic significance of coronary artery disease. However, it requires a separate image acquisition due to motion artifacts caused by higher heart rates during stress, resulting in increased iodine contrast dose and radiation. We sought to determine whether a novel motion correction algorithm applied to stress images would improve the visualization of the coronary arteries to potentially allow CCTA + sCTP evaluation in a single scan.

Development of an innovative technology to segment luminal borders of intravascular ultrasound image sequences in a fully automated manner.

Comput Biol Med 2019 Mar 14;108:111-121. Epub 2019 Mar 14.

Faculty of Medicine and Health Sciences, Macquarie University, Sydney, NSW, 2109, Australia; School of Exercise, Biomedical and Health Sciences, Edith Cowan University, Perth, Australia.

Although intravascular ultrasound (IVUS) is the commonest intravascular imaging modality, it still is inefficient for clinical use as it requires laborious manual analysis. This study demonstrates the feasibility of a near real-time fully automated technology for accurate identification, detection, and quantification of luminal borders in intravascular images. This technology uses a combination of the novel approaches of a self-tuning engine, dynamic and static masking systems, radar-wise scan, and contour correction cycle method. Read More

Intracoronary near-infrared spectroscopy and the risk of future cardiovascular events.

Open Heart 2019 9;6(1):e000917. Epub 2019 Feb 9.

Department of Cardiology, Clinical Sciences, Lund University, Skåne University Hospital, Lund, Sweden.

Objectives: The objectives of this study were to investigate if findings by intracoronary near-infrared spectroscopy (NIRS) and intravascular ultrasound (IVUS) are associated with future cardiovascular events and if NIRS can differentiate culprit from non-culprit segments in patients with coronary artery disease.

Methods: The study included 144 patients with coronary artery disease undergoing percutaneous coronary intervention and combined NIRS-IVUS imaging at two Swedish hospitals. The NIRS-derived lipid core burden index (LCBI), the 4 mm segment with maximum LCBI (MaxLCBI) and the IVUS-derived maximum plaque burden (MaxPB) were analysed within the culprit segment and continuous 10 mm non-culprit segments of the index culprit vessels.

Complete atrioventricular block during exercise: New insights from an old test.

Monaldi Arch Chest Dis 2019 Jan 29;89(1). Epub 2019 Jan 29.

Cardiology Department, Vila Nova de Gaia/Espinho Hospital Centre.

Exercise stress testing can have a central role in the assessment of cardiovascular disease. Contemporary data, however, has highlighted the added value of imaging modalities over the exercise electrocardiogram in the investigation of coronary artery disease. Given the physiological changes associated with exercise and the possibility to address other parameters such as rhythm changes and the chronotropic response, exercise stress testing with continuous electrocardiographic monitoring can still have an important place in contemporary clinical practice.

Coronary atherosclerosis imaging by CT to improve clinical outcomes.

J Cardiovasc Comput Tomogr 2019 Mar 29. Epub 2019 Mar 29.

Royal Brompton and Harefield NHS Foundation Trust Departments of Cardiology and Radiology, London, UK; National Heart and Lung Institute, Faculty of Medicine, Imperial College, London, UK.

Coronary artery disease remains an important cause of morbidity and mortality world-wide. Coronary Computed Tomography Angiography (CCTA) has excellent diagnostic accuracy and the identification and stratification of coronary artery disease is associated with improved prognosis in multiple studies. Recent randomized controlled trials have shown that in patients with stable coronary artery disease, CCTA is associated with improved diagnosis, changes in investigations, changes in medical treatment and appropriate selection for revascularization.

State-of-the-art review article. Atherosclerosis affecting fat: What can we learn by imaging perivascular adipose tissue?

J Cardiovasc Comput Tomogr 2019 Mar 29. Epub 2019 Mar 29.

Department of Imaging and Medicine, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

Perivascular adipose tissue (PVAT) surrounding the human coronary arteries, secretes a wide range of adipocytokines affecting the biology of the adjacent vascular wall in a paracrine way. However, we have recently found that PVAT also behaves as a sensor of signals coming from the vascular wall, to which it reacts by changing its morphology and secretory profile. Indeed, vascular inflammation, a key feature of vascular disease pathogenesis, leads to the release of inflammatory signals that disseminate into local fat, inducing local lipolysis and inhibiting adipogenesis.
