Proconvertase Furin Is Downregulated in Postural Orthostatic Tachycardia Syndrome.
(Frontiers Media SA, 2019-03-29)Background: Postural Orthostatic Tachycardia Syndrome (POTS) is a cardiovascular autonomic disorder characterized by orthostatic intolerance and high prevalence among young women. The etiology of POTS is uncertain, though ... -
Prognostic Significance of Left Ventricular Noncompaction: Systematic Review and Meta-Analysis of Observational Studies.
(American Heart Association, Inc., by Wolters Kluwer Health, Inc, 2020-01-21)BACKGROUND: Although left ventricular noncompaction (LVNC) has been associated with an increased risk of adverse cardiovascular events, the accurate incidence of cardiovascular morbidity and mortality is unknown. We, ... -
The Prognostic Significance of Quantitative Myocardial Perfusion: An Artificial Intelligence Based Approach Using Perfusion Mapping.
(Wolters Kluwer Health, Inc., 2020-02-14)Background: Myocardial perfusion reflects the macro- and microvascular coronary circulation. Recent quantitation developments using cardiovascular magnetic resonance (CMR) perfusion permit automated measurement clinically. ... -
Prognostic Value of Pulmonary Transit Time and Pulmonary Blood Volume Estimation Using Myocardial Perfusion CMR.
(Elsevier, 2021-05-19)OBJECTIVES: The purpose of this study was to explore the prognostic significance of PTT and PBVi using an automated, inline method of estimation using CMR. BACKGROUND: Pulmonary transit time (PTT) and pulmonary blood volume ... -
Progression of myocardial fibrosis in hypertrophic cardiomyopathy: mechanisms and clinical implications.
(2018-10-24)Aims: Myocardial fibrosis as detected by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) is a powerful prognostic marker in hypertrophic cardiomyopathy (HCM) and may be progressive. The precise ... -
Prospective association between handgrip strength and cardiac structure and function in UK adults.
(2018)BACKGROUND: Handgrip strength, a measure of muscular fitness, is associated with cardiovascular (CV) events and CV mortality but its association with cardiac structure and function is unknown. The goal of this study was ... -
Protocol and quality assurance for carotid imaging in 100,000 participants of UK Biobank: development and assessment.
(2017-11)Background Ultrasound imaging is able to quantify carotid arterial wall structure for the assessment of cerebral and cardiovascular disease risks. We describe a protocol and quality assurance process to enable carotid ... -
Pulmonary blood volume index as a quantitative biomarker of haemodynamic congestion in hypertrophic cardiomyopathy.
(2019-12-01)AIMS : The non-invasive assessment of left ventricular (LV) diastolic function and filling pressure in hypertrophic cardiomyopathy (HCM) is still an open issue. Pulmonary blood volume index (PBVI) by cardiovascular magnetic ... -
Quality Control-Driven Image Segmentation Towards Reliable Automatic Image Analysis in Large-Scale Cardiovascular Magnetic Resonance Aortic Cine Imaging
(Springer, Cham, 2019-10-10)© 2019, Springer Nature Switzerland AG. Recent progress in fully-automated image segmentation has enabled efficient extraction of clinical parameters in large-scale clinical imaging studies, reducing laborious manual ... -
A radiomics approach to computer-aided diagnosis with cardiac cine-MRI
(Springer Link, 2018-03-15)© Springer International Publishing AG, part of Springer Nature 2018. Computer-aided diagnosis of cardiovascular diseases (CVDs) with cine-MRI is an important research topic to enable improved stratification of CVD patients. ... -
Radiomics signatures of cardiovascular risk factors in cardiac MRI: Results from the UK Biobank
(Frontiers Media, 2020-11-02) -
A Randomised, Double-Blind, Placebo-Controlled, Cross-Over, Single-Centre Study to Investigate the Acute Lung Deflation Effects of Fluticasone Furoate/Vilanterol Inhalation Powder 100/25mcg Once Daily on Cardiac Biventricular Function and Arterial Stiffness in Adults with COPD
