The impact of menopausal hormone therapy (MHT) on cardiac structure and function: Insights from the UK Biobank imaging enhancement study.
(2018)BACKGROUND: The effect of menopausal hormone therapy (MHT)-previously known as hormone replacement therapy-on cardiovascular health remains unclear and controversial. This cross-sectional study examined the impact of MHT ... -
Independent Left Ventricular Morphometric Atlases Show Consistent Relationships with Cardiovascular Risk Factors: A UK Biobank Study
(Nature Publishing Group, 2019-02-04)Left ventricular (LV) mass and volume are important indicators of clinical and pre-clinical disease processes. However, much of the shape information present in modern imaging examinations is currently ignored. Morphometric ... -
Ineffective and prolonged apical contraction is associated with chest pain and ischaemia in apical hypertrophic cardiomyopathy.
(2018-01-15)OBJECTIVES: To investigate the hypothesis that persistence of apical contraction into diastole is linked to reduced myocardial perfusion and chest pain. BACKGROUND: Apical hypertrophic cardiomyopathy (HCM) is defined by ... -
Inflammatory risk and cardiovascular events in patients without obstructive coronary artery disease: the ORFAN multicentre, longitudinal cohort study.
(Elsevier, 2024-05-29)BACKGROUND: Coronary computed tomography angiography (CCTA) is the first line investigation for chest pain, and it is used to guide revascularisation. However, the widespread adoption of CCTA has revealed a large group of ... -
Initial experience with the convergent procedure for longstanding persistent atrial fibrillation: A 5 year dataset.
(2020-06)In patients with longstanding persistent atrial fibrillation (AF), outcomes from catheter ablation remain suboptimal. The convergent procedure combines minimally invasive surgical ablation with subsequent catheter ablation, ... -
Inline perfusion mapping provides insights into the disease mechanism in hypertrophic cardiomyopathy.
(2019-12-10)OBJECTIVE: In patients with hypertrophic cardiomyopathy (HCM), the role of small vessel disease and myocardial perfusion remains incompletely understood and data on absolute myocardial blood flow (MBF, mL/g/min) are scarce. ... -
Integrating CT Myocardial Perfusion and CT-FFR in the Work-Up of Coronary Artery Disease
(Elsevier/Science Direct, 2017-07)Objectives The aim of this study was to investigate the individual and combined accuracy of dynamic computed tomography (CT) myocardial perfusion imaging (MPI) and computed tomography angiography (CTA) fractional flow ... -
Joint learning of motion estimation and segmentation for cardiac MR image sequences
(2018-01-01)© Springer Nature Switzerland AG 2018. Cardiac motion estimation and segmentation play important roles in quantitatively assessing cardiac function and diagnosing cardiovascular diseases. In this paper, we propose a novel ... -
Joint motion estimation and segmentation from undersampled cardiac mr image
(2018-01-01)© 2018, Springer Nature Switzerland AG. Accelerating the acquisition of magnetic resonance imaging (MRI) is a challenging problem, and many works have been proposed to reconstruct images from undersampled k-space data. ... -
LB01.07: ELEVATED BLOOD PRESSURE WITHOUT HYPERTROPHY RAISES LEFT VENTRICULAR EJECTION FRACTION.
(2015-06)OBJECTIVE: Hypertension remains a major cause of cardiovascular morbidity and mortality worldwide. Persistent blood pressure (BP) elevation may lead to left ventricular (LV) hypertrophy and heart failure. We wanted to ...
