AIMS To assess the feasibility of feature tracking (FT)-measured systolic strain post acute ST-segment elevation myocardial infarction (STEMI) and compare strain values to those obtained with tagging. METHODS Cardiovascular MRI at 1.5T was performed in 24 patients, 2.2 days post STEMI. Global and segmental circumferential (Ecc) and longitudinal (Ell)(More)
OBJECTIVE To compare the effects of transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) on aortic valve haemodynamics, ventricular reverse remodelling and myocardial fibrosis (MF) by cardiovascular magnetic resonance (CMR) imaging. DESIGN A 1.5 T CMR scan was performed preoperatively and 6 months postoperatively. (More)
There is currently no gold standard technique for quantifying infarct size (IS) and ischaemic area-at-risk (AAR [oedema]) on late gadolinium enhancement imaging (LGE) and T2-weighted short tau inversion recovery imaging (T2w-STIR) respectively. This study aimed to compare the accuracy and reproducibility of IS and AAR quantification on LGE and T2w-STIR(More)
BACKGROUND We evaluated the prevalence of left ventricular hypertrophy in elite footballers compared with sedentary controls. A total of 141 elite male professional footballers and 32 healthy sedentary controls were studied. Echocardiographic and demographic variables were compared between groups by unpaired t-test. RESULTS The prevalence of left(More)
AIM A pilot study to phenotype young adults (< 40 years) with Type 2 diabetes mellitus. METHODS Twenty people with Type 2 diabetes (aged 18-40 years), 10 lean and 10 obese control subjects underwent detailed assessment, including tagged cardiac magnetic resonance imaging, inflammatory proteins, lipids, vitamin D and maximal oxygen uptake. Outcomes were(More)
BACKGROUND The optimal management of patients found to have multivessel disease while undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction is uncertain. OBJECTIVES CvLPRIT (Complete versus Lesion-only Primary PCI trial) is a U.K. open-label randomized study comparing complete revascularization at(More)
BACKGROUND Left ventricular (LV) remodeling after acute myocardial infarction is associated with adverse prognosis. MicroRNAs (miRNAs) regulate the expression of several genes involved in LV remodeling. Our aim was to identify miRNAs associated with LV remodeling after acute myocardial infarction. METHODS AND RESULTS We studied 90 patients after first(More)
OBJECTIVE The purpose of our study was to assess the presence and extent of delayed contrast enhancement of ventricular myocardium in pulmonary artery hypertension. SUBJECTS AND METHODS Fifteen patients (age, 45.6 +/- 13 years; 13 New York Heart Association class III) with pulmonary artery hypertension (11 idiopathic, four systemic sclerosis) were(More)
PURPOSE To determine the interstudy reproducibility of myocardial strain and peak early-diastolic strain rate (PEDSR) measurement on cardiovascular magnetic resonance imaging (MRI) assessed with feature tracking (FT) and tagging, in patients with aortic stenosis (AS). MATERIALS AND METHODS Cardiac MRI was performed twice (1-14 days apart) in 18 patients(More)
The aim of the current study was to investigate whether alterations in N-terminal pro brain natriuretic peptide (NT-proBNP) reflect changes in right ventricular structure and function in pulmonary hypertension patients during treatment. The study consisted of 30 pulmonary hypertension patients; 15 newly diagnosed and 15 on long-term treatment. NT-proBNP,(More)
