BACKGROUND The optimum timing of surgery in asymptomatic patients with chronic severe primary degenerative mitral regurgitation (MR) remains controversial, and further markers are needed to improve decision-making. There are limited data that wall stress is increased in MR and may result in ventricular fibrosis. We investigated the hypothesis that chronic(More)
Early-stage chronic kidney disease (CKD) is an under-recognized highly prevalent cardiovascular (CV) risk factor. Despite a clustering of conventional atherosclerotic risk factors, it is hypothesized that nonatherosclerotic processes, including left ventricular (LV) hypertrophy and fibrosis, account for a significant excess of CV risk. This cross-sectional(More)
BACKGROUND Alström syndrome is a rare inherited ciliopathy with progressive multisystem involvement. Dilated cardiomyopathy is common in infancy and recurs or presents de novo in adults with high rates of premature cardiovascular death. Although Alström syndrome is characterised by fibrosis in solid organs such as the liver, the pathogenesis of related(More)
Background Early stage chronic kidney disease (CKD) is an under recognised, highly prevalent cardiovascular (CV) risk factor. Despite a clustering of conventional atherosclerotic risk factors, there is a disproportionate rate of sudden cardiac death, heart failure and stroke rather than myocardial infarction. It is hypothesised that non-atherosclerotic(More)
Methods In total, 24 patients (mean age 62 +/16 years) with degenerative moderate or severe asymptomatic MR with no class 1 indication for surgery were recruited from a dedicated valve clinic in a University Hospital and compared with gender matched controls. All subjects underwent cardiac MRI (1.5T Siemens Avanto) for assessment of LV volumes, deformation(More)
Chronic kidney disease (CKD) has been consistently associated with cardiovascular disease; there is an inverse graded relationship between glomerular filtration rate and cardiovascular risk. Early-moderate CKD receives increasing recognition for its role as an independent risk factor as evidenced by its recent inclusion in the Joint British Societies'(More)
