Cardiac Energy Metabolism in Ischaemia and Heart Failure

Basic science work in this area is co-led by Dr Craig Lygate  and funded by a British Heart Foundation programme grant. We are studying the influence of cardiac energy homeostasis on ischaemic heart disease and chronic heart failure, and the potential benefits of therapies that modulate cardiac metabolism.

The heart has very high energy requirements, cycling through more than 20 times its own weight in ATP every day, and maintaining energy production and transport is fundamental to normal cardiac function. Impairment of these mechanisms plays an important role in acute ischaemic heart disease and in chronic heart failure, both major killers worldwide.

Our hypothesis is that the failing heart is energy-starved, and in the search for new therapeutic strategies we have projects encompassing aspects of substrate utilisation, phosphotransfer mechanisms, and adenine nucleotide recycling, with a major emphasis of the creatine kinase system and the creatine transporter.

Our lab employs a wide range of molecular and biochemical techniques, high-throughput cell-based assays, global gene expression profiling and live cell imaging through confocal microscopy. Functional consequences of altered gene expression are studied at the level of the mitochondria, and at the whole organ level. We have particular expertise in assessing in vivo function in the intact organism, using cutting edge methodologies and state-of-the-art facilities, e.g. high-frequency echocardiography, left ventricular pressure measurements, and in close collaboration with Dr Jürgen Schneider we have pioneered techniques for experimental Magnetic Resonance Imaging and Spectroscopy.

Clinical science work in this area uses cardiac MR spectroscopy (31P and 1H) and MR imaging to investigate cardiac energetics, lipid metabolism and cardiac function in patients with hypertrophy and heart failure, including assessment of novel forms of metabolic therapy in clinical trials.

Development and Application of Magnetic Resonance Techniques for Phenotyping of Cardiovascular Disease

Clinical research in this area is carried out on 1.5 and 3T Siemens MR systems at the University of Oxford Centre for Clinical Magnetic Resonance Research (link), where we employ state-of-the-art cardiovascular magnetic resonance methods to assess aspects of cardiac function and physiology currently inaccessible to conventional imaging methods. Examples include tissue characterization methods (e.g. T1 mapping), myocardial oxygenation (BOLD), 4D flow and 7 Tesla human imaging (7T system installed 9/11). We also apply established CMR techniques to study novel scientific hypotheses, e.g. in patients with cardiomyopathies, ischemic heart disease and heart valve disease. Examples include the development of diagnostic criteria for left ventricular non-compaction, perfusion abnormalities in hypertrophic cardiomyopathy, or assessment of irreversible myocardial injury associated with revascularization (PCI or CABG). Our clinical science programme is closely integrated with the clinical cardiac CMR service (link) for the ORH NHS Trust, providing a truly translational research environment.

State-of-the-art methods for experimental Magnetic Resonance Imaging and Spectroscopy, to non-invasively characterize experimental models, are being developed at the BHF experimental MR unit (BMRU), co-led by Dr Jürgen Schneider, using a 9.4T high-field Agilent MR system.
