Cardiovascular Medicine


The Division has assembled a collaborative group of cardiovascular investigators who collectively provide expertise in basic, translational and clinical cardiovascular research and who employ cell and molecular biology, in vivo models, genomics, epigenetics, sequencing, biomarker identification and validation, through to novel imaging, diagnostics and experimental medicine studies to improve patient outcomes. Atherosclerosis leading to myocardial infarction (MI) and stroke is the commonest cause of death in the UK. Inflammation, immunity, cell death (apoptosis), and cell senescence in atherosclerotic plaques are major contributors to atherogenesis, plaque rupture and MI. Our research examines the causes and regulation of these processes in atherosclerosis, with a particular focus on smooth muscle and immune regulation of atherosclerosis and aneurysm formation. Dr Sanjay Sinha and Dr Helle Jørgensen are studying smooth muscle cells derived from embryonic and induced pluripotent stem cells as part of the Oxbridge Centre for Cardiovascular Regenerative Medicine Centre, a network of researchers focused on cardiovascular stem cells and development.

The Division’s major clinical research interests include heart failure, the assessment of viability in dysfunctional myocardium, and the utility of transient ischaemia or novel therapeutics to protect the heart from further insults. We have developed metabolic cardioprotection during PCI (both primary emergency and elective intervention), examined the effect of new agents to treat diabetes on cardiac performance in type 2 diabetes, and determined the optimum use of cardiac resynchronisation therapy based on the underlying pathophysiology.  In our vascular imaging programme, led by Dr James Rudd, we are determining whether inflammation, hypoxia and neovascularisation detected by PET/CT and MRI can improve risk prediction, and whether imaging can illustrate the efficacy of anti-atherosclerosis drugs. Professor Bennett’s group are exploring invasive imaging of atherosclerosis using virtual histology intravascular ultrasound (VH-IVUS), and trying to determine whether plaque disruption can be predicted using stress/strain modelling. This work is undertaken in collaboration with physical scientists in the Engineering and Radiology departments of the University as part of the new Cambridge Cardiovascular Strategic Research Initiative.
