My research looks at ways to reduce cardiovascular events in general practice. This is important because stroke and heart disease are the commonest causes of death and chronic disease burden. My research projects are in two major areas – stroke prevention and chronic kidney disease.
The stroke prevention work examines how we can improve the recognition of transient ischaemic attack (TIA) in primary care. Patients usually feel well after a TIA but they are at high risk of a stroke, and so accurate recognition is crucial. Healthcare systems in different countries have evolved different approaches to investigation and initiation of treatment of patients with TIA and I am collaborating with GPs and neurologists in the UK, Australia, New Zealand and North Carolina in the US to find the best care process to reduce the risk of stroke.
The chronic kidney disease (CKD) projects examine how we can best diagnose CKD, determine which patients are at increased cardiovascular risk and which treatments reduce cardiac risk and decline in renal function.
These projects will have an impact on clinical work with greater accuracy of detecting patients who need urgent assessment after TIA and determining which patients with a diagnosis of CKD will benefit from additional medication.
