Cardio-renal clinical study group
Patients with kidney failure are at a very high risk of heart disease, including heart attacks and stroke, compared to the general population. This risk starts even when kidney function is only slightly abnormal and increases dramatically in patients who need dialysis.
Although some of this risk is explained by well-known risk factors such as high blood pressure and diabetes, this does not account for why patients with kidney disease are at such high risk. Further research to explain this, and develop better treatments is required.
Who we are
We are a national group dedicated to initiating and supporting clinical research in the cardio-renal field.
The group is led by Co-Chairs, Dr Tim Doulton, Consultant Nephrologist at East Kent Hospitals University NHS Foundation Trust Renal Unit, and Dr Matthew Graham-Brown, Associate Professor of Renal Medicine, University of Leicester and Honorary Consultant Nephrologist at University Hospitals Leicester.
We are delighted to have new members, and are interested in studies proposed from out with the group.
- Developing a better understanding of and treatments for the cardiovascular complications of chronic kidney disease (CKD).
- Addressing why patients with kidney disease are at such a high risk of heart problems (approximately 20 times higher than the general public of the same age).
- Learning more about why patients with primarily cardiovascular disease develop kidney problems and to find better treatments to prevent this or manage this better.
- Undertaking multicentre, collaborative studies and clinical trials in cardio-renal medicine to improve cardiovascular outcomes for patients with kidney disease. Evidence gaps and challenges:

Publications arising are listed below.
The studies above are helping define the best treatment strategies to prevent cardiovascular problems in patients with chronic kidney disease by using statins or medications used for heart failure or treating high blood pressure. They have informed National and International guidelines with a direct and measurable impact on patient care. In future studies we will explore different options such as vitamin k therapy or exercise programs to see if they provide additional benefits and help reduce the risk of heart disease risk in patients with kidney failure.
