  • Research summary

    Chronic kidney disease is associated with an increased risk of heart problems and death. The causes of these increased heart problems are not fully understood, but are thought to include inflammation, scarring and increased heart muscle thickness. It is increasingly recognised that problems with the very small blood vessels that supply the heart may play a role in heart muscle diseases. This has been shown in other heart conditions that share similarities with the changes in the heart seen in kidney patients.

    Our study aims to assess the function of these very small blood vessels that supply the heart muscle in patients with chronic kidney disease. We will do this using specialised ultrasound measurements. The techniques to do these measurements are not widely used in the UK so initially we will do a pilot study to ensure that they are feasible and gain data on coronary flow reserve values in a UK population. Based on the pilot study, we will then perform a larger study using these techniques.

    If we demonstrate that patients with kidney disease have dysfunction of these small vessels and that this causes the abnormal changes in the heart, in future, treatments may be developed to target this mechanism. This will help to reduce the risk of heart problems in patients with kidney disease.
