<qa>  What is the estimated value of the results?8 Expected value of results The investigators are confident that the study is adequately powered to show a 10 gm change in LVM, using MR scan at Reza Rezavis laboratory, if it exists; similarly a change in systolic function using echocardiogram at the expert laboratory at St Georges. The investigators will also be able to examine the role of fibrosis in the LVH and systolic dysfunction by measuring biomarkers at Javier Diezs laboratory. A large CKD patient population at St Georges, Guys and Kingston Hospitals will facilitate recruitment.
