re patients with diabetes also have worse symptoms, a higher risk of hospitalisation and a greater risk of death than those without diabetes suggesting that the underlying pathophysiology of heart failure may be different in diabetics and non-diabetics. Professor McMurray also notes an "intersection" of the two conditions by which those with diabetes have a higher risk of heart failure, and those with heart failure have a higher risk of diabetes. "But whichever is the causative factor," he adds, "it's very bad news for those with both conditions."
