Besides being a huge risk factor for heart disease, strokes, etc, high blood pressure can also lead to kidney disease. People with high blood pressure are at risk of developing changes that lead to scarring inside the kidneys, that could ultimately cause the kidneys to "burn out". Patients with existing chronic kidney disease (CKD), are at a higher risk of progression to end stage kidney disease when they would need either dialysis or a kidney transplant, should their blood pressure stay high/uncontrolled. In fact, after diabetes, high blood pressure is the commonest reason that people develop kidney failure. So what is the target blood pressure for someone with underlying CKD to minimize their risk of progression to end stage kidney disease?
