The kidney-heart connection

More than one in seven adults has chronic kidney disease, yet many of them aren’t aware of the problem. Early-stage kidney disease often has no symptoms, but the condition slowly and silently worsens over time. The two most common causes of chronic kidney disease—high blood pressure and diabetes—are also leading risk factors for heart disease, which means the two diseases often overlap. Most people know their blood pressure and cholesterol values, but few are familiar with the tests used to assess kidney health. They include serum creatinine, estimated glomerular filtration rate, and urine protein tests.
