High blood pressure (also known as hypertension) is a major risk factor for cardiovascular disease (CVD) including premature heart attacks, strokes, heart failure and blockage of major blood vessels in the legs. People with diabetes are also at risk from high blood pressure and, if blood pressure is not treated appropriately, other serious complications of diabetes including vision loss and kidney failure. Many adults in the US have hypertension, including the 1 in 9 Americans with diabetes, and blood pressure is often not well controlled. Blood pressure is usually measured when you visit your doctor. Sometimes, the anxiety of a doctor appointment can cause the blood pressure readings to be higher than normal. The name for this is “white-coat hypertension.” Research has shown that measuring blood pressure at home provides very valuable information for diagnosing and managing hypertension and reduces the risk of errors from white-coat hypertension. Therefore, self-measured blood pressure monitoring should be supported and, as telehealth grows, monitoring blood pressure at home will become more common.
