High blood pressure (hypertension) can cause such problems as heart attack, heart failure, kidney failure, and stroke. Lowering blood pressure helps to prevent these problems; unfortunately, even persons who are getting health care often do not reach healthy blood pressures. Blood pressure treatments include diet, exercise, and drugs. Many people find it hard to follow diets, exercise regularly, or take medicines daily, and because patients usually feel well even with very high blood pressure, many patients with hypertension do not understand the importance of lowering their blood pressure. New ways to motivate patients with hypertension to follow diet and exercise advice and to take their medication as prescribed would be useful.
