Uncontrolled hypertension is defined by the American Heart Association (AHA) as blood pressure greater than 140/90 mm Hg (millimeters of mercury).
Prehypertension is blood pressure that is higher than normal but not high enough to be high blood pressure. It is a warning that your blood pressure is going up. Blood pressure is a measure of how hard your blood pushes against the walls of your arteries.Blood pressure that is too high (also called hypertension) harms your blood vessels. This raises your risk of heart attack, stroke, kidney failure, and other health problems.t is called the systolic pressure. The bottom number is the pressure when the heart relaxes and fills with blood. It is called the diastolic pressure. An ideal blood pressure for an adult is less than 120/80. High blood pressure is 140/90 or higher. Prehypertension is between 120/80 and 140/90.
