The incidence of high blood pressure rises with age. Half of all Americans 55 and older have high blood pressure rising to 63 percent after age 65. Three-fourths of African Americans over 65 have it.
High blood pressure is above 140 systolic pressure (upper number) and/or 90 diastolic (lower number).
People with high blood pressure are 3 to 4 times more likely to have a stroke. Dropping 11 systolic points or 5 diastolic points cuts stroke risk 40 percent.
