A systolic blood pressure over 140 mm Hg is an important risk factor for stroke and heart disease. read more

She’ll say the numbers as systolic pressure “over” diastolic pressure. For example, a healthy reading is below 120 over less than 80. If your systolic blood pressure is higher than 130 but your diastolic blood pressure is under 80, that’s called isolated systolic hypertension. read more
