  • Q:

    Is it bad to have a blood pressure reading of 130/74?

    A:

    A blood pressure reading of 130/74 indicates prehypertension, according to the American Heart Association. A normal reading is less than 120 for the systolic, or top number, and less than 80 for the diastolic, or bottom number. Because 134 falls between the systolic range of 120 to 139, the blood pressure reading is indicative of prehypertension, even though the diastolic number is within normal range.
