  1. Blood Pressure redefined as Prehypertension

    Washington - Researchers have renamed the category of
    normal blood pressure readings as Prehypertension. The
    Mayo Clinic Health Letter explains the recent changes
    made in the blood pressure guidelines.

    Blood pressure is the force exerted on the artery walls
    by blood flowing through the body and is important
    primarily because elevated blood pressure can put extra
    stress on the arteries and heart, thereby causing
    cardiovascular diseases.

    According to a report in NewsWise, the National Heart,
    Lung and Blood Institute released stricter guidelines for
    high blood pressure, in May 2003, because research showed
    that having blood pressure readings at the old normal or
    high-normal ranges increased the risk of developing heart

    Over a longer period of time, high blood pressure causes
    arteries to become injured or damaged and also overworks
    the heart. An overworked heart can wear out, losing the
    strength to effectively pump blood, contributing to
    serious cardiovascular concerns, explain the researchers.

    The new category, called prehypertension, covers a
    systolic range of 120 to 139 mm Hg and diastolic range of
    80 to 89 mm Hg. (Systolic pressure, the first number in
    your blood pressure reading, measures the pressure in
    your arteries when your heart beats. The second number,
    diastolic pressure, measures the pressure in your
    arteries between beats.) The new guidelines also lower
    the normal blood pressure to below 120/80 mm Hg, which
    was the old optimum level.

    Thus, if a person is in the prehypertension range, he is
    at an increased risk of cardiovascular disease. The risk
    increases steadily with the rise in the blood pressure
    within the prehypertension range.

    The guidelines however confirm that the risk can be
    reduced by making a few lifestyle changes like
    maintaining a healthy weight, eating a healthy diet,
    reducing salt intake, being more active, limiting alcohol
    and stopping smoking.
