    Midlife Blood Pressure Predicts Future Heart Risk

    High Blood Pressure in Middle Age Linked to Later Heart Attack, Stroke

    Dec. 19, 2011 -- Increases and decreases in blood pressure during middle age and even earlier in adulthood can significantly affect heart attack and stroke risk later in life, a new study shows.

    The analysis of data from seven studies involving more than 61,000 people is one of the most comprehensive studies ever conducted examining how changes in blood pressure during middle age affect lifetime risk of heart disease and stroke.

    Researchers confirmed that people with normal blood pressure at age 55 had a relatively low lifetime risk for heart disease or stroke -- between 22% and 41%.

    In contrast, those who had already developed high blood pressure by this age had a higher lifetime risk of between 42% and 69%.

    The findings highlight the importance of maintaining normal blood pressure throughout middle age and even earlier, says researcher Norrina Allen, PhD, of Chicago’s Northwestern University Feinberg School of Medicine.

    More than 74 million adults in the U.S. have high blood pressure, meaning that their systolic pressure (the top number) is 140 mmHg or higher and their diastolic pressure is 90 mmHg or above.

    “People who maintained a low blood pressure of less than 120 over 80 had the lowest lifetime risk for [heart disease and stroke], and those who stayed above 140 over 90 had the highest,” Allen tells WebMD. “The longer people can delay the onset of hypertension, the better off they are.”

    Middle-Age BP Predicts Heart, Stroke Risk

    Using the data, the researchers were able to estimate lifetime risk for heart attack, stroke, and other heart-related events for white and African-American adults.

    Starting with a first-time reading at an average age of 41, the researchers tracked blood pressure changes until age 55 and then continued to follow the study participants until the occurrence of a heart attack, stroke, or other medically similar event, or until death or age 95.

    By their mid-50s, about one in four men and two in five women still had normal blood pressure, and about half of men and women had blood pressure that was above normal but not yet high enough to be considered high.
