问题             Too Many Americans Have Out-of-control High Blood Pressure
    Nearly 1 in 3 Americans suffers from high blood pressure(hypertension)and many of them don’ t have it under control, says a recent study from the Centers for Disease Control and Prevention(CDCP). According to the report,most people with uncontrolled high blood pressure have health insurance and had actually seen a doctor at least twice in the previous year, yet their condition remained unmanaged.
    Having high blood pressure is a major risk factor for heart disease and stroke; hypertensive people are 4 times more likely to die from a stroke and 3 times more likely to die from heart disease than people with normal pressure, according to CDCP director Dr. Thomas Frieden. Together, those two conditions cause nearly 1,000 deaths a day in the US and account for $ 131 billion in yearly health-care costs.
    For the report, researchers looked at 2003—2010 data to examine high blood pressure awareness and treatment among adults with uncontrolled conditions. More than 20,000 adult participants answered survey questions and received a physical exam.
    The data suggest that some 67 million Americans have high blood pressure,and nearly 36 million of them don’t have their condition under control. Among those, about 14 million don’ t know they’re hypertensive,nearly 6 million are aware but not receiving treatment, and 16 million know they have high blood pressure and are receiving medication for it but still don’t have their pressure under control.
    "We have to roll up our sleeves and make high blood pressure control a priority every day,with every patient at every doctor’s visit," said Frieden.
Compared with people with normal pressure, hypertensive people are______.
