New York: It`s the leading contributor to deaths worldwide yet most people with high blood pressure don`t know they have the condition and even for those who do, treatment is mostly ineffective, according to a large new study.Researchers examined more than 140,000 adults in 17 countries and found that about 41 percent had consistently high blood pressure, also known as hypertension, but fewer than half of those people knew it."We found that surprisingly many people didn`t realize their blood pressure was high," lead author Clara Chow, from The George Institute for Global Health in Sydney, Australia, said.Less than a third of those aware of their condition and getting treatment had their blood pressure under control, with poor and rural populations faring the worst."Whereas in high-income countries a larger proportion of people knew they had hypertension and were on treatment than people in low-income countries, the control problem was significant wherever you were," Chow said.
