A new study has revealed that most adults with conditions such as coronary heart disease, stroke, diabetes or others that raise their risk for cardiovascular complications also have hypertension (high blood pressure). The study, which examined American adults, found that nearly three-fourth of them with these conditions also had high blood pressure.
Although about 75 percent of these individuals are being treated for hypertension, only about 30 to 50 percent are reaching BP goals.
Recent estimates indicate little change in the prevalence of hypertension, and, although there seem to be some recent improvements in treatment and control rates, hypertension in many persons remains inadequately controlled, the researchers said.
Nathan D. Wong, Ph.D., of the University of California, Irvine, and colleagues looked at data from adults participating in the National Health and Nutrition Examination Survey, a nationally representative survey conducted by the Centres for Disease Control and Prevention.
In 2003 and 2004, 4,646 adults provided demographic and socio-economic information and underwent laboratory and physiological testing (including BP measurements).
It was found that a total of 1,671 (31.4 percent) of the participants had hypertension, defined as a systolic (top number) BP of at least 140 milligrams of mercury (130 milligrams of mercury in those with diabetes or chronic kidney disease) or a diastolic (bottom number) BP of at least 90 milligrams of mercury (80 milligrams of mercury in those with diabetes or chronic kidney disease), or as reporting use of a BPlowering medication.
