According to the American Heart Association, more than 78 million adults in the United States have high blood pressure, which is blood pressure higher than 140/90 mmHg.
Among these adults, about 9 percent have resistant hypertension, which means that even taking three or more medications to control their blood pressure, it remains higher than 140/90 mmHg.
