abstract：:While only a small percentage of the population has high blood pressure, a much larger segment of the US population has a high-normal (above optimal) blood pressure, and is at increased risk for hypertension and its cardiovascular sequelae. Hypertension is thus a population-wide problem and must be approached in much ...
