Abstract
Though the data from the most recently completed National Health and Nutrition Examination Survey III (1988 through 1991) has enabled us to revise downward (from 58 million to 50 million) earlier estimates of how many Americans have hypertension (a systolic blood pressure of 140 mm Hg or greater and/or a diastolic blood pressure of 90 mm Hg or greater, or taking antihypertensive medication), high blood pressure remains the most common reason that we seek medical attention in this country.1The overwhelming majority of these patients, perhaps as many as 60%, have what was called "mild" hypertension and is now more appropriately designated as stage 1 hypertension (properly measured and confirmed systolic blood pressure of 140 to 159mm Hg or diastolic blood pressure of 90 to 99mm Hg).2There is little question that both men and women with these seemingly modest elevations of blood pressure are at substantially greater
