This is in regard to the July 13 Dr. Donahue column regarding goals for blood pressure treatment.

The doctor commented that “If the systolic blood pressure, the first number, lies between 140 and 159 and the diastolic pressure, the second number, is less than 90, more medicine is not needed.”

Actually, the most recent recommendations for blood pressure treatment, published in 2003 by a panel of experts known as the “Joint National Committee on Prevention, Detection, Evaluation and Treatment of High Blood Pressure,” differ significantly from the information presented by Dr. Donahue.

The current definition of normal blood pressure is a systolic pressure less than 120 and a diastolic pressure of less than 80. It is recommended that medications be started if the systolic blood pressure is persistently greater than or equal to 140 or the diastolic pressure is persistently greater than or equal to 90. The goal for treatment is to keep the systolic blood pressure below 140, and the diastolic blood pressure should be kept below 90.

In the case of an individual with cardiovascular disease, diabetes or kidney disease, these goals are lowered to a goal blood pressure of less than 130/80.

It is estimated that for every increase in blood pressure of 20 points above 115/75, the risk of heart attack and stroke doubles.

As we work to decrease the burden of these illnesses, we must present the public with accurate information which can lead to informed choices and decisions.
