Abstract
There is no clear separation between normal blood pressure and hypertension. Actuarial data have shown a continuous relationship between blood pressure and the probability of major cardiovascular events, but there is no agreement concerning the level of blood pressure at which a diagnosis of hypertension should be made. It is possible to suggest a functional definition of hypertension as being the lowest level of blood pressure at which therapeutic intervention could be predicted to lessen the likelihood of cardiovascular complications. In the United States, the Joint National Committee on the Detection, Evaluation and Treatment of High Blood Pressure [I] has recommended that conventionally-measured office or clinic diastolic blood pressures of 84 mmHg or less be considered normal; that 85– 89 mmHg be considered high-normal; and that levels of 90 mmHg or above define a hypertensive range that may justify treatment.
