1989 guidelines for the management of mild hypertension: memorandum from a WHO/ISH meeting.

The present guidelines were prepared by a subcommittee of the WHO/ISH (International Society of Hypertension) Mild Hypertension Liaison Committee, and wee finalized after discussion at the Fifth WHO/ISH Mild Hypertension Conference. They include the definition of mild hypertension, and describe blood pressure measurement, factors influencing the decision to begin treatment, methods of treatment, and follow-up. These guidelines are a revision of those published in 1986; they are based on the best available scientific evidence, and will be updated in the future to keep abreast of further developments in this field.
