[Summary of the practice guideline 'Hypertension' (third division) from the Dutch College of General Practitioners].

The revised practice guideline on hypertension from the Dutch College of General Practitioners has been brought in agreement with the guideline on hypertension from the Dutch Institute for Health Care Improvement. The main changes with regard to the former edition are: The threshold values for the diagnosis 'hypertension' have been lowered to 140 mmHg and 90 mmHg for the systolic and diastolic blood pressures, respectively. Annual screening for hypertension in the elderly is no longer recommended. Henceforth, blood pressure measurement once every five years is considered sufficient, unless the blood pressure is known to be in a borderline area in which treatment is being considered. Often, the decision as to whether a patient should take antihypertensive drugs no longer depends on the presence of hypertension as such: to receive drug treatment, the patient should have at least a 20% risk of developing a cardiovascular disease in the next 10 years. To aid in estimating this risk for individual patients a risk table has been devised. Diuretics and beta-blockers are the drugs of first choice. If the blood pressure remains too high, angiotensin-converting-enzyme (ACE) inhibitors and calcium-channel blockers may be added.
