SUMMARY
At the begining of a new millennium, more than 50% of people, 65 years of
age or older, have arterial hypertension. According to the frequency of
physician visits, arterial hypertension occupies the first place among all
chronic diseases. Numerous studies have showed that good control of hypertension
significantly reduced the risk of both cardiovascular morbidity and mortality.
In recent years, several quidelines on diagnosis, examination and treatment of
patients with arterial hypertension have been published. The aim of this paper
is a short review of European guidelines for the management of arterial
hypertension (European Society of Hypertension - ESH and European Society of
Cardiology - ESC), which was published in 2003.
Normal values of systolic blood
pressure are up to 139 mmHg and for diastolic pressure up to 89 mmHg. There are
three categories of normal blood pressure: optimal, normal and high normal.
There are three stages of arteraial hypertension: mild, moderate and severe,
while isolated systolic hypertension is separated (systolic blood pressure 140
mmHg and diastolic < 90 mmHg). European guidelines contrary to JNC 7 (American
guidelines for hypertension) do not suggest a term "prehypertension" for
individuals with systolic blood pressure 120 - 139 mmHg or diastolic 90 - 99
mmHg. Risk stratification is an important part of recommendations and it was
done according to the presence of other risk factors, target organ damage and
rejoined diabetes as well as other clinical conditions. In order to diagnose
arterial hypertension, apart from anamnesis and clinical examination with
repeated blood pressure measurements, it is necessary to include some
laboratorial tests which may be routine, recommended or expanded (for more
complicated forms of hypertension or for determining the cause of secondary
hypertension).
The primary goal of arterial
hypertension treatment is to achieve maximal reduction of global cardiovascular
risk for morbidity and mortality. Blood pressure values should be reduced to
less than 140/90 mmHg; in diabetic patients it should be reduced under 130/80
mmHg. The decision for the treatment onset refers to initial values of blood
pressure and global cardiovascular risk as well. In the treatment of patients
with arterial hypertension the change of lifestile is necessary and enough in
some cases (to give up smoking, body - weight reduction, excessive alcohol
intake, regular aerobic physical activity, less salt intake and increased intake
of fruit and vegetables). If the expected values of blood pressure are not
reached by applying the measures of changed life style, a therapy by drugs is
introduced. If blood pressure values are high or if the risk is high, the
measures of changed life style are applied along with medicaments. In relation
to cardiovascular risk, presence of target organ damage, rejoined clinical
conditions and cost of drug, some of five major classes of antihypertensive
agents: diuretics, beta - blockers, calcium antagonists, ACE inhibitors and
angiotensin receptor antagonists is chosen. In specific indication alfa -
blocker may also be recommended.
