FREQUENCY FREQUENCY of arterial hypertension (AH)of arterial hypertension (AH)
AP > 140/90 mm Hg
20-30 % in population20-30 % in population At elderly people - 45-50 %At elderly people - 45-50 %
Principles of treatment of arterial hypertension 1. Treatment should be started as soon as possible and should be hold till the end of
life. Canceling antihypertensive drugs administration causes relapse of AH.2. All the individuals with increased arterial pressure should obtain drugless treatment
(modifying lifestyle):-rejection from smoking and alcohol;-increasing of physical activity;-restriction of salt consumption (less than 6 g per day);-decreasing of body weight in a case of obesity.
3. Scheme of drug treatment should be the most availably simple – 1 tablet per day if possible; it is better to use drugs with long duration of action (prophylaxis of considerable fluctuation of blood pressure during the day).
4. Rapid decreasing of blood pressure to low figures is dangerous, especially for elderly patients.
5. Main aim of the treatment is to decrease blood pressure to 140/90 mm Hg. To improve life prognosis is the aim that has a more significant meaning than character of drugs used to reach this aim. It is better to prescribe cheap and “non modern” drugs than don’t treat the patient at all.
