[Current management of arterial hypertension].

Hypertension is a common health problem with serious consequences for individuals and a heavy attributable burden for populations. Reducing this burden requires preventive actions at the population level and early diagnosis at the individual level, followed by proactive interventions with proven benefits. Given the variability of blood pressure measurement, diagnosis is established only after repeated measurements under standardized conditions, if possible outside the clinic. Lifestyle changes can modestly reduce blood pressure; their impact is significant if they can be achieved on a large scale. Hypertension treatment requires a rational pharmacological approach, which can reach the target blood pressure within less than 6 months and three pharmacological classes at most in more than 80% of cases. Specialized consultation is required in the remaining 20% to detect secondary hypertensions, to optimize drug therapy and to discuss, in a minority of cases, non-pharmacological treatments. Recommendations are written by experts who select, interpret, and extrapolate the results of clinical research. As a consequence, they are sometimes unsuitable for primary care practice and frequently inconsistent across guidelines. Efforts are currently made to produce less disputable and more usable guidelines.
