High normal blood pressure and prehypertension: the debate continues

Abstract
in English, French

Subjects with high normal blood pressure are at high risk of developing hypertension. Thus, the criteria of the Canadian Hypertension Education Program for diagnosis of hypertension and recommendations for follow-up now recommend that patients with high normal blood pressure (130 mmHg to 139 mmHg systolic and/or 85 mmHg to 89 mmHg diastolic) be followed up annually for the development of hypertension. Clinical trial data from subjects with high normal blood pressure show that 40% over two years and 63% over four years developed hypertension (140/90 mmHg or higher). These data are consistent with observational data from the Framingham Heart Study, which found a similar risk. Besides annual follow-up, the Canadian Hypertension Education Program recommends lifestyle therapy for individuals with high normal blood pressure. Ongoing research will establish whether any further management is required.

Les personnes ayant une pression artérielle (PA) normale élevée sont fortement prédisposées à l’hypertension artérielle (HTA). C’est pourquoi on recommande dans les critères relatifs au diagnostic d’hypertension et les recommandations sur le suivi, exposés dans le Programme d’éducation canadien sur l’hypertension, que les patients présentant une PA normale élevée (PA systolique : 130 – 139 mm Hg ; PA diastolique : 85 –89 mm Hg) soient suivis chaque année afin de déceler l’apparition d’HTA. D’après des données d’essais cliniques, 40 % et 63 % des personnes ayant une PA normale élevée sont atteintes d’HTA au cours des deux et quatre années suivantes, respectivement (≥ 140/90 mm Hg). Ces données vont dans le même sens que les données d’observation de l’étude de Framingham, qui révèlent un risque comparable. En plus du suivi annuel, il est recommandé, dans le Programme, que les personnes présentant une PA normale élevée modifient leur mode de vie. La poursuite de la recherche permettra de déterminer si d’autres mesures s’imposent.
