The 2017 American College of Cardiology/American Heart Association vs Hypertension Canada High Blood Pressure Guidelines and Potential Implications

      Abstract

      In this report we examine the differences between the 2017 Hypertension Canada and 2017 American College of Cardiology and American Heart Association (ACC/AHA) blood pressure (BP) guidelines regarding the proportions of individuals with a diagnosis of hypertension, BP above thresholds for treatment initiation, and BP below targets using the CARTaGENE cohort. Compared with the 2017 Canadian guidelines, the 2017 ACC/AHA guidelines would result in increases of 8.7% in hypertension diagnosis and 3.4% of individuals needing treatment, with 17.2% having a different BP target. In conclusion, implementing the 2017 ACC/AHA hypertension guidelines in Canada could result in major effects for millions of Canadians.

      Résumé

      Dans ce rapport, nous analysons les différences entre les lignes directrices de 2017 d'Hypertension Canada et celles de l'American College of Cardiology et de l'American Heart Association (ACC/AHA) en matière de pression artérielle (PA) pour déterminer les proportions d'individus ayant reçu un diagnostic d'hypertension et présentant une PA supérieure aux seuils d'instauration d'un traitement et une PA inférieure aux valeurs cibles dans la cohorte du projet CARTaGENE. Comparativement aux lignes directrices canadiennes de 2017, l'application des lignes directrices de l'ACC/AHA se traduirait par une augmentation de 8,7 % du nombre de diagnostics d'hypertension et de 3,4 % du nombre de personnes nécessitant un traitement, dont 17,2 % auraient une PA cible différente. En conclusion, la mise en œuvre au Canada des lignes directrices de 2017 de l'ACC/AHA sur l'hypertension pourrait avoir des répercussions majeures pour des millions de Canadiens.
