A newly released guideline from Hypertension Canada offers updated recommendations to help primary care providers, including family physicians, nurses, nurse practitioners, and pharmacists, better diagnose and treat hypertension.
Hypertension is the most common modifiable risk factor for cardiovascular disease and mortality, affecting approximately one in four adults in Canada. Although Canada has historically led the way in effective hypertension control, recent years have seen a decline. Contributing factors may include inconsistent blood pressure targets, the complexity of previous guidelines, and reduced engagement with front-line providers.
Since most hypertension is managed in primary care, equipping those providers with clearer, practical guidance will improve care delivery and outcomes. The actionable recommendations in this new guideline can be readily applied in everyday clinical practice.
The new guideline is grounded in the World Health Organization’s HEARTS framework, which is designed to improve cardiovascular outcomes worldwide through adaptable, country-specific strategies. When implemented in parts of the U.S., this approach helped boost hypertension control rates from 44% to 90% in just over ten years.
The recommendations reflect the latest evidence and focus on key aspects of hypertension management relevant to primary care: blood pressure assessment, diagnostic definitions, lifestyle modifications, and pharmacological treatment, including strategies for managing resistant hypertension. When selecting antihypertensive medications, the guideline committee considered multiple factors, including efficacy, side effect profile, cost, insurance coverage, availability, pill-splitting feasibility, and resilience to supply chain disruptions.
A major change in the updated guideline is the adoption of lower blood pressure thresholds for both diagnosis and treatment. These revised thresholds mean that more individuals may now be diagnosed with hypertension, which could carry personal implications, such as stigma or effects on insurance coverage. Nonetheless, the evidence strongly supports early detection and intervention to reduce long-term cardiovascular risk at the population level.
The guideline was developed by a multidisciplinary team, including family physicians, pharmacists, a nurse practitioner, hypertension specialists, and a methodology expert. Four patient partners with lived experience of hypertension contributed feedback throughout the process and helped co-design a patient support tool.
This publication is the first of two planned guidelines. A forthcoming, more comprehensive guideline will address complex and specialised aspects of hypertension care.
This guideline is not intended for all clinical scenarios. For example, it does not cover hypertension management in children or during pregnancy, where separate guidelines apply. It is designed to support the vast majority (around 95%) of uncomplicated hypertension cases encountered in community practice.
