Integrated Brain-Heart-Mental Health Care: A Review of the 2026 C-CHANGE Guideline

In March 2026, the Canadian Cardiovascular Harmonized National Guideline Endeavour (C-CHANGE) published the first Canadian clinical practice guideline to jointly address brain, heart, and mental health conditions, replacing the disease-specific silos that had previously left family physicians without unified guidance for patients carrying multiple, interacting chronic conditions. This review synthesizes that guideline for a Canadian primary care audience, examining in turn its recommendations for managing heart failure and atrial fibrillation in patients with comorbid cognitive impairment, its guidance on cognitive screening and silent cerebral infarct detection in cardiac patients, its proposed integrated care pathway linking cardiology, neurology, and mental health services, and its shared decision-making framework for reconciling competing treatment priorities. The evidence indicates that cognitive status materially changes cardiac management decisions, that brief validated screening tools can identify at-risk patients within a standard visit, and that team-based models such as the Patient's Medical Home already provide much of the infrastructure the guideline's integrated pathway requires. What remains incomplete is implementation: screening tools, referral pathways, and electronic medical record supports exist individually but are rarely deployed together in the same practice. Family physicians are positioned to close that gap and are the clinicians most likely to see these patients before either a cardiac or neurologic event forces a reactive referral. Moving this guideline from publication into everyday Canadian family practice will require deliberate investment in the team-based infrastructure that makes integrated, patient-centred brain-heart care practical rather than aspirational.
